.DISCUSSION...
KEY MESSAGE 1...A cold front passes through the region later
this morning. Conditions improve this afternoon.

Low pressure tracking across central Canada will first pull a
warm front through the region early this morning, and then a
cold front passes through the region later this morning. Ahead
of this front, showers and scattered thunderstorms are moving
through southeast Pennsylvania and into New Jersey, while some
additional showers are moving through Delmarva and southern New
Jersey. While there is a good deal of CIN over the area, the
first wave of showers and scattered thunderstorms are moving
into an area with MUCAPE upwards of 1500 J/kg. So these storms
may bubble up a bit, especially with some 40 kt of 0-6 km Bulk
Shear. While organized severe weather is unlikely, cannot rule
out an isolated severe thunderstorm or 2 going into daybreak.

Cold front then passes through the region late this morning. A
drier airmass spreads into the region with surface dewpoints
dropping from the upper 60s to around 70 to the low 60. Skies
clear out this afternoon as high pressure builds in from the
west.


KEY MESSAGE 2...Fair weather is expected to return later Sunday
and should persist into the middle of the upcoming week.

More zonal flow with some subtle ridging moves in for the first
half of the week. At the surface, high pressure will mainly be
in control, resulting in dry and tranquil weather through
Wednesday. Temperatures should be seasonable through this
stretch.

mph in the afternoon. Breaking waves will be 1 to 2 feet with
light southerly swells with a 6 to 8 second period. As a result,
there is a LOW risk for the development of dangerous and life
threatening rip currents at the Jersey Shore and at Delaware
Beaches.
