Severe Weather Likely Today from the Upper Midwest to the Central Plains

15 May 2017, 10:22 am

A storm system moving through the Upper Midwest into the Central Plains will likely produce a couple of rounds of severe weather today. The Storm Prediction Center has posted an enhanced risk for severe storms in parts of Minnesota, Iowa, Wisconsin and Illinois.

There is a risk for strong winds in Southern Minnesota and Northern Iowa this afternoon, with the potential for large hail and isolated tornadoes increasing later this evening in the region. Hail and strong gusty winds are possible in the Texas and Oklahoma Panhandles late this afternoon.

A rich feed of humidity will be coming in from the Gulf of Mexico with southerly winds ahead of the storm system. Warm air will be pushed northward as well, building instability. In the upper levels of the atmosphere, Jet Stream energy will be digging in from the West, aiding the support aloft for severe weather development.

The first wave of strong storms will push through Southern Minnesota and Northern Iowa this afternoon, bringing the chance for strong wind gusts. As the storms move into Wisconsin, they will gradually weaken.

An outflow boundary will likely form behind the storms, colliding with a stalled front. This will help to produce another round of severe storms this evening, close to I-90. Supercells are possible, with the potential for large hail and tornadoes.

Into the overnight, clusters of showers and storms are likely. Heavy rain, large hail, and isolated strong wind gusts may occur over the region.

Further south, isolated severe cells will develop in the late afternoon from Western Kansas to North Texas. Hail and wind are the biggest concern with these storms as they develop. The storms will diminish late tonight, after sunset.
