Synopsis
Low pressure rapidly intensifies off the mid atlantic coast
this evening then races out to sea by Sunday morning. High
pressure briefly builds across the area again on Sunday, then
offshore Sunday night. A strong warm front lifts northward
across our area later Monday into early Tuesday, followed by a
cold front late Wednesday. The cold front stalls to our south by
next Thursday with a series of waves moving north and east
along it late next week into early next weekend.

Near term until 6 am Sunday morning
We are getting total snow reports up to 6 inches across parts of
eastern pa and northern nj (see latest pnsphi product) and snow
continues to fall over those areas. Therefore we have upgraded
to a winter storm warning there. Radar mosaic loop indicates
snow starting to taper off for berks co and vicinity, but
moderate to heavy snow should continue farther east for a couple
more hours.

Previous discussion below:
clouds will continue to thicken and lower and precipitation
will overspread our region from the west and southwest during
the late afternoon and early evening hours. Temperatures are
such that the precipitation should begin as snow in the poconos
and in far northern new jersey. It is expected to begin as a
brief period of rain in extreme northeastern maryland, northern
delaware, southeastern pennsylvania, and much of northern and
central new jersey before changing to snow. An all rain event is
anticipated for southeastern maryland, southern delaware and
much of southern new jersey.

Mid level short wave energy moving up the ohio river valley
this afternoon will enhance precipitation rates this evening. A
relatively brief period of moderate to heavy snow is expected
with amounts in much of eastern pennsylvania, far northeastern
maryland, northern delaware and central and northern new jersey
ranging from 2 to 5 inches. The far upper delmarva, extreme
southeastern pennsylvania and the southern part of central new
jersey should favor the low end of those values.

The guidance has trended a bit warmer with the system than in
previous runs. As we get into the late evening hours, the
rain snow line may advance well into the philadelphia
metropolitan area and central new jersey. We will indicate a
change to rain before the precipitation ends. The rain will cut
into snowfall amounts in parts of those areas.

Due to the expected location of the rain snow line, our lowest
area of confidence in our snowfall forecast extends from the
upper DELMARVA and extreme southeastern pennsylvania into parts
of southern and central new jersey.

A mid level short wave trough located over iowa and vicinity
this afternoon will progress to the east and it should pass
overhead late tonight. The feature will kick the last of the
precipitation out to sea. It appears as though most of the rain
and snow in our region will end by 2 or 3 o'clock in the
morning.

The wind is forecast to be from varying directions at less than
10 mph for much of the night, becoming northwest at 10 to 15
mph toward morning. Low temperatures are anticipated to range
from the middle 20s in the poconos to the middle 30s in southern
delaware.

Short term 6 am Sunday morning through 6 pm Sunday
High pressure is forecast to build into our region from the
west for Sunday. We are anticipating a mostly sunny day with a
northwest to west wind around 10 mph.

Sunday afternoon is expected to become relatively mild. Highs
are forecast to be in the lower and middle 40s in the poconos,
the lehigh valley and northern new jersey. Readings should get
into the upper 40s and lower 50s in northeastern maryland,
delaware, southeastern pennsylvania, and southern and central
new jersey. Much of the new snow cover should melt by day's end.

Long term Sunday night through Saturday
**record warmth possible Tue and expected wed**
Sunday night through Wednesday... .

To start the period Sunday evening, high pressure crests over
the area in the evening before slowly moving east overnight.

This will set up good conditions for radiational cooling due to
light winds and mainly clear skies despite the airmass not being
all that cold. Lows by Monday morning should generally be in
the 20s to low 30s.

For Monday, the high continues to push off to the east through
the day with a warm front approaching from the south and west
ahead of the next system. This will bring increasing clouds with
some showers likely by afternoon... Mainly over eastern pa.

Highs will generally range from the mid 40s north to the 50s
across the DELMARVA and southern nj.

Some showers may continue into Monday evening before lifting
out overnight as the front moves through. Temperatures will be
quite mild with lows only dropping to the 40s to low 50s. This
will be followed by near record warmth on Tuesday as a strong sw
flow takes hold. We continue to forecast temperatures above the
model consensus and are generally looking at highs ranging from
the 60s in the north to the low 70s across SE pa as well as
much of the DELMARVA and southern nj. Areas right near the coast
will likely be cooler though.

For Tuesday night into Wednesday, temperatures continue to warm
with record warmth forecast by Wednesday... Highs currently
forecast to reach the low to mid 70s over SE pa as well as much
of the DELMARVA and nj. Conditions should be dry for the most
part though by late Wednesday a cold front could bring some
showers in from the west... Mainly for eastern pa.

