The Elevated area was expanded slightly in portions of Colorado,

Wyoming, and Montana based on the latest high-resolution forecast

guidance. Isolated mixed wet/dry thunderstorms remain possible in

portions of far southern Nevada and Utah into northwest Arizona, but

uncertainty remains regarding thunderstorm development over

receptive fuels.

...Synopsis...

Upper-level ridging will continue to build across the western CONUS

as an upper low traverses the Canadian Prairies, permitting strong

northwesterly flow to overspread the northern Plains. Ahead of an

approaching cold front, daytime high temperatures will reach 90+

degrees F as RH values quickly decline to less than 20% and

west-northwesterly winds increase to 15-20 mph. The aforementioned

cold front will enter Montana sometime Day 2/Thursday afternoon,

though approximate timing is uncertain given varying model

solutions. As the front passes, winds will shift to broadly

northerly at 15-25 mph (gusts over 30 mph) for a couple of hours

while RH increases overnight. Elevated highlights have been

introduced across portions of the Colorado Plateau into the northern

Plains where ERCs will range from the 80-95th percentile, and NDVI

portrays a significant 30-day decrease in live green vegetation.

Prolonged above normal temperatures, a dry boundary layer, and

briefly breezy winds may encourage locally elevated fire conditions

to emerge across the California valleys and adjacent higher terrain

where widespread ERCs exceed the 90th percentile.
