DISCUSSION. A Canadian “cool” front has pushed across the Continental Divide into western Montana this afternoon. Light (10-15 mph) north-northeast winds have developed across western Montana behind the frontal passage. The bulk of shower activity has shifted south and east along the Continental Divide in southwest Montana. The heaviest precipitation earlier this morning was observed in eastern portions of Glacier National Park and the Flathead National Forest, where around half an inch of precipitation fell. Skies will quickly clear out later this evening and overnight, as high pressure begins to build into the Northern Rockies.

Warm and dry weather returns across the Northern Rockies Monday, as high pressure amplifies across the region. High temperatures will soar into the 80s across western Montana valleys and into the 90s and low 100s across lower elevations of north central Idaho. A plume of mid to upper level Pacific moisture embedded within southwesterly flow will move across central Idaho and southwest Montana Tuesday afternoon. Marginal instability and lift will allow for high based isolated thunderstorms to developing during the late afternoon and evening hours.

Model ensemble guidance continues to depict a high amplitude blocking pattern across the western U.S. Thursday through next weekend. The blocking high has trended further north and east the last few runs. Recent model ensemble guidance suggests the center of the high may set up across northwest Montana, eastern Washington, or southern Canada. If this solution verifies, near record to record high temperatures will occur, particularly across north central Idaho. /Lukinbeal

AVIATION. A Canadian cold front has pushed across the Continental Divide into western Montana this afternoon, with light (5-10 kt) north- northeast winds expected to continue through the evening hours. A modest N-S oriented pressure gradient across Lemhi County Idaho will maintain frequent 20-25 knot wind gusts through at least 21/0400Z, with impacts expected at KSMN. The bulk of shower activity associated with the frontal passage has shifted south and east along the Continental Divide in southwest Montana. Skies will quickly clear out later this evening and overnight as high pressure begins to build into the Northern Rockies. /Lukinbeal
