.SYNOPSIS...
Dry and cool high pressure will persist over the region trough
the week with below normal temperatures expected through mid-week.
Temperatures will warm to near normal by late week.
&&
.NEAR TERM /THROUGH TUESDAY/...
As of 720 PM EDT Monday: A cool and dry sfc high remains centered
over New England as the southern periphery of the sfc ridge extends
down into the Southeast through the period. Aloft, troughing will
remain overhead. Cirrus coverage will periodically increase at times
while streaming overhead through tomorrow. Some stratocu may return
on Tuesday, mainly across the mountains. Expect low-end NE wind
gusts to return outside of the mountains Tuesday morning as mixing
taps the northeasterly low level jet over the area. Speeds should be
lower than what we saw earlier today thanks to a weaker pressure
gradient. Lows tonight will end up around 10 degrees below normal,
with temps dipping into the 30s across the higher ridges in the NC
mountains. Highs on Tuesday will end up around 10 degrees below
normal.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 1:25 PM EDT Monday: The short-term forecast picks up at 00z
on Wednesday with the large-scale upper level pattern gradually
amplifying again as broad upper trofing digs down over Ontario and
Quebec and upper ridging amplifying over the central CONUS. At the
sfc, broad high pressure will be centered well to our NE but still
be in control of the synoptic pattern across most of the eastern
CONUS. Over the next couple of days, a weak sfc low will develop
within the baroclinic zone just off the SE Coast and track north-
ward. The low is expected to be moving out over the north Atlantic
by the end of the period late Thurs. The latest guidance continues
to keep any deeper moisture associated with this system to our east.
As for the sensible fcst, not much has changed. We should remain dry
with temperatures warming each day but still remaining a few degrees
below normal for mid-September.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 1:05 PM EDT Monday: The extended fcst picks up at 00z on
Friday with upper trofing centered to our north as stout upper
ridging persists to our west over the central CONUS. Over the
next few days, the upper ridge tries to spread over our area
from the west, yet most of the long-range guidance has some
amount of upper trofing lingering along the Eastern Seaboard
and to our north. At the sfc, broad high pressure will get
reinforced from the north as the period begins late Thursday.
Over the next few days, the center of the high will migrate
SE and eventually off the coast of Nova Scotia on Sunday.
Nonetheless, we are expected to remain under its influence
thru the period with little chance for precip. Temperatures
are expected to start out just below climatology on Friday
and then warm to just above climo by the end of the period
next Monday.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
At KCLT and elsewhere: Dry with periodic VFR FEW to SCT cirrus at
times through the 00Z TAF period. Wind gust timing will once again
be the trickiest part of the forecast. Wind gusts have tapered off
across the terminals as of 00Z but low-end gusts should return
Tuesday morning across the SC Upstate terminals and at KCLT. Gusts
are not expected at KAVL or KHKY through the period but a rogue
intermittent gust cannot be entirely ruled out, mainly at KHKY.
Gusts should taper off by the early Tuesday afternoon. Wind
direction will remain NE east of the mountains. Winds at KAVL will
be light and VRB this evening into daybreak Tuesday before toggling
more E/ESE by mid-morning Tuesday.
Outlook: VFR and dry into the weekend. Fog and/or low stratus is
possible each morning, especially in the mountain valleys.
