With an extreme heat watch over much of the central and northeast U.S., including temperatures reaching near 100 F (see below), it is good to know that the weather over the Northwest will be near perfect over the holiday weekend.
Temperatures will rise into the mid-70s in Seattle on Friday through Sunday, while temperatures in eastern Washington will reach about 90F.
No worries about precipitation on July 4th, as illustrated by 3-h precipitation totals ending 11 PM that day (below).
Obscuring clouds on Independence Day? Here is the cloud prediction for 5 PM Saturday. Mostly clearly, except for high terrain in the Olympics.
To make things even better, the cool/wet conditions this week have made regional fuels less flammable, reducing fire risk this weekend (when all kinds of crazy fireworks activity will occur). See the predicted ERC and Fuel Moisture values below. There are no reds (serious risk) and only some marginal values (orange).
But please be careful.
I rather like the noise for a few hours on the 4th, after all this one will be our 250th celebration and even our first one in 1777 was reported in the larger cities to be very noisy with cannons, gunshots and fireworks. A cloud layer overhead would help reflect the sound back to ground level but that's not in the forecast. Just don't want to hear of anyone's home or business to burning down.
ReplyDeleteOn the 5th I will be looking forward to reading Cliff's hourly graph on area PM2.5.
How about the 850,000 fireworks they are planning on blowing up just around the Capitol?
DeleteUtterly stupid. It should be cancelled immediately.
I have to wonder how poor the air quality in Washington DC was in the hours immediatly following that record breaking fireworks display. From what I saw on the Watch Duty app, air quality along the Grays Harbor Coast was in the 150s and 160s following the fireworks displays.
DeleteIt's been raining for three hours in whatcom County, is the suffocating drought now over?
ReplyDeleteIt seems that the start of this summer and forecasts up to mid July are cooler and more moist than recent years. How does this compare with the El Nino predictions of a warmer than usual summer in the Pacific NW? Are we just waiting for a warmup in August?
ReplyDeleteEl Nino has a very minimal effect on our summer weather. We could easily end up wetter than normal.
