Synopsis
Arctic high pressure across the middle atlantic region this morning
will move offshore by tonight. Low pressure will move into the great
lakes region Wednesday and then down the saint lawrence valley
Thursday. Its associated fronts will cross the area tonight and
Thursday. High pressure will return for Friday and Saturday. A cold
front will cross the area Sunday. Next week, a coastal system may
affect the area later Monday and Tuesday.

Near term until 6 pm this evening
600 am update: wind chill advisory allowed to expire for carbon
and monroe counties, as winds have diminished in most of the
area. The exception is the ridgetops, where wind chills are
still running around -15 degrees. Winds should diminish quickly
the rest of the morning here as well, and given the areal
coverage is quite small and readings are becoming more marginal,
see no need to extend the advisory for a couple more hours.

Interestingly, a stream of low clouds and even some flurries has
reached mount pocono early this morning, but this will be
short-lived with any precipitation non-measurable. Added some
flurries and increased sky cover here for a couple hours.

Previous discussion...

high pressure of arctic origins is approaching the area early this
morning, and winds are beginning to diminish as the pressure
gradient slackens. The ridge will move over the region today, and
winds will continue to diminish and gradually become more westerly
(or even variable). Skies should be mostly sunny today, although
some increasing high clouds may occur by or during the afternoon as
a jet streak remains overhead and warm advection begins to spread
into the region.

Main forecast challenge is temperatures today, with statistical mos
exhibiting a little spread. Mav is somewhat lower than met ecs in
general, which is rather unusual (at least lately). Given the lack
of mixing and the very cold origins of the high, I am inclined to
side with the colder guidance somewhat. Highs should be warmer today
as midlevel ridging increases and warm advection commences by
afternoon. Current forecast has temperatures mainly in the 20s
across the area, with low 30s near the coast and in central southern
delmarva.

Short term 6 pm this evening through 6 am Wednesday
The surface high will move offshore tonight, with a midlevel ridge
axis moving through the region during the overnight hours. A potent
vort MAX will be be moving through the central plains, with several
smaller perturbations ejecting from the main trough into the ohio
valley and downstream. Warm advection will increase overnight, which
will act to continue the increasing cloudiness and to stunt diurnal
cooling, particularly overnight as the cloud cover begins to
thicken lower and surface winds become predominantly southerly.

However, the temperature forecast is quite tricky tonight, because
winds will be light during the evening, and cloud cover may be too
thin and too high to prevent a sharp nocturnal drop during the
evening. Consider the MOS guidance for millville: 13 from the mav,
17 from the met, and 24 from the ecs. Results will be highly
sensitive to the above-mentioned factors, with locally large errors
probable as meso- to microscale effects combat the larger-scale
evolution. In general, went on the cold side of guidance and
especially so in the susceptible pine barrens and valley locations
northwest of philadelphia. Confidence is rather low, since the
timing of increased cloud cover is quite uncertain. Forecast lows
are generally in the teens outside of the urban corridor and the
immediate coast, with temperatures around 20 or even in the lower
20s in delmarva.

Precipitation associated with the central u.S. Trough and ejecting
perturbations should remain well north and west of the area through
the night.

Long term Wednesday through Monday
On Wednesday, the next storm will be moving into the area. The
recent trends are pointing a slower moving system, so the pops have
been lowered in Wed somewhat. The warming trend will have more time
to take hold, so the threat for significant amounts of sleet or
freezing rain seem to be lessening with time. Still, we do have
marginal temperatures Wed morning across the southern poconos and
adjacent areas S of that. For that reason, we have not eliminated
the chc for some sleet and freezing rain from the grids yet.

Elsewhere, pops steadily increase thru the day with occasional rain
wed afternoon and into thu. Precipitation totals will be 1 to 2
inches across the region.

High pressure will build back across the area late Fri and into
Saturday, so a dry fcst is continued. It will get cold again Fri sat
with readings below normal, but not the arctic chill of the past few
days. Highs Fri Sat in the upper 20s to low 30s across the delaware
valley and some 5 to 10 degrees cooler across the southern poconos
and north nj.

Model agreement begins to become a factor later this weekend with
some indicating a cold front and some showers Sunday and other not.

We have just continued with chc pops for the northern areas for now
and kept slgt chc pops elsewhere. Temperatures will favor snow N w
and rain across the delaware valley and S e.

Next week, the operational models become all over the place with
regards to various systems affecting the region. The 00z cmc was
trending like the 12z ec with a coastal system coming near our
waters next tue, but then the 00z ec came in without this low.

The GFS has a front crossing the area next Tue with a weak wave
forming SW of our area then moving thru Tue night with (probably)
snow. The ec and cmc don't have this at all. So the rather high
amounts of uncertainty will lead me to keep some slgt chc pops
for the Mon Tue periods for now. Temperatures should remain a
few degrees below normal.

Aviation 12z Tuesday through Saturday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Today...VFR with northwest winds around 10 kts becoming light
and variable during the afternoon. High confidence.

Tonight...VFR with increasing mid and high clouds. Winds generally
light but may become predominantly southerly. Moderate confidence.

Outlook...

wed thru thu... Lower CIGS and vsbys with rain and fog. Ifr lifr
possible. Gusty winds and llws possible Thu morning.

Thu night... Improving conditions. Few showers psbl. Patchy fog.

Fri thru sat... MostlyVFR expected.

Marine
700 am update: freezing spray advisory allowed to expire for
upper delaware bay but extended for lower delaware bay and the
adjacent atlantic waters of delaware until 10 am based on
surface observations from lewes. Small craft advisory allowed to
expire for delaware bay, as winds have diminished below
criteria. Finally, the low water advisory for upper delaware bay
has expired, as low tide has passed.

500 am update: gales are winding down across delaware bay and
the atlantic waters. The gale warning has been converted to a
small craft advisory through 7 am for delaware bay and through
10 am for the atlantic waters. Winds and seas should
diminish lower below criteria thereafter. Wind direction will
switch fairly quickly this afternoon to a southerly or
southeasterly direction, with speeds increasing tonight. Winds
may approach advisory criteria late tonight, but will hold off
on issuing a small craft advisory until the current products are
dropped and confidence with the onset timing of the next round
of stronger winds increases.

Freezing spray continues at this time on delaware bay and on the
atlantic waters, though the trend has been slowly downward
overnight. Decided to continue the freezing spray advisory through
12z for delaware bay and the delaware atlantic waters and through
15z for the new jersey atlantic waters based on latest observations
and model forecasts.

Low tide has passed for the atlantic coast, and blowout tides
have ended. The low water advisory for lower delaware bay and
the atlantic waters was allowed to expire at 5 am. However, low
tide is still occurring on upper delaware bay and will occur on
the tidal delaware river later this morning. Blowout tides are
expected in these areas, per latest observations from ship john
shoal and delaware city. The low water advisory continues until
7 am for upper delaware bay, and a special weather statement
addressing the threat for the tidal delaware river has been
issued.

The next low tide will occur during the afternoon, but it looks
as if the combination of slackening winds and increased time
from the full moon will prevent a third round of widespread
blowouts. However, some models (e.G., estofs; stevens institute
ensembles) come quite close. We will continue to monitor.

Outlook...

wed thru thu... SCA conditions expected. Rain and fog.

Thu night thru Fri night... SCA expected on the ocean and mostly
sub-sca on delaware bay. Fair.

Sat Sat night... Sub-sca. Fair.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... Small craft advisory until 10 am est this morning for
anz450>455.

Freezing spray advisory until 10 am est this morning for
