A light round of snow is set to impact parts of the Plains, Midwest, and Mid-Atlantic ahead of a more formidable storm system this weekend, which will bring rain, snow, and severe weather to the East. We’ll also keep tabs on a brief round of warm air for parts of the East Coast ahead of that storm.

Welcome to the Thursday edition of your Morning Briefing, where we’ll give you a quick rundown on everything you need to know weather-wise, every weekday morning.

Light Round of Snow Tracks Across East:

  1. A new disturbance slowly developing over the Plains will be responsible for a new round of snow for portions of the East late-week. Although the snow will be light, some will accumulate and may lead to travel issues.
  2. 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.
  3. 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.
  4. A round of snow will work across the central Appalachian Mountains and into portions of the Mid-Atlantic on Friday. A light to moderate snow is forecast near the Mason-Dixon Line and southwest of New York City Friday afternoon into the evening. The highest risk for this snow will be west of I-95.

Weekend Storm to Bring Snow, Rain, and Severe Weather:

ECMWF forecast precipitation type Saturday
  1. Low pressure will develop Friday night east of the Rocky Mountains, leading to a widespread weather event this weekend across the eastern two-thirds of the nation.
  2. A light to moderate snow is forecast to impact the northern Rocky Mountains, northern Plains, upper Midwest, northern Mid-Atlantic, and New England. Portions of the Northern Tier can expect 8-16+ inches of snowfall.
  3. Widespread rain and thunderstorms will form Saturday across the Plains and will track to the east ahead of the cold front as the weekend progresses. A widespread 0.5-1.5 inches of rainfall is forecast, with totals surpassing 3 inches in parts of the Southeast.
  4. Severe weather, consisting of primarily damaging winds and a few tornadoes, will threaten the Southeast Saturday into Sunday. This event is not expected to be as significant as last weekend’s tornado outbreak, but dangerous weather is forecast nonetheless.

Warm Air Moves up East Coast Ahead of Storm:

  1. As a deepening low pressure forms over the Plains, south and east of the central minimum pressure will be warmer than normal air temperatures thanks to a southerly flow from the Gulf of Mexico.
  2. Widespread temperatures of 5-15 degrees above average is forecast east of the Mississippi on Saturday into Sunday ahead of the cold front.
  3. Temperatures will then decline to up to 10 degrees below average once the front passes through the East Coast by Tuesday.
  4. Actual high temperatures this weekend will generally get into the 50s, 60s, and 70s.
