Latest NH poll (taken after the debate) shows Trump leading by 2 points. That's a 12-point swing from December when Biden was leading by 10 points.

There's already a flood watch for the local river 4 miles south just because of forecasted rainfall! Though it's not particularly wet at my place part of the river basin got up to 1.50" of rain on Friday. DVN AFD sounds bullish, but we'll see....

I'm hoping for 2" this week before a possible dryer pattern.
The back end of this looks very different than 2010 though. That heat wave clearly crashed from the east as the ridge retrograded and troughing remained in place across the middle of the country. I don't think that is going to happen this time. This looks more traditional with weak troughing returning from the west as the ridge gets nudged east.
EPS says a run-of-the-mill and short heat wave for Seattle. This would not even reach the 2010 level which had 3 days of 90+ at SEA. Assuming it has a cool bias here then maybe you can assume 3 days of 90+.
In 2010 the peak was 90, 95, 93. This doesn't look much different.
