DISCUSSION
Breezy afternoons, mainly dry conditions, and smoky skies will dominate the weather pattern through Monday. An exception will be tomorrow as a weak wave will provide the lift for a mix of wet and dry thunderstorms in the S. Bitterroot Valley, Lemhi County, ID, and southwest MT which will lead to concerns for a critical fire weather day in those locations. Any storms will be capable of gusty and erratic outflow winds.
Tuesday a stronger wave associated with some Pacific moisture will transit the Canadian border bringing showers and thunderstorms mainly to northwest Montana and the Continental Divide. Slightly cooler temperatures will result from cloud cover.
By Thursday, the model consensus is increasing temperatures with a reemergence of the 4-corners high pressure. A deepening Alaskan trough on the 2-3 Aug will force the axis of the ridge to the east. The question then becomes, will the ridge hold and the Northern Rockies experiences very warm temperatures with increasing instability or a complete ridge breakdown? Future forecasts will answer this question.
AVIATION
Breezy winds out of the west will develop this afternoon and evening and will be the main weather feature at all terminals today. Smoke from local and regional wildfires will degrade visibility at times throughout the Northern Rockies today and tonight.
