.SYNOPSIS...
Issued at 308 PM CDT Sat Aug 9 2025

H5 analysis from earlier this morning had an area of low pressure
over southeastern Saskatchewan. A trough extended south of this
feature into northeastern Wyoming and southwestern South Dakota.
Ridging was present to the east of the low over the Great Lakes and
high pressure was anchored off the coast of northern California.
Within the trough of low pressure over the northern plains, several
embedded shortwaves were noted. The first over Idaho, a second over
northwestern Colorado and a third over northeastern Nebraska into
southeastern South Dakota. At the surface a frontal boundary
extended from southeastern Nebraska into central and southwestern
Kansas. This feature then extended northwest into central Colorado.
North of the front, winds were generally from the east or northeast.
Along a line extending from the southern Panhandle and northeastern
Colorado, east-northeast into the southern Sandhills and portions of
northeastern Nebraska, a broad area of mid level cloudiness was
present. Within this area, isolated showers and embedded
thunderstorms had been developing over the past 6 hours. As of 2 PM
CDT, activity extended from far northeastern Colorado into central
Lincoln county. Another area of showers extended from east of
Thedford to southeast of O'Neill, while an isolated thunderstorm was
located over west central Cherry County. Skies were partly to mostly
cloudy and temperatures as of 2 PM CDT ranged from 77 degrees at
Broken Bow to 84 degrees at Ogallala.

.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 308 PM CDT Sat Aug 9 2025

The threat for thunderstorms and precipitation over the next 36
hours are the main forecast issues. The upper level disturbance
over northwestern Colorado (mentioned above) has already begun
to initiate convection across the Cheyenne Ridge and a broad
area of agitated CU over the Palmer Divide is a strong
indication of likely storm development shortly. With surface
heating and a very weakly capped environment in place,
thunderstorms continue to develop from the panhandle into
northwestern portions of the forecast area. Looking at the
latest CAMS, believe the convection across the northwest will be
short lived with the main show developing over northeastern
Colorado and lifting into SW Nebraska shortly. Decent mid level
shear and robust mid level lapse rates will favor large hail as
the main severe threat primarily over southwestern Nebraska. As
activity tracks east into portions of central Nebraska, the
severe threat should wane. This is due to cooler temperatures
and residual mid level cloud cover from this afternoon's general
thunderstorm activity. As stated above, believe the greatest
threat for severe storms will be over far SW Nebraska with a
window from 23z to 03z this evening. Later tonight, a secondary
disturbance will track across Colorado and southern Wyoming,
approaching the forecast area late tonight. This disturbance
will lead to another round of thunderstorms overnight tonight
and Sunday morning. Severe parameters appear to be most
favorable off to the south of the area, however favorable lift
will remain across the southern half of the forecast area Sunday
with precipitation chances continued from the previous
forecast.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 308 PM CDT Sat Aug 9 2025

A more benign weather pattern will set up beginning Monday as
high pressure aloft builds into the southern Rockies. Weak mid
level flow will develop across the central plains with the best
mid level flow well off to the north of the area. This will lead
to dry conditions and readings warming into the 90s by midweek.
The latest EC ensemble forecast has no QPF across the area from
Sunday night through Friday lending additional forecast
confidence to a dry NBM forecast. Ridging aloft will begin to
break down late next week as a trough of low pressure deepens
along the Pacific Coast. This will lead to an increased threat
for precipitation across mainly the western half of the forecast
area.

.AVIATION /12Z TAFS THROUGH 12Z SUNDAY/...
Issued at 1215 PM CDT Sat Aug 9 2025

For the KVTN terminal: There will be a threat for isolated
thunderstorms in the vicinity of the terminal through 19z this
afternoon. Otherwise, expect scattered to broken ceilings around
20000 FT AGL over the next 24 hours. Winds will be variable at
under 10 KTS. For the KLBF terminal: Showers with embedded
thunderstorms may impact the terminal through 20z this
afternoon. The threat for storms will then increase once again
this evening from 00z to 06z Sunday. Some stronger storms may
produce gusts up to 40 KTS during this time period. Overnight
into Sunday morning, expect broken ceilings ranging from 8000 to
10000 FT AGL.
