Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
1135 AM CDT Mon Jul 29 2024

Valid 291700Z - 301200Z

The previous forecast (see below) generally remains on track, with
no changes or additions made. A dry thunderstorm or two may traverse
southern Montana or northern Wyoming during the afternoon. However,
thunderstorm coverage is expected to be too sparse to warrant dry
thunderstorm highlights.

..Squitieri.. 07/29/2024

.PREV DISCUSSION... /ISSUED 0155 AM CDT Mon Jul 29 2024/

...Synopsis...
A broad large-scale trough will move slowly eastward across the
Northwest during the day, while an expansive upper ridge remains
centered over the south-central CONUS. Between these features,
moderate (around 30 kt) midlevel west-southwesterly flow will
persist across much of the Great Basin into the Northern Rockies and
adjacent High Plains.

...Northern Rockies/High Plains and Great Basin...
Deep boundary-layer mixing into the enhanced flow aloft from
southern NV into southern UT will favor 5-10 percent minimum RH and
15-20 mph sustained southwesterly surface winds. Given at least
modestly receptive fuels over the area, elevated fire-weather
conditions are expected during the afternoon.

Farther north, a modest pressure gradient along the western
periphery of a surface trough, coupled with the enhanced flow
through a diurnally deepening boundary layer, will yield around 20
mph sustained west-southwesterly surface winds across portions of
the northern Rockies/Intermountain West and adjacent High Plains.
Over southern ID and north-central MT, these breezy/gusty winds will
overlap 15-20 percent afternoon RH, resulting in elevated to spotty
critical fire-weather conditions.
