Severe Threat Across Plains for Thursday
While all eyes across the United States are on powerful Hurricane Matthew in the western Atlantic Ocean, another potentially significant severe weather threat is expected to move into the central Plains states on Thursday afternoon.
An area of low pressure moving out of the Rocky Mountains and a cold front draped ahead of it will lead to a clash of air masses and strong storms on Thursday afternoon from Texas to Iowa.
The main threats with Thursday’s storms will be very large hail and strong gusty winds, but tornadoes will also be a possibility, particularly in the ‘enhanced’ risk zone (in orange, map above). The tornado threat is expected to be mostly isolated on Thursday.
In Iowa, barely a week removed from the state’s most significant floods in nearly a decade, more unnecessary rainfall could lead to an enhanced flood risk across the region.
Tuesday featured a string of strong storms across Oklahoma, Kansas and Nebraska, with hail sizes as large at two inches with those storms.
While the prime severe weather season is typically associated with the spring months of April, May and June, a secondary season is often seen during the fall months as warmer and more humid air masses collide with cooler, denser air. Severe storms in September, October and November are far from uncommon – many may remember the November 2013 tornado outbreak that primarily impacted Illinois as a stark reminder of the potential for powerful autumn storms.
