.SHORT TERM...
(This evening through Tuesday Night)
Issued at 132 PM CDT Mon Apr 22 2024

Another cool night is expected with lows in the low to mid 50s.
These temperatures are very close to seasonal normals. An upper
level trough will track across the Northern Plains Monday night into
Tuesday morning, sending a weak cold front into the northern Big
Country by late Tuesday afternoon. The front may serve as a lifting
mechanism and result in the development of isolated showers and
thunderstorms by late in the afternoon, mainly across the northern
Big Country. Any storms that do develop may be strong to severe,
with large hail and damaging winds being the main hazards. This
activity will then spread south and east through the evening hours,
with most of the storms dissipating by mid to late evening. Although
a few storms could sneak south of I-20, most of the activity should
remain to the north of I-20. Highs on Tuesday will be in the 80s to
near 90, with overnight lows in the upper 50s to lower 60s.

.LONG TERM...
(Tuesday through Sunday)
Issued at 440 AM CDT Mon Apr 22 2024

The warming trend will continue Tuesday into Wednesday, with warmer
temperatures sustained late this week into the weekend. Going
through the next 7 days, will be monitoring several possibilities
for thunderstorms.

Breezy south winds are expected on Tuesday, and afternoon highs are
expected to range from the lower 80s in some of our far
eastern/southeastern counties, to the mid/upper 80s in much of the
Big Country and Concho Valley. With an upper trough moving southeast
across parts of the Midwest, trailing portion of associated cold
front is forecast to move through southwestern Oklahoma and into
parts of northwest Texas by Tuesday evening. The front is progged to
stall near or just north of Haskell/Throckmorton Counties Tuesday
night, and stay quasi-stationary through Wednesday. Will have a
conditional possibility for a few strong to severe storms in mainly
the northern Big Country Tuesday evening into early Tuesday night.
With moderate instability and sufficient vertical shear, the main
potential hazards will be large hail and damaging winds if storms
can develop.

Wednesday will be warm and more humid with dewpoints climbing into
the 60s, as south winds continue the low-level moisture transport
into our area. Highs are expected to range from the lower 80s in our
far northern and eastern counties, to the mid/upper 80s
elsewhere. An upper level ridge will shift east across Texas
Wednesday and Wednesday night.

An upper trough over the Desert Southwest Thursday morning will lift
across New Mexico/Colorado Thursday night and into the central/
southern High Plains Friday morning. For our area, will have deeper
moisture in place with a sharpened dryline to our west. The main
chance of thunderstorms will be in our western/northwestern counties
Thursday evening just ahead of the dryline, and across mainly the
northern third of our area Thursday night closer to the better upper
support. With CAPEs 1500-2000 J/kg and effective bulk shear around
35 knots, strong to severe storms will be possible, especially in
the Big Country. The main threats include large hail and damaging
winds.

The dryline will advance east across much of our area on Friday, and
mainly the eastern third of our area will have a chance of
thunderstorms Friday afternoon and early evening. Given the forecast
strength of the wind fields aloft and instability, may have to
monitor the potential for severe weather in some of our northern and
eastern counties Friday afternoon. Highs Friday are expected to be
mostly in the mid to upper 80s.

Low-level moisture will make a quick return across our area Friday
night with a retreating dryline. This to occur as another upper
trough deepens into the southwestern CONUS by Saturday morning. Per
the medium range models, an upper trough is progged to move east
across New Mexico Saturday afternoon/early Saturday night, then lift
northeast into eastern Colorado or western Kansas Sunday morning.
Storm development looks possible Saturday afternoon/evening in the
eastern Big Country toward Coleman/Brown Counties, with a possible
lead wave moving over the area aloft, and ahead of a dryline. Will
have a possibility of additional storm development across a larger
part of our area  Saturday night (highest chance northern/eastern
counties) with the dryline/weak Pacific front moving east into the
area. At this time, have low PoPs (20-30 percent) for a lingering
possibility of showers and thunderstorms Sunday afternoon in our far
eastern counties. Daytime temperatures look very warm for the
weekend with highs in the upper 80s to lower 90s for much of our
area.

Gusty south winds of 10 to 12 knots will decrease this evening.
Expect winds at KABI to pick back up to 12 to 14 knots around 04Z.
Stratus will overspread the area Tuesday morning, resulting in
MVFR ceilings at all sites, except KABI. Expect VFR conditions to
return by late morning or early afternoon. West to southwest winds
will increase to 12 to 15 knots by late morning.
