330 PM CDT THU MAY 31 1990

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR THE REST OF THIS
AFTERNOON THROUGH TONIGHT FOR ALL OF NORTH TEXAS.  THUNDERSTORMS COULD
PRODUCE VERY HEAVY RAIN... LARGE HAIL... DAMAGING WINDS AND POSSIBLY
SMALL... ISOLATED TORNADOES.

LATE THIS AFTERNOON... A WARM FRONT STRETCHED FROM NEAR AMARILLO TO
NORTH OF WICHITA FALLS TO TYLER AND INTO CENTRAL LOUISIANA.  A DRYLINE
STRETCHED FROM AMARILLO TO WEST OF MIDLAND TO MARFA.  THESE TWO
BOUNDARIES... AND ESPECIALLY THE WARM FRONT... ARE EXPECTED TO BE THE
FOCUS FOR THUNDERSTORM ACTIVITY.

VERY UNSTABLE ATMOSPHERIC CONDITIONS PERSIST ACROSS NORTH TEXAS
WITH DEWPOINTS IN THE MIDDLE TO UPPER 70S.  AFTERNOON HEATING INTO THE
MIDDLE 90S ALONG WITH ABUNDANT MOISTURE HAVE PRODUCED LIFTED INDICES
OF MINUS 9 TO MINUS 12.

THUNDERSTORMS IN THE EASTERN HALF OF NORTH TEXAS HAVE BEEN BUILDING
ALONG THE WARM FRONT IN THE AREA AND ON OUTFLOW BOUNDARIES LEFT FROM
EARLIER CONVECTION.  THUNDERSTORMS SHOULD CONTINUE THROUGH TONIGHT
ACROSS NORTH CENTRAL AND NORTHEAST TEXAS WHERE MOISTURE CONVERGENCE
WILL BE GREATEST ALONG THE WARM FRONT AND THE OUTFLOW BOUNDARIES.
ALSO... A WEAK UPPER LEVEL IMPULSE PUSHING ACROSS NORTHERN MEXICO
IS EXPECTED TO MOVE OVER NORTH TEXAS TONIGHT AND FURTHER AID THE
ACTIVITY.

IN WESTERN SECTIONS OF NORTH TEXAS... THUNDERSTORMS COULD DEVELOP
ALONG THE DRYLINE AS A WEAK IMPULSE MOVES ACROSS THE SOUTHERN ROCKIES
THIS EVENING.  ISOLATED SEVERE THUNDERSTORMS ARE POSSIBLE IN WESTERN
SECTIONS OF NORTH TEXAS EARLY TONIGHT.  ONE LIMITING FACTOR WILL BE
A STRONG MID-LEVEL CAP COULD INHIBIT THUNDERSTORMS DEVELOPMENT.

STORM SPOTTERS AND EMERGENCY MANAGEMENT OFFICIALS ACROSS NORTH TEXAS
SHOULD KEEP ABREAST OF THE LATEST WEATHER CONDITIONS AND BE PREPARED
