Low pressure in the Gulf of Mexico states will move northeast toward the Middle Atlantic states and produce widespread rain throughout the region today and early this evening. With mild temperatures, the precipitation will fall in the form of rain. Most locations will receive about 1/2 inch of rainfall by Sunday evening. Some locations may receive a bit more or less. Rainfall is expected to come to an end area-wide by Sunday night. As we move into the new week, colder temperatures will overspread the eastern states. At the same time, a coastal low may bring mixed precipitation to the region by Thursday. At this time, the storm system is projected by computer models to be rather weak with one low moving up to our west and a secondary low developing off the Mid-Atlantic coast. This scenario is not favorable for accumulating snow in the Annapolis area. Even when temperatures are cold enough, this set-up brings very light snow transitioning to sleet and rain. Although the exact details of this system have yet to be determined, right now the prospects for snowfall are minimal through the first week of the new year. Regardless of what occurs next Thursday, chilly air from the northwest will overspread the region through next weekend.
