Area forecast discussion, Jun 24, 7:55 PM CDT, 36 minutes before
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORMAN OK
755 PM CDT TUE JUN 24 2014

.UPDATE...
INCREASED RAIN CHANCES THIS EVENING AND DECREASED OVERNIGHT
LOWS OVER THE NORTHERN HALF OF OKLAHOMA.

&&

.DISCUSSION...
THUNDERSTORMS OVER NORTHERN OKLAHOMA WILL CONTINUE TO MOVE
SOUTH AND LIKELY WEAKEN THIS EVENING.

A WEAKENING TREND MAY ALREADY BE OCCURRING WITH THE
LINES/CLUSTERS OF STORMS OVER NORTHERN OKLAHOMA. THE LOSS
OF DAYTIME HEATING AND LACK OF STRONG SHEAR WILL LIKELY
ALLOW FOR THE STORMS TO CONTINUE TO SLOWLY WEAKEN THROUGHOUT
THE EVENING.

REGARDLESS...ONE OR TWO MARGINALLY SEVERE WIND REPORTS...NEAR
60 MPH...AND HAIL REPORTS UP TO QUARTERS...COULD OCCUR THIS
EVENING NORTH OF I-40.

STORMS COULD MOVE INTO THE OKLAHOMA CITY METRO AREA 10 PM
TO MIDNIGHT...BUT SHOULD BE WEAKER. NOT CONFIDENT STORMS WILL
GET TO I-40 AND POINTS SOUTH LATER TONIGHT.

LOWERED OVERNIGHT LOWS AS RAIN COOLED AIR FROM THESE STORMS
OVER NORTHERN OKLAHOMA WILL SPREAD SOUTH.

AVIATION...
MESSY FORECAST THIS EVENING AS THUNDERSTORMS CONTINUE TO BUILD
SLOWLY S/SE OUT OF KS INTO NRN OK THIS EVENING. TIMING REMAINS A
CONSIDERABLE CHALLENGE... SIDED WITH TEMPO GROUPS AND MVFR
CIGS/VIS AT KGAG- KWWR- KPNC TO HANDLE STORMS AS THEY MOVE INTO

MVFR LATE MID-LATE IN THE PERIOD.

JTK

PREV DISCUSSION... /ISSUED 311 PM CDT TUE JUN 24 2014/

DISCUSSION...
THUNDERSTORM COMPLEX WILL CONTINUE TO MOVE ACROSS SOUTHERN PARTS
OF THE FA THE REST OF THIS AFTN AND EVENING. ADDITIONAL STORMS
THAT HAVE DEVELOPED OVER KANSAS THIS AFTERNOON WILL LIKELY AFFECT
PARTS OF AT LEAST NORTHERN OKLAHOMA LATER THIS AFTERNOON AND THIS
EVENING. SOME STRONG TO SEVERE STORMS WILL BE POSSIBLE. ADDITIONAL
STORMS THAT DEVELOP IN THE HIGH PLAINS OF CO AND NM COULD CONGEAL
INTO ANOTHER MCS THAT MOVES ACROSS THE FA OVERNIGHT INTO WEDNESDAY
MORNING. HOWEVER... THE EFFECTS OF THE CURRENT CONVECTION COULD
HAVE AN IMPACT ON OVERNIGHT CONVECTION.

DISTURBANCES WILL CONTINUE TO MOVE THROUGH THE FLOW OVER THE NEXT
COUPLE OF DAYS... WHICH MEANS SHOWER AND THUNDERSTORMS WILL REMAIN
POSSIBLE THROUGH AT LEAST THURSDAY. LOWER RAIN CHANCES TO NO RAIN
WILL BE POSSIBLE OVER THE WEEKEND. MODELS SHOW THAT A RIDGE MAY
BUILD INTO AT LEAST PARTS OF THE REGION OVER THE WEEKEND WHICH
WILL LIMIT OR END RAIN CHANCES OVER AT LEAST PARTS OF THE AREA.
