1200 PM CDT TUE JUN 6 1989

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS OVER MUCH OF SOUTHERN
AND WESTERN OKLAHOMA THIS AFTERNOON AND TONIGHT...SOUTH AND WEST OF A
LINE FROM BEAVER TO OKLAHOMA CITY TO THE RED RIVER 15 MILES SOUTHWEST
OF HUGO. THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER THE
REMAINDER OF THE STATE. IN ADDITION A FLASH FLOOD WATCH CONTINUES
IN EFFECT TONIGHT FOR EXTREME SOUTHERN OKLAHOMA.

A RIDGE OF HIGH PRESSURE AT THE SURFACE EXTENDS FROM THE MIDDLE
MISSISSIPPI VALLEY TO NORTHEAST TEXAS TODAY...TO THE WEST OF THIS
RIDGE INCREASING SOUTHERLY LOW LEVEL WIND IS BRINGING MOISTURE
RAPIDLY NORTHWARD FROM SOUTHERN TEXAS. WITH THIS INCREASING LOW LEVEL
MOISTURE THE ATMOSPHERE OVER WESTERN OKLAHOMA IS BECOMING MORE UNSTABLE
AND THUNDERSTORMS REACHED SEVERE LEVELS IN NORTHWESTERN OKLAHOMA BY LATE
MORNING.

THE DRYLINE AT MIDDAY REMAINS WELL TO THE WEST IN EASTERN NEW MEXICO...
HOWEVER A A STRONG UPPER LEVEL TROUGH MOVING THROUGH THE SOUTHERN
ROCKIES TODAY IS EXPECTED TO PUSH THE DRYLINE EASTWARD TO THE CENTRAL
TEXAS PANHANDLE BY EVENING. THE THUNDERSTORMS PRESENTLY IN NORTHWEST
OKLAHOMA MAY CONTINUE TO BE SEVERE THIS AFTERNOON. IN ADDITION OTHER
SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP EAST OF THE DRYLINE IN THE
TEXAS PANHANDLE LATER THIS AFTERNOON AND SPREAD EASTWARD INTO WESTERN
OKLAHOMA.

AS THE UPPER LEVEL TROUGH MOVES INTO THE STATE LATER TONIGHT HEAVY
RAINS ARE POSSIBLE...WITH THE FORECAST TRACK OF THE UPPER LOW
SUGGESTING THE GREATEST THREAT OF HEAVY RAIN WILL BE IN THE SOUTH.
A FLASH FLOOD WATCH CONTINUES FOR TONIGHT ACROSS EXTREME SOUTHERN
OKLAHOMA...THAT PORTION SOUTH OF A LINE FROM VINSON TO PAULS VALLEY
TO SMITHVILLE.

SEVERE THUNDERSTORMS ARE ALREADY IN PROGRESS IN NORTHWEST OKLAHOMA
AND SPOTTER GROUPS IN THE REMAINDER OF WESTERN OKLAHOMA SHOULD
PREPARE FOR POSSIBLE ACTIVATION LATER THIS AFTERNOON.
