Synopsis
High pressure off the mid-atlantic coast will continue to move
offshore today. An area of low pressure will move northeast from the
great lakes into quebec through Thursday. A warm front will cross
the region today and tonight, followed by a cold front Thursday.

High pressure will then build into the region Friday and Saturday. A
developing area of low pressure to our northwest will drag a cold
front through the region Sunday, with a coastal low potentially
developing along this front early next week.

Near term through tonight
The big concern in the forecast today lies with the freezing
rain drizzle potential across the northern portion of the cwa. The
nam has a stronger signal for this to occur, whereas the GFS is a
bit warmer drier. Not overly confident of what will end up
transpiring. The large-scale lift associated with a subtle midlevel
perturbation moving through the region during the day is weak, at
best, and there are some questions as to how quickly the low levels
will moisten sufficiently for any precipitation to occur. Bufkit
soundings are quite variable model to model, and the overall
appearance of the more aggressive models is for (near-)saturation
generally at below the 700-mb level. This suggests any precipitation
will be light and liquid. Would not be surprised if little more than
drizzle occurs northwest of the fall line through the day given the
shallow look of the moist profiles and the rather dry near-surface
layer. Of course, the other question will be surface temperatures,
with statistical guidance appearing much too warm much too quickly.

The typically colder NAM (raw) model output was favored here, which
slows the warming temperatures north of i-78 considerably during the
day. So far, this has worked well for temperatures early this
morning in these areas (especially the poconos and far northern new
jersey).

With the above in mind, have slight chance for (light) freezing rain
starting late this morning. It doesn't appear that this will make it
further south than the lehigh valley at this point, as surface temps
will likely be above freezing by the onset of precipitation
southeast of the fall line. The window for near-freezing
temperatures in the lehigh valley is quite short, with temperatures
well above freezing likely by mid afternoon. The best potential for
a longer duration of near-freezing temperatures remains in carbon
and monroe counties, where a winter weather advisory is already in
effect. Confidence is too low for expansion elsewhere given
questions regarding precipitation coverage, onset versus marginal
(and warming) surface temperatures, and overall model variability.

Tonight the main forecast question is how quickly the steadier rain
moves into the area, with overall consensus suggesting a slower
onset. Generally, increased pops from northwest to southeast through
the period, with timing matching a consensus hi-res blend. The main
period of precipitation looks to start after midnight, possibly
reaching the atlantic coast as late as daybreak.

Kept temps on the colder side for today's highs, given the cold air
over the past couple days, and the overall tendency for it to stick
around in these scenarios longer than simulated. Also, bumped temps
up a touch across DELMARVA to account for the stronger warm air
advection trend through the day. As it stands, highs should range
from the mid 30s across the poconos to the low 50s across southern
delaware. Winds will pick up through the day, with gusts above 25
knots possible along the coast and over DELMARVA by evening. Given
the southerly flow and warm air advection, lows Wednesday night will
likely not deviate much from Wednesday's highs, with a warming trend
possible through the period.

Another sensible weather impact of note tonight will be the
increasing south to southeast winds generally southeast of the urban
corridor. Winds may gust 30 to 35 mph in this area (possibly
stronger near the coast) as a strong low-level jet develops aloft.

Though mixing will not be efficient, it may be strong enough to
generate some rather breezy conditions overnight.

Short term Thursday through Thursday night
Strong surface low in quebec 12z Thursday will lift northeast
through the day, dragging a cold front through the region. Very
strong southerly southwesterly low-level flow in advance of the
front will continue to advect warm and unusually moist air into the
area. Forecast pws approach 1.5 inches during the morning, which is
in record territory climatologically. Additionally, very strong and
deep ascent aided by favorable positioning of the right entrance
region of an intense 250-mb jet streak, considerable differential
cyclonic vorticity advection, and low-level isentropic ascent aided
by a 70-kt synoptically-forced low=level jet will generate
widespread precipitation across the mid-atlantic during the morning.

Bufkit soundings show very weak instability in advance of the front,
so little or no lightning is expected (except maybe off the coast).

Nevertheless, strong frontal lift appears to generate sufficient
lift for locally intense enhanced precipitation. With the high-
octane air in place, a period of heavy rain is probable in advance
of the front. Model QPF is generally 1 to 1.5 inches from 09z to 21z
across the area, with most of this precipitation likely occurring in
a 3-6 hour period at any particular location. With cold soils,
months of antecedent wet conditions, and relatively high rain rates
expected at times during the day, flooding potential seems elevated.

Have issued a flood watch for the lehigh valley southeastward to the
i-95 295 corridors for Thursday. Though the watch is technically an
areal flood watch, flash flood potential exists here, given the
possibility of high rain rates producing quick rises in sensitive
streams and urban areas. For more information, see the hydrology
section below.

Winds will also be elevated in advance of the front, aided by the
aforementioned low-level jet and sufficient mixing. Additionally,
any convectively-induced precipitation may mix down some very strong
winds aloft. Will need to watch this potential closely as the event
unfolds.

The front races offshore during the afternoon, with precipitation
potential rapidly lowering behind it. Cold air will filter in
quickly. Depending on how quickly the precipitation ceases upstream
of the front, may see a quick brief switchover to snow showers
before the precipitation ends, especially in the northwest cwa.

Temperatures will surge in advance of the front, with readings in
the 50s to near 60 southeast of the fall line. However, temperatures
will fall rapidly behind the front, with lows below freezing
virtually everywhere Thursday night. Skies should rapidly clear by
Thursday night, although some lingering moisture may keep the low
clouds present in the far northwestern cwa. Cannot rule out a few
flurries here as low-level northwest flow develops and a weak
perturbation approaches the northern mid-atlantic overnight.

