Debris clouds left over from early morning thunderstorms that doused some sections of northern Minnesota have inhibited the daytime heating. However there remains potential for severe thunderstorms for southern Minnesota later this afternoon into the evening. Keep your guard up. It appears that the Twin Cities metro area may be on the northern edge of this outbreak of storms.
The latest from the Storm Prediction Center as of 1230PM CDT:
SUPERCELLS ARE EXPECTED TO DEVELOP IN FAR EASTERN SOUTH DAKOTA AND WESTERN MINNESOTA LATER THIS AFTERNOON. WITH ADDITIONAL HEATING...THESE STORMS ARE LIKELY TO BECOME SEVERE WITH LARGE HAIL AND EVEN A TORNADO OR TWO POSSIBLE WITH THE INITIAL STORMS.
HOWEVER...A FEW HOURS AFTER THESE STORMS DEVELOP...THEY SHOULD EVOLVE INTO A SEVERE THUNDERSTORM LINE. THIS LINE IS EXPECTED TO MOVE SOUTHEASTWARD ACROSS PARTS OF SOUTHERN/CENTRAL MINNESOTA/NORTHERN IOWA AND SOUTHWESTERN WISCONSIN THIS EVENING AND INTO THE OVERNIGHT HOURS.
VERY STRONG INSTABILITY AND SUBSTANTIAL VERTICAL SHEAR WILL BE
FAVORABLE FOR WIDESPREAD DAMAGING WINDS. SOME OF THE WIND GUSTS MAY BE EXTREME...WITH SPEEDS AT OR GREATER THAN 80 MPH POSSIBLE.
