We've got another nice one ahead Saturday, featuring below average temperatures and minimal humidity, before summer starts creeping back into the region.
By Sunday, temperatures head for the mid- and upper 80s, and then near or above 90 is a good bet to start the workweek. Beyond that, into early August, we should continue to see at least tastes of the hot season.
One interesting aspect is that it's not a pattern that screams super high temperatures despite tending to favor temperatures not far from 90. There's actually a relatively big dip forecast in the jet stream nearby.
An unusually powerful high-pressure heat dome in the western and central U.S. will help overwhelm the jet stream dup by feeding hot air east toward us. While readings get modified on the journey, it's still hotter than you might expect looking at an upper-level pattern map.
Going into August, it looks like a similar setup across North America, so we'll probably tend to favor near to above average, though intermixed with cooler moments.
With 32 days at or above 90 this year so far, DC is running about 10 days above average to date and is a little past a week off the full-season average. For the last five days of July through the end of the hot season, DC averages about 2.5 weeks of 90-degree days.
