.SHORT TERM... /NEW/
/Tonight through Sunday Morning/

Showers and isolated storms via warm air advection remain ongoing
this evening ahead of our main event to our west. The broken
lines of storms along the Pacific front/dryline will continue to
grow upscale into a more singular line as the negatively tilted
trough detaches and forms a closed upper low. The line of storms
is progged to breach our western counties within the next hour.
Our greatest severe threat will be when the line first enters our
CWA to around the US-281 corridor as mid-level lapse rates and
instability are at their highest (with regards to RAP analysis).
Severe storms capable of large hail and damaging winds will be
possible. As the line continues towards the I-35 corridor, severe
storms will continue to be possible, though instability will be on
the downward slide. The line will blow through the I-35 corridor
between 11PM-1AM.

Another concern with the line of showers and storms is the
potential for flooding for areas east of I-35. With present moist
soils, additional most likely rainfall accumulations of 1-1.5"
will increase the flooding threat overnight into tomorrow morning
for low-lying and flood-prone areas. Elsewhere (generally west of
I-35), expect less than an inch of rainfall. The line will
finally exit the region near daybreak.

A much quieter forecast is in store for the weekend. Saturday
afternoon will feature highs in the 60s. Cloud cover will begin
to clear out throughout the day on Saturday from W to E, however
wrap-around moisture from the lagging upper low will usher in
additional cloud cover into Sunday morning. Sunday morning lows
will bottom out in the 40s region-wide.

.LONG TERM... /Issued 213 PM CST Fri Feb 2 2024/
/Saturday Night Through Next Friday/

By Sunday morning, the elongated center of a deep upper level low
will continue sliding beneath a broad upper ridge/high located
over the upper Midwest and Great Lakes. This upper low will slowly
advance southeastward towards the Gulf Coast on Sunday as upper
level ridging builds into the Desert Southwest. Though most
locations will enjoy some dry time Saturday afternoon and night,
low level moisture lingering north and east of the surface low's
center will wrap around and move back into our northeastern zones
Sunday, bringing additional low rain chances to these areas as the
low shifts slowly overhead.

The tight pressure gradient wrapping around the southwestern
flank of the departing surface low will allow gusty west-northwest
winds to spread across the state overnight into early Sunday.
These winds are expected to reach our western and southwestern
zones just before daybreak Sunday and peak through the early
afternoon. Though sustained wind speeds of 20-25 mph and gusts up
to 35 mph will be possible in a few locations in Central Texas,
the spatial coverage of these conditions is too limited to warrant
the issuance of a Wind Advisory at this time.

Breezy north-northwest winds will prevail through Monday
afternoon, when surface high pressure should finally begin
building across the region. By Tuesday evening, the surface high
will slide east of the FWD forecast area allowing onshore flow to
return. Dry conditions will prevail through mid week with daytime
temperatures creeping back up into the mid 60s. Ridging aloft will
eventually give way to an upper trough advancing eastward from
the Pacific coast. Afternoon highs in some areas will reach the
lower 70s Thursday afternoon as surface winds veer to the
southwest in response to pressure falls in the lee of the Rockies.
There will likely be a few opportunities for precipitation
beginning Thursday and continuing through the end of the current
forecast period (and beyond) as this progressive pattern brings a
series of shortwave troughs across the central/southern Plains.

.AVIATION... /NEW/
/00Z TAFs/

Abysmal flying conditions are expected to continue through
tomorrow morning.

Scattered showers and isolated thunderstorms will continue across
the TAF sites this evening in advance of the main line of showers
and storms. While some see-sawing of cigs has occurred, prevailing
MVFR cigs will continue through this evening at all TAF sites
alongside southerly winds. The line of storms will move through
D10 and ACT between ~05-08Z, with rain lingering until around
10Z. As the line passes, winds will shift westerly, then return
to southerly through the end of the period. Expect MVFR cigs to
persist through the morning hours, but conditions will steadily
improve back to VFR by afternoon.
