SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FT WORTH TX
6 00 AM CDT WED MAY 2 1990

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS TODAY AND TONIGHT
ACROSS A LARGE PART OF NORTH TEXAS..GENERALLY EAST OF A WICHITA
FALLS..BRADY LINE. THE MAIN THREAT FROM THESE THUNDERSTORMS LATER
TODAY AND TONIGHT WILL BE FROM LARGE HAIL AND DAMAGING WINDS..HOWEVER
ISOLATED TORNADOES MAY ALSO OCCUR.

IN ADDITION TO THE SEVERE WEATHER THREAT..THERE REMAINS THE POTENTIAL
FOR ADDITIONAL HEAVY RAINS..WITH WIDESPREAD RAIN AMOUNTS OF 2 TO 4
INCHES POSSIBLE BY THURSDAY MORNING IN THE RISK AREA.

AN UPPER LEVEL LOW OVER ARIZONA WILL MOVE EAST TODAY. AS IT DOES..
CONDITIONS WILL DESTABILIZE ALOFT AS A RESULT OF INCREASED UPPER
DIFLUENCE AND COLDER AIR. AT THE SURFACE..A QUASI STATIONARY FRONT
EXTENDS ACROSS NORTHEAST SOUTHWESTWARD INTO SOUTH CENTRAL TEXAS THIS
MORNING. THIS FRONT WILL BEGIN TO MOVE SLOWLY NORTHWARD LATER TODAY..
MOVING INTO NORTH CENTRAL TEXAS BY SUNSET. AS THE UPPER LOW EDGES
INTO WEST TEXAS LATE THIS AFTERNOON..DESTABILIZATION WILL OCCUR..AND
THE RESULTING STRONG CONVECTION WILL FOCUS ALONG THE FRONT..WHICH
WILL EXTEND ACROSS THE EASTERN TWO-THIRDS OF NORTH TEXAS. FAVORABLE
LOW LEVEL SHEARS AND ENHANCED UPPER LEVEL DIFLUENCE WILL CAUSE
THUNDERSTORMS TO INTENSIFY RAPIDLY..MANY REACHING SEVERE LEVELS LATER
TODAY AND TONIGHT. DUE TO THE FAVORABLE LOW LEVEL WIND SHEARS
EXPECTED..AN ISOLATED TORNADO OR TWO CANNOT BE RULED OUT IN THE RISK
AREA.

NOT ONLY IS THERE A POSSIBILITY OF SEVERE THUNDERSTORMS...BUT HEAVY
RAINFALL IS ALSO POSSIBLE.

BECAUSE OF THE PRONOUNCED UPPER DIFFLUENCE EXPECTED AND ABUNDANT RICH
GULF MOISTURE PRESENT..HEAVY RAINS ARE INEVITABLE. VERY HEAVY RAINS
THAT FELL LAST NIGHT AND EARLY THIS MORNING ACROSS NORTH CENTRAL AND
NORTHEAST TEXAS HAVE EXACERBATED AN ALREADY SERIOUS FLOOD THREAT.
GROUNDS ARE TOTALLY SATURATED ACROSS A LARGE PORTION OF THE RISK
AREA..WITH NUMEROUS RIVERS...STREAMS...AND LAKES NEAR OR ABOVE BANKFULL
WITH ALL AREA LAKES AT OR VERY NEAR THEIR EMERGENCY SPILLWAY. THIS
IS DEVELOPING INTO A VERY DANGEROUS FLOOD SITUATION.

EMERGENCY MANAGEMENT OFFICIALS AND PERSONS LIVING IN LOW LYING...FLOOD
PRONE AREAS IN THE RISK AREA...SHOULD KEEP ALERT OF THIS DEVELOPING
HEAVY RAIN AND SEVERE WEATHER THREAT.
