...UPDATE TO AVIATION...

.SHORT TERM...(This evening through Sunday night)
Issued at 103 PM CDT Sat Jul 22 2023

WV imagery indicates a northwest flow aloft prevailing across the
Western High Plains downstream of a building ridge edging east into
the Great Basin. Near the surface, a small area of high pressure is
shifting east across the Texas Panhandle into western Oklahoma.

There is a chance for isolated to widely scattered thunderstorms
this evening as a prevailing northwest flow aloft gradually
intensifies across central and portions of western Kansas. With
surface dewpoints holding in the mid/upper 60s(F) providing
sufficient instability, steepening mid-level lapse rates
coinciding with the arrival of a +60-65kt upper level jet core
nosing into northwest/north central Kansas will create conditions
for possible thunderstorm development late afternoon/early
evening. CAMs suggest potential initial development farthest north
in vicinity of the I-70 corridor with any storms then spreading
southward during the evening time period. Gradually increasingly
favorable deep layer (effective shear upward of 30-40kt) combined
with MLCAPE values upward of 1000 to 1500 J/kg will increase
severe potential with large hail and damaging winds the main
threats. Quieter conditions are likely Sunday as ridging aloft
continues to build as it edges farther east into the Western High
Plains.

Fairly seasonal temperatures are likely tonight with little change
to the general air mass across the high plains of western Kansas.
Expected lows generally down into the 60s(F). Prevailing low level
southerlies will pull warmer air into the area Sunday, pushing
afternoon highs well into the 90s(F).

.LONG TERM...(Monday through Saturday)
Issued at 141 PM CDT Sat Jul 22 2023

A hotter but drier/more tranquil pattern is likely through mid-week
as medium range ensembles indicate a broad upper level ridge shifting
slowly east across the Colorado Rockies into the Western High Plains.
Despite ample moisture providing sufficient instability, a weakening
flow aloft associated with the upper ridge axis will likely hinder
thunderstorm chances through much of the period. A deepening lee side
trough of low pressure in response to the approaching upper level high
will help enhance warm air advection into western Kansas Monday, pushing
H85 temperatures up into the upper 20s(C) in central Kansas to a little
above 30C in extreme southwest Kansas. Under plenty of sunshine, expect
afternoon highs up into the mid/upper 90s(F) to possibly 100F in some
locations. Similar temperatures are forecast through at least Wednesday
with upper ridge axis edging into the Western High Plains.

.AVIATION...(For the 00Z TAFS through 00Z Sunday evening)
Issued at 520 PM CDT Sat Jul 22 2023

Isolated to widely scattered thunderstorms will drift southward through
western Kansas this evening, potentially affecting the vicinity of KHYS,
KGCK, and KDDC generally after 00-02Z. Otherwise, VFR conditions are
expected to continue through early Sunday. South-southwest winds around
5 to 15kt are expected through early Sunday as lee side troughing
develops in eastern Colorado.
