Look for showers and thunderstorms, some with heavy downpours, through the afternoon and overnight hours. Highs should reach only the upper 70s.

After a delightful Saturday that warmed to the mid 80s and provided plenty of sunshine and very little humidity, today is suffering by comparison. While still comfortable, a retreating warm front and low pressure have conspired to produce showers and thunderstorms for much of the region. The system has the potential to bring even more rain overnight and throughout the day on Monday; highs tomorrow, like today, will rise only to the upper 70s. Thereafter, high pressure will return to D.C. providing mostly sunny late summer days with highs in the mid 80s.
NOTE: Yesterday's 86 degree high and 69 degree low at Reagan National added up to the coolest day of the month of August. The 78 degree average was not only the coolest, but the only reading that exactly hit the statistical norm for the date. All the other days this month soared well above their averages. Enjoy your Sunday.
