The heat, but tomorrow it will be for storms. I think most of us will have a dry commute to work. By 8 30 its 83 downtown, still in the upper 70s. Back to the west in the mountains storms will be forming already and then by 11 30 already some storms in western Loudoun County and a pretty good area of storm. You see the red between winchester and luray . Those are pretty heavy storms developing moving essentially east. Right around lunchtime weve got big storms out 66. Dont get too hung up on the exact location of this little cluster of storms. It could just as easily be into leesburg and gaithersburg. Thats by 1 30. Then by 2 30, 3 00 most of the heavy activity is across i95 into Southern Maryland and across st. Marys county and charles county. Well come back and take you through the evening commute and tell you how much more comfortable it will be after the front rolls through on wednesday. Thanks, top. The long ride home is finally over tonight for hundreds of rail commuters. A marc
