Strong Fall Storm Sweeps Across the Midwest

23 Oct 2009, 1:26 pm

Heavy rain continues to inundate the Midwest as a strong fall storm sweeps across the nation.  Daily maximum rainfall amounts have been broken across the center of the country and rivers and streams along the Mississippi river have swollen past flood stage.  Strong storms like this one are not uncommon this time of year.  During early spring and fall, large temperature differences usually exist from north to south across the country.  Locations in the Northern Plains and Midwest have been in the 30’s and 40’s whereas areas ahead of the storm in the Ohio River Valley have been in the 60’s and 70’s.  Mid-latitude cyclones, as they are called, get their strength from these large temperature gradients along with ample atmospheric moisture…both of which are often present this time of year.

This storm is quickly moving into the Northeast tonight.  Heavy rain will fall in some areas of the Northeast…I know, just in time for the weekend.  Not the best weather for leaf peeping.  Also, with the leaves starting to fall off the trees, some drainage areas could get clogged, potentially causing localized street flooding.  If you encounter a flooded roadway…do yourself a favor…follow the old saying, “Turn Around, Don’t Drown.”  Don’t take your chances like some of us did down south yesterday.
