.SHORT TERM ...
(This evening through Thursday night)
Issued at 159 PM CDT Wed May 8 2024

Surface winds have been light and variable around the combined
Panhandles this morning with a stalled surface boundary (cold
front) over the area. This boundary is to retreat to the
northeast late this afternoon with westerly winds picking up to
potentially 20 mph gusting 30 mph for the southwest TX Panhandle
for a few hours this evening. The front in the north is progged to
push south late tonight with northerly winds overtaking the area.
The main push of CAA advection behind this front is expected
tomorrow, but also the upsloping winds will help keep
temperatures on the cooler side tomorrow with highs in the upper
60s across the northwestern combined Panhandles and 70s over the
rest of the combined Panhandles. Tomorrow afternoon surface winds
are progged to become more easterly with the southern half of the
Texas Panhandle seeing winds pick up to around 20 mph. Besides
some breezy winds and temperatures turning cooler tomorrow,
overall the weather is expected to be benign in the short term.

.LONG TERM ...
(Friday through next Tuesday)
Issued at 159 PM CDT Wed May 8 2024

A large upper level low will be found over the Great Basin on
Friday. The Panhandles will be in a zonal to somewhat southwest flow
aloft ahead of this low.

As the low moves across the 4-corners region, the flow aloft will
become increasingly southwest through the weekend. Then the upper
level low is expected to track east across southeast Colorado and
southwest Kansas Sunday night into Monday. The models are in fairly
good agreement on the track of the upper low, but they disagree on
the the strength and speed of the low.

Showers and thunderstorms may start as early as Friday evening in
the west and showers and storms may linger as late as early Tuesday
morning in the east.  Another system in the northwest flow aloft may
bring some showers and storms to the area Tuesday and Tuesday night.
As the event gets closer, the time window for rain will likely
shrink as models come into better agreement with the speed of the
upper level low.  Latest ensemble forecasts suggest that the
Panhandles have a 50 to 60 percent probability of seeing at least
0.5" of rain from Friday through Monday night.  There could be a
severe storm or two during this forecast, but it does not look like
a favorable set up for days and days of severe weather in the
Panhandles.

(00Z TAFS)
Issued at 618 PM CDT Wed May 8 2024

Breezy conditions are currently holding at all terminals this
early evening with potential to see gust nearing the 25kt mark.
These speeds could hold into the overnight with most areas not
calming till the morning hours. On the directional side, expect
all terminals to slowly transition to a more easterly direction by
Thursday morning with KGUY already seeing surface winds out of
that direction now. This transition will also correspond to
moisture and clouds building in over the terminals with a broken
cloud deck expected over the north late tonight. However, VFR
conditions should remain clear into Thursday morning with CIGs
expected to stay high on these cloud decks.
