ALSO WITH PRECIPITABLE WATER AMOUNTS OVER AN INCH AND HALF WEST TO AROUND 2.00 INCHES NEAR BISMARCK...WHICH ARE CONSIDERABLY HIGHER THAN NORMAL FOR THIS TIME OF YEAR...WILL GIVE THE POTENTIAL FOR VERY HEAVY DOWNPOURS. BY SATURDAY...THE LATEST 12 UTC MODEL CONSENSUS HAS THE UPPER AIR PATTERN TRANSITIONING TO NORTHWEST FLOW OVER NORTH DAKOTA...PROVIDING COOLER HIGHS IN THE 70S AND 80S SUNDAY AND MONDAY.
