A pair of low pressure systems to our south today will consolidate
into an intense nor'easter just east of the mid-atlantic coast on
Wednesday, then pass southeast of nantucket island Wednesday night.

A blustery cold northwest flow follows in its wake Thursday and
Friday. Canadian high pressure builds in to start the weekend.

Another low pressure system may pass to our south early next week.

Near term through Wednesday
More freezing rain is has occurred across SE nj and into cntrl
delaware this evening. The wsw warning that was to go into
effect at 6 a.M. Has been brought back in time to now. A light glaze
ice is expected overnight in these areas then significant snows
expected Wednesday.

A mixed bag of precipitation is encompassing much of the area
this afternoon, with combination of snow sleet freezing rain
beginning to accumulate on paved and non-paved surfaces west of
the delaware river and at least on elevated surfaces in
central southern new jersey. Plain rain dominates south of kent
county md de and in CAPE may county, nj. Travel impacts are
beginning to occur. As such, feel that ramping up the start time
of the winter storm warning to the present is a good idea,
generally between i-80 and new castle queen anne's counties.

However, I delayed the start time of the warning until 6 am for
far northern new jersey and for the rest of delmarva, where
precipitation will either be sparse (north) or mostly liquid
(with temps above freezing; south).

The evening commute may be difficult, especially near west of
philly, where quick bursts of snow sleet freezing rain have
already caused some problems. Several reports of 0.5-2 inches of
snow sleet accumulation have been received, and several asos
sites are reporting freezing rain mixing in with the snow sleet
(including ilg and phl). Worried that some roads will become
quite hazardous during rush hour.

Updated grids expanded freezing rain mention along the
i-76 i-95 i-295 corridors. Also lowered temperatures a little
bit, since wet bulbing was still keeping temps lower than what
models are insisting upon.

Meanwhile, wind gusts 40-50 mph are ongoing in sussex county in
delaware and CAPE may atlantic counties in nj. Wind advisory
looks good. Based on delaying the winter storm watch here, may
end up extending the wind advisory through the night to account
for the continued wind threat. So far, though, have kept the
advisory through 6 pm.

Short term Wednesday through 6 am Wednesday
Potent vort MAX moving through the ohio tennessee valleys this
afternoon will pivot into more of a negative tilt overnight,
with considerable large-scale ascent downstream in much of the
mid-atlantic. Downstream surface low off the coast will be
absorbed overtaken by a strengthening kicker vort MAX late
tonight. Long-duration onshore flow and low-level isentropic
lift will occur north of the low in the northern mid-atlantic.

This should permit continued precipitation in much of the area
tonight, though some gradual lessening of rates will occur as
the strongest deepest lift with the predecessor vort MAX moves
out of the area. However, another ramp-up will likely begin by
the end of the night in the region as considerable differential
cyclonic vorticity advection begins, aided by left-exit region
upper-level divergence as a cyclonic jet streak reaches the
southeast coast.

As mentioned above, precipitation during the late evening and
early overnight hours will become somewhat lighter and
potentially even drizzly. This is concerning, because this may
permit liquid precipitation to expand northward westward as the
precipitation intensity lightens. With temperatures near or even
below freezing, freezing drizzle rain may become more
widespread between the i-195 and i-76 corridors this evening and
in northern central DELMARVA through much of the overnight. I
expanded icing potential considerably during the evening early
overnight hours, with potential for up to tenth-of-an-inch
accumulations, especially in far southern new jersey and
northeast md northern de. Just how far south this threat expands
is a tough question, as temperatures should stay marginal in
the dover stevensville areas southward. This may require
frequent grid edits overnight, based on nowcasting.

The precipitation will ramp up again late, and dynamic cooling
aided by considerable large-scale lift should get the snow
machine cranking from west to east late in the night. The main
show will begin tomorrow.

For temps dew points, used a blend of 2-m nam ECMWF with only
some weighting to the previous forecast, given these models'
generally superior performance during the past 12 hours.

Winds at the coast may stay elevated overnight, which may
require extension of the wind advisory. Winds will likely stay
elevated tonight -- I kept gusts 25 to 30 mph through much of
the area, and they may actually remain higher than this in the
higher terrain, especially late.

Long term Wednesday through Tuesday
The following is stated with a request to please check back on
our 4 am products tomorrow morning. But as of this writing... We
continue to need to sound the siren for major or extreme impact
for the i95 corridor to i80 Wednesday afternoon and night.

