AT 1245 PM...SURFACE LOW PRESSURE WAS LOCATED JUST WEST OF DALLAS FT WORTH. THIS STORM WILL MOVE SLOWLY NORTHEAST ACROSS SOUTHERN MISSOURI ON TUESDAY. THIS LOW IS PUMPING AN INORDINATE AMOUNT OF MOISTURE FROM THE GULF OF MEXICO.

WIDESPREAD RAIN IS EXPECTED FOR THE REST OF THE AFTERNOON AND THIS EVENING.

THE REST OF THE AREA CAN EXPECT AROUND 1 INCH OF RAIN THROUGH NOON ON TUESDAY. THIS WILL LIKELY CAUSE SOME FLOODING OF LOW WATER BRIDGE CROSSINGS AND LOW LYING LOCATIONS.
