.KEY MESSAGES...

- Elevated to critical fire weather today, with isolated
  afternoon showers and thunderstorms.

- Hot and dry weather continues through Monday.

- A transition to a cooler and wetter pattern begins Tuesday and
  continues through at least Thursday.

&&

.UPDATE...
Issued at 1226 PM MDT Sat Jul 26 2025

Red Flag Warnings continue through 8pm MDT today due to a
combination of low RHs and gusty winds. No major changes to the
forecast today regarding these weather elements. Have updated the
low precipitation chances with latest model guidance. Still
expecting mostly virga, with an occasional light shower. Could
see a little lightning over northern Wyoming if a stronger cell
forms. Main hazard with any convection today continues to be
gusty outflow winds. The latest HRRR runs would suggest 30 to 40
mph gusts are most likely, but with the dry air in place, there
is potential for stronger gusts.

For fire weather tomorrow, winds do not look quite as strong during
the afternoon. The one place where 25+ mph wind gusts may occur
would be over eastern Sweetwater County (eastern fire zone 279).
Given the limited extent and lack of confidence in wind, will hold
off on extending any fire highlights for tomorrow. Overnight shift
can take one more look at winds for tomorrow. At the very
least, widespread elevated fire weather conditions will be in
place Sunday, with afternoon RHs in the single digits across
much of the area, with breezy winds 15 to 25 mph.

.DISCUSSION...
Issued at 252 AM MDT Sat Jul 26 2025

Climatologically, we are in the hottest time of the year. And the
next few days are no exception. Ridging will control the weather
over the Cowboy State and bring hot temperatures to much of the
area. Not record breaking heat, but highs in the 90s will be
fairly widespread in the lower elevations east of the Divide
with 80s in the lower elevations to the west. However,
temperatures are not the main concern of the forecast, fire
weather is.

All in all, today looks to be main day of concern. A weak shortwave
will move across the state today, helping to enhance mixing with
700 millibar winds anywhere from 20 to 30 knots expected to mix
to the surface, critical fire weather looks likely. This will
be mainly in the southwestern Wind Corridor from Rock Springs
through Casper where the chance of 3 hours of wind gusts past 25
mph is greater than 3 out of 5. So, we upgraded the Fire
Weather Watches to Warnings. We also gave thought to adding
Zone 283, which could see gusty wind this afternoon. The chance
here is only 1 out of 3 though, so we decided not to. Elsewhere,
elevated fire weather is likely given that humidity will be
very low, with most areas under 15 percent and many areas under
10 percent. There is another concern though. The shortwave could
produce isolated showers and thunderstorms this afternoon.
Given the lack of moisture, these would all be high based and
the chance at any point is less than 1 out of 5. These are also
impossible to pinpoint. So, we left continuity alone. Many of
these would not have any rain, only virga. However, given the
high bases of the convection and very large dew point
depressions, (over 60 degrees in many locations), any
thunderstorm, shower or even enhanced cumulus cloud could
produce strong wind gusts if it collapses.

The next question is, what about fire weather for tomorrow. It looks
more borderline. For one, there will be no shortwave to mix the
atmosphere and 700 millibar winds are 5 to 10 knots lighter. This is
especially the case in Natrona and Fremont Counties. For now, we
kept the warning for today but we may end up extending it out
through Sunday. This would be mainly for Sweetwater County though.
We will let the day shift or Saturday`s night shift take another
look at it before issuing. And with no shortwave, the chance of
convection will be near zero for most locations. The only place
would be the northern mountains, but even here the chance is
less than 1 out of 6.

Monday at this point looks like another hot and dry day, with the
same chance of isolated storms across the far north. Wind looks
lighter on this day, so the chance of critical fire weather
looks low (less than a 1 out of 4 chance) despite humidity
remaining low. This changes on Tuesday though. A cold front will
slide toward the area from the north. At the same time, a surge
on monsoonal moisture moves in from the south and west. The
result will be a much more moist atmosphere. Precipitable waters
will jump from 30 percent below normal to 150 percent above
normal for areas east of the Divide on Tuesday and most areas on
Wednesday. The result will be more cloud cover, cooler
temperatures, and an increased chance of showers and
thunderstorms through at least Thursday. At this point,
Wednesday looks to be the day of the most widespread showers and
storms. Pinpointing areas of the heaviest precipitation,
especially with convection, is very difficult this far out
though. However, confidence is high (around a 4 in 5 chance)
that will will transition into a wetter pattern starting on
Tuesday.

.AVIATION /00Z TAFS THROUGH 00Z MONDAY/...
Issued at 442 PM MDT Sat Jul 26 2025

Most areas remain VFR through the next 24 hours, with only high
clouds and light smoke from fires to the south. Showers and
thunderstorms continue over northern portions, with KWRL being
the most under threat with storms in the vicinity. These storms
are still expected to end/exit the area around 02Z. Winds will
remain light overnight. High clouds and light haze continue
tomorrow, with precipitation currently not expected at any
airport. Gusty winds will be limited to KCPR and KRKS in the
afternoon, with gusts right around 20kts.

Please see the Aviation Weather Center and/or CWSU ZDV and ZLC for
the latest information on smoke, icing, and turbulence
forecasts.

.FIRE WEATHER...
Issued at 252 AM MDT Sat Jul 26 2025

A combination of humidity falling into the single digits and a
gusty afternoon breeze will bring critical fire weather to
southern Lincoln, Sweetwater, southeastern Fremont and Natrona
Counties this afternoon. Elevated fire weather is likely for
other locations. Elevated to possible critical fire weather
continues on Sunday with some easing of conditions on Monday and
especially the middle of next week.

.RIW WATCHES/WARNINGS/ADVISORIES...
Red Flag Warning until 8 PM MDT this evening for WYZ277-279-