Major and dangerous probable record breaking march winter snow
storm (pasting!) for both the 2 day total and the month of
march for parts of our area (nnj for the month, phl the storm)
with impassable roads expected and possibly the greatest number
of power outages from any storm so far in march. This continues
to look huge and potential extreme impact i95 corridor up to

Take this storm seriously and prepare for changing your daily
plans, especially Wednesday. Unnecessary travel is not recommended
Wednesday in eastern pa and the northwest two thirds of nj. It
could be life threatening if disabled in rural areas. If you
have to travel, plan for much much longer commutes. Potential
exists widespread cancellations in eastern pa and much of NW nj.

This forecast today was split between myself Wednesday through
Friday, and lance, Friday night through the weekend.

Growing 12z 20 model consensus (exception the seemingly lagging
op 12z 20 ecmwf?) with heavy reliance on the NAM 12 and 3km as
well as the bountiful model QPF from the rgem ggem, ukmet.

We expect widespread 1 to 3 inches of QPF from this, heaviest se
pa thru northern and central nj, banding will be a huge
contributor. The northwest fringe of our area from kmpo to high
point may escape with only 6 to 10 inches of snow but it is now
expected that widespread storm totals 10-20" will occur i95
corridor nwwd with isolated 25 inch amounts possible some where
between i95 and and i80... Probably best chance hilly areas of
northern nj where some 30 inches has already occurred this

The forecast snow total map includes todays sleet snow mix and
the anticipated much greater snowfall on Wednesday. Please
realize that pavement amounts will be considerably less but we
expect at least 7 inches on all pavements in nj E pa from this
storm as a minimum and at least 3" pavements elsewhere to the se
of i95. We forecast for the traditional accumulating surfaces
including homes trees wires and that is what will cause the
power outages... Ie 6" or more of wet snow (32-33f) should
trigger a sharp increase in power outages Wednesday afternoon.

Also wind driven wet snow or freezing rain clinging to branches
and wires will be part of the power outage problem. Our forecast
amounts are presented on our winter wx page and social media
briefing packages serves as a good start! Have been
uncomfortable forecasting these amounts the past two days in our
area, late season and what not, but the recent advances in
modeling and snow forecasting science tells us these amounts
are probable including running QPF from snow ratios.

Wednesday and Wednesday night through 2 am Thursday... By 00z 22
(Wednesday evening), our forecast area will have been in
constant 3 to 4 standard deviation 850mb easterly flow with
pretty high values of moisture flux for 24hours!!, beginning
late this afternoon and continuing through Wednesday afternoon.

This less extreme easterly flow inflow might normally mean less
qpf, but the unusually long duration has to make up for the
normally faster newd movement of the 850mb ely inflow. I think
this justifies the NAM and ggem QPF and resultant excessive late
season snowfall.

As the 500 mb associated heights lower, whatever remains of the
remaining above freezing 880-800mb layer is cooled to freezing
around 12z Wednesday along and NW of i95, and any mixed
precipitation will change to snow. (we think the NAM warm nose
is a bit overdone but respect it becoming more pronounced this
evening before cooling tomorrow morning).

Bands of cirrus will increase the seeding potential (potential
thunder snow) and there is considerable agreement that fgen
banding will develop on the northwest periphery of the deepening
mid atlc coast cyclone. That will mean 1-3" hr accumulations at
times Wednesday afternoon and evening, especially i95 westward.

This with snow water ratios of 11 or 12 to 1 E pa and nnj (near
9 or 10 to 1 i95 should result in record breaking (see climate
section). If thunderstorms occur (we saw lightning in clouds in
nw va and around 11z and recently SE of dc around 1320z), then
we may have a repeat of 3-4" hr snowfall rates. There is still
uncertainty on whether thunder will occur.

Strong winds, with gusts around 45 mph, primarily along the coast,
and primarily during the morning. This will could cause power
problems, especially if there is already a snow load on trees
and power lines. The strongest winds may occur before the heaviest
snow, although that is still somewhat uncertain. I also don't
think these strong winds will contribute too much to blowing
snow prior to the evening commute. This will be a very heavy
wet snow which should limit the blowing snow threat until
sundown Wednesday. For now consider this heart attack - power
outage snow, pasted street signs.

Late Wednesday night after 2 am Thursday... Snow tapering off
late with gusty northwest winds to 25 mph.

Thursday and Friday... Blustery and cold with northwest winds
gusting to 35 mph during the day and a little less at night.

