WEEKEND UPDATE: 8/18- 8/19

THE WEEKEND continues to look like a gem, but a period of steady rain looks likely, from later Sunday night, into Monday night. More later on this rain event.

A cold front moved through the region early Friday evening. Some strong to severe thunderstorms developed as a weak disturbance moved across MD and DE. All this activity, along with the cold front are now well offshore. A strong high pressure system building into the G/L and SE Canada, will bring a much cooler and dry air mass for today and tomorrow.

Saturday: We can expect M.Sunny and breezy conditions, with Highs of 75 to 80.

Tonight: Clear and crisp, with lows in the low to mid 50's in the suburbs, and near 60 in PHL.

Sunday: We start out M.Sunny and cool, but clouds will increase during the afternoon hours. Continued breezy with Highs in the mid to upper 70's.

A warm front approaching from the Southwest will setup a nice overrunning situation for later Sunday Night through Tuesday. I'll have more on this Sunday. It looks like a nice period of steady rain will settle in, for much of the Del. Valley, from later Sunday night into Monday Night. M.Cloudy and more showery conditions for Tuesday. It will also continue quite cool, during this timeframe.


Saturday AM: Surface map and composite.
