AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
805 PM CST THU MAR 30 2006

.MESOSCALE UPDATE...
THE SUPERCELL MOVING INTO LE FLORE COUNTY HAS DEVELOPED A DEEP
CYCLONICALLY CURVED INFLOW REGIME.  IT IS THIS FEATURE THAT IS
RESULTING IN THE BRIGHT INBOUND / OUTBOUND RADAR VELOCITY COUPLET
AND NOT A MESOCYCLONE.  THIS FEATURE IS CAN BE SEEN IN THE
INFLOW REGION OF THE REFLECTIVITY AND NOT IN THE MAIN UPDRAFT.
RAPID TORNADOGENESIS CAN OCCUR IF THE REAR FLANK DOWNDRAFT CAN
PUNCH FORWARD...BUT THE VEOLICITY SIGNATURE ITSELF SHOULD BE
INTERPRETED AS AN AREA OF HIGH VORTICITY AND NOT THE MESOCYCLONE.
FOR RADAR TRACKING PURPOSES THE MOST DANGEROUS PART OF THE STORM
IS BACK IN THE REFLECTIVITY HOOK AND NOT WITH THE HIGH-VELOCITY
SIGNATURE FORWARD OF THE HOOK.

DISCUSSION...
STRONG TO SEVERE THUNDERSTORMS HAVE DEVELOP EARLY THIS AFTERNOON
ACROSS CENTRAL OKLAHOMA...ALONG AN EASTWARD MOVING DRY LINE. THE DRY
LINE IS FORECAST TO MOVE INTO PORTIONS OF NORTHEAST OKLAHOMA BETWEEN

ENHANCED TORNADO THREAT WILL BE LIKELY WITH ANY DISCRETE STORMS.

THE THUNDERSTORM ACTIVITY IS EXPECTED TO BECOME MORE LINEAR AND
WIDESPREAD WITH TIME...WITH A LINE OF SEVERE THUNDERSTORMS SWEEPING
THROUGH THE REMAINDER OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS
THIS EVENING INTO THE OVERNIGHT HOURS. THE PRIMARY THREAT WITH THESE
STORMS WILL BE LARGE HAIL AND DAMAGING WINDS. AN ISOLATED TORNADO
THREAT WILL CONTINUE OVERNIGHT WITH ANY EMBEDDED SUPERCELL
STRUCTURES WITHIN THE MAIN THUNDERSTORM LINE. THE SEVERE WEATHER
THREAT IS EXPECTED TO END AFTER MIDNIGHT WITH THE LINE OF STORMS
SHIFTING EAST OF NORTHWEST ARKANSAS.

IN ADDITION TO THE SEVERE WEATHER THREAT...STRONG SOUTHERLY SURFACE
WINDS WILL DEVELOP OVER THE AREA TODAY WITH SUSTAINED WINDS OF
15 TO 25 MILES AN HOUR...AND NUMEROUS GUSTS TO 40 MILES AN HOUR OR
GREATER. PLEASE REFER TO THE WIND ADVISORY ISSUED FOR THE AREA FOR
ADDITIONAL DETAILS. THE STRONG WINDS...COMBINED WITH WARM
TEMPERATURES AND VERY DRY VEGETATION WILL ALSO RESULT IN VERY
DANGEROUS FIRE WEATHER CONDITIONS CONTINUING OVER THE REGION TODAY.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION WILL BE NEEDED THIS AFTERNOON INTO TONIGHT.
NUMEROUS WARNINGS WILL LIKELY BE ISSUED ACROSS A LARGE PORTION OF
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS THIS AFTERNOON INTO TONIGHT.

APPEARS ANOTHER ROUND OF SEVERE WEATHER WILL BE POSSIBLE ON SUNDAY.

FIRE WEATHER WILL ALSO REMAIN A CONCERN THROUGH THE WEEKEND AND
THE FIRST PART OF NEXT WEEK...UNLESS SIGNIFICANT RAIN OCCURS OVER THE
