Fire Weather Outlook
— Day 2
Synopsis
A corridor of dry southwest flow southeast of the broader upper-level trough over the Northwest will present fire weather concerns where receptive fuels exist across portions of central and northeastern WY, central and southern MT, and the low elevations of far southwestern SD on Day 2/Wednesday. A persistent deep layer of southwest flow amid lee surface troughing over the central/northern High Plains will support southwest surface winds of 15-20 mph coincident with afternoon RHs as low as 10% within portions of the drawn area. Light rainfall prior to the onset of dry and windy conditions is not anticipated to significantly impact fuels receptivity.
Strong southwest winds of 15-25 mph and low daytime RH will also occur from southern NV into western UT on Day 3/Wednesday. However, recent more substantial rainfall has muted fuel receptivity across this area, precluding any drawn areas.