Wednesday night through Saturday...

in the big picture, this period will be dominated by somewhat
cooler, though still well above average temperatures as a long
wave trough persists over the rocky mountains with the area in a
sw flow. Conditions will also trend more unsettled as a series
of waves move north and east along a wavering front that will
linger in the region.

For Wednesday night into Thursday, the aformentioned cold front
with some associated rain showers pushes south through the area
before stalling over the mid atlantic. Forecast guidance then
indicates a wave trying to move north along the front though
there is uncertainty in how this all evolves as high pressure
will also be building in to our north. The high could suppress
precip mainly to our south into Thursday but again, these
details are uncertain so we keep chances for showers in the
forecast through Thursday. Beyond this time there may be a brief
break before a stronger low pressure system moves north along
the front by later Friday into next Saturday. Highs Thursday and
Friday will generally be in the 40s and 50s with 60s possible
again by next Saturday.

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

Through 0600z... Conditions becoming ifr early this evening in
snow at krdg, kabe, kttn, kpne, kphl and kilg. Accumulating snow
is expected at the airfields (up around 4 inches at krdg, kabe
and kttn, and up around 2 or 3 inches at kilg, kphl and kpne). A
mix or change to rain is expected at kilg, kphl and kpne late
this evening before the precipitation ends. Conditions lowering
to ifr in rain at kmiv and kacy this evening. East to southeast
wind around 5 to 10 knots.

Late tonight (0600z-1200z)... Precipitation ending from
southwest to northeast with conditions gradually improving to
vfr. Wind become northwest 10 to 15 knots with gusts around 20
knots.

Sunday...VFR. Mostly clear with a northwest wind around 10
knots.

Outlook...

Sunday night...VFR. Confidence: well above average.

Monday...VFR early, lowering to MVFR or ifr during the
afternoon or evening with rain. South to southwest wind.

Confidence: above average.

Monday night... MVFR ifr conditions continue with rain possible
in the evening, and low clouds dense fog possible overnight.

Confidence: above average.

Tuesday... MVFR ifr conditions possible through midday in low
clouds fog. Conditions improving toVFR during the afternoon.

Southwest winds may gust around 20-25 knots in the afternoon.

Confidence: average.

Tuesday night...VFR early, then possibly lowering to MVFR ifr
as low clouds fog may develop overnight. Confidence: average.

Wednesday... MVFR ifr conditions possible early with low
clouds fog. Conditions improving toVFR during the day. Chance
of showers late in the day. Southwest winds may gust around
20-25 knots. Confidence: average.

Wednesday night through Thursday... Chance of showers with
associated restrictions. Confidence: below average.

Marine
Low pressure will pass off the virginia capes this evening
before moving quickly out to sea. A gusty northwest wind is
expected to develop on the coastal waters of new jersey and
delaware in the wake of the low. As a result, we will issue a
small craft advisory for our ocean waters and for delaware bay.

It will be in effect from 4:00 am until 11:00 am Sunday. The
wind is forecast to diminish gradually on Sunday afternoon.

Outlook...

Sunday night through Monday... Sub small craft advisory south
winds. Confidence: well above average.

Monday night... Sub small craft advisory conditions expected,
although southwest winds may gust around 20 knots. Confidence:
above average.

Tuesday-Wednesday... Winds should stay below advisory levels,
but seas may increase to near 5 feet. Confidence: average.

Wednesday night - Thursday... Winds should stay below SCA levels
with seas persisting in the 3 to 5 foot range.

Climate
Record high temperatures could be challenged on Tuesday,
february 20th and probably will be equaled or exceeded Wednesday
february 21st. These records are listed below.

we are not posting the monthly records at this time since our
forecast is 3 to 7 degrees below the monthly record. We'll check
again Sunday and Monday to see if our forecast edges warmer.

The following are the record warm mins for Wednesday feb 21.

Barring a sudden immediate cool down behind the cool front at
1159pm Wednesday, there is a good chance of record warm daily
minimum temperatures as well the previously referenced record
highs.

atlantic city rainfall already ranks 11th wettest in february
history with 6.50" in 2010 the wettest. By sunrise Sunday,
atlantic city should rank about 8th wettest in its historical
database.

The february average temp for phl projects 41.0 or 5.3f above
normal or 8th warmest on record. This placement can change
anywhere from 3rd to 12th depending on a 1 degree change in the
eventual average. Bottom line... We're likely on our way to a top
10 warmest february on record. The warmest was last year with a
44.2f average. Years 2002 and 2012 flank our currently
projected 8th warmest.