Blowing snow. The snow pack could limit day time heating, so
have gone with the lower side of guidance for highs each day.

One note: a sewd moving cold core across our area seems likely
to trigger sct snow showers and there is a snow squall signal so
the hilly areas of NE pa and NW nj may pick up a a little bit of
a dusting.

Friday night through Tuesday... The mid-level large scale
features include additional energy digging into the western
conus trough, which amplifies a downstream ridge over the
central conus, while high latitude blocking INVOF the davis
strait continues to trend down. This continues to influence the
axis and amplitude of the trough across the northeast CONUS and
southeast canada, and the shortwave disturbances moving through
this feature, as it gradually closes off well south of nova
scotia early next week. There remains disagreement in the
deterministic and ensemble solutions regarding low pressure
tracking from the great planes on Saturday, with redevelopment
off the mid-atlantic coast Sunday and into Monday.

The trend has been to suppress the low further to the south, yet the
extent of dry air associated with a high pressure ridge axis located
east of the appalachian mountains remains in question, and therefore
the northward extent of overunning precipitation associated with this
system. Wpc has also noted the lack of deterministic and ensemble
run to run consistency, and is favoring a blended approach of today's
06z GEFS and 00z ecens. While this would focus precipitation across
portions of eastern pa and DELMARVA from late Saturday into at least
Sunday, it could certainly be more widespread across the remainder of
the area, given the level of uncertainty.

In addition, an early look at some of the mass fields indicates an
environment favorable for wintry precipitation outside of southern
delmarva, especially Saturday night. For Sunday, there is a lot of
disagreement in temperatures, e.G., evaporative cooling effects
and dynamical cooling, particularly during the final week of march
with the increasing Sun angle.

Bottom line... There is still the potential for wintry precipitation
to accumulate across much of the area late Saturday into Sunday.

Renewed coastal flooding is also possible depending on the strength
and duration of onshore flow. Furthermore, any impacts realized
this weekend could inhibit recovery efforts from the ongoing
storm system (e.G., power restoration).

Looking ahead to Tuesday, the pattern is favoring a return to fair
weather with temperatures at or above average.

Aviation 01z Wednesday through Sunday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Low pressure developing off the mid-atlantic coast will bring gusty
ne winds and a mixed bag of wintry precip to the area through
tonight and Wednesday. So far this afternoon it has been mostly rain
at miv acy, mostly snow at rdg abe and a mix in between for
ttn phl ilg.

For the rest of this afternoon and tonight... Fairly light mixed
precip should continue over the area with MVFR to occasional
ifr conditions. Confidence in precip type and timing is below
average. There should be a lull in precip during the evening
into overnight resulting in better vsbys. Winds will remain from
the NE and rather gusty, especially towards the shore (i.E.,


Wednesday and Wednesday night... Ifr and lifr conditions
especially during Wednesday afternoon and evening in snow,
which should be heavy at times. The change to all snow occurs
at kmiv and kacy during late Wednesday morning. We may see some
gradual improvement late Wednesday night (after 06z 22).

Northeasterly wind Wednesday becoming northwesterly Wednesday
night with gusts 20 to 30 kt. Wednesday morning, gusts up to 40
kt possible at kacy. High confidence.

Thursday and Friday...VFR with northwest wind gusting to 30 kt,
especially day time. Blowing snow where accumulations are still
more than 2 inches which should be most TAF sites.

Friday night through Saturday...VFR conditions expected. Northwest
winds around 10 kts. Moderate confidence.

Saturday night and Sunday... MVFR possible in low clouds and possible
wintry precipitation at all terminals. Low confidence. North winds
shifting to northeast 10 to 20 kts.

Storm warning through tonight except for upper delaware bay,
where a gale warning is in effect. Northeast winds nearing
storm force now and will continue on and off through the night.

Seas will be building through the period, likely reaching 15+
feet in the delaware southern nj atlantic waters by dawn. Waves
of 3-7 feet are possible in delaware bay.

Rain (possibly mixing with sleet and snow near the coast) will
continue for much of the night, with visibility restrictions


Wednesday... Intermittent storm force conditions most of the
atlantic coastal waters and lower de bay with a NE wind
Wednesday. Intermittent gale conditions on upper de bay.

Wednesday night... Northwest flow with winds and seas slowly
subsiding to gale and then possibly SCA by Thursday daybreak.

Thursday through Friday... SCA northwest flow.

