  Tuesday, with increasing chances for late day showers and
  thunderstorms for Wednesday and Thursday.

.SHORT TERM /THROUGH SATURDAY/...
Issued at 151 PM MDT Thu Jun 5 2025

Ongoing showers and thunderstorms once again across the region
this afternoon, but with widespread cloud cover and cooler
temperatures alongside morning activity hindering the
environment, stronger weather has not bee able to develop. Not
ruling out the possibility of strong to possibly severe
thunderstorms, but the risk is looking more and more unlikely as
the better ingredients lie just to our south in Colorado. High
res guidance suggests we should continue to see activity through
the early evening hours before it should wane. However,
hazardous conditions still remain as the abundant rainfall we've
been seeing recently could lead to localized flooding. Any
locations that can see multiple decently potent thunderstorms
could need at least a flood advisory. Otherwise, a few
overnight showers or some storms could be possible, but should
mostly be relegated to the western portion of the CWA in the
intermountain areas. Also overnight, cloud decks should lower
once again, and areas of of low clouds to patchy fog for the
Laramie Summit and eastwards through the NE Panhandle could be
possible.

Tomorrow, another round of showers and thunderstorms is expected
with a marginal risk once again mostly relegated to extreme
southeastern Wyoming as widespread severe ingredients will be
too limited thanks to ongoing cloud cover and early
precipitation activity. But with a modest amount of instability
alongside some shear, a stronger storm or two can't be ruled
out. One again though widespread precipitation activity and
storms training over each other could bring more moderate to
heavy rainfall, so look for a flood risk with this activity to
be possible. While widespread precipitation totals are expected
to average around a tenth to a half of an inch, localized
amounts exceeding 1-2 inches could be possible. Otherwise
Friday is expected to be our final cool day with highs in the
60's under cloud cover and precipitation, giving way to warmer
temperatures over the weekend as more summer-like conditions
return.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Issued at 151 PM MDT Thu Jun 5 2025

Saturday...Northwest flow aloft prevails, and with some drying noted
at low and mid levels, no precipitation is expected. 700 mb
temperatures near 10 Celsius will yield maximum temperatures from
the lower 70s to lower 80s.

Sunday...The flow aloft turns north northwest and it looks slightly
cooler in the wake of a passing cold front. Looks like enough low
and mid level moisture for isolated to widely scattered
thunderstorms over and near the Snowy and southern Laramie Ranges
and the Laramie Valley.

Monday...Dry again as the low and mid levels dry out under north
northwest flow aloft.

Tuesday...As ridging aloft moves overhead, and 700 mb temperatures
rise to near 12 Celsius, maximum temperatures will rise into the
upper 70s to mid 80s. Isolated late day thunderstorms will be
possible over the Snowy and southern Laramie Ranges and the Laramie
Valley.

Wednesday-Thursday...Zonal flow aloft prevails, with weak shortwave
troughs aloft in the flow and adequate low and mid level moisture to
produce scattered late day showers and thunderstorms each day.
Temperatures will remain warm based on the projected 700 mb
temperatures.

.AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
Issued at 1137 AM MDT Fri Jun 6 2025

The first round of showers has cleared WY terminals, but will
bring VIS reductions due to rainfall across the central/southern
Nebraska panhandle through early afternoon. Then, attention
shifts back to additional rounds of showers and thunderstorms
developing over Wyoming early this afternoon and moving east
into Nebraska through mid evening or so. Thunderstorms will have
the potential to bring gusty winds, hail, and brief IFR VIS in
heavy rainfall. Expect activity to wind down near WY terminals
by around 01z, and by around 04z near Nebraska terminals. Skies
will gradually clear overnight with a dry, breezy day expected
Saturday.
