A new disturbance slowly developing over the Plains will be responsible for a new round of snow for portions of the East late-week and into this weekend. Although the snow will be light, it will accumulate and may lead to some travel issues. This weekend will be a big travel time period for those on spring break, so this storm system may slow your arrival time to your destination.
The effects of this storm will begin tonight as an area of light snow breaks out across parts of the central Rocky Mountains and Plains. The greatest accumulations will be in those mountains as moisture from the Pacific Ocean gets lifted up, allowing for more moisture to be used and therefore more snow to fall.
Then on Thursday, the snow showers will actually weaken and ultimately dissipate across the central Plains by Thursday night while snow showers move into the lower Midwest, putting cities like Des Moines, Springfield, and Indianapolis at risk for minor snowfall. Snow will not be widespread, but will instead be hit or miss and will be light. Nonetheless, a coating to 2 inches of snowfall will be possible.
Thursday night, the focus of this disturbance will shift to the Ohio River Valley as snow develops and falls around the Ohio River, especially north east of the Louisville area. Thankfully, this snow will not be long-lasting but there will still be some tricky travel for the Friday morning commute.
Speaking of Friday, the Mid-Atlantic will get in on some of the snow action, although by this point in time the disturbance will begin to evolve into a coastal low off the East Coast, but it will pull out to sea and will have little effect on the Northeast once the low pressure develops offshore. Before then, a round of snow will work across the central Appalachian Mountains and into portions of the Mid-Atlantic. A light to moderate snow is forecast as a result near the Mason-Dixon Line and southwest of New York City Friday into Friday evening. The best risk for this snow will be west of I-95, so the major cities like Washington, DC and Philadelphia can expect rain and/or a wintry mix for the most part.
By the weekend, the disturbance will move offshore but there will be another risk for snow across the East as a more-formidable low pressure develops, which we’ll detail more in an upcoming article.
