Our summer temperatures have very little variability dude, the amplitude of thermal anomalies is small. Opposite of winter. We don’t have the luxury of a cold Pacific Ocean immediately upstream. As soon as the Canadian cold pool dissipates in June, there is no cool air source remaining to draw from, and most cold fronts either don’t make it here or end up being “dry fronts” warmed by solar heating by the time they arrive.

We're about 10 miles south of Winthrop, so OK on this one and looks like they just threw a *** ton of resources at it right off the bat since it was blowing towards the town and they knocked it out pretty good. Fingers crossed.

WBGT is replacing heat index for risk thresholds as it encompasses a more diverse parameter space. It’s likely to be what NWS uses heat advisories/warnings. It’s listed right below heat index here. https://www.weather.gov/safety/heat-tools

Didn't cherry pick, they aren't random. The options for maps on the HPRCC site are: last 7 days, 14 days, MTD, 30 days, 60 days, etc. None of them show your region really torching. Crazy that a +1.4 anomaly is top 10 warm there. It would have to be at least +3 here. I see IAD got a couple inches yesterday! Puts them wetter than normal for June.

Justin is right that you cherry-pick a few random snippets of time to muddy the waters. IAD is running a +1.4 departure for June (top-10 warmest on record) even with the recent cooler stretch because of how hot it was before that. April isn’t summer, that stuff is irrelevant. Since the dominant summer pattern established the theme has been one of overperforming temps, especially during the day.
