EASTERN OKLAHOMA/NORTHWEST ARKANSAS HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
600 AM CST SAT MAR 7 1998

A FEW SEVERE THUNDERSTORMS ARE EXPECTED ACROSS EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS TODAY.

A MAJOR STORM SYSTEM MOVING OUT OF THE SOUTHERN ROCKIES THIS MORNING
WILL MOVE ACROSS THE SOUTHERN PLAINS TODAY AND TONIGHT.  EARLY THIS
MORNING SHOWERS AND THUNDERSTORMS HAD BECOME WIDESPREAD FROM PARTS OF
CENTRAL AND WESTERN OKLAHOMA DOWN INTO TEXAS.  THE SHOWERS AND
THUNDERSTORMS WILL CONTINUE TO INCREASE IN COVERAGE IN ADVANCE OF THE
STORM SYSTEM AND WILL BE SPREADING OVER EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS DURING THE MORNING.

A STRONG AREA OF LOW PRESSURE WILL DEEPEN OVER SOUTHEAST COLORADO AND
NORTHEAST NEW MEXICO THIS MORNING.  THE LOW PRESSURE SYSTEM WILL TRACK

LIFTING NORTHWARD ACROSS THE AREA.  MEANWHILE...COLDER TEMPERATURES
ALOFT ASSOCIATED WITH THE UPPER LEVEL STORM SYSTEM WILL ALSO BE
SPREADING OVER THE REGION WITH THE ATMOSPHERE BECOMING INCREASING
UNSTABLE.

THE MOST LIKELY AREA FOR SEVERE WEATHER WILL BE IN AREAS MAINLY TO THE
SOUTH OF I-40...BUT ISOLATED SEVERE STORMS WILL ALSO BE POSSIBLE
ELSEWHERE.  LARGE HAIL WILL BE THE MAIN THREAT...BUT THE VERTICAL WIND
PROFILE COULD SUPPORT THE DEVELOPMENT OF ISOLATED SUPERCELLS SOUTH OF
I-40...WITH A THREAT FOR TORNADOES.  ALTHOUGH AN ISOLATED SEVERE
THUNDERSTORM CAN NOT BE TOTALLY RULED OUT THIS MORNING...THE MAIN THREAT
WILL RUN FROM AROUND MIDDAY INTO THE EARLY EVENING HOURS.

IN ADDITION TO THE THREAT OF SEVERE WEATHER TODAY...THERE IS THE
POSSIBILITY OF SOME SNOW ACROSS THE AREA LATE TONIGHT AND SUNDAY AS THE
POWERFUL STORM SYSTEM EXITS THE AREA.  A VERY DANGEROUS WINTER STORM IS
FORECAST ACROSS KANSAS DOWN INTO NORTHWESTERN OKLAHOMA BY LATER TONIGHT.
IN NORTHEAST OKLAHOMA THE PRECIPITATION WILL LIKELY CHANGE OVER TO SNOW
MAINLY IN AREAS TO THE NORTH AND WEST OF I-44 BY MORNING.  HOWEVER...ANY
MAJOR ACCUMULATIONS OF SNOW AT THIS TIME WOULD APPEAR TO REMAIN FOCUSED
FURTHER OFF TO THE NORTH AND WEST.  IN ADDITION TO THE POSSIBILITY OF
SNOW...VERY STRONG NORTH TO NORTHWESTERLY WINDS ARE ALSO EXPECTED TO
SPREAD INTO THE AREA LATE TONIGHT AND EARLY SUNDAY.  GUSTY WINDS IN
EXCESS OF 30 MILES AN HOUR WILL BE POSSIBLE OVER MUCH OF EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS DURING THE DAY ON SUNDAY WITH FALLING
