Some light snow is falling along the MD/PA border this morning, but for central MD the morning commute should be weather-free. Mixed precipitation will develop across the area later this morning and eventually change to snow from west to east during the afternoon. Temperatures will slowly fall and by sunset, most areas will be below freezing which will make for very dangerous driving conditions. The snow will end from west to east from about 8-10PM with total snow accumulations of a coating to the south and east towards the bay, to two inches in the interior areas. North of I 70, 2-4″ is possible.
Some school systems are already announcing two hour early dismissals, and I expect others to follow. If you don’t have to drive this evening, just stay in.
Icy conditions will likely persist into Wednesday morning, and short range models are all picking up a significant snow squall line tomorrow during the late morning or early afternoon. We can discuss that in more detail later today.
Expect very cold temperatures for the remainder of the week, and another small snow disturbance possible Friday evening.
