FOLKS
Many of you have heard of the minor to moderate flooding that occurred in TN and KY. Lower IND Lower OH and Lower ILL saw hefty rains as well.

Things will be drying out over the next few days but I wainted to tell you of 3 important weather events coming next 10 days-- a Sproing snowstorm and a very WET overall pattern for the Ohio and Tennessee valleys from March 25 to April with 2 MAJOR rain event.

After this current cold shot sweeps thru the nation over the next 48 hours a new Cold High pressure system will drop in from Canada early next week... bringing below normal temperatures to the Upper Plains and Great Lakes as well as set the stage for a spring snowstorm over SD IW MN northern NEB and possibly Northern ILL (chicago) and Northern Indiana .

A large and significant trough is going to approach the West coast this weekend and bring rain to much of CA and the Western US and snow above 3500 feet. As this system crosses the Rockies two areas of Low pressure will develop. The first one will be over the Central Plains
March 25 and it is this Low that will use the cold air supplied by the cold High over the Upper Plains to produce a SIGNIFICANT spring snowstorm over the areas I mentioned above (SD IW MN northern NEB and possibly Northern ILL including chicago). This Low will also provide rains to MO central and lower ILL IND and much of OH and KY. Snow amounts will run something along the lines of 3-6 inches or 4-8 inches and the rain will be 0.25 to 1.00" and coverage 75%.

Then the first Low pressure area will die as it runs into a strong ridge of High pressure off the East coast in the upper atmosphere. Strong southerly winds will bring up very moist air into the Eastern US (east of the Mississippi river). A SECOND Low pressure area will form over the Delta region and bring HEAVY rains to the Tennessee and
Ohio valleys -- including the ECB -- March 26-28. Rain amounts of 2 to 5 inches are easily possible (!!!) and may cause widespread flooding that will see a lot of Media coverage.

Then there may be a third system for the same areas behind that one for the period of March 31- April 2!
