The past few days have been just about perfect as far as the end of July is concerned. Low humidity levels and below average temperatures have made for very comfortable conditions. One thing has been missing now for a while through the majority of the D.C. area... rain.
Taking a look at some of the area climate reports, you wouldn't think the region has been hurting for precipitation. Reagan National has recorded over 4.5 inches of rain for the month of July. Even the drought monitor shows our area is doing well for precipitation. But taking a closer look, the area has been dry for the second half of the month.
Since July 16, Reagan National has only recorded 0.11" of rain, Dulles 0.13" of rain, and BWI Marshall has seen the most at 0.23" of rain. With the pattern changing as we speak, this should change over the next few days.
- WPC Precipitation Outlook through Sunday evening
A frontal boundary south of the D.C. area is expected to push north along the east coast, which will help become the focus for showers and a few storms to ride along. The heaviest rain is expected to remain south and east of D.C., with upwards of 4 inches of rain possible over eastern portions of North Carolina and over 2 inches possible towards the Delmarva Peninsula.
Don't expect the weekend to be a complete washout just yet. Not all modeling is in agreement, but as of now, the highest likelihood for steady rain appears to be Friday night into Saturday morning.
Breaks in the overcast will be likely Saturday afternoon and through the day on Sunday. Temperatures will remain slightly below the average of 88 this weekend with highs only expected to reach the low to mid 80s.
