...New UPDATE, AVIATION...

.UPDATE...
Issued at 635 PM CDT Fri Jun 14 2024

Showers and thunderstorms continue to move into the Panhandles
form New Mexico at this time. Some of these storms have been
strong to severe and the Severe Thunderstorm Watch for the
northwest will continue for a few more hours. Have increased PoPs
given current radar trends as well as hi-res guidance indicating
these storms could last well into the overnight hours for the
central and west. Will have to keep a close eye on the
southwestern TX Panhandle as some guidance hints that this area
could see some heavy rainfall that could lead to flooding and/or
flash flooding this evening into the overnight hours.

.SHORT TERM ...
(This evening through Saturday night)
Issued at 226 PM CDT Fri Jun 14 2024

Our active synoptic pattern continues as a trough moves across
the central CONUS and the high pressure center at the H500 level
transitions eastward. More perturbations will exit lee side of
the Rocky Mountains and move in from the northwest generating
additional chances for thunderstorms heading into the weekend.

High temperatures today and tomorrow will range in the 90`s; and
with excellent moisture retention, humidity should generally be
on the higher side through the weekend. Thunderstorm activity will
also continue, especially for our northern zones, through the
short term period. In the afternoon each day, sufficient
instability and shear will be present for storms to become severe.
Damaging winds, torrential rainfall, and some hail will continue
to be the primary hazards. Places that have already received much
rainfall over these past few days may begin or continue to see
flooding risks.

Today, showers and thunderstorms are diminishing from our morning
convection. A new shortwave trough will move through from the
northwest and clusters of storms will enter the CWA later this
evening. Cold pools and early outflow from our previous convection
have a chance to hinder our severe potential. However, showers
should still occur given our favorable Theta-E profiles
positioned in the western CWA. After sunset, thunderstorm
endeavors should should taper off but showers can persist
overnight and into the morning hours.

Saturday, a new southwest oriented trough will impact the
combined Panhandles but coverage may be more limited unless
today`s setup under performs. And with this more traditional
spring time regime progged from our mesoscale features,
thunderstorm timing will be a bit earlier in the afternoon and
evening.

.LONG TERM ...
(Sunday through next Thursday)
Issued at 226 PM CDT Fri Jun 14 2024

Mostly dry conditions are expected to start the long term forecast
period. Latest 14/12Z model and numerical data shows a pronounced
sinusoidal synoptic pattern across the entire CONUS. Focusing on
the southern High Plains, H500 SW flow will help with LL
subsidence and keep the Panhandles mostly dry. By mid week next
week, as the main H500 anti-cyclonic feature over the eastern
2/3 CONUS expands back to the west, perturbations in the mid
levels should help to generate showers and thunderstorms. These
perturbations should allow very good low to mid level moisture
transport from the Gulf to reach the Panhandles. Better rain
chances return from mid week next week to the end of the forecast
period. Some storms could be strong, and with repeated rounds of
low level moisture with PWAT values in the 99th percentile for
June standards, we will have to watch the potential for flooding
during this time period.

.AVIATION...
(00Z TAFS)
Issued at 635 PM CDT Fri Jun 14 2024

Main aviation concern will be gusty west winds and thunderstorms
at all sites. Storms are already impacting KDHT and will impact
KAMA/KGUY in the next few hours. These storms could have sporadic
strong gusty winds associated with them in addition to decreased
visibility. Additional showers and storms are possible around or
after 06z and amendments or further refinements to the TAFs will
likely be needed. Showers and storms should move away from the
terminals before 12z and southwest winds with gusts up to 25 to
30 kts are forecast until the end of this TAF cycle.
