Large Low Pressure System and Tracking the Rain for the First Day of Autumn
The day before Autumn starts, will see the arrival of cooler temperatures. The main focus is going to be the low pressure system, and the associated cold front bringing rain into much of the Southeast and East Coast along with rain in the Upper Great Lakes Region. Following the low will be an extensive high pressure system pulling cooler air in behind it into Minnesota and Wisconsin.
The Atlantic Hurricane season is still in full swing, and an area of low pressure is being monitored for the possible development into a Tropical Depression around this time frame.
