...A significant severe weather event is possible across the central
and southern Plains states this afternoon and evening...

The latest severe weather/mesoanalysis analysis shows a dryline
from Slaton to Midland to just west of Sanderson, moving slowly
east. Also, meso sector 2 satellite imagery already indicates a
few CI fails over Sterling and Coke counties. To the east of the
dryline, there is extreme instability across much of our area,
SBCAPES of 5000 to 6000 J/kg and rich low level moisture,
dewpoints in the 70s, even upper 70s over the eastern Big Country.
Also, effective shear values are 50 to 60 knots and the shear
vector is perpendicular to the dryline, so that means separated
storms and probably supercells to start with this afternoon.

Looks like coverage of storms will remain isolated and most areas
will remain dry. An isolated storm or two will probably develop by 3
PM due to low level convergence along the dryline or a local breach
in the cap. The potential for this will along and east of a
Sweetwater to San Angelo line, with maybe better coverage in the SPC
Enhanced Risk Area. Any storms that develop will rapidly become
severe due to the extreme instability and strong vertical wind
shear with the main hazards being giant size hail(baseball size),
damaging winds and tornadoes due to low level shear improving
during the late afternoon and early evening. Keep up with the
latest weather information and have multiple ways of getting
warnings and watches! Most Hi-Res models indicate storms moving
east of the area by 10 PM. However, a few models have isolated
storm or two until 1 AM. Going with low chance Pops and severe
wording across the Concho Valley, Big Country and Heartland early
this evening. Going with a dry forecast after 10 PM through the
rest of the short term. Expect hot and dry weather Sunday with
highs in the upper 90s to around 103.

.LONG TERM...
(Sunday night through next Saturday)
Issued at 116 PM CDT Sat May 25 2024

....Unsettled Pattern to Return Next Week...

Hot weather will continue for Memorial Day as an upper- level
ridge persists over northern Mexico. Numerical guidance suggests
yet another day of triple-digit heat with low overall rain
chances.

Starting Tuesday, the pattern looks to become unsettled again as an
upper-level trough becomes established over the eastern US and puts
the southern Plains into northwest flow.  Models show multiple
shortwave impulses aloft riding over the north edge of the weakening
ridge through Friday.  Warm temperatures in the low to mid 90s will
be expected each afternoon with plenty of Gulf moisture in place due
to southeast surface flow.  A cold front should also dip into west
central Texas late Monday night into Tuesday and stall through
Wednesday. Thunderstorms should develop along both the front and the
dryline late Tuesday with lingering convection possible Wednesday.
The front should lift back northward on Thursday and provide even
more chances for showers and thunderstorms through Friday.
Conditions through the entire week are likely to be warm and muggy.
However, local conditions may be impacted at times by cloud cover
and cold pools left from earlier convection.

.AVIATION...
(18Z TAFS)
Issued at 1207 PM CDT Sat May 25 2024

Expect isolated thunderstorms across much of the area mainly
between 21Z and 04Z. A few storms may still linger until 07Z
indicated by a few Hi Res models. Some storms may be severe. For
now, will keep the VCTS at the KABI terminal for a few hours and
will watch radar trends for possible amendments at the remaining
terminals. Otherwise, expect VFR conditions and gusty south winds
at times.

This Hazardous Weather Outlook is for portions of west central
Texas.

.DAY ONE...This Afternoon and Tonight

Strong to severe thunderstorms will again be possible across
portions of West Central Texas this afternoon and early evening.
The most favored area for severe storms will be north of a line
from Big Lake to San Saba. Any storms that develop will be
capable of very large hail, damaging winds and tornadoes.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Hot temperatures at or above 100 degrees are possible on Monday
with high humidity. These conditions could result in heat indices
around 105 degrees, which would lead to heat-related illnesses.

Chances for thunderstorms return on Tuesday and will continue
through Friday. Large hail, damaging winds, and lightning are will
be the main concerns with this activity.

.SPOTTER INFORMATION STATEMENT...
Spotter activation will likely be needed this afternoon and evening.