Long term Friday through Tuesday
Following the system, mainly dry but colder conditions move back in
for Friday lasting through Saturday as the next high moves in.

Temperatures will be slightly below average, but still an
improvement to what we have seen the past couple days.

Lots of uncertainty in this period. In the big picture, a long wave
trough will remain present over eastern north america with a closed
low at 500 mb persisting around hudson bay. The pattern looks to
remain active with several potent pieces of energy moving
southward eastward around this trough towards the coast, potentially
phasing with southern stream energy. An area of low pressure looks
to develop across the great lakes as several of these pockets of
energy associated with shortwave troughs phase by Sunday. This keeps
precipitation in the forecast through the weekend and into the
middle part of next week. This will start as snow showers across the
poconos and likely build southeast across the CWA Sunday. The chance
for snow and rain showers could last really through the middle part
of next week. Still considerable uncertainty in how much moisture
will be available and how things will come together. Kept a slight
chance of rain showers (south) and snow showers (north) in the
forecast through Wednesday. Temperatures remain cold with highs
slightly below average through the beginning of the week. Wednesday
looks to be quite chilly with highs remaining below freezing across
much of the forecast area. &&

Aviation 09z Wednesday through Sunday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Rest of tonight...VFR with light south winds. High confidence.

Wednesday... GenerallyVFR, though CIGS will be lowering and may
reach sub-vfr thresholds northwest of philly by mid to late
afternoon. Cannot rule out some drizzle or showers at rdg abe as
well. Winds generally south around 10 kts. Llws increases from the
southwest rapidly this afternoon. Moderate confidence.

Wednesday night... Conditions will be deteriorating gradually to sub-
vfr and may reach ifr or worse near after midnight. Rain chances
increase from northwest to southeast, especially after midnight.

Winds south around 10 to 15 kts, possibly gusty near southeast of
phl. Southwesterly llws anticipated through the night. Moderate
confidence.

Thursday... Cig vsby restrictions will continue through at least
early afternoon, with rain (heavy at times). Southwesterly llws will
also continue through the morning. Conditions are expected to
improve rapidly during the afternoon, withVFR possible late.

Southwest winds 10 to 20 kts with higher gusts before frontal
passage, becoming northwest afterward. Moderate confidence.

Thursday night... MainlyVFR with west to northwest winds around or
below 10 kts. Moderate confidence.

Outlook...

Friday and Saturday... MainlyVFR conditions expected. Winds
generally below 20 knots. High confidence.

Saturday night through Sunday night... Cold front may bring rain
and or snow showers, thus possibly lowering visibilities and
bringing restrictions, especially at krdg and kabe. Moderate
confidence.

Marine
Sub-advisory conditions exist on the waters at this time, but south
to southwest winds are already increasing off the new jersey coast.

Winds are expected to reach advisory levels later this morning, so
have moved up the start time of the small craft advisory to 6 am on
the atlantic waters. Conditions should remain sub-advisory on
delaware bay through the day.

Conditions will deteriorate further tonight, as south to southwest
winds strengthen to 20 to 25 kts with gusts to at least 30 kts.

Gales cannot be ruled out, especially on the atlantic waters, though
low-level temperature profiles are not climatologically favorable
for their development. As such, did not issue a gale watch at this
time. Conditions will worsen on delaware bay, and the small craft
advisory remains in effect overnight.

Seas on the atlantic will increase to 5 to 10 feet tonight.

Outlook...

Thursday: small craft advisory in effect, and gales are possible.

Seas 5 to 10+ feet. A cold front moves through during the afternoon,
with winds switching from south or southwest to northwest. Rain
likely, with visibility restrictions probable. Cannot rule out
thunder, but confidence was not high enough to include in the
forecast.

Thursday night: rain moves out, and northwest winds diminish but
will likely remain above advisory criteria much of the night. Seas
will also remain elevated but will lower as the night progresses.

Small craft advisory was extended through 4 am Friday for delaware
bay and through 6 am for the atlantic waters.

Friday and Saturday... Sub-sca conditions expected with westerly
winds 10-15 knots. Seas from 4-6 feet.

Saturday night through Sunday night... Sub-sca conditions
expected with easterly winds initially, turning southwesterly
from 10-15 knots. Seas from 3-5 feet.

Hydrology
We have issued a flood watch for late tonight through Thursday
afternoon from the lehigh valley and northwest new jersey
southeastward to the i-95 295 corridors. A cold front will move
through the area on Thursday, with a round of rain, moderate to
heavy at times, expected to move through the region in advance of
the front late tonight into tomorrow morning. Expected storm totals
are generally from 1 to 1.5 inches, with locally higher amounts
possible. Normally, these totals would not be forecast to produce
much flooding. However, a number of factors suggest an elevated
threat exists...

1) antecedent wet conditions, including from the rainfall this past
weekend.

2) relatively cold soils, aided by the arctic air that spread across
the region the past couple of days.

3) the expectation of most of this rain occurring in a three-to-six
hour period. With higher rain rates expected during a portion of the
event, especially just in advance of the frontal passage on
Thursday, additional runoff will be generated, which could lead to
flooding of particularly sensitive spots (e.G., urban areas and
quickly-responding creeks and streams).

4) light to moderate rain occurring for a few hours before the
heaviest rainfall occurs, which may act to saturate soils
sufficiently for efficient runoff during the most intense rainfall.

An isolated instance of flash flooding is possible, especially if
the heaviest rainfall (and high rainfall rates) occurs along the
urban corridor or atop smaller stream creek basins that respond
rapidly to runoff.

River flooding cannot be ruled out, especially on the passaic and
millstone rivers, if the axis of heaviest rainfall intersects the
associated basins.

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.
