A surface cold front will sweep quickly eastward across these regions during the day today. "At this time, any thunderstorms this weekend should not be strong or severe but this will need to be closely monitored as the late weekend event nears", the NWS added.
Friday we are watching for the possibility for some strong to severe thunderstorms to move through.
A positively tilted upper trough over the Ohio Valley and Great Lakes Friday morning will shift northeastward across parts of the Mid-Atlantic and Northeast through the the next 24 hours. Areas north of the Hal Rogers Parkway and Highway 80 are under a marginal risk (1 out of 5) for severe weather.
Tonight we will see a few scattered rain chances but more showers and storms arrive Friday as a cold front moves in. Please stay weather aware as these storms develop. Temperatures will reach the mid 70s for most, but wherever there is more rain, temperatures will likely be cooler. It's also worth mentioning that we have rain in the forecast off and on again next week, starting back up the second half of Sunday. Dry to start the day with some fog this morning.
