.SHORT TERM...
(This evening through Tuesday)
Issued at 220 PM CDT Mon May 8 2023

Hi-res guidance has continued on a downward trend for severe storm
activity across the area this afternoon and evening. While storms
are still expected to form off of the dryline later this afternoon,
weak winds through the entire profile will limit storm scale
organization. SPC downgraded our Slight Risk from overnight to a
Marginal Risk as instances of large hail and damaging winds will
still be possible, especially during the initial phases of storm
development. Storms that fire this afternoon will linger into the
early/mid evening before the boundary layer re-stabilizes and storms
quickly dissipate. We'll begin to see some upper level clouds
move into the area, especially down in our southeastern counties.
Winds out of the south will stay in the 10-20 mph range overnight,
keeping the lower levels well mixed lending to mild overnight lows
in the mid 60s once again.

Weak upper level ridging will set up across the West Central Texas
area tomorrow. Upper level clouds across our southeastern zones will
keep temperatures down there slightly cooler in the upper 80s with
areas further north and west warming into the low to mid 90s once
again. Southeast winds will continue to funnel low level moisture
into the area. While daytime heating is expected to erode the
capping inversion, guidance has greatly diminished our chances for
seeing storms. A weak dryline is expected to be well off to our west
across the Permian Basin and Trans Pecos region. Activity may form
off of this boundary but ascent overall is expected to be weak and
the latest CAMs have struggled with convective initiation tomorrow,
especially for areas further east of the dryline. Instability is
also forecast to be much lower than we've seen over the past few
days with CAPE values less than 1000 J/kg. Any threat for severe
weather would likely come more in the form of damaging winds as
these storms will be elevated. Overall, have decided to decrease
PoPs to slight chance across the area with confidence waining in
their potential.

&&

.LONG TERM...
(Tuesday night through next Sunday)
Issued at 220 PM CDT Mon May 8 2023

The active weather is expected to continue through the rest of the
week.

Wednesday and Thursday, we will continue to deal with a sloshing
dryline, and the potential for afternoon and evening thunderstorms
developing, generally across the western half of our area, and
progressing northeastward. Although the area hasn't been outline in
any severe weather outlooks, the possibility for some of these
storms to become strong to severe will be there, with the main
hazards being large hail and damaging winds. Temperatures will
remain warm through Friday with highs in the mid 80s to lower 90s
each day.

From Friday into the weekend, long range models have come into
pretty good agreement about the evolution of a broad upper level low
developing across the southwestern U. S., and northern Mexico. Along
with this low, a weak cold front is expected to make its way into
Texas, stalling near or in west central Texas from Friday night
through the weekend. This combination is favorable for repeated
rounds of convection over the area, with some periods of heavy rain
embedded in the storms as well. Although there is still uncertainty
with this potential event, confidence is growing that the area will
see significant rainfall amounts from late Friday through Sunday.

.AVIATION...
(00Z TAFS)
Issued at 649 PM CDT Mon May 8 2023

Isolated to widely scattered convection is occurring early this
evening. KABI stands the best chance to see TS on station and
will have a TEMPO group through 02Z. Otherwise, will keep VCTS
at most of the other sites through mid evening. Some stratus may
develop across the far southern terminals after 10Z tomorrow
morning. May see some MVFR ceilings at KBBd, KJCT and KSOA but
confidence too low to include a ceiling at this time.
