RAIN-RAIN GO AWAY?????

THE HIGH PRESSURE SYSTEM THAT HAS DOMINATED THE SOUTHEAST UNITED STATES APPEARS TO BE MAKING A SHIFT NORTHWARD.....OVER THE PAST 2 WEEKS, HIGH PRESSURE CENTERED OVER THE SOUTHEAST U.S. HAS FORCED THE DOMINATE WEATHER PATTERNS TO MOVE WEST TO EAST ACROSS THE NORTHERN PLAINS - GIVING US ABOVE SEASONAL TEMPS, HIGH HUMIDITIES, AND RECORD RAINFALLS.

HIGH PRESSURE WILL REESTABLISH ITSELF UP THE EAST COAST AND CENTER OVER EASTERN CANADA. THIS WILL FORCE LOW LEVEL FLOW OVER THE NORTHERN PLAINS AND MIDWEST TO SHIFT TO A MORE EASTERLY PATTERN - HISTORICALLY, THIS IS A DRYER PATTERN FOR IOWA...THAT'S NOT TO SAY WE WON'T SEE ANY RAIN AS LONG AS HIGH PRESSURE IS TO OUR EAST. HOWEVER, WE WILL BE MUCH DRYER THAN THE PAST WEEKS, AND TEMPS AND HUMIDITIES WILL BE MORE SEASONAL......
