Area Forecast Discussion

.SYNOPSIS...
An areas of low pressure moves eastward across Virginia and Delmarva
tonight into tomorrow morning. A cold front passes across the region
by Tuesday evening. Much warmer and drier weather dominated by high
pressure will settle over the area Wednesday through Friday. A cold
front may approach the area from the north by early next weekend.


&&

.NEAR TERM /THROUGH MONDAY/...
The front stalled to our south across southeastern Virginia remains
nearly stationary. Meanwhile, a new area of low pressure continues
to develop across the Ohio River Valley, while to our north, high
pressure is centered over Quebec. Over the near term forecast
period, conditions will remain quite similar to present as a stable
easterly flow is maintained across our area with the high to our
north and the developing low pushing to our south as it moves
eastward toward Virginia. Showers and isolated thunderstorms will
continue to develop to the north of the front throughout much of the
afternoon and evening. Deeper surface-based convection will remain
south of the front, which should stay well south and west of our
region.

Showers and isolated thunderstorms will gradually taper off with
time by later this evening into the overnight hours tonight as
surface ridging builds in from the north and east. It will remain
mostly cloudy with a continuing east to northeast flow and lows
mainly in the upper 50s to low 60s. The cloud deck will be quite low
with the continuing marine influence and there could also be some
patchy fog and drizzle around.

Little change is expected as we head into the day Monday. The center
of the high will have progressed to the east to the Canadian
Maritimes but will remain extended over the area with a continuing
onshore flow and associated marine stratus deck as a result. This
will keep it mostly cloudy with highs once again in the low to mid
70s. While no significant rainfall is expected there may continue to
be some spotty light showers and patchy drizzle around.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
The weather gets a bit more active again Monday night into Tuesday
as a cold front approaches from the west Monday night and moves
through the area on Tuesday. This will bring another round of
showers and storms through the area...especially overnight Monday
night into the first part of Tuesday. Guidance continues to trend a
bit faster with the front, which would have most of the rain out by
the early to mid-evening. This all said, the instability will be
low, which should limit the threat for severe thunderstorms and
heavy downpours. SPC has a Marginal Risk (1/5) for severe weather,
which makes sense given both instability and shear are meager, but
given relatively strong forcing, cannot rule out a strong to severe
thunderstorm. Main threat would be damaging wind gusts. QPF amounts
during this period should generally range from 0.25-0.75".

Lows Monday night should generally be in the upper 50s to low 60s
with highs Tuesday generally ranging from the mid 70s to low 80s.
Tuesday night should see similar if not slightly cooler overnight
lows compared to Monday night as skies start to clear out.


&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
High pressure builds in for Wednesday and Thursday bringing sunshine
with dry weather. Temperatures look to get above normal for the end
of the week. Highs Wednesday look to be mainly in the low to mid 80s
with highs for Thursday and Friday reaching the upper 80s to near 90
for many areas-potentially the first 90 degree day of the year for
Philadelphia (first one usually comes in May). Humidity levels will
be low Wednesday before starting to creep up a bit on Thursday and
especially Friday.

As we get into next weekend, a cold front will start to push
southward towards the area bringing a return to chances of showers
and thunderstorms. At this point the best chance of precipitation
looks to be Saturday as there may be an area of low pressure that
develops along the front as it may tend to stall near the area,
leading to an unsettled weekend. Temperatures for the weekend cool
to more seasonable or perhaps even below normal levels.
