Thursday Morning Post 1/17 It's an interesting situation here Today...we'll be right on the fence again with the temps. The GFS is showing a colder solution with a higher QPF than the NAM. This basically looks like an overrunning precip event to me...we should see some snow or a mix of snow and sleet at the onset then it should change over to a mix of rain/sleet and snow. There might be a period of freezing rain Tonight near the PA line that could produce some minor icing. In the DC Metro Area, I'm thinking around 1" - 2" of snow before it changes over to pure rain or a mix of rain and sleet. There could be 2" - 4" of snow in some of the Northern and Western Suburbs before the change over takes place. It will end early Friday morning. The next system is looking interesting as well on Saturday. Many of the models are now forecasting a coastal low out ahead of the massive arctic airmass that will move in on Sunday....more on that later.
