.SYNOPSIS...
Issued at 334 PM CDT Fri Aug 2 2024

An upper level ridge is settled over the western United States, with
fairly weak northerly flow aloft over western Nebraska. At the
surface, an area of high pressure is located over south central
Nebraska, with a surface trof to the lee of the Rockies. On
satellite, cumulus is developing across southeastern Wyoming,
northwest Nebraska, and the western Nebraska Panhandle.

&&

.SHORT TERM /THROUGH SATURDAY NIGHT/...
Issued at 334 PM CDT Fri Aug 2 2024

The surface trof will be the focus for thunderstorm activity the
rest of this afternoon and evening. As of this afternoon, cumulus is
already developing along the boundary. Across the Panhandle, CAPE
values are around 1000 to 1500 J/kg. Shear is quite meager, around
20 kts. Also worth noting, the model trends backing off the tongue
of theta-e across western Kansas. Model soundings indicate inverted
V patterns in the lower atmosphere, supporting the potential for
strong gusts with storms. As storms continue to develop this
afternoon and evening, they should remain fairly isolated to
scattered in nature. While some guidance suggests a brief linear
system forming and tracking across northeast Colorado, the trends
have been towards a more multi cellular mode, with some of the
stronger cells having potential for wind gusts and hail. As the
storms weaken, showers may be expected to continue through Saturday
morning, most notable along southwest Nebraska.

Saturday afternoon will be fairly quiet across the region. As the
showers and cloud cover move out of the region in the morning, skies
become mostly sunny, with no additional precipitation expected.
Guidance has slightly cooled down high temperatures, generally only
1 to 2 degrees and most notably for areas along and south of
Interstate 80. In general, expecting low to mid 90s along and south
of Interstate 80, with mid to upper 90s and possibly 100
degrees across the Sandhills and north central Nebraska.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 334 PM CDT Fri Aug 2 2024

The upper level ridge continues through early in the week. Sunday
evening, as a shortwave progresses through the flow, a low pressure
system is forecast to track through South Dakota. This will be the
focus for a few showers and thunderstorms, most likely across
portions of northern Nebraska. Otherwise, most of the area will
remain warm and dry, with mid to upper 90s for the highs on Sunday.
As an upper level trough begins to push through southwestern Canada
on Monday, a surface low forms out in front. The low is expected to
track a cold front across portions of the region, bringing some
slightly cooler temperatures, mostly in the upper 80s to lower 90s.

By Tuesday, the trough should help to flatten out the ridge, and
bringing a more zonal pattern through the end of the week. From
Tuesday evening through the end of the week, there will be chances
of showers and thunderstorms, which may bring some beneficial
rainfall across the region. The zonal pattern is also expected to
bring some slightly cooler temperatures as well, with highs cooling
off as the week progresses. For now, the expected drop would be from
the low 90s on Tuesday to upper 70s by Friday. Future forecasts will
continue to refine timing and amounts. However, confidence continues
to grow in a return to a cooler, wetter pattern through the end of
the week.

high clouds overnight with ceilings around 25000 FT AGL.
