DOUBLE YOUR TROUBLE....
Make no mistake about it, we are entering into an energetic period of weather in the Midwest that will be marked by 2 potent storm systems in the next 5 days. As it stands now, models are in good agreement on the evolution of the first disturbance. They are still struggling on the details of the second.
Due to perceived problems with the U.S. based GFS model, I have relied heavily on the EURO EPS ensembles to base this outlook on.
Storm 1 is due to arrive late Saturday bringing a slug of moisture and precipitation that will linger into Sunday morning. The track will be across eastern Iowa assuring nothing more than a rain event. The surface map at noon Sunday.
The EPS mean shows much of Iowa picking up 1/2 to 1.00" of rain Saturday night and Sunday morning.
