.SYNOPSIS...
Issued at 320 PM CDT Tue Jul 18 2023

  Wyoming, impacting portions of western and north central
  Nebraska this evening and overnight. A few strong or briefly
  sever storms are possible.

.SHORT TERM...(This evening through Wednesday night)
Issued at 320 PM CDT Tue Jul 18 2023

The upper flow over the region has become more zonal as an upper low
moves across southern Saskatchewan and an upper ridge centered over
New Mexico. Early morning convection across the east as well as
stratus across the west this morning has resulted in a substantial
capping inversion, especially across the southwest. MLCAPEs are
forecast to range from 2000-3000 J/KG by early evening east of the
Black Hills into south central SD into northern NE and down through
central NE. Mesoscale models differ in timing and location, with
POPS limited to 20-30 percent this evening and overnight. Based on
mid afternoon development just south and east of the Black Hills and
also in southeast WY, the western Sandhills and Sheridan and Cherry
County are likely to be affected initially. The SPC mesoanalysis
large hail parameter does favor the potential for very large hail
across north central Nebraska this evening, while minimized across
the central Sandhills and southwest. SPC also now has a slight risk
for severe storms across much of Sheridan and Cherry County for this
evening.

Wednesday, a weak cold front will push through. Highs will reach the
low to mid 80s. There will be a chance for morning showers and
thunderstorms across the northeast during the morning, with a better
chance for development during the afternoon in vicinity of the cold
front. SPC has a slight risk for sever storms generally east of a
line from Hayes Center through North Platte and O'Neill. Storms
should diminish by mid evening, although a slight chance to remain
across the southwest overnight.

.LONG TERM...(Thursday through Tuesday)
Issued at 320 PM CDT Tue Jul 18 2023

A reinforcement of cooler air arrives Thursday behind the front with
highs only from the 70s to near 80. Guidance continues to indicate a
focused area of storm development beginning in southeast WY and the
western Panhandle, then southeast into the western Sandhills and
southwest NE during the afternoon and evening. 0-6km bulk shear is
forecast to reach near 50kts, with a lack of instability. MUCAPEs
are less than 100 J/KG except south of I80 where values may exceed
500. General thunderstorms are expected at this time, although
significant rainfall is possible across portions of the southeast
panhandle into southwest NE. WPC has a marginal risk of excessive
rainfall south of a line from Alliance through North Platte and a
slight risk of excessive rainfall across the far southwest including
Imperial.

Thunderstorm chances remain Friday into Friday night with northwest
flow aloft and sufficient deep layer shear from 35-40kts. Develop
and coverage however looks very isolated.

An upper level ridge across the desert Southwest will build north
and east into Nebraska Saturday through Tuesday, as winds aloft
weaken. The intense heat across the Southern and Southwestern U.S.
will begin to be felt across western Nebraska with highs reaching
the low to mid 90s by Sunday and Monday and mid 90s Tuesday. A few
100 degrees highs are possible.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1233 PM CDT Tue Jul 18 2023

overnight, with the better chances expected across north central
Nebraska. Have introduced a PROB30 at KVTN from 03Z-08Z. At KLBF,
TSRA is not included attm. However, MVFR to IFR ceilings and
visibilities are possible, especially across southwest into
central Nebraska from 10Z-15Z. Have introduced TEMPO for 3SM BR
OVC003 at KLBF from 11Z-14Z.
