Wednesday Morning Weather Update: Strong Thunderstorms This Afternoon
Today: Potential for severe weather today...especially this afternoon and evening around Spokane. Partly cloudy with isolated showers & t/storms this morning...partly cloudy into about mid-day, then we'll start to see some thunderstorms brewing and pushing west to east from the Cascades. The potential is there for strong thunderstorms to form which would include frequent lightning, hail, heavy downpours and gusty outflow winds. More thunderstorms could start as early as noon over the Cascades then push east and into the Spokane area as early as 2-3pm. The threat lasts until about 10pm tonight. High: 83°
Satellite and Radar: A large area of low pressure off the coast will move on shore today, that is the primary cause of these thunderstorms...that and the cold front that will push off from that low. The low will move across us overnight tonight and out of the area by Thursday afternoon allowing for clearing skies.
Flash Flood Watch: is in place over the Methow, Okanogan and Wenatchee Valleys and east slopes of the Cascades, basically the areas where fires have been burning, until 11:00pm tonight. The reason? Heavy rain from thunderstorms has a hard time absorbing into burned surfaces, therefore it runs off the surface and could cause flash floods and debris flow.
Red Flag Warning: is in place over the lower Columbia Basin until 11:00pm tonight for the threat of lightning causing new fires to start and gusting winds helping fires move and grow.
