After the Fall


Breezy, chilly. After yesterday's strong cold frontal passage, temperatures in the Washington metro area struggled to reach the mid 60s this afternoon. Under some puffy instability cumulus clouds and a brisk northwesterly breeze, the official high temperature is likely to be the coolest since the 64° over 4 months ago on May 19. The next system moving in from the Great Lakes this weekend will have less moisture to work with, and indications from today's latest models are that the showers associated with it are likely to hold off until Saturday night.

Tonight and Tomorrow

Continued cool. Winds will diminish tonight, and lows will be near 50° downtown to the lower 40s in the cooler 'burbs. Tomorrow will see some increasing clouds in the afternoon, but only a 20% chance of showers before evening.

Tropical Topics

Tropical Storm Isaac has been moving a bit more west than expected in the central Atlantic, but it is still predicted to track well east of Bermuda, brushing by Newfoundland early next week. Its 45 mph peak winds increased to 60 mph this afternon, and strengthening to a hurricane is possible this weekend.

Climate Corner

The Weather Channel's new weekly "Climate Code" program, which premieres Sunday at 5, was previewed in the hometown Atlanta Journal-Constitution yesterday with an article, "Weather Channel ready to take heat on global warming" (requires minimally annoying registration). The associated broadband channel, One Degree, was previewed in Mediaweek.
