A strong cold front is expected to head southward through Virginia on Friday, bringing a good opportunity for rain during the day, and also ushering in much cooler weather Friday night. Here is a look at the cold front Friday morning:
You can see where it's draped through southern Pennsylvania, Ohio, and Indiana. This front will track south of the Commonwealth by late Friday, allowing for clearing skies and dry weather for Saturday morning. While I'm sure most of us will be glad for dry weather Saturday, the flip side to the cold front is, of course, the cooler air coming with it. This means Saturday morning will be cold, likely in the mid-30's at the start of the 10K. Temperatures will not reach the low-50's until after 11am Saturday, so I would advise dressing in layers if you're headed out to either run in or cheer on the runners (don't miss the CBS 6 10K Team!) at the race.
