Back-to-back storms threatens a round of severe weather, high winds, possible tornadoes and even blizzard conditions into midweek in some sections as warm, moist air from the Gulf of Mexico clashes with colder, dryer air rolling in from the northwest in the nation’s midsection.
If the initial storm this weekend grabs enough moisture, it could spread wind-driven rain and several inches of snow eastward across the North Central states, AccuWeather reports.
“The speed of the arrival of Gulf moisture may be a key player in the extent and nature of severe thunderstorms such as determining whether straight-line wind gusts versus tornadoes are more likely,” says AccuWeather senior meteorologist Alex Sosnowski.
The storm could even dump enough rain over parts of the central Plains in portions of Nebraska, Iowa and Illinois to aggravate recent severe flooding.
For Saturday, the National Weather Service warns of potential thunderstorms across
Texas into the Lower Mississippi River Valley, possibly including severe storms, damaging winds, large hail and tornadoes.
By Sunday, the storm system will likely bring fast-moving showers and thunderstorms to the Great Lakes region and a wintry mix early Monday across Northeast New England.
In Texas, lingering moisture is expected to encounter an upper level trough out of the southern United States and northern Mexico, driving another powerful system eastward across the Mississippi river.
Heavy rain and thunderstorms are possible from the Lower Ohio and Tennessee River Valleys to the Southern Gulf States into Monday, the weather service says.
That will set the stage for the second powerful punch and the threat of heavy snow and powerful winds from Southern California to southern Nevada, Utah, Arizona, New Mexico and Colorado into Wednesday.
AccuWeather Storm Warning Meteorologist Michaela Heeren warns of possible heavy snow and blizzard conditions from southeastern Montana to Colorado from Tuesday into Wednesday.
