While sunshine prevailed in the morning, clouds will likely tip the weather scales this Mother's Day afternoon.  Look for highs today near 80, but it will be much cooler and wetter by Monday.

This Afternoon: Fair skies, Comfortably Warm

Highs: 75-80 | Wind: SW 5-10 mph

Tonight: Showers Likely

Lows: 54-60 | Rain: 60%

Monday: Rain, Heavy at Times

Highs: 66-72 | Rain: 80%

Despite plenty of filtered sunshine this morning, this Mother's Day will likely end more gray than glorious as clouds lower and thicken.  With high pressure moving steadily to the east, a southwesterly flow is bringing moist air and increased amounts of cloudiness to areas just west of DC.  A cold front is expected to stall just to our west, which will be a conduit for a low pressure system and some significant rainfall over the next few days.  Today, however, should be mostly dry as the rain will likely begin in the Appalachians and only slowly drift to the east.  Temperatures today will be similar to Saturday's when the high reached 78 at Reagan National. 

Monday and Monday night could be very wet with steady rain and even some thunderstorms dropping up to 2 inches.  The threat of rain continues into Tuesday before a frotnal passage returns drier and warmer days by midweek; highs on Monday will be only in the upper 60s but by Wednesday, we will likely be back near 80.

NOTE: Yesterday marked the 7th consecutive day of  temperatures in the 70s here in DC and the third consecutive day with no recorded precipitation, the driest spell in what has been a generally wet month (still, most days have tallied just a trace of rain).  

Have a wonderful  Mother's Day!
