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 && .AVIATION... A ridge of high pressure today will keep winds light and mostly clear VFR skies in place through tonight. DMH && .PIH WATCHES/WARNINGS/ADVISORIES... None. && $$ ]]>
