CommuteCast: Steamy Not Yet Stormy

By Capital Weather Gang

Heavy t'storms possible tonight, tomorrow

Radar: Latest mid-Atlantic radar loop from the National Weather Service. Click on image to expand, or here to zoom. Refresh page to update. What's UTC?

Storms late this morning caught many of us by surprise and generated a welcome reprieve from the stifling heat. The heat, however, has returned in the past couple of hours and temperatures in most locations have risen to near 90 degrees. While more storms may develop later this evening and overnight, the radar is clear in all directions, so the commute home should be dry.

Tonight: Storm chances will be 50/50, with the most likely timing between 8 p.m. and before 2 a.m., but not restricted to that window. It will remain warm and humid, with lows in the mid 70s.

Keep reading for the rest of the forecast.

Tomorrow: Thunderstorms could develop any time, but are most likely during the afternoon and evening (70% chance). Very heavy rain is possible. If we get enough sun, we could extend our streak of 90 degree days. The other effect of more sun would be to destabilize the atmosphere and increase the risk of severe P.M. storms with damaging winds. On the other hand, clouds and rain in the morning would reduce the risk of intense afternoon storms and hold temperatures in the 80s. Either way, it will be humid and, as a compromise, we'll call for highs of 86-91.

Dolly is now a hurricane.

Uncertain whether severe storms will affect my dance. Seems most likely on the return trip home.

Dolly won't impact us but could enhance the AZ/NM monsoon in a couple days..
