AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
433 AM CDT THU MAY 12 2005

.DISCUSSION...
THE MAIN FOCUS OF THE FORECAST WILL BE THE NEXT COUPLE OF DAYS AS
TSTM CHANCES WILL BE INCREASING. A COLD FRONT MOVING THROUGH
SOUTHWEST KANSAS AND THE OKLAHOMA PANHANDLE STILL HAS DECENT
PRESSURE RISES OCCURRING BEHIND IT EARLY THIS MORNING. THUS... THE
FRONT IS EXPECTED TO MOVE INTO OUR NORTHWEST OKLAHOMA ZONES THIS
MORNING BEFORE BECOMING STATIONARY...AND WEAKENING... LATER TODAY. A
COUPLE SHWRS/TSTMS WILL BE POSSIBLE IN THE FAR NORTHWEST NEAR THE
FRONT THROUGH MID MORNING. TSTM CHANCES EXPECTED TO INCREASE LATE
TODAY AND TONIGHT... ESPECIALLY ACROSS ABOUT THE NORTHWEST THIRD OF
OKLAHOMA. UPPER SUPPORT EXPECTED TO INCREASE OVER THE REGION BY LATE
TODAY AS THE AREA COMES UNDER THE INFLUENCE OF THE RIGHT ENTRANCE
REGION OF THE UPPER JET MAX CENTERED OVER THE CENTRAL PLAINS.
INSTABILITIES AND DEEP LAYER SHEAR ARE EXPECTED TO BE SUFFICIENT TO
SUPPORT SOME SEVERE TSTMS LATE THIS AFTERNOON AND TONIGHT.
MEANWHILE... IF THIS MORNINGS FRONT CAN MAINTAIN SOME IDENTITY
THROUGH LATE TODAY... IT COULD ALSO ACT A FOCUS FOR TSTM
DEVELOPMENT. AS THE LOW LEVEL JET AND WARM ADVECTION INCREASES
TONIGHT OVER NORTHERN OKLAHOMA... WE COULD SEE LOCALLY HEAVY
RAINFALL ACROSS THE REGION. AGAIN... ANY AVAILABLE LOW LEVEL
BOUNDARIES COULD HELP TO FOCUS THE HEAVIER RAINFALL AMOUNTS.

A COLD FRONT IS EXPECTED TO MAKE A MORE SUBSTANTIAL PUSH SOUTH
ACROSS THE AREA ON FRIDAY AS THE MAIN UPPER TROUGH AXIS BEGINS TO
PUSH INTO THE PLAINS. THE FRONT SHOULD MOVE THROUGH NORTHWEST
OKLAHOMA BY MIDDAY... LIKELY STRETCHING FROM NORTH CENTRAL INTO
SOUTHWEST OKLAHOMA BY EARLY FRIDAY EVENING. TSTMS ARE EXPECTED
ALONG AND NORTH OF THE FRONT... HOWEVER... MESOSCALE FEATURES...
IN THE FORM OF BOUNDARIES REMAINING FROM THE OVERNIGHT
CONVECTION... COULD SIGNIFICANTLY AFFECT THE SHWR/TSTM
DISTRIBUTION. THE FRONT SHOULD MOVE THROUGH ABOUT ALL OF THE AREA
BY SATURDAY MORNING WITH ALL PCPN BEING OUT OF THE SOUTHERN PART
OF THE AREA BY LATE SATURDAY.

ISENTROPIC LIFT EXPECTED TO DEVELOP OVER THE WESTERN PART OF THE
AREA BY LATE SUNDAY. WILL LEAVE IN LOW POPS FOR NOW ACROSS THE
SOUTHWEST SECTIONS WHERE MOISTURE MIGHT BE A LITTLE HIGHER TO
SUPPORT A FEW ELEVATED SHWRS/TSTMS. WILL MAINTAIN A SLIGHT CHANCE
FOR TSTMS ACROSS THE NORTH FOR TUES/WED FOR WEAK UPPER WAVES MOVING
AROUND THE NORTH SIDE OF THE UPPER RIDGE. HOWEVER... AS THE RIDGE
BUILDS NORTH THROUGH ALL OF THE AREA BY SECOND HALF OF THE WEEK...
DRY/WARM WEATHER WILL PREVAIL AREAWIDE.
