Area Forecast Discussion
National Weather Service Riverton WY
306 AM MDT Mon Aug 8 2022

.SHORT TERM...(Today through Tuesday)
Issued at 201 AM MDT Mon Aug 8 2022

Drier air has filtered into the region in the last 24 hours, as
high pressure built into the region. This drier air has limited
cloud and fog formation, with barely any clouds noted across the 
state this morning. This ridge of high pressure will hold tight on
the state during the next 36 hours, bringing nearly clear skies
and temperatures jumping back into the upper 80s and lower 90s.
With high pressure in the vicinity during the period, winds will
remain light, likely no higher than 10mph through Tuesday night. 

.LONG TERM...(Tuesday night through Sunday)
Issued at 201 AM MDT Mon Aug 8 2022

Very little change in the synoptic pattern is expected through the 
period with dominant ridging across the western US. Summertime heat 
with highs in the mid to upper 90s F east of the Divide are expected 
for Wednesday and Thursday. Temperatures then moderate Friday and 
beyond as monsoonal moisture will wrap around the ridge into WY, 
with multiple shots of rain and thunderstorms likely each 
afternoon/evening. This is in part due to weak shortwaves in the 
flow around the upper high. PWATs will be well above normal hovering 
around an inch each day. Weak winds aloft coupled with above average 
moisture will result in an increased risk for flooding concerns, 
especially in areas that see wetting rain day after day. The good 
news is this will put a damper on the fire weather threat for the 
time being. Areas in drought will also improve and some may even 
make it out of drought after the next week when all is said and 
done. Wind will remain benign by WY standards with gusts of 10 to 20 
mph each afternoon through the period.

.FIRE WEATHER...
Issued AT 201 AM MDT Mon Aug 8 2022

A warming and drying trend will continue through midweek as high 
pressure builds across the state. Humidity levels today and
Tuesday will fall below 25 percent for higher elevations and
10 to 15 percent for lower elevations. High pressure will keep
winds lower for most locations, keeping the overall fire threat
lower through midweek. Some shower activity will return Wednesday
into Thursday, bringing along moderating humidity levels.
