453 FXUS66 KOTX 011106 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 406 AM PDT Sun Jun 1 2025 .KEY MESSAGES... - Elevated fire weather risk Sunday afternoon. - Dry weather pattern continues through next week. && .SYNOPSIS... Very dry conditions and continued breezy winds on Sunday will keep fire weather conditions elevated. Temperatures will remain near to above average for Sunday through much of next week. && .DISCUSSION... Sunday: Following Saturday`s cold front, temperatures on Sunday will feel much cooler with highs in the 70s to low 80s. Winds will shift to the west and north and become breezy through the Okanogan Valley, Cascade gaps, and western Columbia Basin. Despite temperatures being lower, much drier air behind the front will contribute to low relative humidity values in the teens to low 20s Sunday afternoon. This will keep fire weather conditions elevated through the afternoon. As the upper level trough moves across the region, models are showing enough moisture and instability across the North Cascades/Pasayten Wilderness to support a 15 to 20 percent chance of showers. Instability will be rather weak, but an isolated cell strong enough for a couple strikes of lightning is not out of question. Monday through Saturday: Going into the work week, a strengthening ridge offshore and a broad upper level trough from the northern Rockies to the northern Plains will keep the Inland Northwest under northwest flow flow through the week. Clear skies Monday morning and then again Tuesday morning will allow for strong radiational cooling with the northern valleys cooling into the upper 30s overnight. The NBM is giving the northeast valleys a 20-40 percent chance for temps of 37F or below. Weather looks to be generally quiet for the week with temperatures gradually warming. Embedded waves in the northwest flow will bring occasional shower chances across north Idaho along the Idaho/Montana border with widespread afternoon breezy winds. Winds on Friday are beginning to stick out as the next period to monitor with the NBM showing a 30 to 60 percent chance for wind gusts above 40 MPH across central Washington. /vmt && .AVIATION... 12Z TAFS: VFR conditions are expected to continue through the TAF period. Breezy winds will develop again this afternoon over Central Washington with sustained speeds between 10 to 20 knots and gusts 20 to 30 knots (KEAT, KEPH, KMWH, KOMK). FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence in VFR conditions.
