Severe storm chances will be ramping up across the central US Saturday. We’ve been monitoring a trough of low pressure bringing snow to the northwest and high plains. As that wave of energy crashes into a surface low pressure system, strong storms will pop up this afternoon.
Copious amounts of moisture on the backs of southerly winds will supply the storms throughout the day. A developing center of low pressure sliding northeast along a once stalled out front will provide some rotation to the mix. The track of the low is where we find an enhanced risk of severe storms and a five percent chance of tornadic activity. Big cities potentially impacted include Chicago, Milwaukee, Kansas City, Peoria, Kirksville, the Quad Cities, and Cedar Rapids.
As a cold front comes through behind the low, these storm cells will likely combine into a large line. The threat will then shift to damaging winds and flooding rains. Flood and Flash Flood watches have been issued for communities to the north along the warm front. After a soggy morning, rain will not give up for the rest of the day.
However, it’s that morning rain that could limit the afternoon threat of strong storms. Where some clearing has already taken place, spots in Missouri and Kansas have already started to see instability go up. But were rain has stayed steady, the atmosphere hasn’t been given a chance to rebound. Stick with WeatherNation through the day for more updates on your hourly forecast.
