Significant Changes Possible for Tomorrow Morning

I can not recall a recent event where models have adjusted so severely so close to an event. As a result, what looked looked to be an all rain event for central MD is suddenly looking a bit more promising for some wintry conditions. All models today have come south with the storm which may allow enough colder air to settle in during the predawn hours and change the rain to snow. Right now the areas most likely to see accumulations are along the MD/PA border in Frederick, Carroll, and Baltimore counties where, believe it or not, Winter Storm Watches have been posted for upwards of 5 inches of snow. Presently, that does not include southern Baltimore or Howard counties, but one more tick south and central MD would also be in the game. I’ll be watching the evening model runs closely and will update later this evening.
