CommuteCast: Calm Before the (Next) Storm

More rain arrives overnight and for morning rush

A somewhat cool May afternoon has unfolded across the area today. High temperatures in the mid and upper 60s are about 5 to 10 degrees short of average for this time of year, and gusty winds from the northwest have added a little extra chill to the air. Winds will slowly diminish this evening as another weather system approaches the area.

Tonight: A weak wave of low pressure will begin to affect the area overnight, first with increasing clouds, then with precipitation beginning between midnight and sunrise. Low temperatures will fall into the upper 40s in the suburbs and the low 50s in the District.

Tomorrow: Tuesday begins rainy, and some of the heaviest precipitation is likely to coincide with the morning commute. The quick-moving low pressure system will then begin to exit around midday -- though a few showers are possible into the afternoon. Most totals will be between .50" and .75" across the area, with a few higher numbers possible. Some breaks in the clouds are possible prior to sunset, but not enough to get high temperatures much above 60 degrees across the area.
