.PREV DISCUSSION... /ISSUED 401 AM CDT MON JUL 27 2015/

DISCUSSION...
SCATTERED SHOWERS AND STORMS WILL BE POSSIBLE OVER NORTHWEST
PORTIONS OF OKLAHOMA THROUGH MID-MORNING AS OUTFLOW BOUNDARY FROM
KANSAS MCS PROGRESSES SOUTHWARD INTO BODY OF OKLAHOMA. GREATER WAA
ABOVE THIS BOUNDARY EXPECTED NORTH OF THE KANSAS BORDER WITH
WEAKER LLJ AND BAROCLINICITY AS YOUR WORK YOUR WAY SOUTH INTO
CENTRAL PORTIONS OF OKLAHOMA. AS LLJ WEAKENS ALL RAIN ACTIVITY
SHOULD QUICKLY DISSIPATE WITH ANOTHER HOT AFTERNOON EXPECTED.
FORECAST TEMP/TD TRENDS WILL YIELD HEAT INDICES AOA 100 BUT BELOW
HEAT ADVISORY CRITERIA. CAVEAT BEING THAT OUTFLOW BOUNDARY MIXES
BACK NORTH AS PROGD. IF IT DOESN`T...WE COULD SEE SOME MOISTURE
POOLING NEAR BOUNDARY AND ELEVATE HEAT INDICES INTO ADVISORY
LEVELS ACROSS FAR NORTHERN OKLAHOMA THIS AFTERNOON. THIS WILL BE
WATCHED CLOSELY BY DAY SHIFT.

FORECAST OF INCREASING POPS ACROSS NORTHERN OKLAHOMA BEGINNING
TUESDAY AND PROGRESSING SOUTHWARD INTO LARGER PORTION OF CWA
THROUGH THE WEEK STILL LOOKS GOOD AS STRONG UPPER S/WV PROGRESSES
EASTWARD OVER NORTHERN AND CENTRAL PLAINS EARLY THIS WEEK. THIS
WAVE WILL ALLOW SURFACE BOUNDARY TO SHIFT SOUTHWARD OVER CWA.
TEMPERATURES WILL ALSO TREND A LITTLE COOLER WITH INTRUSION OF
WEAK COLD FRONT. SOME SUB-90 DEGREE HIGHS APPEAR POSSIBLE ACROSS
NORTHERN OKLAHOMA MID-LATE WEEK IF CLOUDS CAN LINGER LONG ENOUGH
AFTER OVERNIGHT/MORNING CONVECTION.
