NWS boosts advisory to 3 to 6 inches
Oh my... The overnight storm that was to deliver 1 to 3 inches Tuesday into Wednesday has been boosted to a 3-to-6-incher. The National Weather Service has upped the ante to a Winter Storm Warning, which means we have the potential for more than 4 inches of the White Death.
The Warnings have been posted along a swath (pink on the map) from Northern Virginia across DC to Central Maryland, including Baltimore and the surrounding counties from Montgomery and PG to Arundel, Howard, Frederick, Carroll, Baltimore and Harford.
They have also swept Calvert and St. Mary's into the old Winter Weather Advisory, for 1 to 3 inches instead of rain.
AccuWeather.com's snow map (right) looks like it's been overtaken by events.
So what's going on here? Apparently, better agreement among the forecast models, and therefore greater confidence in the chances for snow, heavy at times through DC and Baltimore, as these weather systems converge on the region tonight.
The WSW opens at 5 p.m. for Baltimore, with snow starting here between 5 and 7 p.m. Will that mean a rush hour snowfall? Maybe. Should folks bug out and head for home early? Drop me a comment when you start to see snow falling where you are.
