.DISCUSSION...
KEY MESSAGE 1...Low pressure passes north of the area tonight and
drags a cold front through the region on Friday.

High pressure is southeast of the Canadian Maritimes and continues
to drift out to sea. Southwest winds increase later today as the
pressure gradient tightens between the offshore high and a cold
front approaching from the west. Warm air advection will be underway
today, and highs will top off in the low to mid 70s. These highs are
some 15 to 20 degrees above normal. Skies will be partly to mostly
sunny, but clouds will increase late in the day as that front draws
nearer.

Low pressure passes north of the area tonight, and this will pull a
cold front south through the region. Showers develop this evening,
and continue through tonight. The front will be through most of the
region by Friday morning, then will become nearly stationary over
the Delmarva Peninsula most of the day before finally sagging
towards the Mid-Atlantic late in the day. Showers taper off over the
southern Poconos, northern New Jersey, and the Lehigh Valley in the
morning, and then showers continue over southern New Jersey, the
Delaware Valley, and Delmarva most of the day. Some elevated this
evening may result in a rumble of thunder or two this evening, but
severe weather is not expected.

Temperatures drop during the day Friday as cold air advection will
be underway. Temperatures will be in the mid to upper 50s for most
of the area and in the low to mid 60s in the morning, and will fall
into upper 40s to low 50s through the afternoon.


KEY MESSAGE 2...Mild and unsettled pattern takes hold as early as
Monday Night next week.

High pressure that dominates this weekend resulting in dry and quiet
weather will move offshore on Sunday. Return flow sets up, ushering
in a warmer airmass after below normal temperatures on Saturday, and
near normal temperatures on Sunday. Warm south/southwesterly flow
for the beginning and middle part of next week will result in a
stretch of above normal temperatures for the early and middle
portion of next week.

While it will be on the more mild and warmer side next week, there
will be multiple chances for rain as several frontal systems slide
by. None of these systems look overly impactful at this point, but
there could be some periods of rain, beginning late Monday and
continuing off and on through the middle of the week.
