Severe Thunderstorm Warning 250, NWS North Platte, NE

Area Forecast Discussion
National Weather Service North Platte NE
133 PM CDT Tue Jul 26 2022

.SHORT TERM...(This evening through Wednesday night)
Issued at 132 PM CDT Tue Jul 26 2022

A large upper level area of low pressure will remain located near
Hudson Bay through Wednesday. Meanwhile upper level ridging has
expanded northward across the Pacific west coast states. Between the
two features moderately strong west-northwest flow aloft is in place
across our region. At the surface a weak cold front is sagging
southward through the area. The front by early this evening should
extend from northeast CO through central into northeast NE. Most CAM
guidance develops scattered convection late this afternoon near the
front, but this is mostly just south and east of our counties of
western and north central Nebraska. There has been a signal the past
several runs of the HRRR that a few storms could develop in the
moist post frontal upslope environment across the western Sandhills.
If these were to form then a small cluster could move southeast
across central into southwest NE early this evening. Clearing is
taking place across the area late this morning, and will allow for
some instability to develop this afternoon. Shear is such that storm
organization could occur with a few briefly severe cores possible.

A small disturbance embedded within the flow aloft may bring another
cluster of showers/thunder to the area late tonight into Wednesday
morning. Moisture will certainly not be lacking, with east to
southeast low-level flow north of the weak cold front continuing to
advect Gulf moisture northwest into the area. PWATS will average
around 1.25" so spotty heavy rain is possible. Unclear has to how
much clearing will occur during the day Wednesday. Several CAMs
linger mid-level showery activity through much of the day. Does
appear that at least some clearing will take place farther to the
west across the Panhandle into northern CO. This is where the
better instability would develop, and most models suggest a
cluster of storms should materialize and track southeast
toward/through southwest NE and northwest KS Thursday night.

.LONG TERM...(Thursday through Tuesday)
Issued at 132 PM CDT Tue Jul 26 2022

The upper low near Hudson Bay will shift eastward by the weekend.
Meanwhile the upper ridge across the western CONUS will begin to
build farther to the east across the Rockies. A weak nearly
stationary front will remain draped across the High Plains from
western KS into the NE Panhandle. Several rounds of showers/thunder
are expected across this area into the weekend. Unfortunately the
main focus for precipitation looks to remain mostly south and
southwest of our area. The exception will be across southwest nearer
the front and stands the better chance of seeing at least some
rainfall. The heat will gradually build back into the area as the
upper level high builds toward the Central Plains next week. Highs
by Monday and Tuesday will be back into the 90s to lower 100s.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1211 PM CDT Tue Jul 26 2022

A cold front will move southeast this afternoon that will make a
range from IFR to VFR conditions across the area tonight. Short
term models are in good agreement convection will redevelop along
the front, although areal coverage creates a spread. The forecast
is for isolated to scattered thunderstorms from 3 pm to 10 pm
tonight then clearing across much of the area. The exception will
be across the far southwest three counties where stratus and fog
may still redevelop and visibility dropping to a mile at times
with IFR to LIFR conditions possible. Overnight mid and high
clouds spread in from the northwest with cigs AOB 8KFT.

251 PM CDT Tue Jul 26 2022 /151 PM MDT Tue Jul 26 2022/

This Hazardous Weather Outlook is for portions of western and
north central Nebraska.

.DAY ONE...TONIGHT.

There is a marginal risk for severe thunderstorm development this
afternoon. A frontal boundary will move southeast through western
into central Nebraska that will be the focus for scattered
thunderstorm development. Scattered thunderstorms are expected to
develop, where a few severe thunderstorms will make possible the
threat for large hail and damaging winds until the front moves
southeast of the area near midnight. All thunderstorms pose the
threat of lightning.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.

Wednesday as the front moves south across Kansas the boundary
will extend northwest across the high plains that will remain the
focus for thunderstorm development Wednesday. A marginal risk
exists for portions of the southern Nebraska Panhandle and
southwest for areas generally west of a line from Rushville to
Oconto and Eustis. Large hail and damaging winds are the main
hazards.

The frontal boundary will remain the focus for daily thunderstorm
chances Thursday through Saturday. Sunday another frontal system
is forecast to push southeast for a greater areal coverage for
thunderstorms through Monday. At this time, the severe threat is
uncertain into the extended period.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not expected through tonight.
