.SHORT TERM...
(This evening through Sunday)
Issued at 217 PM CDT Sat May 4 2024

Main concern for today remains the threat for severe weather this
afternoon which is dependent on the location of the cold front. As
of 2 pm, the cold front is located along a line from the Guadalupe
Mountains to Midland and is continuing to move south but gradually
slowing as it does so. Based on the location of the front the severe
weather threat for our area is not as high as it was earlier today
however any left splitting supercell may still enter our area and
pose a large hail threat mainly across our southern row of counties
hence a Severe Thunderstorm Watch has been issued for those
counties until 10 pm. Upper-level lift is still expected to
increase as we go through the late afternoon and early evening as
a shortwave swings across the forecast area. This should lead to
additional shower and thunderstorm development across the South
Plains and Rolling Plains which will shift east through the
evening and come to an end around midnight for most locations.
However, low clouds and the potential for drizzle will continue
through the morning hours. These low clouds will keep temperatures
mild once again overnight only dropping into the 50s. Low clouds
will be slow to dissipate tomorrow but by early afternoon at least
a few peaks of sun are expected. This low cloud cover will keep
temperatures cool tomorrow in the upper 60s to lower 70s despite
the breezy southerly winds. /WI

Ensemble and deterministic models continue to hint at the
possibility for thunderstorm development across the eastern Rolling
Plains and far southeastern Texas Panhandle Monday afternoon and
evening. An upper level trough and associated low over the western
CONUS will make its way into eastern Colorado early Monday morning,
which will work with the northeastward moving surface low, to push
the dry-line eastward across the FA. However how far east the dry-
line pushes remains uncertain, with recent model guidance suggesting
slightly weaker winds which may work to keep the dry-line over our
far eastern column of counties. If this were to come into fruition,
we could see isolated thunderstorms develop across the far
southeastern Texas Panhandle and eastern Rolling Plains late Monday
afternoon.

The trough will quickly eject north into the High Plains Monday
night allowing for zonal flow to prevail over the forecast area
through mid-week. Surface troughing in the lee of the Rockies will
develop Tuesday tightening the pressure gradient across the
region. This will lead to breezy southwest winds Tuesday and
Wednesday around 15 to 20 mph with gusts up to 30 mph. These
breezy conditions in combination with warm temperatures and dry
conditions may lead to elevated to near critical fire weather
concerns across the Caprock. By Thursday we will finally find some
relief from the warmer temperatures as a vertically stacked low
over the High Plains elongates across the southwestern United
States which will sling a cold front across the region into the
early morning hours Thursday. No precipitation is expected with
this front sadly but will provide much cooler temperatures through
the end of the week in the 60s and 70s. Our next chance of
precipitation arrives Saturday as a shortwave trough begin to
approach the region from western CONUS.

Mixed layers of stratus with IFR at LBB and MVFR and VFR elsewhere
should soon consolidate to IFR and remain this way for much of
the morning. Confidence is high in stratus rising to MVFR around
midday and then VFR through the afternoon with light winds.
