127 PM EDT Mon Aug 30 2021
.SYNOPSIS...
Tropical cyclone Ida will continue to weaken while moving
northeast from Mississippi toward West Virginia on Tuesday and
Wednesday, bringing periods of heavy rain and gusty wind.
Continental high pressure is expected to settle into the region
later in the week with mostly sunny skies and near to slightly below
normal temperatures.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 1040 AM Monday: 12Z RAOBs show capped atmos remains in place
despite the expected weakening of the upper ridge as mentioned
below. Even the CAMs have backed off on convective coverage over the
mountains this afternoon and evening as forecast soundings show the
cap lingering even over the mountains. Have backed off as well but
not removed entirely as they are the most likely location to see any
diurnal convection.
Upper anticyclone centered just southeast of the CWA this morning
will gradually drift southeast and weaken through the period, as
height falls associated with Hurricane Ida gather some speed in
lifting from the lower Miss Valley toward the TN Valley through the
period. Temps will again be around 5 degrees above normal.
Spotty high terrain convection could linger through the evening,
while weakening outer bands associated with the approach of T.C. Ida
could make a run for far western areas by sunrise Tuesday. 20-40
PoPs will therefore be featured for much of the tonight period
across the mountains.
&&
.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
As of 345 AM EDT Monday: Tropical cyclone Ida is still expected to
become post-tropical while accelerating through the Tennessee Valley
into the Central Appalachians Tuesday afternoon into Wednesday.
Guidance has continued to slowly trend closer to the forecast area.
This combined with increased high resolution guidance supports an
uptick in expected rainfall intensity and amounts with generally one
to locally three inches of rain expected, except three to five
inches and locally higher for south facing escarpment and southwest
mountains. The Weather Prediction Center has upgraded the slight
risk of excessive rainfall to a moderate for areas with higher
rainfall amounts. We may eventually need a Flash Flood Watch for
some of these areas. Deep tropical moisture and forcing as well as a
period of about six hours of favorable orographic enhancement will
support periods of heavy rain is expected to begin as early as
Tuesday afternoon across the Southwest mountains and become more
widespread into Tuesday night before gradually tapering off from
southwest to northeast Wednesday.
The closer proximity of Ida also ups the ante for gusty southerly
winds late Tuesday into early Wednesday focused across the ridgetops
and also possibly the French Broad River Valley given its roughly
south to north orientation. Wind gusts of 30 to 40 mph will be
possible along the ridge tops thanks to a 40 kt jet at 850 mb with
gusts of 20 to 30 mph in play for the French Broad Valley and in
heavier showers or thunderstorms outside of the mountains. This
combined with heavy rainfall may support some downed trees or power
lines where higher gusts occur.
Lastly, there is a low end risk of isolated weak and brief tornadoes
given the highly sheared enviroment. Model soundings still indicate
mid-level capping and resultant low end instability, which is the
main factor limiting this threat. It's a bit too earlier too
highlight any given area within the forecast area as the timing is
still a bit too far out late Tuesday into the overnight.
The widespread rain and clouds will temper the tropical airmass with
daytime highs cooling to near 80 for most Wednesday and overnight
lows near 70.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 145 AM EDT Monday: The extended period Thursday into this
weekend will provide well deserved quiet weather. The remnants of
Ida will continue to be absorbed into the mid-latitude westerlies,
effectively energizing a long wave trough as it pushes off of New
England Thursday into Friday. A continental air mass building in on
the heals off the departing trough will provide much drier
conditions with any lingering showers mainly confined to the
northern mountains coming to an end by Thursday evening. Surface
high pressure will settle into the area by the weekend with light
winds and clear skies providing good radiational cooling conditions
at night and the first taste of fall just in time for meteorological
fall (which starts September 1st) with lows in the 50s mountain
valleys to around 60 east of the mountains. Nearly full sun and
increasing heights thanks to an elongated ridge building in from the
west will still support highs mainly in the 80s, except possibly
returning to low 90s east of the mountains by Sunday. Even still
only slowly rebounding dewpoints will take an edge off the building
heat compared to what we've experienced as of late.
&&
.AVIATION /18Z MONDAY THROUGH SATURDAY/...
At KCLT and elsewhere: Upper level high pressure and the suppressed,
relatively dry air mass remains over the area into the evening. In
fact, cumulus was slower to develop than the past several days.
Latest CAMs have backed off on convective chances over the
mountains. There is convection off to our NW and this may move in
before sunset, but chance to low for even the KAVL TAF. Cumulus
dissipates this evening but mid and high clouds will spread over
the area. Think this will limit mountain valley fog and have kept
KAVL at MVFR for now. SW wind this afternoon becomes light
overnight. Low VFR does move in during the day Tuesday as the
remnants of Tropical Cyclone Ida move into TN. Precip chances
increase through the day, but timing has limited PROB30 mention to
the most likely locations. Gusty S to SW winds will also develop
during the day.
Outlook: Periods of rain/restrictions and some gusty winds can be
expected Wednesday as the remnants of Ida move by to our north.
Drying follows for the latter part of the week.
