Another Severe Threat On Tap This Week


After a brief reprieve over the Easter holiday weekend, more storms will erupt in the middle in the nation’s heartland by mid-week, potentially leading to the season’s most significant to-date outbreak of severe weather.

An upper-level trough will dig in out west, creating a big bend in upper level winds across the Rocky Mountains, helping to form an area of low pressure on Tuesday. That low will move east, and with a cold front draped below it, it will lead to a clash of warm, unstable air lifted north from the Gulf of Mexico and drier, cooler air behind it. Wind shear, or the “twisting” of winds in direction and at varying speeds, is favorable for the development of supercell thunderstorms that could produce tornadoes, large hail and damaging straight line winds on Wednesday and Thursday in particular.

The first area that will likely get impacted by some of these nasty storms are both Kansas and Oklahoma, perhaps as far east as Arkansas and Missouri on Tuesday afternoon. By Wednesday, the threat moves east and south, stretching from St. Louis, Missouri to Kansas City and southward into Tulsa, Oklahoma and Oklahoma City. Thursday could be the busiest day as the Storm Prediction Center (SPC) has issued a 30 percent confidence rate (higher than Wednesday’s 15 percent) of severe weather in a wide area from Chicago, Illinois to Dallas-Fort Worth, Texas, and several cities in between, including Kansas City, St. Louis, Springfield, Missouri, Little Rock, Arkansas and Memphis, Tennessee.

Many of the ingredients necessary for a widespread severe weather outbreak appear to be in place on Wednesday and Thursday, and there is a good chance that this week’s severe weather could be the most significant outbreak so far in 2015. While dangerous, severe weather outbreaks are a common occurrence this time of year and this is certainly not out of the norm.
