Another active day of severe weather is ahead for parts of the central US, especially this morning. Meanwhile, there will be a significant risk for flash flooding for the foreseeable future across the South due to the persistent rounds of rain and storms. One of these large-scale storms will then reach the East Coast this weekend, making for some ugly weather.

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. Let’s begin.

Severe Storms Threaten Parts of Central US Today:

  1. Today’s severe weather threat will not move much compared to yesterday’s, spanning from the Ohio River Valley back through eastern and southern Texas. The highest risk for more intense storms, however, will be across the ArkLaTex and Mid-Mississippi River Valley. 
  2. All modes for severe weather are possible, with wind and hail as the greatest threats. Isolated tornadoes are also expected.
  3. Unlike a classic severe weather threat when the most active weather takes place late in the day, we expect the worst storms will actually be this morning due to the strong line of thunderstorms from last night that has maintained its strength.
  4. By Friday, although the risk for intense storms should diminish for the most part, some marginal risk cannot be ruled out across the Central Appalachian Mountains.

Southern Flood Threat:

  1. Spring has been quite wet across the Southern US this year, especially these past few weeks as large storm systems form over the Southern Plains. These systems are known for bringing copious amounts of rain through the region thanks, in part, to the nearby moisture flowing in from the Gulf of Mexico.
  2. Parts of the South will get somewhat of a break late-week before a new storm brings widespread heavy rains to the region this weekend. Thankfully, the pattern should then quiet down early-next week, allowing for at least a 3-5 day dry period for most areas.
  3. Through this weekend, a widespread 2-4 inches of rainfall is forecast from eastern Texas through the Mid-Mississippi River Valley, with isolated amounts of up to 1 foot.
  4. These heavy rainfall amounts will lead to some flooding, including flooding from the rising rivers.

East Coast Rain Makes for Ugly Weekend:

  1. The same storm system that will develop over the South this weekend will also bring rain and even some thunderstorms to the East Coast, even on Mother’s Day this Sunday.
  2. Saturday, showers will spread across the Mid-Atlantic, Appalachian Mountains, and much of the Southeast while cloudy, but mostly dry, conditions mainly affect the rest of the Northeast.
  3. It’s not until Sunday when rain will take over the East Coast, with the heaviest rainfall expected late in the day and overnight, dropping 0.5-2″ for most areas.
  4. The precipitation won’t move out of the region fully until Monday or Tuesday, while some of the mountainous areas of New York and northern New England may even experience some snow. If snow does occur, only few inches would accumulate.
