.DISCUSSION...
THE WIND WILL INCREASE FROM THE SOUTH-SOUTHWEST TODAY WITH GUSTS
UP TO 25-30 MPH THIS AFTERNOON.  HIGH PRESSURE WILL BUILD ACROSS THE
OHIO VALLEY ON TUESDAY WHICH WILL CAUSE THE WIND TO BACK TO THE
SOUTH-SOUTHEAST AND TEMPERATURES WILL BE SLIGHTLY COOLER...PARTICULARLY
ACROSS EASTERN MISSOURI AND SOUTHWEST ILLINOIS.  HOWEVER...SOUTHWEST FLOW
WILL RESUME OVER THE AREA WEDNESDAY AND CONTINUE THROUGH THE END OF THE
WEEK.  THIS WILL BRING MOISTURE FROM THE SOUTHERN PLAINS INTO OUR
REGION.  AS A RESULT OF THE WARM TEMPERATURES AND MOISTURE...THERE
IS A CHANCE FOR THUNDERSTORMS FROM WEDNESDAY THROUGH THE END OF THE
WEEK ACROSS MUCH OF THE AREA.
