Area Forecast Discussion National Weather Service Spokane WA 1033 PM PDT Sun Jun 15 2025
KEY MESSAGES
- Elevated fire weather conditions through Wednesday.
- Cooler with increasing precipitation chances Friday through the weekend.
SYNOPSIS
Warmer temperatures into Monday before an increasing risk for elevated fire weather conditions from gusty winds through the middle of this week. Cooler temperatures and chances for showers increase late week.
DISCUSSION
Evening update to issue a Red Flag Warning for eastern Chelan county and Douglas county for Monday afternoon through Monday evening. The combination of dry conditions (relative humidity values dropping 10-20 percent) with breezy/gusty winds (15-25 mph and gusts up to 35 mph) will elevate fire weather concerns and could lead to rapidly spreading of fires should any ignite or already be burning. /Dewey
Previous Discussion (issued 354 PM PDT Sun June 15)...
Today through Sunday: Today is mild and very dry thanks to a shortwave ridge in place. Highs will peak in the 70s and 80s with relative humidities in the teens. There is a 10-15% chance of showers north of Highway 20 this afternoon in WA with terrain forcing. Monday will be dry, warm, and breezy as a wave crosses the Cascades in the afternoon. Temps will reach into the 80s with westerly winds around 10-20 mph gusting up to 30 mph. Debated red flag warnings for portions of central Washington (Wenatchee area, Waterville Plateau, and the western Columbia Basin) but the humidity/wind combo will have an hour or so mismatch. Southwest flow will increase ahead of a shortwave Tuesday night bringing small precip chances (15%) to the Cascade crest. The wave will pass through Wednesday bringing more breezy west winds. Wednesday has potential for some areas of central Washington to meet red flag conditions but PWATs will be a bit higher around 80-100% of normal so humidities are marginal. The deeper trough off the coast will slowly drift east late this week bringing cooler temperatures in the 60s-70s and chances for much needed rain to the INW. There is a 10- 30% chance of 0.25+" of rain in central WA, a 30-60% chance for eastern WA, and 60-80% chance for north Idaho from 5am Friday-5am Monday. The chances generally increase the more north and east you are. DB
