Morning GOES 1km visible satellite shows upper air low tracking through southwest Minnesota. The low is moving northeast towards the Twin Cities.
An upper level wave is increasing shower and thunderstorm coverage in southern Minnesota today. The chances for rain are increasing for the metro as the low is taking a more northerly track this morning.
Scattered showers and thunderstorms are developing ahead of the low and moving east to northeast. The chances for rain are increasing for the Twin Cities and the PGA Championship in Chaska. I hope fans brought some umbrellas today out to Hazeltine.
The heaviest and most concentrated area of storms may pass just south of the area today, but the chances of rain at Hazletine will increase after 11 am. Keep an eye out for lighting at Hazeltine today.
