Area Forecast Discussion For Western SD and Northeastern WY
National Weather Service Rapid City SD
1103 AM MDT Tue Aug 9 2022

.DISCUSSION...(Today Through Monday)
Issued at 147 AM MDT Tue Aug 9 2022

Water vapor imagery depicts dry air over the northern Rockies and
northern plains, beneath a building ridge. A surface trough 
stretches over eastern MT/WY. Beneath clear skies, winds are 
southeasterly 5 to 10 kts, and temperatures are in the 60s and 
70s.

Hot and mostly dry weather will continue for the next few days, as 
the upper ridge builds. With the passage of daily shortwaves, cannot 
rule out an isolated shower/storm over some part of the area each 
day; however, most places will remain dry. Today, the surface trough 
and some weak shortwave energy may allow for an isolated storm or 
two, mainly over the Black Hills, or in south central SD (where CAPE 
is highest). However, any precipitation would have to overcome low-
level dry air. Similar conditions are expected for Wednesday, and so 
have added some slight chance PoPs over the Black Hills. Highs 
through Friday will be in the 90s and 100s.

Stronger shortwave energy will bring a slight cooldown (highs still 
in the upper 80s and 90s) this weekend, along with better chances 
for showers/storms.

.FIRE WEATHER...
Issued At 147 AM MDT Tue Aug 9 2022

Hot and dry weather continues. Minimum relative humidity will dip
into the teens and 20s today, driest across northeastern WY. 
However, winds will be relatively light. On Wednesday afternoon, 
relative humidity is expected to be around 15% across northeastern
WY and southwestern SD. Southeasterly winds will be breezy, but 
may still be too light to warrant headlines. Breezy and dry 
conditions are expected again on Thursday, but at this time it 
looks like the breeziest areas won't coincide with the driest.
