probability of exceeding 0.50" of rainfall, which drops off
rapidly moving east, except around 35% chances in the Big Holes,
Tetons, and higher elevation areas surrounding Island Park. WPC is
maintaining the Marginal risk of Excessive Rainfall Monday for
the regions north of Sun Valley including Stanley and Challis.
There is still roughly a 15-30% chance of thunderstorms as well,
and thus those precipitation amounts could fluctuate with
localized convection. Snake Plain still looks windy Monday as
well, with NBM showing >30 mph across a large swath of the Upper
Snake Plain. Precipitation does continue into Monday night, and
lingers mainly across the Wyoming border Tuesday. Though, as ridge
begins to build on Tuesday, temperatures should start creeping
back up. Amplified ridge builds through the rest of the week,
though there are some cluster differences in where the ridge axis
sets up and how amplified it gets. Current NBM deterministic runs
put 80s back in lower elevations by Thursday, with more than a few
locations hitting 90 by Friday. NBM probabilistic values put a
>50% chance to hit at least 90 both days mainly west of American
Falls into the Eastern Magic Valley. DMH
