Severe weather possible Friday

A cold front is projected to move across Minnesota during the day on Friday and exit the area by the overnight hours on Saturday.

Out and ahead of the cold front, another hot and humid day is on tap for Friday as temperatures will remain in the mid-90s for a second straight day with dew points well into the 70s.

The front will be the focus for thunderstorm development during the late afternoon and early evening hours.  A very unstable air mass is in place with a cap expected to weaken as the day moves along that will be the focal point for severe thunderstorms.  The greatest potential for severe weather appears to be along the Minnesota Highway 23 corridor from Marshall through St. Cloud to Hinckley.  It appears the time frame for thunderstorms rumbling through the state will be between 4 and 8 PM.  I’m expecting more of a line of embedded thunderstorms will large hail and strong winds as the main threats, although a tornado is possible early in the storm evolution.

With this being a travel weekend with the 4th of July weekend, you’ll want to keep an eye to the sky and radar before you head out on the roads.

Have a great holiday weekend!
