From Blade Runners Monday early afternoon: "We did not get the higher temperatures and rain as forecast. This has created some unwanted residue on the roadway. The treatment from last night will help to melt this off over the next 3 hours. There are likely to be small amounts of re-freezing tonight. We would normally be performing touch-ups to these areas today but we must prepare for the storm tomorrow. Roadway plowing: Will begin at 2 inches tomorrow. Ice Control: None planned until after plowing."
NOAA NWS forecast for Fairfax County as of 12:30 p.m. today: Monday night ... slight chance of rain, then snow, sleet likely, slight chance of rain and freezing rain after midnight. Tuesday ... morning snow and sleet, then chance of afternoon snow, accumulation 3-5 inches.
