FXUS66 KOTX 021059 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 359 AM PDT Fri May 2 2025 .KEY MESSAGES... -High temperatures 10 to 20 degrees above normal Friday. Minor HeatRisk. -Cooler temperatures, showers, and breezy winds Saturday and Sunday. -Temperatures trending warmer next week. && .SYNOPSIS... Temperatures will remain warm and dry for today with a minor risk for heat-related illnesses for those extremely sensitive to heat. Cooler temperatures and showery conditions are anticipated for Saturday and Sunday. Windy conditions are expected through the Cascade gaps on Saturday and the Okanogan Valley on Sunday. Temperatures trend warmer through the middle of next week. && .DISCUSSION... Today through Saturday: Today will be the warmest day of the start of the weekend. Temperatures will climb into the upper 70s and low 80s as the effects of the continuing ridge. Some forecast ensembles are slightly cooler, suggesting highs in the upper 70s. Either way, temperatures will remain above normal. The ridge begins to breakdown late Friday afternoon with a incoming cold front pressing into the Cascades. It is a fairly dry system keeping precip amounts to a few hundredths over the Basin and a couple of tenths over the higher terrain through Saturday. Highs will be noticeable different though with a range of 60s to low 70s expected. Overnight lows will dip into the 30s and low 40s. Sunday through Friday: By Sunday, the Inland Northwest will be in a weak pressure pattern, supporting scattered mountain showers and breezy winds. Temperatures will rebound into the 70s and low 80s Monday through as another ridge builds. The ridge is expected to weaken by Wednesday evening as a low pressure system from the Gulf of Alaska approaches. The models are trending drier as the system is expecting to stall and weaken before moving through the Pacific Northwest. It is limiting the confidence in precip for the midweek. The system will usher in a cooler Southwest flow pattern allowing for highs to moderate back into the upper 60s and 70s. Overnight lows will continue to be in the upper 30s and 40s. /JDC && .AVIATION... 12Z TAFS: There is high confidence for VFR conditions with light diurnally driven winds.
