A cold front will be pushing south and eastward through the Eastern US heading into the weekend. Expect widespread showers and thunderstorms during much of the weekend. Behind the cold front will be cooler air and a brief reprieve from the active weather as high pressure moves overhead for a very short period.
Most of the activity will occur on Friday. On Friday morning a line of rain and embedded thunderstorms with patches of heavier rain will span from southern New England through the Ohio Valley and into portions of the Southern Plains. There may even be a line of thunderstorms ahead of this main line, spanning through the Tennessee Valley and into the ArkLaTex region. Colder air is expected to override the moisture across western and Upstate New York and into northern New England. This will translate to a light to moderate snow during the morning hours before ending during the early-afternoon. There is also the chance for a brief period of snow on the backside of the precipitation in portions of the Ohio Valley, but we aren’t really concerned about much wintry weather in this region.
As we get into the afternoon, the cold front will continue to push the moisture further south and east. Rain is expected to shut off north of the Ohio River and into New England while the rain continues or begins across the Tennessee Valley and into the ArkLaTex. Spotty rain showers are also possible in the Mid-Atlantic region and the Southern Plains.
During the overnight hours of Friday, our next storm system, which will make for our incoming winter storm to the Northeast, will begin to bring rain to parts of the Southern Plains and into the Mid-Missisppi Valley. Meanwhile with our cold front ahead of this storm, the rain activity will dwindle down during the evening as the cold front stalls out and loses its forcing. However, a few lingering, widely scattered showers are still possible in the Southeast.
Thankfully, most of this rain will be light, so flooding is not expected. Less than an inch of rain is forecast to fall in most areas.
