EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
950 PM CDT FRI JUL 28 2000

WELL DEFINED VORTICITY MAXIMUM CENTERED NEAR WICHITA AT THIS TIME
WILL MOVE SOUTHEAST ACROSS EASTERN OKLAHOMA AND WESTERN ARKANSAS
TONIGHT AND EARLY SATURDAY. EARLIER SQUALL LINE IN SOUTHERN KANSAS
HAS DISSIPATED BUT ISOLATED LARGE SEVERE STORMS HAVE DEVELOPED ALONG
THE OUTFLOW BOUNDARY IN NORTH CENTRAL OKLAHOMA. HASKELL PROFILER HAS
TAKEN ON QUITE AN IMPRESSIVE LOOK DURING THE PAST FEW HOURS AND FLOW
LOOKS JUST SUFFICIENT TO SUPPORT SUPERCELLULAR STORMS SUCH AS THE
ONE CURRENTLY IN NOBLE COUNTY. APPEARS THIS STORM IS MOVING HARD
RIGHT AND MAY STAY WEST OF OUR FORECAST AREA. INSTABILITY AXIS RUNS
FROM WEST TO SOUTH OF TULSA SO STILL A CHANCE FOR AN ISOLATED
SUPERCELL TO FORM OVER THE NEXT FEW HOURS SOMEWHERE IN THE
CREEK/OKFUSKEE/OKMULGEE/MCINTOSH COUNTIES AREA.

SHOWERS AND STORMS STARTING TO INCREASE AS WELL FURTHER EAST AND
THIS TREND IS LIKELY TO CONTINUE. IT LOOKS LIKE MOST ALL OF
NORTHWEST ARKANSAS AND SOUTHEAST OKLAHOMA WILL SEE RAIN OVERNIGHT
BUT AREAS NORTHWEST OF INTERSTATE 44 MAY NOT SEE MUCH AT ALL. STORMS
FURTHER EAST SHOULD BE MULTICELLULAR IN NATURE WITH MAYBE A MARGINAL
SEVERE WIND/HAIL THREAT IN A STORM OR TWO. POTENTIAL FOR HEAVY
RAINFALL STILL EXISTS MAINLY IN NORTHWEST ARKANSAS AND FAR EASTERN
OKLAHOMA SO WILL CONTINUE TO MENTION THIS IN THE ZONEHS.

WILL UPDATE SHORTLY TO ADD THE NEW SEVERE THUNDERSTORM WATCH AND TO
MAKE A FEW OTHER FIRST PERIOD CHANGES BASED ON CURRENT TRENDS.

.TUL...
AR...NONE.
OK...NONE.
