GREAT VIEW OF CONVECTION WHICH DROPPED LARGE HAIL NEAR ST. LOUIS EARLIER TODAY! (credit: @Wx_Geek)

DISCUSSION: As a weak pulse of energy moved through the greater North-Central Mississippi River Valley region earlier today, strong to severe thunderstorms erupted just west of the greater downtown area.  As these severe storms moved through the greater St. Louis metro area, very large hail (i.e., roughly tennis ball to baseball-sized hail) for a brief time between 1:00 PM and 2:00 PM CST.  Note how during the brief high-resolution satellite loop below you can see the small area of bubbling white clouds quickly blossom just prior to the heaviest rainfall and the largest hail occurring.  For more on other neat high-impact weather content from across the United States, be sure to click here!
