.SYNOPSIS...
Issued at 110 AM CDT Tue Jul 28 2026
H5 analysis tonight had a large area of high pressure
located over the southwestern CONUS. A ridge extended north of the
high into Wyoming. On the northern periphery of the high, weak
disturbances were noted from eastern Wyoming into western Nebraska
and western South Dakota. These disturbances have transitioned east
this evening and have led to thunderstorm development across a large
portion of the forecast area. Some of this activity was severe
earlier this evening, but as of the early overnight hours, this
activity has significantly decreased in intensity.
&&
.SHORT TERM /THROUGH WEDNESDAY/...
Issued at 110 AM CDT Tue Jul 28 2026
High pressure aloft will remain anchored over the SW CONUS over
the next 36 hours. Upper level disturbances, rotating around
the northern periphery of the high, will bring chances of
showers and thunderstorms to the region over the next 36 hours.
ATTM the main threat will be during the late afternoon and
evening hours-timed to the greatest instability. For today,
ongoing convection across central and south central Nebraska,
will force a frontal boundary south into Kansas. With easterly
flow north of this feature across the forecast area, high
temperatures today will run 5 to 10 degrees cooler than Monday`s
readings. This will lead to highs generally in the upper 80s to
lower 90s across the area. Later this afternoon, showers and
thunderstorms will develop along the front ranges of Colorado
and Wyoming INVOF a weak surface trough and sb capes of 1500 to
2500 J/KG. This area will also be underneath a favorable area of
Theta e and decent mid level lapse rates. Low amplitude west-
northwest flow will carry this activity east-southeast, possibly
impacting western and southwestern portions of the forecast
area Tuesday evening. As for the severe threat, the greatest
instability remains over the Nebraska Panhandle, so am expecting
the greatest severe threat there. Further east, sb CAPES are
not as favorable for severe storms with meager deep layer shear
of 25 to 30 KTS noted. Any storms which do become severe should
be marginally severe with mainly quarter size hail and wind
gusts to around 60 MPH and over far western and southwestern
portions of the forecast area. Overnight, this activity will
ride southwest and south of the forecast area as west
northwesterly winds carry this activity into Kansas.
Wednesday will be a near carbon copy of today`s setup. High
temperatures will be in the upper 80s to lower 90s.
Thunderstorms will once again develop off to the west of the
forecast area along the front ranges of Colorado and Wyoming.
Mid level winds will be more westerly on Wednesday afternoon and
evening. This setup will be more favorable for activity to
impact the forecast area and thus the higher pops Wednesday
afternoon into Wednesday night. As for the severe threat, once
again, SB CAPES, theta e ridging and mid level lapse rates are
most favorable across the Panhandle. As activity moves east into
the evening hours, weakening instability and decreased CAPES
will limit the overall severe threat. However, decent moisture
availability ie. PWATS of around 1.5 inches will be favorable
for possible heavy rainfall.

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
Issued at 110 AM CDT Tue Jul 28 2026
Northwest flow will continue through the end of the week. A
disturbance on Thursday will bring a chance for showers and
thunderstorms throughout the day. The Upper level ridge then
begins to build back in from the west pushing the northwest flow
eastward with the ridge becoming centered over the central
CONUS. WAA increases to the region by the latter half of the
weekend and will start to see a return to hot temperatures with
highs reaching mid 90s Sunday and Monday. At this time although
there will be hotter temperatures and low level moisture does
increase, heat indicies will still remain below any heat
headline criteria. Will need to continue to monitor as we get
closer to the weekend into early next week.
As far as precipitation potential for the end of the week into
the weekend, at this time expect mostly dry conditions, Friday
through Sunday as the region remains under the upper level ridge.
As for fire weather concerns, it will remain low through the
end of the week, then will need to monitor heading into the
weekend as dry conditions move in with warmer temperatures.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 637 AM CDT Tue Jul 28 2026
Patchy fog will be possible through mid-morning for portions of
the northern Sandhills, including KVTN terminal with MVFR
conditions possible. There will also be a chance of showers and
thunderstorms this afternoon and evening across western Nebraska
with the greatest chance of precipitation during the evening
hours. Winds will generally be out of the east around 5 to 10
kts through the day, becoming light and variable tonight.
