May is our peak month when it comes to severe weather in Kanas. The clash of dry and cooler air from the north meets up with moist air from the south. They do not like each other and thunderstorms will erupt.
We have seen many tornadoes during the first week of May in Kansas’ history. May 3, 1999, Haysville and South Wichita were hit by a tornado that was rated an F-4.
Today back in 2007, Greensburg was hit by an EF-5 tornado that devastated the majority of the town.
Look at a sampling of tornadoes that have occurred in Kansas since 1950 on May 4 alone.
Right now, our severe storm chances are low even with a system coming in overnight. Our dew points are low and the instability is not that high.
Looking ahead over the next week, we do increase our moisture supply with an atmosphere that grows more unstable by the weekend. As conditions stay unsettled next week, severe storm chances look to drop with a reduction in temperatures, dew points and not much instability.
