WINTER PRECIPITATION HAS BEEN AROUND 2 TO 4 INCHES BELOW NORMAL
FOR MOST OF THE AREA...LEADING TO A BELOW NORMAL CHANCE OF
FLOODING.  THERE IS SOME POTENTIAL FOR LOW FLOW ISSUES THIS
SUMMER IF BELOW NORMAL RAINFALL PATTERNS CONTINUE THROUGH THE
SPRING AND SUMMER.

MOST OF THE AREA IS CONSIDERED ABNORMALLY DRY /D0/...WITH A SMALL
REGION OF INITIAL DROUGHT /D1/ IN WESTERN MINNESOTA. THE OUTLOOK
CALLS FOR THIS PATTERN TO PERSIST INTO THE SPRING. FOR MORE
