Day 3-8 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0437 PM CDT Sun Aug 25 2024

Valid 271200Z - 021200Z

A robust midlevel trough/low will advance eastward across the
Northwest on Day 3/Tuesday. A related belt of strong deep-layer
west-southwesterly flow will cross the Cascades, promoting strong
downslope winds into the Columbia Basin. These winds, coupled with
downslope-induced warming/drying, will favor elevated to locally
critical fire-weather conditions during the afternoon and evening.
40-percent Critical probabilities have been maintained with this
outlook, though if fuels trend drier than currently anticipated, a
Critical area could eventually be needed. 

On Day 4/Wednesday, the midlevel low will continue eastward, with
associated strong post-frontal surface winds overspreading the
northern Rockies and adjacent High Plains. While this will favor
some increase in fire-weather potential, preceding rainfall and a
potentially limited overlap with low RH casts uncertainty on the
overall risk -- precluding Critical probabilities at this time.
Breezy post-frontal winds will continue across the northern High
Plains into Day 5/Thursday, with similar uncertainties to the day
prior.

Thereafter, an expansive large-scale ridge will build over the West,
resulting in a warming/drying trend and a fairly weak surface
pressure gradient until around Day 8/Sunday.
