Tornadoes in northwest Kansas signal arrival of "second season"

Three tornadoes were reported in northwest Kansas Tuesday night. Fortunately, all of them touched down only briefly.

One was in Sherman County nine miles north of Ruleton, and the other two were in Thomas County: one nine miles south-southeast of Brewster and the other eight miles northeast of Winona.

Second Season is the name for the period each fall when cooler air masses coming down from the north collide with the warm, moist air still holding sway over the Plains. It’s not unlike the set-up in the spring – the heart of tornado season – but meteorologists say second season is not as long or as potent as the prime severe weather window in the spring.

I’ll be hosting another live web chat at 11 a.m. Tuesday to discuss Second Season and other weather topics. Please join me!
