SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FT WORTH TX
350 PM CST THU FEB 1 1990

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS OVER THE SOUTHEAST
ONE THIRD OF NORTH TEXAS FOR THE REMAINDER OF THIS AFTERNOON AND
TONIGHT. THE AREA OF MODERATE RISK IS GENERALLY SOUTHEAST OF A LINE
FROM PARIS TO CORSICANA TO LAMPASAS. THIS INCLUDES THE CITIES OF
TYLER...LONGVIEW...LUFKIN...WACO AND TEMPLE.

AT MID AFTERNOON THUNDERSTORMS WERE CONTINUING FROM SOUTHWEST
ARKANSAS AND NORTHWEST LOUISIANA SOUTH TO THE HOUSTON AREA IN
SOUTHEAST TEXAS. A RAIN-COOLED BOUNDARY EXTENDED FROM THE HOUSTON
AREA WEST TO NEAR AUSTIN. ADDITIONAL THUNDERSTORMS WERE DEVELOPING
AT MID AFTERNOON OVER PARTS OF SOUTH CENTRAL TEXAS... FROM LAMPASAS
SOUTH TO THE HILL COUNTRY.... DUE IN PART TO A STRONG UPPER LEVEL
SYSTEM MOVING ACROSS THE REGION. SOME SMALL HAIL HAS BEEN REPORTED
WITH SOME OF THE THUNDERSTORMS IN THE HILL COUNTRY...AND A TORNADO
WAS REPORTED NEAR COTULLA.

THE BEST CHANCES FOR SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT
EXIST ALONG AND NEAR THE RAIN-COOLED BOUNDARY OVER THE SOUTH PART OF
NORTH CENTRAL AND NORTHEAST TEXAS...DUE IN PART TO THE STRONGER INFLOW
AND HIGHER MOISTURE CONTENT AVAILABLE IN THAT REGION. THE STRONG UPPER
LEVEL SYSTEM WILL TEND TO ENHANCE THUNDERSTORM DEVELOPMENT ALONG THIS
BOUNDARY. THUS A TORNADO WATCH HAS BEEN ISSUED UNTIL 900 PM FOR
PARTS OF CENTRAL AND EAST TEXAS.

IN NORTH CENTRAL TEXAS...THE WATCH INCLUDES FREESTONE...ANDERSON...
AND CHEROKEE COUNTIES.

OVER THE NORTH PART OF NORTH CENTRAL TEXAS...THE RAIN-COOLED AIR LEFT
OVER FROM THE PASSAGE OF THUNDERSTORMS THIS MORNING OFFERS A LESS
FAVORABLE ENVIRONMENT FOR SEVERE THUNDERSTORMS. SOME THUNDERSTORMS
COULD PRODUCE SMALL HAIL OVER THE NORTH PARTS OF NORTH CENTRAL AND
NORTHEAST TEXAS DUE TO THE STRENGTH OF THE UPPER LEVEL SYSTEM.
BRIEF HEAVY RAINS COULD ALSO OCCUR...AND A FLASH FLOOD WATCH
REMAINS IN EFFECT FOR TONIGHT FOR MUCH OF THE EASTERN THIRD OF NORTH
TEXAS.

SPOTTERS AND EMERGENCY MANAGEMENT OFFICIALS OVER NORTHEAST TEXAS
WILL WANT TO KEEP IN TOUCH WITH LATEST WEATHER DEVELOPEMENTS TONIGHT.
