.DISCUSSION...

KEY MESSAGE 1...Precipitation chances return on Wednesday and
linger through the end of the week.

A weak, dry cold front crossing the region earlier this morning is
now bringing in a much drier airmass. Mostly sunny skies this
afternoon with breezy conditions (gusts around 20-30 mph). Winds
quickly subside this evening as high pressure builds in from the
north. Seasonable temperatures expected this weekend as highs reach
the 60s and lows in the 40s each day.

Surface high pressure moves offshore at the start of next week,
though dry conditions are maintained through at least Tuesday. A
decaying shortwave trough aloft is now forecast to pass to our
south, with likely not even a few showers in the forecast now.
Temperatures moderate in response to the east to southeast flow with
highs forecast in the upper 60s to lower 70s Monday and Tuesday.

The weather pattern becomes more active beginning midweek as a deep
upper trough approaches from the west. Global guidance shows a range
of solutions with the commonality being multiple cut-off lows. The
GFS has two located over central CONUS tracking along the trough.
The Canadian has one over central CONUS and another off the coast of
the Carolina`s. The Euro has two over central CONUS while hinting at
low pressure off the coast of the Carolina`s. Either way, an active
weather pattern is expected as the trough tracks eastward through
the end of next week.  Precipitation chances increase on Wednesday
with widespread rain likely on Thursday into Thursday night.

High temperatures will be in the upper 60s to low 70s east of the
Blue Ridge with those along and west in the upper 50s to 60s.
Overnight low temperatures will be in the 50s each night.
