It was a very cool morning with temperatures in the 40s in the suburbs,  50s in the city and by the water.  High pressure will keep skies mostly clear. The air is dry and will warm up this afternoon into the lower 70s.  The cold front that dropped through predawn yesterday has stalled in the southeastern U.S.  Low pressure is developing along the front and will ride up the coast.

This Afternoon

This is our only hope for rain this week.  Clouds will increase tomorrow and rain showers will be possible by the late evening hours.  Much of the rain Wednesday night and Thursday will be along and east of I-95.  There is a 50% chance of rain for you there.  But, even northwestern suburbs have a 20% chance of getting some relief from the dry month we've had so far.  The deficit at Reagan National for September is now up to 2.25" and at Dulles it is 2.66"  Rainfall amounts will likely stay below 1/4"  but southern Maryland could get locally heavier amounts up to 1".
