.SYNOPSIS...
Issued at 252 AM EST Thu Feb 9 2023
Rain will gradually taper off later this morning with windy
conditions expected from late morning through the afternoon.
Primarily dry and mild weather returns Friday through early next
week. There are additional chances for rain during the middle of
&&
.SHORT TERM...(Today and Tonight)
Issued at 252 AM EST Thu Feb 9 2023
Morning water vapor shows robust midlevel vort max currently lifting
through Missouri with an impressive satellite presentation.
Associated surge of warm/moist air advection on the nose of a 60 kt
LLJ is currently moving into our area. Peak rainfall rates will be
now through 12Z. As the warm front continues to lift north and
midlevel dry slot moves overhead later this morning precip will
become lighter and more scattered. Primary impact continues to be
the expected wind later today. Strong surge of isentropic descent
behind occluded front...coupled with tight gradient and decent
mixing will bring the potential for high winds during the afternoon.
Profiles appear too stable for any meaningful convection but a few
showers are possible along the passing front and may enhance
downward momentum transfer as suggested in Marginal SWODY1. Slight
eastward adjustment to surface low track has introduced some
uncertainty in N/NW extent of highest synoptic wind gusts. Forecast
soundings indicate a slightly more stable environment along with a
slightly weaker gradient, particularly in the NW. Warnings/
advisories are already out and still think our far SE could see a
few 50kt gusts (esp with any showers) so no changes planned to
headlines at this time but final wind gusts may come in a touch
lower than previously expected. May still be a few 40kt gusts in the
00-02Z timeframe but wind gusts should drop quickly in the evening
and no changes to current headline timing planned.
Sharply cyclonic flow could maintain a few light showers in our NW
through the afternoon and evening but expect a general drying trend
overnight. Lows dip near freezing but anticipate dry conditions
by the time this colder air arrives.
&&
.LONG TERM...(Thursday through Tuesday)
Issued at 252 AM EST Thu Feb 9 2023
A secondary, northern stream shortwave crosses the Great Lakes on
Friday. Moisture/instability are very limited in our area and best
CVA forcing looks to pass just north of our CWA. Did however
maintain some slight chance PoP's in our northern zones for Fri
morning given some possibility for an isolated sprinkle or flurry.
No accumulation anticipated though. Sprawling high pressure builds
over the region late Fri and persists through the weekend. Initially
cooler (still slightly above average, though) temps on Sat will
moderate for Sun with an overall sunny and pleasant weekend
anticipated.
Another shortwave/weak cold front crosses on Monday with little
fanfare. Held with dry NBM initialization given poor forcing and
limited moisture. Much better chances for rain arrive Tue night as
the first in a pair of southwest CONUS upper lows eject NE. The
second arrives Thu night. The first appears highly sheared and
overall unimpressive but worth a round of light rain. The second one
may be a bit stronger and could possibly tap into some colder air
but it is very difficult to discuss any specifics at this time
range. Overall story for most of next week appears to be mild
conditions with some periods of light rain in predominately WSW
flow aloft.

.AVIATION...(For the 12Z TAFS through 12Z Friday Morning)
Issued at 639 AM EST Thu Feb 9 2023
Southern edge of large area of rain was nearly clear of KFWA with
IFR cigs/vsbys likely to improve to low end MVFR for a few hours
prior to the arrival of the initial front. Although IFR
conditions may start out at 12Z, should improve quickly so left
out of TAF. A few showers will be possible prior to its arrival.
At KSBN, LIFR cigs likely to hold on until the arrival of the
front. Timing updated for both locations.
Focus will then be on narrow line of showers on the front and
winds behind it with gusts of 20 to 35 kts common and a few even
reaching/exceeding 50 kts (mainly with the line itself). Behind
this line period of high end MVFR to VFR conditions appear likely
with best chance for VFR at KFWA. This should persist into the
afternoon before the cold front moves in, bringing lower clouds
back in to stay and a quick shift to the west or northwest for
winds. No significant changes made to this period.
