Several rounds of severe thunderstorms will rumble across Tornado Alley from Tuesday afternoon to early Wednesday morning. The NOAA/NWS Storm Prediction Center tagged a belt from Iowa to Texas with an enhanced risk of severe weather in its Tuesday outlook, surrounded by a larger slight-risk area. A small part of western Oklahoma and the eastern TX panhandle was upgraded to a moderate risk in SPCs 11:30 am update.
The entire gamut of severe weather could materialize on Tuesday, including one or more strong tornadoes, giant hail, wind gusts topping 75 mph, and extremely heavy rain. However, these threats will not be distributed evenly across the SPC risk areas.
Central Plains cluster. The high-resolution HRRR model shows thunderstorms firing as early as mid-afternoon in southwest Kansas, on the nose of the surging moisture and just ahead of a dryline (see our dryline explainer from last Friday). These storms will likely expand into a large mesoscale convective system, bringing very heavy rain, large hail, and howling winds to northeast Kansas, eastern Nebraska, and western Iowa. As the complex matures and expands, the tornado threat should decrease, but localized flash flooding could developespecially in parts of central and northeast Kansas, where the storms could dump 2 to 4 of rain in short order. Omaha, Des Moines, and Kansas City could get hammered by this storm complex on Tuesday night.
