Montgomery County and those west to Allegany County are also in a Winter Storm Watch now.
And the NWS snow forecast map (left) has been beefed up some, too, now. (Is this starting to feel like the accumulation estimate escalation we saw so much last winter?) For a better look at the map, click here.
The Watch calls for 5 inches of snow or more, amid a mix of snow, sleet, freezing rain and rain. The precipitation would begin in the late afternoon Wednesday in Baltimore's suburbs, changing to snow as temperatures drop into the upper 20s Wednesday night.
A Winter Storm Watch means there is a potential for significant snow, sleet or ice accumulations that may impact travel. Forecasters urge those in the Watch area to monitor the latest forecasts.
