.SYNOPSIS...
Issued at 334 PM CDT Thu Jul 31 2025

H5 analysis this morning had a broad ridge of high
pressure, extending from southern Wyoming into western portions of
the NW Territories of Canada. East of this feature, closed low
pressure as located over Labrador Newfoundland with a broad trough
located over far eastern Canada into the Canadian Maritimes and
northern New England. High pressure was anchored over Florida, while
a closed low was located over the Gulf of Alaska. Northwesterly flow
extended east of the ridge from Montana toward Minnesota, Iowa and
Missouri. Within this flow, weak disturbances were noted. Radar
imagery across South Dakota, indicated a disturbance lifting east
across central South Dakota. At the surface, decent high pressure
was located over northern Minnesota. A frontal boundary extended
from western Texas, east northeast into the Mid Atlantic states. A
frontal boundary extended along the eastern slope of the Rockies
from New Mexico, north northwest into western Montana. Across
western and north central Nebraska this afternoon, winds were
generally from the east or east southeast and skies were mostly
cloudy. Temperatures as of 2 PM CDT ranged from 73 degrees at Broken
Bow to 80 degrees at Ogallala.

.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 334 PM CDT Thu Jul 31 2025

Surface high pressure will build south across Minnesota
tonight. This will allow surface winds across the area to retain
an easterly component overnight and, with abundant low level
moisture available, low clouds are expected to develop once
again later tonight. Looking at the SREF, statistical guidance
and near surface visby products from the HRRR and NAM12 solns,
not concerned about fog development tonight and will keep it out
of this afternoon`s forecast package. Late this afternoon into
the evening hours, we should see convective development along
the surface frontal boundary from the front range of Colorado,
north into eastern Wyoming. This activity will lift into the
panhandle this evening and should loose its severe potential as
it enters the eastern Panhandle and encounters a fairly stable
airmass. As for precipitation chances, best confidence for
measurable pcpn will be for areas generally along and west of
highway 61 from Merriman to Imperial. Did carry some low pops
east into the highway 83 corridor late this evening into the
overnight. There is some indication of a low level jet tonight,
the core of which lies between highway 83 and 61. As for the
severe threat, attm. not really concerned about large hail as
the steepest mid level lapse rates lie west of the forecast
area. A marginal wind threat and heavy rain are the main
concerns tonight. A similar setup for severe storms is expected
Friday, albeit, slightly farther east for the severe threat. The
frontal boundary, currently over eastern Wyoming will lift
east, stalling across the western Nebraska Panhandle Friday
afternoon. This slight shift in the thetae axis will facilitate
storm initiation possibly in the western panhandle Friday
afternoon. Once again, this activity will work east into the
eastern panhandle then western Nebraska into the late afternoon
and evening hours. Like tonight, the presence of a low level jet
Friday night, should allow convection to sustain itself into
the late evening hours as it reaches along and east of the
highway 83 corridor. Further east of this line, it will
encounter a stable airmass and will probably have a difficult
time persisting across central into eastern Nebraska. As for
temperatures Friday, we will see a slight warmup in the far west
as the frontal boundary is expected to reach the central
panhandle late in the day. Further east, clouds, abundant low
level moisture and the influence of high pressure to the east,
will hold highs in the 70s.

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 334 PM CDT Thu Jul 31 2025

Ridging across the western CONUS will begin to flatten
Saturday. This will allow warmer temperatures to transition into
central and western portions of the forecast area with highs in
the 80s Saturday and Sunday. We will still see some mid to
upper 70s in the east as troughing over eastern Canada and the
Great Lakes will be slow to move into the western Atlantic. With
the front now located across the western forecast area, and
lower amplitude flow off to the west, we will see an increased
threat for storms Saturday and Sunday across the area. Believe
the severe threat will encompass more of the forecast area
Saturday and this is supported by the latest SWODY3 from SPC.
The warm front will finally lift east of the forecast area
Monday, aided by a strong shortwave trough, crossing the
northern Rockies. This will probably lead to decreased chances
for precipitation and even warmer temperatures across the area.
By Tuesday, The latest NBM ensemble, with support from the GFS
MEX guidance indicates a return to 90s across a large portion of
the forecast area. This heat looks to persist well into the end
of next week with decreasing precipitation chances noted toward
the middle and end of next week.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...
Issued at 1211 PM CDT Thu Jul 31 2025

Skies will remain mostly cloudy this afternoon at both terminals
with ceilings in the 3000 to 4000 FT AGL range. Stratus will
develop late this evening and continue into the morning hours on
Friday. Ceilings will fall off to under 1000 FT AGL at the KLBF
terminal and 1500 FT AGL at the KVTN terminal. There is a threat
for thunderstorms later tonight in the vicinity of the KVTN
terminal which may temporarily raise ceilings to VFR. The main
threat for storms in the KVTN vicinity is in the 07z to 11z
range tonight.
