Area Forecast Discussion

250 PM EDT Tue Jun 3 2025

.SYNOPSIS...
High pressure will remain anchored offshore through early Thursday.
A cold front will approach the area later on Thursday and Friday,
before tracking across the Mid-Atlantic region on Saturday. High
pressure will briefly build in later on Sunday. A warm front will
approach the forecast area on Tuesday.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
Analyzed 1024mb high pressure centered over the Mid Atlantic
states early this afternoon will move eastward through
Wednesday and be centered about 200 miles east of the Virginia
and North Carolina coast by late Wednesday. No rain is forecast
through the period and subsidence will inhibit any afternoon
clouds to form. The elevated smoke and haze will continue on
Wednesday and impacts at the surface should remain minimal.

Max temperatures Wednesday will peak in the 80s, with readings
in the 70s along the coast and in higher elevations.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/...
High pressure will remain offshore of the Mid-Atlantic region
Wednesday night before beginning to shift well out to sea on
Thursday. Dry weather is expected Wednesday night and much of
Thursday.

As a cold front approaches and stalls to our north and west later
Thursday and Thursday night, we could see some isolated to scattered
showers and possibly a thunderstorm, mainly across northeast PA and
northwest NJ.

The cold front will inch closer on Friday. As a result, we`re
expecting more showers to track into the forecast area, possibly down
to the 95. PWAT values will start creeping up across the region too,
topping out between 1.25-1.75 inches. As a result, there will be
potential for a heavy shower or downpour.

Temperatures will run above normal through the period. Overnight
lows will mainly be in the 60s. We`ve tamped down Thursday`s
afternoon highs a bit due to cloud cover. Still, we`re looking at
upper 70s to upper 80s for highs Thursday and Friday.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
By Saturday, the cold front will begin to move across the area,
and lead to increasing chances of precipitation. There is some
instability forecast with CAPE values of 500-1000 J/kg, and PW
values increase to 1.5-2.0 inches. So there will be the
potential for thunderstorms and brief heavy downpours. Mid level
winds are forecast to be fairly weak, 40-50 knots or less, so
shear is not expected to be overly strong. However, there could
be a few isolated strong storms.

The front is forecast to stall to our south Sunday as high pressure
builds to our north, possibly leading to dry conditions later Sunday
into Sunday night.

On Monday and Tuesday, said front will inch north as a warm front.
Showers and Thunderstorms will pop again as a result. Lows will
mainly be in the 60s. Highs will be in the 70s to lower 80s.
