Residents are urged to plan for slippery road conditions, starting with the morning rush hour Tuesday-the first day of spring.
"Heavy snow possible", the National Weather Service said in a winter weather message.
This snow could be a heavy, wet snow....that combined with gusty northeast winds may result in downed tree branches, so power outages are possible.
WHERE... Metropolitan Baltimore and Washington areas, as well as the northern and central Shenandoah Valley.
"Plan on hard travel conditions", the weather service said in a statement.
(A Winter Storm Warning from the National Weather Service would be a pretty good trigger to close.) If the big snow totals verify (and/or power outages and coastal flooding recur), we'll probably see delays and closings on Thursday too.More news: Federer Clambers Back to Win
Limited, if any, accumulation is expected Tuesday. An Arlington Department of Environmental Services representative confirmed that the county will not be pretreating for the same reasons, but added that trucks are "ready to treat arterials and any trouble spots should they appear overnight". A reasonable early call would be a widespread 1 to 3 inches with potential for up to 6 in some locations, especially higher elevations.
There will be another storm forming to our south this week, according to the Boston 25 Stormtracker Weather Team.
The more significant storm will reach us around midnight, continue into the morning rush and last through late Wednesday. New snow and sleet accumulation of 3 to 7 inches possible.
I'd really love to say we are nearly done with this pattern.but.we're not.
Assume any "wet" pavement to be slick.
So, in general, climatologicially speaking, right now the atmosphere is warming and that means it takes a lot colder air to cool things down enough for a purely snow event.
