Synopsis
Low pressure over the mid-atlantic lifts along the coast this
evening. It then passes east of new jersey and towards the gulf
of maine by Thursday morning before finally departing late in
the day. High pressure builds in from the north and west to
close out the work week, then moves offshore on Saturday. Low
pressure lifts through the region over the weekend, followed by
high pressure for the start of the new week.

Near term until 6 am Thursday morning
Changes with this forecast: have cancelled the winter weather
advisory for sussex and kent co in de, and queen anne's, talbot,
and caroline counties in md. The winter storm warning from
cecil and kent co in md has been extended through 00z. Though
they may not get much additional snow, temperatures will stay
below freezing for the next few hours, so light freezing rain
and sleet is possible.

The lull of relatively light precipitation continues. As of 3
pm, we had reports of mixing as far north as burlington and
ocean counties in nj. For areas generally near and south of
dover, de, temperatures are above freezing and precipitation is
mostly rain. The changeover to a wintry mix will continue to go
further north. The change over to rain will likely come 2 to 4
hours after the change over to mix.

Snow and ice amounts: new snow amounts of up to 2 inches (on
top of what has already fallen so far today) is possible. The
bigger concern going forward will be ice amounts, which could be
as much as a tenth of an inch for berks county, and possibly
some locations in the lehigh valley.

Impacts: with the changeover occuring over the next few hours
for several locations, the evening commute has the potential to
be very hazardous as ice on top of snow could result in very
slippery conditions. Please allow extra time to reach your
destination, and reduce speed. Roads that appear wet could be
icy.

Short term 6 am Thursday morning through 6 pm Thursday
No major changes with the forecast on Thursday, we are
expecting quieter weather. The last of any rain will be ending
Thursday morning along a weak cold front behind the main low in
delmarva. Clouds should be clearing through the day. Breezy
conditions are also possible behind the cold front, with gusts
of 20 to 25 mph possible. Highs will range from the mid 40s over
the southern poconos to the low to mid 50s for areas near and
s E of the i-95 corridor.

Long term Thursday night through Wednesday
High pressure over the midwest will move into the great lakes
on Friday, then moves into northern new york state Friday night
before moving offshore on Saturday. Meanwhile, h5 trough over
the southern rockies will eject into the southern plains, and
surface low pressure develops out ahead of that trough near the
lower mississippi valley. On Saturday, the primary low lifts
into the great lakes as a secondary low forms over the mid-
atlantic. This new low passes east of new jersey and towards
cape cod Saturday night, then lifts towards the canadian
maritimes on Sunday.

Temperatures will be at or just above normal for the end of the
week and into the start of the weekend, and with no significant
arctic air in place, not expecting much in the way of ptype
issues overall. However, if precip begins early Saturday
morning, there could be a brief period of a wintry mix at the
onset, as temperatures should be below freezing Friday night. By
late Saturday morning, temperatures rise above freezing, and
will remain warm through the precip.

Abundant surface moisture will stream into the northeast and
mid-atlantic, and pwats will be upwards of 1.5". Could have
periods of moderate to locally heavy rain, mainly Saturday
night, with the passage of the low.

Conditions dry out on Sunday afternoon, then a tight westerly
pressure gradient develops with gusty winds possible.

On Monday, surface high pressure builds in from the west, and a
tight northwest pressure gradient develops Monday afternoon
between the high and the departing low. Although it will be dry,
the main story on Monday will be the potential for strong and
damaging winds. Winds at about 500 mb will be around 125 kt, and
a strong LLJ of 55-65 kt with good mixing up to 850 mb. Although
it is a bit far out, this does indicate the potential for
damaging winds Monday afternoon. For now, will carry NW winds
20-30 mph with 30-50 mph gusts, and mention the potential for
gusts as high as 60 mph in the hwo.

High pressure will spread east through the middle of next week.

There is the potential for another storm during the mid-week
period.

After an unseasonably warm Sunday with highs in the 60s,
possibly approaching 70 in parts of delmarva, temperatures
return to at or just below seasonal levels Monday through
wedensday.

Aviation 21z Wednesday through Monday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Rest of this afternoon... Ifr or near-ifr with snow and mixed
precip across the most terminals. Precip will change to all rain
kmiv, kacy and kilg by early evening. East to southeast winds 5
to 10 knots.

Tonight... Ifr across most terminals most of the time. Mixed
precip across the northern terminals will change to rain later
this evening. Areas of fog expected. Mostly light E SE winds
most of the night. Vsbys somewhat variable in steady rains and
fog. Mostly 1-2sm.

Thursday... Ifr MVFR early then improvement back toVFR as drier
air arrives. Change back toVFR mostly 13 14z for the western
terminals and 15 17z for kacy kmiv.

Outlook...

winds 10 kt or less, becoming NE around 5 kt Friday night.

Saturday through Sunday... Sub-vfr conditions in brief wintry
mix Saturday morning, then rain. SE winds less than 10 kt,

Marine
Winds and seas will continue to increase, with small craft

On the delaware bay, winds and waves should stay below sca
criteria.

Outlook...

Thursday night... Marginal SCA conditions possible.

restrictions in rain and possible fog.

Sunday... Winds become west 20-30 kt with 35-40 kt gusts.

Monday... Nw winds 25-30 kt with 35-50 kt gusts possible.

Tides coastal flooding
With onshore flow tonight through Thursday morning, water
levels will run a bit high around the high tide Thursday
morning. Winds shift to the west after sunrise, and this should
help mitigate water levels from rising to advisory thresholds.

Tide levels may run from 1 2 foot to as much as 1 foot above
normal during the high tides Thursday morning, and a few spots,
mainly along the atlantic coast, may briefly touch advisory
thresholds. Will not issue a coastal flood advisory at this time
for Thursday morning, as it will not be widespread.

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.
