Environment

The near storm environment was driven primarily by large instability. This was due to steep mid level lapse rates overtop a warm and humid airmass south of a warm front. The storms developed across that Dakotas and western Minnesota, and moved into east/southeast during the late evening and overnight.


July 29, 00Z 500mb heights and wind showing west-to-east flow across the Upper Midwest.	July 29, 00Z surface map showing a warm front across southern Minnesota.	July 29, 00Z forecast sounding from the NWS Twin Cities forecast office in Chanhassen MN showing steep mid level lapse rates, and increasing winds aloft.


July 29, 00Z 700mb to 500mb Lapse rates showing values 8.5 to 9 C/km! This allowed a strong cold pool to develop, which factored into the longevity of the system.
