.KEY MESSAGES...
Issued at 241 PM CDT Thu Apr 24 2025

- Isolated to potentially scattered severe thunderstorms possible
  again today with the primary hazards being large to destructive
  hail (baseball size or larger), damaging wind gusts, and heavy
  rainfall. A tornado cannot be ruled out.

- A cold front on Friday will determine the amount the TX
  Panhandle that will have the potentially for severe storms once
  again.

-Thunderstorms with maybe a severe potential may be possible
 through the rest of the forecast period as well.

.SHORT TERM ...
(This evening through Friday night)
Issued at 241 PM CDT Thu Apr 24 2025

As of this writing, a shroud of low clouds is starting to break up
and give way to some sunshine. Dewpoints across the combined
Panhandles are sitting near 60 for the central to southeastern
Panhandles with dewpoints dropping off to the lower 50s in the
northwest. A severe thunderstorm potential does exist today.
However, CAMS are all over the place with initiation this
afternoon. Some are initiating storms as far west as Dumas and
Umbarger line. However, much of the models also have negative
theta-e advection at H7 moving into the west leaving only the far
eastern Panhandles favorable for thunderstorm production. A 20Z
balloon release is scheduled and should give a better idea of
available moisture especially from H7 to H5.

One thing to watch will be the strengthening and positioning of
a dryline. Tds are progged to eventually decrease in the west,
which will help dry line mix east. As of this time the dry line
may only mix to the central Panhandles with storms initiating
across the central Panhandles and move into the eastern
Panhandles. Storm along this dryline may initiate from convective
temperatures being reached, but will have to watch the OK
Panhandle for help from a shortwave that may create a small
convective complex across the northern combined Panhandles going
into this evening before moving into western OK. Discrete storms
along the dryline south of this cold front are expected to be
isolated in nature and would not expected widespread storms across
the FA.

With SBCAPE progged to be above 2k J/Kg and bulk shear around 40
to 50 kts, just east of the dryline, there will be a decent chance
to see at least one decent supercell somewhere in the eastern TX
Panhandle. After what yesterday's storms produced would not rule
out some hail around 3" potentially being associated with a
healthy supercell in this environment.

LCL's are currently around 1KM with the abundant surface moisture
and low clouds that we have been seeing this morning. With Tds
expected to stay in the lower 60s across the eastern third to half
of the combined Panhandles late into the afternoon a tornadic
supercell cannot be ruled out at this time. The NAMnest does have
a modest 100 to 150 m^2 per s^2 0-1KM storm relative helicity. SPC
has upped the tornado outlook to a 5% since this morning. Will
have to watch any healthy supercells closely for attempts to form
a tornado and not just the large hail today. Again not
anticipating more than a couple of healthy supercells late this
afternoon into early evening.

The cold front coming in from the north tonight may or may not be
a factor in the thunderstorm production. However, cold pooling
form thunderstorms may bring it in a lot sooner than what some of
the short term models want to bring it in. Tomorrow, there is
quite the discrepancy for if this front will retreat enough to
bring Amarillo's highs into the 70s or not. Tomorrow's bust
potential for high temperatures is fairly high especially if the
front does not retreat like the models suggest. Afternoon
temperatures, especially across the northern Panhandles, are
expected to only rise into the 60s. The position of the front
will also be key to how much of the TX Panhandle will have a
marginal severe threat for tomorrow afternoon.

.LONG TERM ...
(Saturday through next Wednesday)
Issued at 241 PM CDT Thu Apr 24 2025

Northwest flow aloft is looking to dominate the FA over the
weekend with a mid to upper level trough digging over the PacNW
into central CA on Sat. A closed low associated with this trough
is progged to form over central to northern CA late Sat as well.
Ridging is expected to build over the FA through Mon ahead of the
upper level trough. Showers and thunderstorms chances are
expected to continue through the extended period. The highest and
more widespread precipitation chances will be on Sat with each
subsequent day having a 20 to 40 percent chance, favoring
different regions of the combined Panhandles each day.

Saturday southeasterly surface winds will continue to feed in low
level moisture with an upslope aspect to the winds helping to
maintain cloud cover. On Saturday, with the aforementioned closed
low setting up up stream of the Southern Plains the FA will fall
under some divergence aloft helping to created showers and
thunderstorms with the abundant low level moisture expected. PoPs
are currently upwards of 50 to 80 percent for much of the day on
Saturday. However, not expecting any heavy rains just some steady
light rain which may end up giving some areas upwards of 0.25"
over a period of 6 to 8 hours or so. Because of the amount of
cloud cover expected on Sat, daytime temperatures are expected to
be in the upper 60s to lower 70s.

It is not until Sun, when the combined Panhandles break out of the
clouds and also warm back up into the 80s. Monday will be the same
way with highs in the 80s before the next cool down on Tuesday
with highs back in the 70s. Early Tuesday morning a weak cold
front is progged to come through the area thanks to the
aforementioned closed low finally making its way to the portions
of the Central to Southern Great Plains. By this time though, the
low should be coming across as an open wave. Details on the
extended and severe threat well into Wed are unknown at this time,
but would not rule out the potential for this time of year.

.AVIATION...
(00Z TAFS)
Issued at 626 PM CDT Thu Apr 24 2025

VFR conditions are expected throughout the 00Z TAF period at all
TAF sites. Winds will be out of thew SW and S to start, before
shifting to northerly behind passing cold front between 06-12Z
Friday. Winds will be 10-20 kts. Some MVFR and IFR cigs are
possible in the wake of the cold front through the remainder of
the TAF period. Will AMD as observations and trends reflect
current conditions through the second half of the TAF period.
