Area Forecast Discussion National Weather Service Spokane WA 532 AM PDT Mon Jul 18 2022 .SYNOPSIS... Today will be mild and breezy with widely scattered showers along the Canadian border. Tuesday through the weekend will be seasonably warm with afternoon temperatures in the 80s and 90s. Next week has the potential to be quite hot with widespread 90s and the Columbia Basin and Lewiston-Clarkston Valley near 100 degrees. && .DISCUSSION... Today: By sunrise, clusters of showers and thunderstorms will be exiting north Idaho as the center of a compact upper low pivots into northwest Montana. Scattered showers wrapping around the low are progged by the NAM, GFS, and several members of the HREF along the Canadian border from Okanogan county to far north Idaho this morning. A handful of lightning strikes will be possible from this activity around Republic and Omak early in the day before mid-level instability and deformation exits the region by mid morning. Breezy west or southwest winds will develop early in the day in response to the departing upper low. Sustained winds of 15 mph with gusts to 25 mph will be common from Wenatchee to Ritzville to Pullman and Spokane this morning into the mid afternoon. While humidity values today will not satisfy Red Flag criteria, new fires that ignite in dry grasses across the Columbia Basin and along the East Slopes of the Cascades will have the potential to spread today. High temperatures in north Idaho and the eastern third of Washington will mainly be in the mid to upper 70s today while readings in central Washington and the L-C Valley will be in the lower to mid 80s. Tonight and Tuesday: A warm high pressure ridge will quickly rebound over the Pacific Northwest tonight. Low temperatures tonight will be a few degrees below average...mainly in the 50s. Afternoon highs on Tuesday will rebound into the mid to upper 80s with low 90s in the Columbia Basin, along the East Slopes of the Cascades, and in the L-C Valley. /GKoch Wednesday through the Weekend: Ensembles continue to be in agreement that the pattern will stay warm and dry. Wednesday will remain the warmest day of the work week before cooling off a couple degrees as a trough moves into the PacNW on Thursday afternoon/evening. This next system appears to be dry at this time but we will keep an eye on introducing thunderstorms into the mountain forecast areas as we get closer. After the trough moves east on Saturday, another ridge is set to build beginning Sunday with ensembles hinting that it could continue to get stronger (meaning even hotter temperatures) for the middle to end of next week. /KM && .AVIATION... 12Z TAFS: Shower activity will decrease this morning over the Idaho Panhandle as low pressure moves eastward. Lingering bands of wrap around showers and embedded thunderstorms around Omak, Republic, and Grand Coulee will produce localized downpours, small hail, and lightning through 15z-17z before deformation aloft shears apart. Breezy west winds will occur through mid afternoon with gusts up to 20-25kts at Pullman, Spokane, and Wenatchee. Decreasing winds and clearing skies are expected this evening and overnight as high pressure returns. /GKoch && .PRELIMINARY POINT TEMPS/POPS...
