Snow Still Set But Stickage In Question

February 9- It is snow as expected this morning and the storm or deformation zone has set up. The issue has been the temperatures and a matter of one or two degrees.  When schools had to make their call- it was snowing but many roads were wet. That’s not easy to deal with since conditions can go either way… As of 5 AM, Baltimore’s BWI 34F, but temps are at freezing north and west of the Beltway. We can thank an east wind off of the warmer Chesapeake Bay, which will keep nearby places warming and limit stickage.  But inland is where it will be slick. The grass will get covered in most places, which is where we will measure… but the pavement is what really matters.

UPDATE: See notes from 6:30 AM as the snow continues to expand

Schools don’t have an easy call as this will be developing all morning and roads have been wet. But increased snow can overtake the warmer ground. Elevated surfaces like bridges will ice up in those colder inland places, so please be careful driving overpasses. I would expect north and west of Baltimore has the most likely concern. The City and Anne Arundel County roads likely to remain mostly wet. But my suggestion has been to wait for a few hours to see how this develops. The most tricky time will be between 6 AM and 9 AM. Snow will continue after that, but daylight and warmer temps should help.

Winter Weather Advisory: Maryland

Due to the slight temperature adjustment… The National Weather Service has cancelled the Winter Storm Warning in Maryland and a Winter Weather Advisory is in place. It is just a slight lowering of snow expectations, still on the lower end of my map ranges.  The Warning is still in place for southern PA, and I would consider northern Maryland (Carroll County, Baltimore, and Harford Counties) within 10 to 15 miles of the PA line in potential for icy roads as well.

If you live near I-95 or the Bay, Baltimore City/Anne Arundel County, expect snow to stick on the grass, but the roads might remain wet. Just a few hours this morning when heavier snow could briefly overtake the roads.

Snow Timeline: Watch the Freezing Line

It will snow in places that remain above freezing. That is why roads should remain wet. But the freezing line and heavier snow bands will be worth close consideration on the north and west side.
