Discussion

Mild weather will continue today, but big temperature changes are coming to the Mid-Atlantic region on Wednesday. A strong cold front will head towards the Mid-Atlantic region from the Midwest later today and rain will break out early tonight and continue to the pre-dawn hours. The rain can come down heavily at times later tonight and there can be a thunderstorm or two mixed in. Colder air will push into the Mid-Atlantic region on Wednesday following the cold frontal passage. By late in the day on Thursday, clouds will increase around here as moisture streams eastward through the Ohio Valley and into the Mid-Atlantic region associated with low pressure dropping southeastward from the northern Plains. Snow is likely to break out in the DC-to-Philly-to-NYC corridor during Thursday night and continue into early Friday with some accumulations possible by the Friday morning rush hour. The initial low pressure over the Ohio Valley will weaken and transfer its energy to a new low pressure system by early Friday near the Mid-Atlantic coastline.

Looking ahead, it'll remain relatively cold through the weekend and there can actually be more snow or snow showers on Saturday night/early Sunday from a "clipper" type of low pressure system. Beyond that, there are signs for a major warmup by the second half of next week with 70+ degrees likely in much of the I-95 corridor. It'll turn colder again around here, however, by the middle of the month. Elsewhere, perhaps the biggest upcoming weather story will the pounding that California receives over the next few weeks with tons of rain likely in lower elevation locations and several feet of snow in the higher elevations (e.g., Sierra Mountains).
