SCATTERED SHOWERS/STORMS WITH FRONTAL ZONE FROM UPPER MS
VALLEY/WESTERN GREAT LAKES THROUGH OH VALLEY INTO MID MS VALLEY
AND CENTRAL PLAINS WITH SCATTERED SHOWERS/STORMS ACROSS THE FL
PENINSULA AND A BRUSH OF PRECIP ALONG THE SOUTHEAST COAST. THEN
TUES THROUGH THURS, VERY HEAVY RAINS CONTINUE FROM THE MAIN
CORRIDOR OF LA/SOUTHEAST TX UP THE MS RIVER TO THE SOUTHERN OH
RIVER VALLEY AND MORE SCATTERED SHOWERS STORMS WITH THE RETURNING
NORTH SYNOPTIC SCALE FRONT NORTH AND EAST OF HARVEY.
