(This evening through Sunday)
Issued at 211 PM CDT Sat May 6 2023

...Scattered strong to severe thunderstorms expected to develop
across northern and eastern portions of West Central Texas this
afternoon into this evening...

Satellite and radar images indicate some convection...mostly
elevated...developing across extreme southeast portions of the CWA
this afternoon. The latest HRRR progs convective initiation across
the northern and western counties between now and this
evening...mainly along the surface dryline. The dryline will be a
focus for showers and thunderstorms to develop this afternoon into
this evening and it appears the strongest convection will be across
the Big Country region this evening. SPC continues to advertise a
slight to enhanced risk of severe weather across the northern and
eastern portions of the CWA for this afternoon and evening. The main
hazards are very large hail (up to baseball size possible) and
damaging winds (60 to 80 mph) but an isolated tornado cannot be
ruled out.

Southwest flow aloft will continue to bring weak upper level
impulses across portions of northwest Texas tonight into tomorrow.
The dryline will continue to provide a focus for showers and

.LONG TERM...
(Sunday night through next Friday)
Issued at 211 PM CDT Sat May 6 2023

...Hot and unsettled pattern to continue for the foreseeable
future...

Not a whole lot of change from the previous long-term forecast. The
mid level ridge that has been the key player in our storm chances
the past few days will continue to drift off to the east. By Monday
the area will be in generally quasi-zonal flow with a broad, mid-
level trough beginning to take shape off of the west coast. This
will allow flow over our area to transition back into weak southwest
flow. This overall setup will help to continue the hot and unsettled
pattern we've been seeing over the past few days. Surface winds out
of the south will help to keep a moist boundary layer in place.
This, in turn, will allow the dryline to continue to take shape and
mix east during the day. Monday and Tuesday will see this dryline
activity allowing for chances of strong to severe storms with large
to very large hail being the main hazard along with damaging winds.
With continued moisture and afternoon highs expected to be in the
90s, SBCAPE values will be in the 2000-3000 J/kg range each
afternoon with steep low level lapse rates. As these storms are
generally expected to be high based, the tornado threat will
remain limited with a greater straight line wind threat from
potential downbursts. Activity these days currently looks to be
more isolated/scattered in nature and will greatly depend on both
the shortwave disturbances that move overhead as well as how far
east the dryline can mix through the day.

The aforementioned mid-level trough will begin to move east into the
Western CONUS late Monday before pushing north and east into the
Central Rockies by late Tuesday into Wednesday. The trough is
expected to deepen into a low and stall out over the north central
Rockies. This will put our area in weak south to southwest flow
for the end of the week and into the weekend. This will also usher
in some mid-level height falls, allowing temperatures a cool a
few degrees back into the 80s and lower 90s, starting on
Wednesday. Global models have backed off on precipitation chances
for the end of the work week, especially on Friday, so we have
followed suite with the forecast. That being said, both show very
wet weekends with highly saturated atmospheric profiles and
widespread showers and storms. With very little synoptic
convergence expected, the current thought is that showers will be
influenced by perturbations in the flow aloft. We are optimistic
that this will hold true as much of the area is still in desperate
need for rain but it's certainly not a guarantee. We will keep a
close eye on the end of the week but overall the warm and
unsettled pattern that is typical for spring down here will
continue for the foreseeable future.
