Low risk for strong/severe thunderstorms

My map is down ATTM so no map will be posted.....There is a low risk for a few strong to severe thunderstorms today...See below...
Today shall be a warm and humid day across the area.Though dewpoints should drop a little in the afternoon,as we get some mixing down from the upper levels,it will still feel rather muggy outside..Temps should have no problem getting into the middle 80s some upper 80s to near 90 not out of the question over the area....Looking at the WV satellite we see a few interesting things...First on is a shortwave over Canada this is moving South/Southeast also a cold front pushing South...These two features will aid in the formation of isolated showers/thunderstorms this afternoon...This is interesting..Models showing some spots of better instability later today...Also do see some vertical shear along with some low level steep lapse rates...This would warrant a chance at some of the thunderstorms could become strong to severe,however does not look like a widespread event ATTM....Though the main threat from any storms that can become severe would be some hail giving the cooler temps aloft and some gusty winds...The area that would have the best chance at seeing strong to severe storms would be over NE to Eastern Central parts of MN and much of our Western/Northern WI.
