AREA FORECAST DISCUSSION
National Weather Service Mount Holly NJ
630 PM EST Thu Feb 21 2019
Weather Synopsis:
A weak cold front was dropping across the area this evening.
High pressure will build in from the north and west to close
out the work week, before moving offshore on Saturday. Low
pressure lifts across the Great Lakes over the weekend and its
associated fronts will affect our area. More high pressure will
build in for the beginning of next week.
Near Term:
UNTIL 6 AM FRIDAY MORNING -
Weak cold front should continue to settle south through our
region this evening, as a broad surface high builds towards our
region. The main thing of note with the front is that some
precipitation will be possible along the front by late tonight
(when it is just south of our region). Rain could build into
northern Delmarva, so have increased PoPs there, but the rest of
the region should see dry conditions.
Despite the cold front, expect temperatures to be slightly
above normal, with lows from the mid 20s to upper 30s across the
region.
Short Term:
6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY -
As the high continues to build closer to the region, fair and
seasonable weather is expected through the day on Friday.
Temperatures are expected to be near normal, with highs from the
mid 30s to mid 40s (slightly lower than Thursday thanks to the
weak cold front). Pressure gradient is expected to decrease, and
consequently winds should be decreasing as well.
Long Term:
FRIDAY NIGHT THROUGH THURSDAY -
Fri night/Saturday...Mostly fair thru this period with
increasing clouds. There is a chance for some light rain to
arrive across Delmarva and SE PA by Saturday afternoon. A cold
night Friday night with near normal high temperatures expected
Saturday.
Saturday night/Sunday...A wet period with deep low pressure
cutting well to the west and a series of fronts to cross our
region. Steady rains Saturday night becoming showery Sunday.
Overall, around an inch of rain could occur. Some hydro concerns
possible with recent rains/snows and still rather wet ground.
Winds will be moderate thru Sunday morning , then a cold front
will cross the area and winds will increase over the Middle
Atlantic area. High temperatures Sunday before the front crosses
will be in the 50s across the north and low/mid 60s over the
Delaware Valley and Delmarva.
Sunday night through Monday night..Precipitation ending but
windy and much colder. Highs Monday will be 15 to 20 degrees
below Sundays` readings. Sub-freezing temperatures are expected
for Monday night as high pressure builds over the area.
Tuesday thru Thursday...No major weather systems foreseen, but
a sharpening H5 trough across the Great Lakes could send a few
weak clipper systems over the area. A little snow could occur,
but the details are too low confid to include anything more than
a chc pop in the present fcst.
