Many people living in the US such as those in the Ohio Valley and Midwest are welcoming news of the warmup that’s approaching. Unfortunately however, with the unseasonable warmer weather comes a real threat of severe weather. There is a good chance that severe thunderstorms will erupt in the Ohio Valley region and the Southeast starting Thursday. Temperatures on Thursday will reach into the low 70s in places such as Memphis and Nashville and in the 60s over an area stretching from St. Louis to Cincinnati which means any precipitation that falls will be in the form of rain.
An upper disturbance that’s rolling in with the jet stream is what will push the temperatures up as warm air is being drawn northward out of the Gulf. This makes conditions just right for severe weather which includes heavy thunderstorms, high gusting winds and hail. Along with this very unstable weather pattern also comes the possibility that tornadoes can form. However, a widespread outbreak of tornado activity is unlikely. Instead, a few isolated, smaller twisters may form which could nonetheless cause damage and threaten lives.
Forecasters say that the inclement weather heading into the Ohio Valley could even make its way into the extreme southern portions of Michigan by Thursday night. The severe weather could batter that part of the Great Lakes State with rainfall, winds in excess of 50 miles per hour and hail stones the size of ping-pong balls.
The National Weather Service said early Wednesday that Tulsa, Kansas City and Springfield are at risk for the worst of the severe weather Wednesday night. Then by Thursday morning as the system moves east, Nashville, Cleveland and Cincinnati may see strong winds, heavy rain and hail. The NWS says that there a 50 percent chance of tornadoes forming over central Missouri on Thursday and a 40 percent chance of twisters for western and central Kentucky.
While the warmer weather heading for the Midwest will be welcomed, the warmup could cause some problems as far as flooding is concerned. Many areas in the Midwest have one to two feet of snow on the ground. There is at least 6 inches of water locked up in the snowpack in Michigan where there’s more than 2 feet of snow on the ground in most places. When the snow does begin to melt, water will run-off into ice-clogged streams and rivers and into low-lying areas which very well could cause some significant flooding issues. On Thursday when the next weather pattern moves into the Midwest it will dump some snow, mixed precipitation and rain to cause even more concern for flooding.
