.PREV DISCUSSION... /ISSUED 304 AM CDT FRI JUL 25 2014/

DISCUSSION...
QUIET DAY IN STORE TODAY AND REALLY THROUGH THE WEEKEND AS WE WILL
REMAIN UNDER THE INFLUENCE OF AN UPPER LEVEL RIDGE OF HIGH PRESSURE
WHICH IS CENTERED ACROSS THE TX/OK PNHDL. THIS WILL RESULT IN
VIRTUALLY NO CHANCES FOR RAIN THROUGH THE WEEKEND WITH HOT
TEMPERATURES BUT NOT AS HOT AS WE COULD BE IF IT WERE NOT FOR THE
SOIL MOISTURE FROM PREVIOUS RAINFALL EVENTS. WILL KEEP A CLOSE EYE
ON HEAT INDEX TEMPERATURES THROUGH THE WEEKEND BUT WE SHOULD SEE
ENOUGH MIXING DOWN OF DRIER AIR DURING THE AFTERNOONS SUCH THAT
HEAT INDEX TEMPERATURES SHOULD BE BELOW HEAT INDEX CRITERIA OF 105
DEGREES. WARMEST DAY HEAT WISE APPEARS TO BE ON SUNDAY AS WE WILL
COME CLOSE TO CRITERIA DURING THE AFTERNOON.

BY EARLY NEXT WEEK...THE CENTER OF THE RIDGE SHIFTS A LITTLE
FURTHER WEST INTO THE INTER-MOUNTAIN WEST AS A DEEP LONGWAVE TROUGH
CARVES ITS WAY ACROSS THE EASTERN HALF OF THE COUNTRY. THIS WILL
HELP TO DRIVE A RARE COLD FRONT THROUGH THE REGION MONDAY INTO
MONDAY NIGHT WITH ANOTHER SHOT OF MUCH COOLER AIR INTO THE REGION
FOR NEXT WEEK. RAIN CHANCES WILL RAMP UP WITH THE COLD FRONT FOR
MONDAY AND TUESDAY AND THEN WE WILL WATCH FOR POST FRONTAL RAINS
EMBEDDED IN SHORTWAVES COMING AT US FROM THE PLAINS FOR WEDNESDAY
THROUGH FRIDAY OF NEXT WEEK.

PRELIMS TO FOLLOW...13.
