therefore extend the Wind Advisory until 7 am Sunday. For the
rest of the region, the Wind Advisory expired at midnight.
Otherwise, Arctic high pressure continues to build into the
Great Lakes and Ohio Valley, with low pressure over the western
Atlantic intensifying and deepening. A tight northwest pressure
gradient over the Northeast and Mid-Atlantic remains, but is
gradually relaxing as the low pulls away. Wind gusts have
decreased to 30-50 mph areawide, but will remain elevated into
the overnight hours.
The strong winds and very cold daytime temperatures will result
in wind chills below zero during the daytime hours today,
ranging from around -5 to -15 degrees for most areas, and as low
as -25 in the southern Poconos.
Temperatures tonight will drop into the single digits by Sunday
morning for most of the region and as low as -5 degrees in the
southern Poconos and far northwest New Jersey. Wind chills will
be as low as -30 degrees tonight in the southern Poconos and far
northwest New Jersey. Minimum wind chills will range from -10
to -20 for the rest of the region tonight. The Extreme Cold
Warning remains in effect for the entire region through noon
Sunday. High temperatures Sunday will range from the mid 10s to
low 20s, but northwest winds will be 10 to 20 mph with gusts up
to 30 mph and this will result in maximum daytime wind chills in
the single digits Sunday afternoon. Lows Sunday night will be
in the single digits, and wind chills will be below zero; as low
as -10 degrees north and west of the Fall Line and as low as
-15 degrees in the southern Poconos. A Cold Weather Advisory
will likely be needed through Monday morning following the
ending of the Extreme Cold Warning.
A slow moderation of temperatures will occur as the new week
progresses.
KEY MESSAGE 2...Temperatures moderating closer to normal during
upcoming week, with a weak system possibly impacting the region mid-
week.
High pressure will dominate early in the coming week, and with
heights building aloft as a ridge slowly migrates east and the
high shifting east off the coast, temps should see some
substantial moderation, at least compared to current values.
Highs will approach freezing in many areas on Monday, then
likely pass freezing in many areas Tuesday, and possibly touch
40, especially in southern locales, on Wednesday. Lows will stay
mostly in the teens Monday night and may not get much, if at
all, below freezing Tuesday night thanks to the southwest flow
ahead of an approaching cold front.
Said front will cross the region sometime Wednesday into
Wednesday evening as low pressure passes north. Guidance has
grown decidedly dry with this system, so while we can't rule out
some precip with it yet, odds are starting to turn against it.
Kept some slight chance POPs around. Temps turn cooler again
behind said cold front, but not nearly to the magnitude of the
current outbreak...highs Thursday, Friday and Saturday, while
staying a bit below normal, appear likely to break the freezing
mark in most areas. Lows will stay below, which will keep the
melt down slow. POPS increase at week's end as guidance remains
all over the place with any potential systems for next weekend.

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Early this morning...VFR. NW winds 15 to 20 kt with 25 to 35 kt
gusts, diminishing a bit after 09Z. High confidence.
Today...VFR. NW winds 15 to 20 kt with 25 to 35 kt gusts,
diminishing to 10 to 15 kt with 20 to 25 kt gusts after 21Z.
High confidence.
Tonight...VFR. NW winds 10 to 15 kt with gusts up to 20 kt,
diminishing to 5 to 10 kt after 03Z. High confidence.
Monday...VFR. NW winds 5 to 10 kt. High confidence.
Outlook...
Monday night through Thursday...VFR most likely prevails.
&&
.MARINE...
Northwest winds of 20 to 30 kt with gusts up to 45 kt are
expected across much of our coastal waters into the overnight
hours. The Storm Warning for NJ Atlantic Coastal Waters south of
Manasquan Inlet and the Delaware Bay has been cancelled and
replaced with a Gale Warning, which is in effect through 10 AM
Sunday. Heavy Freezing Spray Warnings are also in effect through
Sunday morning.
Small Craft Advisories will be needed Sunday- Sunday night as
winds decrease further. Freezing Spray Advisories will also be
needed in this period.
Regarding the river/bay ice...Ice continues across area bay
waters and inland estuaries. This includes, but is not limited
to the Delaware estuary. On rivers, the ice has grown in
thickness enough to cause some restrictions in the flow. Per
satellite imagery and ice analysis data, the Delaware River is
mostly ice covered from the entrance to Delaware Bay northward,
or upstream, to at least Washington Crossing.
The most common ways river ice can break up is either through a
thermal or mechanical means. We would like to see temperatures
rise into the 40s for a few days, but that's not expected within
the next several days. Significant rainfall, producing river
rises, can also break up ice. But again, that's not in the
forecast either this coming week.
As a result, ice will continue to expand before it contracts,
especially with another deep freeze expected this weekend. For
next week, there may be a pause in the growth during the
daylight hours as temperatures warm above freezing, however
temperatures at night will continue to support expansion.
Outlook...
Monday through Tuesday...mainly sub-SCA conditions expected.
Wednesday through Thursday...Marginal SCA conditions more
likely.
