HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
645 PM CST SUN JAN 28 2001

...STRONG TO SEVERE THUNDERSTORMS WITH LOCALLY HEAVY RAINS ARE
EXPECTED TO DEVELOP ACROSS SOUTH CENTRAL TEXAS THIS EVENING...

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS LATE THIS EVENING
THROUGH MUCH OF TONIGHT FOR NEARLY ALL OF THE TEXAS HILL COUNTRY
AND SOUTH CENTRAL TEXAS.  THE METROPOLITAN AREAS OF AUSTIN AND SAN
ANTONIO ARE INCLUDED IN THE SEVERE THUNDERSTORM POTENTIAL AREA.

AN UPPER-LEVEL STORM SYSTEM WILL COMBINE WITH A COLD FRONT TO
PRODUCE A LINE OF STRONG TO SEVERE THUNDERSTORMS THIS EVENING. THIS
SQUALL LINE WILL LIKELY FORM OVER THE HILL COUNTRY BY 10 PM AND
SPREAD EAST ACROSS MUCH OF SOUTH CENTRAL TEXAS DURING THE LATE
EVENING AND OVERNIGHT HOURS.

LARGE HAIL AND DAMAGING WINDS WILL BE THE MAIN SEVERE WEATHER
THREATS.  WITH NEARLY SATURATED SOILS ACROSS MOST AREAS...BRIEF FLASH
FLOODING IS ALSO POSSIBLE.  THESE THREATS WILL DIMINISH LATE TONIGHT
AS THE COLD FRONT PUSHES MORE STABLE AIR INTO THE REGION.

SPOTTER NETWORKS MAY NEED TO BE ACTIVATED TONIGHT ACROSS THE HILL
COUNTRY AND SOUTH CENTRAL TEXAS...ESPECIALLY IF A SEVERE WEATHER
WATCH OR WARNING IS ISSUED. STAY TUNED TO LOCAL TV...RADIO...CABLE
TV STATIONS...OR NOAA WEATHER RADIO FOR WEATHER BULLETINS.
