With a National Weather Service winter storm watch in place for Thursday morning for Northern Virginia, school and utility officials and crews with the Virginia Department of Transportation have their eyes glued to the weather forecasts.

As the forecast changes, VDOT will have 650 trucks ready to roll out Thursday morning to pre-treat interstates in Fairfax, Arlington, Loudoun and Prince William counties, agency spokeswoman Jenny McCord said. If the forecast changes and more snow hits the region, McCord said VDOT is prepared to bring in extra workers.
