.SHORT TERM ...
(This evening through Thursday night)
Issued at 216 PM CDT Wed Jun 12 2024

Cumulus clouds have developed in northeast New Mexico into southeast
Colorado along a surface trough.  With surface temperatures in the
mid 90`s along this trough, there may be just enough instability to
produce a shower or thunderstorm in our northwest CWA along this
trough late this afternoon and evening.  Storms may produce strong
gusty winds and small hail.

Thunderstorms will be possible again on Thursday, mainly across the
northern CWA.  This is where the best convergence will be along a
surface trough.  Storms will likely be slow moving as the winds
aloft are expected to be light.

Southerly winds will be common in the 10 to 20 mph range with
occasional higher gusts tonight through Thursday night.

Many places may reach 100 degrees or higher on Thursday we may need
to consider heat advisories for Palo Duro Canyon and parts of the
Canadian River Valley.

.LONG TERM ...
(Friday through next Tuesday)
Issued at 216 PM CDT Wed Jun 12 2024

Friday should have our best chances for showers and thunderstorms
for the Panhandles. The best chances will be for the western and
northern combined Panhandles as an H500 trough moves ENE across
northern NM and southern CO before exiting the northern Panhandles
by Saturday morning. Although a good surface of lift with the
trough is present, overall CAPE and shear is quite anemic. Could
see a strong storm or two with strong wind gusts and small hail,
but a very low chance of severe thunderstorms are expected at this
time. Timing will have to be update with rain chances though,
since the latest 12/12Z model and numerical data are not in an
accord.

Depending on which model data you assess, the main trough axis
will slowly move through the northern Panhandles with the main
amplitude axis near PDC as it moves east. This area of lift could
provide additional diurnally driven showers and thunderstorms
(around 20-30% chance) favoring the central and eastern
Panhandles. Some storms could also be strong at times.

We dry out Sunday through early next week before our next rain
chances may come the end of the long term forecast period. High
temperatures throughout the long term forecast period will be
above average for mid June.

(06Z TAFS)
Issued at 1131 PM CDT Wed Jun 12 2024

All three terminals are expected to remain VFR through much of the
06Z TAF period. Winds are expected to stay with a southerly
component and less than 15 kts through the period. Some high
clouds are expected through the period. There will be slight
chance for a thunderstorm to impact KGUY and KDHT after 00Z
Friday. However, confidence is low enough to leave out of the TAFs
for now.
