through tonight with continued clear skies and SW winds.
Gustiness inland will diminish with loss of heating this
evening. Ample cooling tonight allows lows to reach the mid 40s
across most of the area and upper 40s to low 50s in coastal
areas with light westerly winds to start the day.-- End Changed Discussion --

.SHORT TERM /THURSDAY/...
-- Changed Discussion --
As of 4 PM Wed...Dry cold front enters the northern tier in the
morning. After frontal passage, winds shift northerly at 5 to
15 kts by noon. Weak cold air advection and increasing cloud
coverage associated with the front will limit highs in the north
to the mid to upper 50s while the clearer southern areas will
reach the low to mid 60s.-- End Changed Discussion --

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
As of 3 AM Wed...Unsettled weather returns Friday as a series
of lows will move along a stationary boundary, increasing
chances of rain through the weekend and into next week.
Thursday night...Dry conditions continue Thursday night with
increasing cloud cover through the night. Overnight lows are
expected to drop into the mid/upper 30s inland and low 40s along
the coast.
Friday through Saturday night...The cold front that pushed through
Thursday will be stalled across the Deep South Friday as high
pressure continues to dominate the area briefly. As the day
progresses on Friday, a coastal trough will develop Friday night as
a wave of low pressure lifts along the stalled frontal boundary,
meanwhile a shortwave moves aloft. Though there can be iso to widely
sct showers Friday afternoon, but the best chances for widespread
rain will be Friday night into Saturday. The weak low is forecast to
lift Saturday with rain diminishing by the afternoon. Expect
temperatures to be in the 50s Friday, then a warm up on Saturday
with highs in the upper 60s away from the beaches.
Sunday and early next week...Another cold front approaches the area
Sunday with a series of lows moving along the boundary as it
progresses eastward, leading to a wet period--though timing is
uncertain, but trends continues. The frontal boundary is forecast to
push through Monday night with lingering showers Tuesday.
