Read the full account →A very dynamic weather situation unfolded during the 5th into the 6th. Although the atmosphere was summer like in the lower elevations, the upper levels were more typical of April.
Read the full account →The frontal system that moved into the state the previous night was located over southeast Iowa during the afternoon of the 12th. The atmosphere became unstable during peak heating with MUCAPE around 2000 J/kg. There was 50 to 70 kts of effective shear across the area.
