Today and Tomorrow:
Temperatures today should creep into the mid 80s around the District, to near 90 south of town. There is a slight risk of a few thunderstorms later this afternoon as daytime heating destabilizes the atmosphere.

Tomorrow, expect cloudier conditions than today as a weak mid and upper level impulse slides in from the west. There will be a slightly better chance of showers and thunderstorms than today.

Local Drought Expanding:
Since July 12, Reagan National Airport has reported only a Trace of rainfall, and our total monthly rainfall (1.33 inches) came on just four days during early June. Currently, rainfall deficits are running one to two inches below normal for the month from DC north and west. The exception is in Baltimore, where 1.8 inches of rain fell on July 10th during a severe thunderstorm.

Presently, nearly the entire Mid Atlantic is experiencing abnormally dry conditions, and the areas of moderate drought have expanded over the past few weeks.

While there is a chance of thunderstorms through this week, until we can get a large, persistent area of rainfall to sweep through the east coast, the developing drought conditions will get no better.
