1000 AM CST MON FEB 24 1992

VALLEY WEATHER IS POTENTIALLY EXPLOSIVE.

FORECASTERS SPECIALIZING IN SEVERE WEATHER TOOK A CLOSE LOOK AT EARLY
MORNING DATA AND DECIDED THAT CHANCES FOR SEVERE THUNDERSTORMS OVER
PORTIONS OF SOUTH AND DEEP SOUTH TEXAS WERE SIGNIFICANT. THEY LOOKED AT
HOW BOYANT AIR WAS..HOW WARM IT WAS..WHETHER IF AIR CONVERGED IN THE LOW
LEVELS..IT WOULD OUTFLOW ALOFT..WHETHER OR NOT THERE WAS A COLD FRONT IN
THE VICINITTY..HOW MOIST THE AIR WAS..AND OTHER FACTORS AS WELL. MANY
SEVERE WEATHER PARAMETERS WERE IN PLACE..SO WEATHER BEARS CLOSE WATCH
TODAY AND TONIGHT.

AT LATE MORNING..RADAR INDICATED SHOWER AND THUNDERSTORM DOMINANT OVER
MUCH OF THE STATE NORTEAST OF DEL RIO. A SEVERE THUNDERSTORM WATCH WAS
IN EFFECT THERE BECAUSE OF THE STORMS. LATER THIS AFTERNOON AND EVENING
CHANCES ARE FAIR THAT THE SEVERE WEATHER NOW NORTHWEST MIGHT SHIFT MORE
TO THE EAST AND SOUTH TOWARD US. WEATHER HERE BEARS CLOSE WATCH IN
THE HOURS TO COME BECAUSE OF THE POSSIBILITY.

AS A FRONT TO THE NORTHWEST HELPING CAUSE THE SEVERE WEATHER PASSES
TONIGHT..COLDER TEMPERATURES WILL FOLLOW. READINGS UPSTATE ARE 20 TO 30
DEGREES COLDER THAN 24 HOURS BEFORE. SHARP COOLING IS EXPECTED HERE
BEHIND THE FRONT..TOO.

HIGH TEMPERATURES YESTERDAY WERE IN THE 70S..TEMPERATURES AT DAYBREAK
WERE IN THE 60S AND 70. ONES IN THE 40S ARE LIKELY BEHIND THE FRONT.
RAINFALL HAS BEEN SLIGHT THE PAST 24 HOURS..BUT COULD BE MEASURED
IN INCHES SOON.

STRONG WIND IS ANOTHER WEATHER ELEMENT THAT BEARS WATCH UNTIL MORE
SETTLED CONDITIONS ARRIVE.
