It is currently 17° F in Glenmont, and a super-frosty 14° in Burtonsville.
We are now under a Winter Storm Warning across the DC Metro area, from 7:00 tonight, through Thursday evening. Expect the real snow to start after 8:00 PM tonight, with accumulation of 4-8 inches by Thursday afternoon. The temperature could drop into the upper teens tonight. Temperatures in the low 30s on Thursday could create a mix of snow and freezing rain. Because atmospheric conditions suggest a heavy, wet snow, cleanup will be more difficult, and power outages are likely. Winds will pick up Thursday, with gusts in the 30 MPH range, adding to the likelihood of outages.
Some stores appeared to be running low on the most popular types of milk last evening, but most other items were in stock.
Take a flashlight, food and water in your vehicle if you must travel during Wednesday night and Thursday morning.