Friday night - Sunday...

sca conditions are expected in a northwest flow on Saturday,
then continuing into Sunday, as winds veer to the northeast.

Tides coastal flooding
A strong northeast wind continued along the coasts of new jersey and
delaware at mid afternoon. The surge had already built to around 1.5
feet along the coasts of sussex county, delaware and CAPE may
county, new jersey. The surge was lagging a bit along the northern
part of the new jersey coast. The across-water fetch there is
limited by long island and southern new england. The surge was
running around a half foot in the sandy hook vicinity.

We will not be making much change to the total water level forecasts
for our tidal areas. We will continue to favor the more robust etss
due to the strength of the coastal storm. The etss has remained
rather consistent from run to run over the past couple days.

The coastal flood warning for the new jersey counties of ocean,
southeastern burlington, atlantic, CAPE may and cumberland, and for
the delaware counties of sussex and kent remains in effect. The
warning runs from 8:00 pm this evening until 5:00 am Thursday to
cover all three high tide cycles of concern.

The coastal flood advisory for monmouth county and middlesex county
remains in effect from 9:00 am Wednesday until 5:00 am Thursday. Due
to the lag in the surge there, those areas are forecast to fall
short of the minor flooding threshold tonight and they should
experience widesperad minor flooding but little or no moderate
flooding on Wednesday and Wednesday night.

The surge is forecast to push up delaware bay and into the far lower
delaware river, impacting the high tides there on Wednesday and
Wednesday night. A coastal flood advisory is in effect for new
castle county and salem county from noon on Wednesday until 5:00 am

The surge is expected to build around 1.0 to 1.5 feet from long
beach island northward, and close to 2.0 feet from the atlantic city
area southward for tonight's high tide. Minor flooding should begin
from long beach island southward at that time.

The surge for the Wednesday high tide is forecast to be in the 2.0
to 3.0 foot range. It is expected to produce moderate coastal
flooding along much of the new jersey coast, the delaware coast and
delaware bay. The exception should be the northern part of the new
jersey coast where widespread minor flooding is anticipated. Also,
minor flooding should reach the the far lower part of the delaware

The wind is forecast to transition from north to northwest on
Wednesday night. However, water is expected to remain trapped along
our coast and we are anticipating another round of surge levels in
the 2.0 to 3.0 foot range. The degree of flooding is expected to be
similar to that on Wednesday.

At this point, only spotty minor flooding is anticipated for the
tidal delaware river between the commodore barry bridge and trenton.

No tidal flooding is expected for the upper eastern shore of
chesapeake bay.

Record breaking march snowfall accumulation forecast at phl.

The record is 12" as checked by ray kruzdlo of our office.

March 13-14, 1993. #9 is 8.8 inches march 3-4, march 4-5 in

Allentown record march two day storm total snow 19.9 inches
march 19-20 1958 (close to a 60 year anniversary). # 10 is the
10.2" event of 3 29-30 1970. We have a very good chance of top
10 at abe, barring any last minute model surprises.

Wilmington record march two day storm total snow is 17.9 inches
3 19-20 1958. # 10 is 7.9" 3 2-3 1960. We have a good chance of
cracking top 10 list.

Atlantic city record march two day storm total is 11.6 inches
3 1-2 69 and #7 is 7 inches 3 4-5 15 and 3 6-7 53. There is a
chance of cracking top 10.

We'll update again at 5 pm Wednesday once we know whats occurred
and whats coming.

Also from rutgers-dave robinson and mat gerbish at our request

Since we think northern nj per the rutgers areal definition will
exceed 5 inches of snow (areal average), probably end up closer
to 15 inches or more... This would put northern nj by Thursday
morning 8 am as the highest ever in our recorded history. Right
now the average is 18.9 there and we expect it to rise to ~25 or
30" by 8am Thursday (this has yet to happen), which would
propel us to the snowiest march on record in nnj.

The monthly march record for a single station in nj to our
knowledge via rutgers is 43.0 in march 1958 at canistear
reservoir. Oak ridge had 42.0 and greenwood lake 36.8 also in

This storm may drive the current jefferson township and rockaway
values which are near 33 inches, above those records... We just
dont know yet but by this time! We'll let the reality determine
the outcome.

This is all stated to place some perspective on what we think
this upcoming event can produce for us.

The information on this web site has not been checked for accuracy. It is for entertainment purposes only and should be independently verified before using for any other reason. There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
