AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
325 AM CDT WED OCT 10 2001

ANOTHER ACTIVE WX DAY EXPECTED TODAY. ANOTHER IN A LINE OF UPPER
LEVEL DISTURBANCES MOVING ACROSS THE COUNTRY MAKES ITS WAY ACROSS
THE CENTRAL AND SOUTHERN PLAINS TODAY INTO TONIGHT. THIS WAVE WILL
HELP TO DRIVE A COLD FRONT...WHICH HAS ALREADY MOVED INTO NW
OKLAHOMA EARLY THIS MORNING...ACROSS THE AREA. ALTHOUGH SOME
ACTIVITY COULD OCCUR EARLY THIS MORNING. THINK MUCH MORE WILL
DEVELOP LATER TODAY AS WE GET SOME HEATING. STILL PLENTY OF LOW
LEVEL MOISTURE AVAILABLE AND ALONG WITH UPPER LEVEL SUPPORT...SEVERE
POTENTIAL WILL AGAIN BE PRESENT TODAY. MAINLY ACROSS CENTRAL AND
SOUTHERN/SOUTHEASTERN SECTIONS TODAY INTO TONIGHT. WIND FIELDS NOT
AS STRONG AS YESTERDAY...BUT ARE STILL HEALTHY ENOUGH TO CAUSE SOME
CONCERN FOR A FEW SUPERCELLS AND POSSIBLE AN ISOLATED TORNADO.
CURRENTLY THINK WITH ORIENTATION OF FRONT AND LOW/ MID LEVEL WIND
FIELDS THIS AFTN AND EVENING...MAIN THREATS WILL BE HAIL AND HEAVY
RAIN.

FRONT SHOULD CLEAR THE STATE THIS EVENING WITH A GRADUAL SHIFTING OF
PRECIP SOUTH AND EAST OF AREA OVERNIGHT...AS UPPER WAVE MOVES TO THE
EAST.

THURSDAY SHOULD BE A DRY DAY WITH PLEASANT TEMPS AND LOWER
HUMIDITIES. FOCUS THEN TURNS TO ANOTHER BATCH OF ENERGY DROPPING SE
INTO CENTRAL ROCKIES WITH ANOTHER DEVELOPING COLD FRONT WHICH WILL
ENTER NW OKLAHOMA EARLY FRI. THIS SYSTEM SHOULD BE HURTING FOR
MOISTURE...BUT DOES SHOW POSSIBILITY OF SOME PRECIP BY FRI AFTN AND
EVENING ACROSS AREA. CURRENT PACKAGE HAS CHANCE POPS AND WILL LEAVE
IT THAT WAY. FRI COULD TURN QUITE COOL BY LATE IN THE DAY WITH
DESCENT CAA AND BRISK NORTH WINDS BEHIND BOUNDARY. CURRENT AVN STILL
SHOWS UPPER WAVE TRIES TO WRAP UP AND CLOSE OFF ON SAT JUST EAST OF
US. WILL THEREFORE KEEP SOME LOW POPS CENTRAL AND EAST FOR AT LEAST
MORNING HOURS. THIS SYSTEM LIFTS OUT LATE SAT AS A KICKER DRIVES
E/SE ACROSS CENTRAL PLAINS ON SUN. THIS SHOULD REMAIN TO OUR NORTH
WITH DRY CONDITIONS CONT...BUT LOOKS TO PUSH SOME REINFORCING COOL
AIR SOUTH ACROSS OKLAHOMA. INTO EARLY NEXT WEEK NEW MRF SHOWS DRY
CONDITIONS CONT WITH WARMING TEMPS.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TODAY AND TONIGHT
ACROSS PORTIONS OF CENTRAL AND SOUTHERN OKLAHOMA...AND MUCH OF
WESTERN NORTH TEXAS. THE SLIGHT RISK AREA COVERS LOCATIONS NEAR AND
SOUTH OF A LINE EXTENDING FROM CROWELL AND VERNON TEXAS...TO
CHICKASHA...TO CHANDLER. THIS SLIGHT RISK AREA INCLUDES THE CITIES
OF WICHITA FALLS...LAWTON...OKLAHOMA CITY...ARDMORE...AND ADA. THE
PRIMARY THREATS FROM ANY SEVERE WEATHER WILL BE LARGE HAIL...
DAMAGING WIND GUSTS...AND FLOODING RAINFALL.

A COLD FRONT WILL MOVE SOUTHEAST ACROSS OKLAHOMA AND WESTERN NORTH
TEXAS TODAY AND TONIGHT. EARLY THIS MORNING...THE COLD FRONT
EXTENDED FROM NORTH CENTRAL OKLAHOMA...SOUTHWESTWARD INTO SOUTHWEST
OKLAHOMA AND PORTIONS OF WESTERN NORTH TEXAS. ALTHOUGH AMPLE
MOISTURE AND MODERATE INSTABILITIES WILL ONCE AGAIN EXIST ACROSS THE
AREA TODAY AND INTO TONIGHT...VERTICAL WIND SHEAR PROFILES WILL BE
WEAKER THAN THOSE SEEN ON TUESDAY. THUS...THE THREAT OF TORNADIC
