Severe storms and rain will continue to affect the eastern US through late-week ahead of the chance for some unusual spring snow in the upper Midwest this weekend. This comes as cooler air settles into the Northern Tier while warm air affects the southern half of the nation.

Welcome to the Thursday edition of your Morning Briefing, where weโ€™ll give you a quick rundown on everything you need to know weather-wise, every weekday morning. Letโ€™s dive right in.

Severe Storms and Rain for Eastern US:

  1. A developing and strengthening low pressure currently over the ArkLaTex will head east, making its way toward the East Coast by late-week. Along with heavy rain will also be the risk for severe weather, especially from parts of Texas through the Gulf Coast states.
  2. Today into tonight, the risk for severe weather will shift to the east, threatening the Gulf Coast from southern Louisiana through the Florida Panhandle.ย The best risk this time around will be for damaging winds, but spotty hail and tornado reports are expected.
  3. By Friday, this storm will impact the entire Eastern Seaboard, with rain and thunderstorms expected from Maine through Florida. The rain will be more persistent and widespread across the Northeast and Mid-Atlantic while the showers and storms will be more scattered to perhaps isolated across the Southeast.
  4. There will be the risk for isolated severe storms across the Florida Peninsula and from the Tidewater of Virginia through northeastern South Carolina on Friday.

Snow Possible Across Northern Plains and Upper Midwest:

  1. Low pressure will form by this weekend over the northern Rocky Mountains and move east, threatening the northern Plains and upper Midwest with snow this weekend.
  2. Snow will develop across parts of the Dakotas early Saturday morning while becoming more widespread and expanding to the east. By midday Saturday, however, the snow should end with lingering rain and snow showers.
  3. Snow, some of which may get heavy at times, will affect parts of the upper Midwest Saturday afternoon into the overnight, from southern Minnesota through extreme-northern Illinois (likely north of Chicago).
  4. By Sunday, the chance for snow will move into the southern Great Lakes region and western New York before ending by early-next week.
  5. A narrow band of 6-12 inches of snowfall is forecast from the North Dakota/South Dakota border through southern Wisconsin, with lighter totals north and south of there.

Warm South, Cool North:

  1. A new weather pattern will affect the Lower 48 as we get into this coming weekend, making for a noticeable difference in the weather when comparing the Northern Tier to the Southern Tier.
  2. Widespread high temperatures of 10-25+ degrees below average is forecast across the North beginning Saturday, making for actual highs in the 30s, 40s, and 50s.
  3. Meanwhile in the South, it will be mild with widespread high temperatures generally 5-10 degrees warmer than normal. This will translate to temperatures in the 60s, 70s, and 80s.
