SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
340 PM CDT WED MAY 30 1990

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER THE NORTH CENTRAL
AND NORTHEASTERN SECTIONS OF NORTH TEXAS.  THE RISK AREA IS GENERALLY
EAST AND NORTH OF A LINE FROM BONHAM TO KAUFMAN TO LONGVIEW TO
MARSHALL.

THUNDERSTORMS IN SOUTHEASTERN OKLAHOMA THIS AFTERNOON PRODUCED AN
OUTFLOW BOUNDARY WHICH WAS SITUATED FROM CENTRAL OKLAHOMA NEAR
OKLAHOMA CITY TO ALONG THE RED RIVER IN SOUTHEAST OKLAHOMA.  IN TEXAS...
A DRYLINE... A BOUNDARY SEPARATING DRY AIR TO THE WEST FROM MOIST AIR
TO THE EAST STRETCHED FROM EAST OF WICHITA FALLS TO EAST OF ABILENE TO
NEAR DEL RIO.

SOUTHERLY WINDS ACROSS THE EASTERN HALF OF TEXAS CONTINUED TO BRING
MOISTURE INTO THE RISK AREA... RAISING DEWPOINTS TO THE LOWER AND
MIDDLE 70S.  THE ATMOSPHERE IS MODERATELY UNSTABLE WITH LIFTED INDICES
BETWEEN MINUS 6 AND MINUS 9 ACROSS THE AREA.

THUNDERSTORM DEVELOPMENT IS EXPECTED NEAR THE INTERSECTION OF THE
DRYLINE AND THE OUTFLOW BOUNDARY IN OKLAHOMA WHERE MOISTURE CONVERGENCE
WILL BE GREATEST.  CONVECTION COULD THEN SPREAD INTO NORTH CENTRAL AND
NORTHEAST TEXAS LATER THIS EVENING.

STRONGER THUNDERSTORMS COULD PRODUCE HEAVY RAIN... HAIL AND DAMAGING
STRAIGHT LINE WINDS.

LIMITING FACTORS TO THUNDERSTORM DEVELOPMENT ARE WARM MID-LEVEL
TEMPERATURES OVER NORTH TEXAS AND FORECASTED WEAKENING OF MID-LEVEL
WIND FLOW... WHICH WILL ACT TO SLOW OR STOP MOVEMENT OF DRYLINE.

STORM SPOTTERS AND EMERGENCY MANAGEMENT PERSONNEL WILL WANT TO MONITOR
THE DEVELOPMENT OF THIS WEATHER SITUATION.  LIMITED STORM SPOTTER
ACTIVATION MAY BE REQUIRED ACROSS THE PARTS OF NORTH CENTRAL AND
NORTHEAST TEXAS LATE THIS AFTERNOON AND THIS EVENING.
