Severe Thunderstorm Warning 290, NWS Hastings, NE

AREA FORECAST DISCUSSION

.DISCUSSION...(This evening through Tuesday)
Issued at 337 PM CDT Tue Jul 26 2022

The main concern in the near-term is the chance for periodic showers
and thunderstorms over the next few days.  Expect an active pattern
over the next few days as an upper ridge sits over the Western CONUS
and an upper trough extends from Western Montana to the Great Lakes.

Fog and cloud cover stuck around a little longer than initially
expected, so temperatures in the southwestern portion of the
forecast area have been reduced accordingly, with highs today in the
upper 70s to mid-80s.  Showers and thunderstorms are ongoing across
our Kansas counties, with additional thunderstorm activity to the
northwest of the coverage area.  Chances for showers and
thunderstorms will increase over the next few hours along a boundary
extending southwest to northeast across the area.  SBCAPE values of
2000-3000 J/kg and shear values of 35-40kts are conducive for
development of a few strong to severe storms along the boundary. Any
storms that develop will have the potential of producing some large
hail and strong wind gusts.

Overnight, temperatures are expected to fall into the 60s.
Decreasing clouds overnight, radiational cooling and light upslope
winds will be conducive for at least a mention of fog around
sunrise.

Wednesday, the upper ridge moves slightly eastward and temperatures
return to the mid-80s across the area.  Showers and thunderstorms
are expected to develop to our west during the afternoon hours,
moving east overnight.  This will give us the best chance of
widespread precipitation chances across the area.  There is a chance
of a few strong to severe thunderstorms early in the evening for the
western part of the area.

Slightly cooler temperatures are in the forecast for Thursday
through Saturday as a surface front stalls over the area.  Highs
will be primarily in the 70s and 80s and lows will be in the 50s and
60s. Daily chances for showers and thunderstorms will be possible
along and south of the boundary.

The pattern starts to shift on Sunday as an upper ridge moves to the
east over the area.  A few isolated thunderstorms will still be
possible on Sunday evening and overnight.  This will give way to a
drying period and temperatures returning to the 90s.

.AVIATION...(For the 18Z KGRI/KEAR TAFS through 18Z Wednesday)
Issued at 1236 PM CDT Tue Jul 26 2022

Visibility and ceilings have improved to VFR over the last several
hours. Satellite still shows fog in the southwestern part of the
area, eroding from northeast to southwest. Expect southerly winds
to continue through the early afternoon with mostly clear skies.
Things become a little more dicey in terms of cloud cover and
thunderstorm potential from around 22Z through late evening.

Scattered thunderstorms will be possible along a frontal boundary,
scooting from northwest to southeast across the area this
afternoon and evening. Thunderstorm coverage is not anticipated to
be widespread, but both terminals may encounter some storms.
Expect brief periods of reduced visibility due to rainfall, hail,
and wind shifts with any storms moving through. Storms are
currently anticipated to move out of the area by midnight.

Clearing skies, light upslope winds, and moisture from recent
rain, brings some concern for some fog development around
sunrise. Confidence in this situation is low for the time being,
so this has been omitted from prevailing conditions.
