Area Forecast Discussion
National Weather Service North Platte NE
905 PM CDT Tue Aug 1 2023

...Forecast Update...

.SYNOPSIS...
Issued at 1216 PM CDT Tue Aug 1 2023

Key Messages:

Thunderstorm chances and the associated wind threat will be the
concern for tonight.

A quiet weather day is expected Wednesday with storm chances
returning for the end of the week.

Much cooler weather is expected by Sunday into the first of next
week as a strong disturbance and cold front cross the area.

&&

.UPDATE...
Issued at 903 PM CDT Tue Aug 1 2023

Satellite and radar suggest a MCS is forming across nrn Neb/srn
SD. A forecast update is in place for this feature using the 18z
NAMnest. Some thunderstorms tonight will be capable of producing
locally heavy rainfall which could cause flooding in some areas.

&&

.SHORT TERM...(This evening through Wednesday night)
Issued at 1216 PM CDT Tue Aug 1 2023

A warm front is located just south of the NE/KS border this
afternoon. This front should remain nearly stationary into this
evening as a weak area of low pressure develops across western KS in
response to a weak shortwave crossing CO. This wave should help to
enhance convective development along the Front Range late this
afternoon. CAMs grow this convection into a decent size cluster
across northeast CO into the southern NE Panhandle by early this
evening. Westerly flow atop low-level easterlies north of the warm
front will help to enhance the overall shear profiles this evening
across southwest NE. CAPE will be sufficiently strong for upscale
growth as this cluster moves eastward across southwest NE and into
northwest KS this evening. DCAPE values will be supportive of strong
wind gusts, particularly near and south of I-80. PWATS are quite high
as well in this area, with persistent easterly low-level flow
maintaining a high moisture content at the low-levels. Meanwhile the
mid and upper levels continue to see moisture advection from the
southwest CONUS on the periphery of the Southern Plains upper level
high. This all could lead to heavy rainfall intensity, but the
complex of storms should move through fast enough to limit the
threat of flooding.

A fairly quiet day is expected Wednesday in the wake of the complex
of storms expected tonight. The warm front in KS will settle
southward toward the southern part of the state as the weak surface
low migrates eastward across KS through the day. Low-level flow will
remain east-northeast (upslope) across the area Wednesday, but the
lack of any defined disturbance should limit the amount of convection
developing off the higher terrain. Still a loosely organized
cluster or two could emerge eastward Wednesday evening and would
contain locally gusty winds.

.LONG TERM...(Thursday through Tuesday)
Issued at 1216 PM CDT Tue Aug 1 2023

The expansive upper level ridge of high pressure will continue to be
located across the Southern Plains Thursday into Friday. A weak
disturbance rotating northeastward on the western periphery of the
high will amplify as it reaches the northern Rockies by Friday.
Westerly upper level flow should increase somewhat across our area
as this occurs. In addition, lift will be enhanced, and could be a
rather wet period Thursday night through Friday. Some potential for
severe during this time with the increased flow aloft, but there
also could be abundant cloud cover which would limit the
instability. The system turns east and crosses the Northern Plains
Saturday into Sunday. This will drive a significant cold front
southward through the area, reaching all the way to the Red River
Valley by Monday. A somewhat drier modified Canadian airmass will
surge into the area behind the front Monday into Tuesday. High
temperatures Monday and Tuesday will be well below normal in the
wake of the front, with highs mostly in the 70s.

&&

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)
Issued at 625 PM CDT Tue Aug 1 2023

VFR conditions expected outside of thunderstorms, though
significant storms may impact KLBF and possibly KVTN.

Will use VCTS and a TEMPO group 04Z to 07Z at KLBF where
confidence in convection is higher, but just a VCTS at KVTN. Winds
especially at KLBF may gust to 40kt or higher as thunderstorms
organize into a complex and move across southern Nebraska. Will
adjust timing and magnitude of winds and weather once radar trends
become established. Showers/storms will linger through late
tonight but expect VFR with any lingering showers exiting off to
the east by 12Z. VFR conditions with winds generally at or below
10kt are expected to persist through the latter portion of the
valid period.
