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

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 Carolinas. The Euro has two over central CONUS while
hinting at low pressure off the coast of the Carolinas. 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.
