Special Weather Statement - Downpours & Threat of Thunderstorms Expected Today

Effective:  6:05 AM
Expires: 6:15 PM

A moist and unstable air mass will result in bursts of heavy rain during the day today. These downpours could produce a quarter of an inch of rain in less than 30 minutes. There will also be a risk of thunderstorms this afternoon over the interior, or east of the Olympic range, but a lightning strike cannot be ruled out elsewhere. Any thunderstorms that do develop today will have the potential to produce torrential rainfall that could cause minor flooding. Gusty winds of 35 to 40 mph will also be a possibility with the thunderstorms. This will be a situation similar to that of Tuesday afternoon.

Thursday will be a transition day from mild, wet weather to drier and warmer conditions. High pressure aloft will build over the region Friday and continue through this weekend. Daytime temperatures are forecast to climb into the mid-70s to mid-80s over much of the area, but not as warm on the coast due to light onshore flow. Although the air mass will undergo drying during this period, it will still remain relatively moist near the surface. This will make it feel warmer than it actually is. If you are thinking about escaping the heat, please remember that area rivers are still too cold to swim in. They are also a bit swollen or running swift from recent rains. Be water safe and wear your life jacket.
