/ISSUED 211 PM CDT TUE JUN 29 2010/

HIGH PRESSURE AT THE SURFACE AND ALOFT WILL DOMINATE OUR WEATHER
THE REMAINDER OF THIS WEEK. THE RESULT WILL BE NEAR TO SLIGHTLY
BELOW NORMAL TEMPERATURES AND DRY WEATHER.

AN UPPER LEVEL RIDGE OVER THE WESTERN U.S. WILL MIGRATE INTO THE
CENTRAL U.S. BY LATE WEEK. MEANWHILE AN EXPANSIVE SURFACE HIGH
PRESSURE SYSTEM WILL EXTEND FROM EASTERN CANADA INTO THE OZARKS.
THE FLOW AROUND THIS HIGH WILL ADVECT A DRIER AND SLIGHTLY COOLER
AIRMASS INTO THE REGION THE NEXT COUPLE OF DAYS WITH THE COOLER
CONDITIONS MORE NOTICEABLE AT NIGHT WHEN LOWS WILL FALL INTO THE
LOWER 60S PERHAPS INTO THE 50S THE NEXT COUPLE OF NIGHTS.

A RETURN TO TYPICAL SUMMER HEAT AND HUMIDITY WILL OCCUR THIS
WEEKEND. THE CHANCE OF CONVECTION WILL DEVELOP BY LATE IN THE
WEEKEND AND EARLY NEXT WEEK AS DEEPER MOISTURE STREAMS AROUND THE
PERIPHERY OF THE UPPER RIDGE. THE REMNANTS OF TROPICAL STORM ALEX
MAY ENHANCE THE MOISTURE FEED BUT TOO EARLY TO TELL AT THIS POINT.
