Storms are on the way! To the left there is a picture of the current stuve diagram from the station in Minneapolis. The indices on the right-hand side indicate the possibility of thunderstorms. The LI index is -3.2 meaning thunderstorms are probable. The KI index is 29 which is in the 50% chance of thunderstorms category. Taking a look at some of the other indices... the EHI (Energy-Helicity Index) is at 2.0 which means Mesocyclone-induced tornadoes are possible (F0-F1 damage).The Sweat index is at 569 which falls in the category of strong risk of severe, few thunderstorms, isolated tornadoes.

Currently, the temperature is 63.9 degrees F with 13 mph SE winds. The dew point is 57.9 degrees F and there is 81% relative humidity. The barometric pressure reading is at 996.5 mb and has been falling for the past 24 hours. The surface map shows a low pressure system right over southern Minnesota. At this spot there is a cold front coming in from the west, and it is mixing with a warm front coming up from the south. With everything that I've just mentioned, thunderstorms are very likely to develop in the next few hours. It will be interesting to keep watching the different maps as the system approaches. After the cold front moves over us, we will have NW winds and colder temperatures. Tomorrow's high is 58 degrees F and winds could occasionally gust over 40 mph.
