One way to gauge how warm it’s been is how easily we keep hitting 90 or higher on days with lots of clouds. Today was another one of those occasions in D.C., and now our ninth 90+ in a row, going back to the end of last month. Looks like we’ll extend that streak to at least 10 without much problem tomorrow. After that, rain chances start to increase and temperatures hopefully decrease heading through the rest of the week.
Through Tonight: Skies are mostly to partly cloudy, and we may see an isolated shower or storm, particularly through the evening. Any spots that get rain might receive briefly heavy downpours, though most spots should stay dry. Overnight lows range from near 70 to the mid-70s.
Tomorrow (Thursday): We should see more plentiful sunshine tomorrow, at least during the first half of the day. That means temperatures are likely to get boosted a bit higher, and they’ll probably range from the low-to-mid 90s for highs. Storms may fire up during the afternoon near or just east of the mountains, but they’re likely to be scattered. However, some could be strong to isolated severe.
Tropics: Ernesto, now a weak tropical storm, is close to completing its journey across the Yucatan after making landfall as a Category 1 hurricane last night with sustained winds around 85 mph. It looks to briefly re-emerge over the southern Bay of Campeche, but should remain close enough to land not to strengthen much if at all. Another area of disturbed weather is several days east of the Caribbean islands and shows no real sign of imminent intensification. Finally, a large wave of low pressure is about to enter the Atlantic from Africa. Models are hinting that this system may develop.
Pollen update: Tree and grass pollen are both LOW. The weed count is LOW/MODERATE, and mold spores are MODERATE.
