Day 3-8 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0428 PM CDT Sun Aug 04 2024

Valid 061200Z - 121200Z

...Synopsis...
A mid to upper-level shortwave trough will traverse the Pacific
Northwest D3/Tuesday atop an upper ridge, while the ridge is shunted
south and slightly eastward. The aforementioned shortwave trough
will continue to progress eastward into the Great Plains
D4/Wednesday, with some narrow bands of modest mid-level flow
acco*panying it across the northern Great Basin and Rockies.
Generally, weaker flow is expected through most of the troposphere
after D4/Wednesday across much of the central and western CONUS
through D8/Sunday.

...Dry Thunderstorms...
Increasing mid-level ascent associated with a shortwave trough will
impact the northern and central Rockies D3/Tuesday. Sufficient
monsoonal moisture within and on the northern periphery of the upper
ridge, above drier boundary layer conditions, will continue to
support dry thunderstorm chances over receptive fuels from
southwestern MT, southeastward into WY, eastern UT, and
western/northwestern CO. PWATs are expected to fall across these
regions into D4/Wednesday, although the area of 10 percent Isolated
Dry Thunderstorms will beco*e more confined to western CO and
eastern UT by then as the main shortwave trough moves into the
Northern Great Plains.

...Dry and Windy...
Increasing west-northwesterly surface winds will develop
D4/Wednesday across the Upper Snake River Plain/southeast ID and
Wyoming Basin via a tightening surface pressure gradient, and
momentum transfer from aloft under a belt of relatively stronger
mid-level flow. While fuels should remain less receptive across
southeast ID during this time, hot and dry conditions will co*bine
with these breezier winds across southwest WY where they should
remain more receptive. A small 40 percent Critical area has been
introduced there.
