The National Weather Service has expanded a Freezing Rain Advisory that had been in effect for areas southwest and west of the District to now include the entire immediate DC area through 6 pm Monday evening.
Meteorologist Brian Lasorsa tells WMAL News light rain will arrive in the District late Monday morning, and with temperatures at or sloightly below freezing, some light icing could take effect. Temperatures will slowly rise by late afternoon, and should conitnue to slowly rise through the evening, so there should not be a return to freezing pavement conditions after dark.
Lasorsa says the precipitation should not be very heavy, but warns it doesn't take much freezing rain to cause potentially big problems.
Here is the Freezing Rain Advisory from the National Weather Service:
