.SYNOPSIS...
Issued at 311 PM CDT Fri Aug 28 2026
The H5 pattern this morning had an area of high pressure
located over western New Mexico. Ridging extended north northeast of
this feature into eastern portions of the NW Territories of Canada.
West of the ridge, a strong shortwave was located over central
Alberta with another shortwave located over far southern portions of
the Alaska Panhandle. East of the ridge, closed low pressure was
located over southern portions of Hudson Bay. A trough of low
pressure extended south of this low into the Mid-Atlantic and upper
Ohio Valley. Southwesterly flow aloft extended from the western
Dakotas and northwestern Nebraska southwest to California and
Oregon. Within this flow, embedded disturbances were noted from
Nevada into Idaho. The disturbances have moved northeast into
Wyoming per current WV imagery. Across western and north central
Nebraska this afternoon skies were clear to mostly clear and 2 PM
CDT temperatures ranged from 83 degrees at Broken Bow to 93 degrees
in Ogallala.

.SHORT TERM /THROUGH SATURDAY NIGHT/...
Issued at 311 PM CDT Fri Aug 28 2026
Embedded disturbances will ride northeast across Wyoming and
northern Colorado, approaching eastern Wyoming and north central
Colorado late this afternoon, initiating convection along the
front ranges of southeastern Wyoming and northern Colorado. This
activity will ride east into the evening hours with the best
chances for precipitation mainly along and west of highway 83.
The loss of surface heating and associated instability will
decrease heading east across the eastern half of the forecast
area. With that in mind, have favored highest pops over the far
western forecast area, gradually decreasing them from west to
east to the highway 83 corridor. This is in agreement with the
latest CAMS including the 12z NAM12 and WARW solns and the 17z
HRRR. A second area of convection, which originates over South
Dakota, may impact far northeastern portions of the forecast
area late this evening into the overnight hours. As for the
severe threat, feel the initial mode in the west will be large
hail and gusty winds given the fairly steep mid level lapse
rates. DCAPE is favorable for gusty winds later this evening in
the east. On Saturday, H5 high pressure will transition east,
approaching the Texas Panhandle early Saturday afternoon. Broad
west southwest flow aloft will develop upstream from the ridge
to a deepening trough of low pressure anchored over the Pacific
NW Coast. Saturday will be very warm across the forecast area
with H85 temperatures reaching 31C at 21z for KLBF (12Z NAM
soln). Readings reach around 33z for KIML. That being said
forecast highs in the upper 90s to hear 100 for SW Nebraska
appears on track. As the Pacific NW trough approaches northern
Idaho late Saturday, ridging across the central plains will be
suppressed south, leading to west southwesterly flow aloft.
Convection is expected to fire over the Cheyenne Ridge and
northeastern Colorado Saturday afternoon, then lift east
northeast into the forecast area Saturday evening. ATTM the
greatest risk for severe storms appears to be over western and
northwestern portions of the forecast area per the latest
SWODY2. However, based on the latest NAM12 soln favorable DCAPE
and shear extends further south into SW Nebraska Saturday
evening. The 12z HRRR soln this morning is hinting at bowing
segments along the I-80 corridor Saturday evening. That being
said, wouldn`t be surprised if the marginal risk is extended
further south covering more of southwestern Nebraska
Saturday/Saturday night.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 311 PM CDT Fri Aug 28 2026
Upper level low pressure will transition east along the
Montana/Canadian border Sunday. The severe threat should shift
north into the western and central Dakotas Sunday night.
However, we may see a strong to severe storm along a trailing
frontal boundary. This feature will track across the forecast
area Sunday night so am expecting a "late show" across the
forecast area with convection during the late evening to
overnight hours. Beyond Sunday, upper level high pressure will
transition east from the Arklatex into the Tennessee Valley.
Gulf moisture on the back side to the high will lift from the
southern plains into eastern Kansas and the lower Missouri
Valley. The latest mid model solns indicate a drier airmass
across central and western Nebraska, leading to lower
precipitation chances across the area. This drier trend will
begin on Tuesday and continue into Friday next week. After highs
in the 80s to near 90 for Monday and Tuesday, above normal
temperatures will arrive Wednesday continuing through Friday
with highs generally in the lower to mid 90s.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1228 PM CDT Fri Aug 28 2026
Cloud cover will gradually increase late this afternoon into the
evening hours as isolated thunderstorms across the Nebraska
Panhandle, drift east into western Nebraska. The current CAMS,
have trended downward with thunderstorm coverage, especially
along and east of a line from KVTN to KLBF. That being said,
will handle the thunder mention with a VCTS group and broken
ceilings at 12000 FT AGL from 01z to 05z this evening. Low
level wind shear will be possible at the KLBF terminal after 05z
tonight, continuing through 12z Saturday morning.
