Enough sun peeked through the clouds to make it a pretty uncomfortable afternoon out there in combo with high humidity levels. D.C. heat indices snuck up to nearly 100 at times thanks to dew points as high as 77 degrees! It should remain mostly quiet through sunset, but some storms to the west are worth watching.
Through Tonight: Partly to mostly cloudy skies continue into the evening, with just a slight chance of a shower or thunderstorm in a few spots. However, we’ll want to keep at least half an eye out for storms to the west, northwest and southwest, as they may make it into parts of the area by late evening or the overnight period. A general 40%-50% chance of showers and storms should suffice given uncertainty about how far east storms will get before weakening. Lows are mainly from near 70 to the mid-70s.
Tomorrow (Thursday): Another mostly cloudy day is ahead, and showers/thunderstorms appear to want to be at least somewhat widespread (60% chance of rain) as a front moves through. A few of those storms could be strong to severe, though it does not look like a widespread severe weather event. Highs again range from the mid-80s to near 90, mostly dependent on how much cloudiness vs. sun we see.
Hottest place on earth: 100 years ago today, an observer at Greenland Ranch in Death Valley, California recorded an astonishing 134 degrees. This is considered the most reliable high temperature record on Earth. Temperatures have not reached or topped 130 degrees there since 1913. Of course, just recently Death Valley made it to 129 degrees — the highest on record there in June.
Pollen update: Tree, grass and weed pollens continue to be low. Mold spores are HIGH since it’s always humid these days.
