…THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF
THE MIDWEST…
…SUMMARY…
Isolated severe thunderstorms will be concentrated across portions
of southern Wisconsin and northern Illinois this evening. Other
strong storms, with isolated severe wind gusts, will be noted from
southeast Kansas – Oklahoma – Texas South Plains.
…01z Update…
Strong short-wave trough is ejecting across the eastern
Dakotas/Nebraska and will approach the upper Great Lakes region
later tonight. Large-scale forcing for ascent is expected to
influence ongoing convection currently located across WI – trailing
into eastern IA. This activity should spread east over the next few
hours with an attendant threat for mainly isolated severe wind
gusts.
Farther southwest, strong boundary-layer heating contributed to
substantial buoyancy which led to thunderstorm development along the
trailing wind shift across KS – northwest OK – southern TX Panhandle
region. This activity is expected to propagate slowly southeast this
evening and locally damaging winds will be the main threat.
