.SHORT TERM /THROUGH SATURDAY/...
Issued at 218 PM MDT Fri Jun 27 2025
A few thunderstorms are noted this afternoon across the Nebraska
Panhandle with scattered weak echoes further west into Wyoming.
Overall environmental analysis indicates instability is limited
to just the panhandle, with a much more prime environment for
severe potential just east of our CWA. With conditions unlikely
to strengthen over the next couple of hours, it`s doubtful
we`ll see much more than the activity already ongoing, perhaps a
few scattered showers or maybe another isolated storm or two,
but overall severe potential will be minimal at best and peaking
currently. That being said, our usual suspects of virga producing
some stronger to near severe winds could occur in Wyoming,
supported by inverted V soundings. Look out for brief periods of
strong breezes. Meanwhile further west dry conditions alongside
breezy winds and RH values into the low teens to single digits
are promoting critical fire weather conditions, with another
chance of this tomorrow though winds will be a bit tempered
compared to today.
Overnight precipitation and winds will wane. Into Saturday, a
cold front stalling out into our region will help be the focal
point for new shower and thunderstorm development, but once
again a lack of moisture will hinder any potential activity and
the marginal risk for stronger to severe thunderstorms has been
nearly removed from our area because of this. A similar setup to
today including gusty virga showers will once again be possible
though in an inverted V environment, with this lack of moisture
also fueling another potential red flag environment for a
smaller portion of Carbon County.

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Issued at 218 PM MDT Fri Jun 27 2025
Sunday...Somewhat cooler temperatures in the wake of a cold front
and with an increase in cloud cover. Looks like adequate low and mid
level moisture for scattered late day showers and thunderstorms,
mainly east of I-25.
Monday...Temperatures about the same as on Sunday, with low level
upslope east winds and 700 mb temperatures near 10 Celsius. Despite
adequate low and mid level moisture, we should see a decrease in
coverage of showers and thunderstorms due to ridging aloft.
Tuesday...A warming trend develops as 700 mb temperatures rise to
near 15 Celsius. Adequate moisture aloft for isolated late day
showers and thunderstorms, mainly east of I-25.
Wednesday...The warming trend continues as 700 mb temperatures reach
16 Celsius. Moisture looks similar to Tuesday, thus we anticipate
isolated late day showers and thunderstorms.
Thursday-Friday...Similar temperatures to Wednesday with 700 mb
temperatures near 16 Celsius. Adequate low and mid level moisture
again, thus isolated to scattered late day showers and thunderstorms
expected.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 541 PM MDT Fri Jun 27 2025
A few lingering showers will wane over the next few hours, but
may continue to bring brief gusty winds or a rumble of thunder
to terminals through about 02z. After that, a southerly low
level jet will increase in strength over the Nebraska panhandle,
bringing gusty southerly winds and/or significant LLWS to NE
terminals. Gusts may occasionally reach the ground, but when
surface winds are light, expect to find LLWS. This will weaken
early Saturday morning. Another round of isolated high-based
showers and thunderstorms is on track for Saturday afternoon. In
Wyoming, expect little to no rain, but these may bring strong
gusty winds. Brief downpours are possible at Nebraska terminals.
