SEVERE WEATHER OUTLOOK FOR NORTH TEXAS
NATIONAL WEATHER SERVICE FORT WORTH TX
455 AM CST SUN MAR 11 1990

AN OUTBREAK OF SEVERE THUNDERSTORMS IS EXPECTED TODAY OVER PARTS OF
NORTH TEXAS. LARGE HAIL...DAMAGING WINDS AND A FEW TORNADOES WILL BE
POSSIBLE. LOCALLY HEAVY RAINFALL WILL ALSO BE A THREAT OVER THE
CENTRAL AND WESTERN PARTS OF NORTH TEXAS.

THE GREATEST THREAT OF SEVERE THUNDERSTORMS WILL BE OVER THE CENTRAL
AND WESTERN PART NORTH CENTRAL TEXAS...WITH A LESSER RISK OVER EAST
TEXAS.

STRONG LOW LEVEL SOUTHERLY WINDS HAVE BROUGHT WARM AND MOIST AIR INTO
NORTH TEXAS. MEANWHILE...A VIGOROUS UPPER AIR LOW PRESSURE TROUGH WILL
BE MOVING ACROSS NORTHWEST TEXAS TODAY...RESULTING IN A VERTICAL WIND
PROFILE FAVORABLE FOR SEVERE THUNDERSTORMS...AND TORNADOES.

EARLY SUNDAY MORNING...WIDESPREAD SHOWERS AND THUNDERSTORMS WERE
OCCURRING OVER MUCH OF THE WESTERN HALF OF NORTH TEXAS. STRONG
THUNDERSTORMS WERE ALSO OCCURRING IN WEST TEXAS...AHEAD OF A
DRYLINE...THAT WAS BEGINNING TO SURGE EASTWARD OUT OF NEW MEXICO. AS
THE UPPER TROUGH...AND ASSOCIATED DRYLINE APPROACHES...SOME OF
THUNDERSTORMS IN NORTH TEXAS ARE EXPECTED TO BECOME SEVERE LATER THIS
MORNING...AND THROUGH THE AFTERNOON.

AN INHIBITING FACTOR FOR SEVERE STORMS WAS THE PRESENCE OF WIDESPREAD
CLOUD COVER OVER TEXAS. HOWEVER THIS MAY BE OVERCOME BY THE STRONG
DYNAMICS ASSOCIATED WITH THE UPPER TROUGH...AND THE POSSIBILITY OF
SURFACE HEATING WEST OF THE DRYLINE LATER TODAY.

SPOTTERS IN THE CENTRAL AND WESTERN PARTS OF NORTH TEXAS CAN EXPECT
ACTIVATION THROUGH THE DAY...WHILE THOSE IN THE EAST MAY REQUIRE
ACTIVATION THIS AFTERNOON.
