.SHORT TERM...
(Today and tonight)
Issued at 230 AM CDT Wed May 29 2024

Main area of severe convection pushed east of the area late
yesterday evening, but new more scattered showers and storms will
continue to work its way in from the northwest through sunrise.
Other than the one severe storm that wont die south of Lubbock,
none of the rest of the convection appears particularly strong.
Based on radar trends, will bump POPs up for the 09Z-12Z and
12Z-15Z time frames this morning across the Big Country and keep
an eye on continued trends.

Rain chances for the remainder of the day are uncertain. Air mass
will again be unstable with CAPE values above 3000 J/kg but shear
aloft isn`t as strong as it has been in recent days, there is a
little more cap to fight through, and surface boundaries are more
diffuse. CAMs are not showing a lot of coverage, but given the air
mass, will opt to go with a mention of scattered storms across
most of the area. Suspect that once we get into daylight, a couple
leftover outflow boundaries will end up reappearing and may
provide a little more focus

For tonight, will bump POPs up across the northern Big Country a
little more. CAMs continue to show a weak shortwave passing
across the area and helping kick off a little more convection
along the Red River north into Oklahoma. Models have struggled
with timing of these little waves so uncertainty that this
convective cluster will actually develop, but worth a little
higher thunderstorm chances than areas farther south.

.LONG TERM...
(Thursday through Tuesday)
Issued at 258 AM CDT Wed May 29 2024

Shower and thunderstorm chances will continue through the weekend,
with the higher chances generally concentrated across the Big
Country. With weak ridging in place on Thursday multiple
shortwaves embedded in the westerly flow will move overhead.
Models hint at another round of storms developing across the
Panhandle down into the Permian Basin Thursday afternoon, with
this activity potentially developing into an MCS and and moving
eastward into the Big Country Thursday evening/night. SPC has
a slight risk for severe weather on Thursday mainly north of I-20
to account for this scenario. Large hail and damaging winds would
be the primary hazards especially if an MCS does develop. Could
see a lull in activity on Friday before yet another shortwave
trough initiates another round of thunderstorms Saturday
afternoon/night and possibly more scattered storms on Sunday.
Upper level ridge over northern Mexico builds back in on Monday
and Tuesday resulting in only a slight chance of isolated showers
and thunderstorms on Monday. Temperatures will be much cooler for
the rest of the week- mainly in the 80s and 90s- before warming
back up near the triple digits by the beginning of next week.

.AVIATION...
(12Z TAFS)
Issued at 609 AM CDT Wed May 29 2024

Cluster of showers and storms moving across the Big Country around
the KABI location and will include a TSTM mention up there. May
see some additional storm development just about anywhere across
the West Central Texas terminals this afternoon and evening but
given the uncertainty in timing and coverage, will leave out for
now. Patchy MVFR cigs this morning but mostly low end VFR
conditions are prevailing, with the expectation that all sites
are VFR by mid to late morning and continue that through the
evening hours. Will start to bring MVFR cigs back into the area
after midnight.
