It got a little muggy today as temperatures climbed into the mid to upper 80s under mostly cloudy skies. Humidity hovered around 50-60%, bringing our heat index up to 90 degrees. There have been a few scattered showers popping up to our west and north, though nothing intense. It should be another relatively quiet night in the District before the chance for rain and storms picks up on Wednesday.

Through Tonight: The chance of rain remains low (10%) across the region. Any rain showers that do form will be small and short-lived. Lows should bottom out in the low 70s this evening. Expect winds out of the south at 5 to 10 mph.

Tomorrow (Wednesday):  Highs on Wednesday will reach the low to mid 90s. This combined with high humidity will push the heat index to close to 100.  It could be a stormy evening in the D.C. region on Wednesday, and some storms could be locally severe, though we’re not expecting to see any widespread severe weather. We have a 50% chance of rain and thunderstorms on Wednesday, mainly for the late afternoon and early evening hours. Winds will be out of the southwest around 10 mph.

Typhoon Matmo lashes Taiwan

Typhoon-chaser James Reynolds is in Taiwan this week as Typhoon Matmo is making landfall. He captured these clips that show how powerful a category 2 typhoon can be. Winds whip through palm trees and rain falls horizontally.  Late in the video (0:55), a man walks across the shot in what appears to be a motorbike helmet. At least he was taking precautions, I guess!
