.SHORT TERM ...
(This evening through Sunday night)
Issued at 254 PM CDT Sat Jul 6 2024

Warmer temperatures are forecast across the area compared to
yesterday. 80`s and lower 90`s can be expected as 850 mb reside
in the upper 20`s (degrees Celsius) and cloud coverage should not
impose on day time heating this afternoon. Instead, coverage
should steadily increase towards the evening hours. Tomorrow, a
cold front will surge through the area from the north. Additional
cloud coverage and perhaps some precipitation chances will
restrict the northern Panhandles from warming up to the 90`s.
Instead, upper 70`s and 80`s are foreseen. Further south, 90
degree temperatures may still be met thanks to the timing of the
front. It may not pass through the whole CWA until the night time
hours; but of course, a faster frontal progression will lead to
lower day time highs overall.

A field of cumulus has generated over central portions of the
Texas and Oklahoma Panhandles. Tonight a disturbance from the
Rocky Mountain range in Colorado will advance southeast into our
area. The best environment and source of lift favors the Oklahoma
Panhandle and far northern portions of the Texas Panhandle. So
thunderstorm, some strong to severe, are possible ahead of the
boundary in the late evening hours and overnight period today.
Tomorrow, additional storms are expected to form in the eastern
Panhandles ahead of the incoming cold front. Severe storms are
possible again, with damaging winds, large hail, and a tornado or
two are the primary hazards. If convection can become more
widespread as opposed to isolated the tornado threat would
decrease, but the flash flooding potential would raise instead.
Finally, as Sunday night become Monday morning, another band of
showers should develop behind the main cold front and showers with
isolated storms will be possible for the central and eastern
zones of the CWA and last through Monday morning.

.LONG TERM ...
(Monday through next Friday)
Issued at 254 PM CDT Sat Jul 6 2024

Residual showers and thunderstorms in the wake of the cold front
should move south throughout the first half of Monday before H500
NW flow returns to the region at the base of the mid level trough
as seen by the latest 06/12Z model and numerical guidance. The
main trough axis should reach the Red River valley of north
central Texas by Monday night. This should help to steer what is
left of now Hurricane Beryl downstream of the trough axis and into
northeast Texas. For the Panhandles, some high clouds from the
remnant tropical system may reach our region, but thats about it.

Tuesday through the remainder of the long term forecast period,
the main H500 quasi-stationary high pressure system over the Great
Basin in the western CONUS, NW flow with diurnally driven showers
and thunderstorms are possible, favoring the central and western
Panhandles each day. Towards the end of the forecast period, H500
flow should become quite anemic with the main high shifting NE of
the Four Corners Region according to the latest guidance. This
should limit our precipitation chances. High temperatures to start
will be well below average and then rise back to above average by
the end of the forecast period.

.AVIATION...
(00Z TAFS)
Issued at 557 PM CDT Sat Jul 6 2024

Thunderstorms in the vicinity of KAMA capable of heavy rain,
lightning, and strong winds should move out and dissipate by
01-02z. After that, VFR conditions should be in place at all
sites, although some marginal LLWS is possible overnight into the
morning hours thanks to a strengthening low level jet. KGUY has
the best chance for LLWS, but mentions may be needed by the 06z
TAF issuance should confidence increase. Winds will switch from
southerly to north-northeasterly tomorrow as a front moves in.
