Hazardous weather outlook, National Weather Service, Norman

DISCUSSION…
ISOLATED THUNDERSTORMS MAY FORM THIS AFTERNOON AND EVENING IN A
CONTINUED WARM… HUMID… AND WEAKLY-CAPPED AIR MASS. A RIDGE OF
HIGH PRESSURE ALOFT WILL MINIMIZE THE AMOUNT OF AVAILABLE
LIFT…ESPECIALLY IN WESTERN OKLAHOMA AND WESTERN NORTH TEXAS.
ISOLATED THUNDERSTORMS ARE MORE LIKELY TO FORM IN CENTRAL AND
EASTERN OKLAHOMA DURING THE WARMEST PART OF THE AFTERNOON…FROM
ABOUT 2 PM TO 8 PM. WEAK WINDS THROUGHOUT THE ATMOSPHERE WILL RESULT
IN SLOW MOVING AND DISORGANIZED STORMS. MOISTURE AND INSTABILITY
WILL BE SUFFICIENT…HOWEVER…FOR A FEW STORMS TO PRODUCE HEAVY
DOWNPOURS OF RAIN…SMALL HAIL…AND BRIEF GUSTY WINDS. ISOLATED
HAIL AROUND QUARTER SIZE…AND ISOLATED DAMAGING WIND GUSTS ARE
POSSIBLE…ALTHOUGH ORGANIZED SEVERE WEATHER IS NOT EXPECTED.

PROBABILITY TABLE…
VALID THROUGH 700 AM CDT FRIDAY MAY 28.
PROBABILITY OF THUNDERSTORMS OCCURRING IN THE
              NWS NORMAN COUNTY WARNING AREA…20 PERCENT.
PROBABILITY OF SEVERE STORMS IF STORMS OCCUR…10 PERCENT.

OTHER HAZARDOUS WEATHER…
NONE.

.DAYS TWO THROUGH SEVEN…FRIDAY THROUGH WEDNESDAY…

THUNDERSTORM OUTLOOK…
A VERY WEAK COLD FRONT WILL STALL ACROSS OKLAHOMA…ROUGHLY FROM
MCALESTER TO OKLAHOMA CITY TO ALVA. THIS FRONT WILL REMAIN IN PLACE
FRIDAY AND SATURDAY. EASTERLY WINDS TO EITHER SIDE OF THE FRONT WILL
MAINTAIN A SOMEWHAT MOIST UPSLOPE FLOW. ALTHOUGH UPPER LEVEL LIFTING
WILL BE NEARLY ABSENT…STRONG HEATING MAY RESULT IN ISOLATED
AFTERNOON THUNDERSTORMS.

THUNDERSTORM CHANCES WILL INCREASE ACROSS NORTHERN OKLAHOMA ON
SUNDAY…AS A MORE SIGNIFICANT COLD FRONT ARRIVES. LOCALLY HEAVY
RAIN AND ISOLATED SEVERE WEATHER MAY OCCUR ALONG THE FRONT IN
NORTHERN OKLAHOMA LATE SUNDAY. THE COLD FRONT AND ASSOCIATED OUTFLOW
BOUNDARIES MAY BRING HIGHER RAIN CHANCES INTO CENTRAL AND WESTERN
OKLAHOMA SUNDAY NIGHT AND MONDAY. THE FRONT WILL THEN LIFT TOWARD
THE KANSAS BORDER…BUT MAY STILL PRODUCE THUNDERSTORMS IN NORTHERN
OKLAHOMA GOING INTO THE MIDDLE OF NEXT WEEK.
