THIS MORNING SFC OBS AND AREA DOPPLER RADARS WERE INDICATING SNOW
OCCURRING FROM DRYDEN...SONORA AND BROWNWOOD WESTWARD TO FAR WEST
TEXAS. THIS PCPN WAS MOVING EASTWARD AND WILL BE MOVING INTO THE
THE HILL COUNTRY AND EDWARDS PLATEAU THIS MORNING. SHOWERS WERE
ALSO FORMING ACROSS DEEP SOUTH TEXAS FROM LAREDO TO ALICE. THIS
ACTIVITY WAS THE RESULT OF AN APPROACHING UPPER LEVEL TROF. THIS
TROF WILL MOVE RAPIDLY ACROSS TEXAS TODAY. THERE WILL BE NO
CHANGES TO THE WINTER WEATHER ADVISORY. LOOKS LIKE OUR CWFA WILL
HAVE TWO WEST TO EAST SNOW STREAKS TODAY. ONE WILL BE ACROSS THE
EASTERN HILL COUNTRY WHERE ONE TO TWO INCHES OF SNOW IS POSSIBLE.
THE OTHER SNOW STREAK WILL BE ACROSS OUR SOUTHEAST COUNTIES WHERE
BETTER MOISTURE WILL AVAILABLE IN THE LOWER LEVELS THANKS TO THE
CLOSE PROXIMITY OF THE GULF OF MEXICO. THE PCPN WILL BE EAST OF
OUR CWFA BY 6 PM THIS EVENING. PLEASE REFER TO OUR WINTER WEATHER
ADVISORY FOR MORE DETAILS.
A COLD AND DRY AIRMASS WILL CONTINUE TO OVERSPREAD SOUTH CENTRAL
TEXAS TONIGHT IN THE WAKE OF THE UPPER LEVEL TROF. CLEAR SKIES AND
LOW DEWPOINTS WILL LEAD TO A HARD FREEZE ACROSS ALL OF OUR CWFA.
A FREEZE WARNING WILL BE ISSUED FOR ALL OF OUR CWFA...INCLUDING THE
HILL COUNTRY AND EDWARDS PLATEAU. EVEN THOUGH THESE REGIONS HAVE
ALREADY EXPERIENCED A FREEZE...LOW TEMPS IN THE UPPER TEENS TO
LOWER 20S WARRANTS A RE-ISSUANCE OF THE FREEZE WARNING FOR THE
HILL COUNTRY AND EDWARDS PLATEAU. BELOW NORMAL TEMPERATURES WILL
CONTINUE OVER THE WEEKEND AS THE POLAR AIRMASS IS SLOW TO MODIFY.
ANOTHER COLD FRONT WILL PUSH SOUTHWARD ACROSS SOUTH CENTRAL TEXAS
TUESDAY NIGHT. PCPN ASSOCIATED WITH THIS SYSTEM TUESDAY AND TUESDAY
NIGHT WILL REMAIN LIQUID. THIS FRONT WILL ALSO KEEP AFTERNOON
TEMPS BELOW NORMAL WEDNESDAY AND THURSDAY WITH ANOTHER FREEZE
LIKELY THURSDAY MORNING FOR THE HILL COUNTRY AND EDWARDS PLATEAU.
NEAR NORMAL AFTERNOON TEMPS ARE FINALLY IN THE OFFING FOR FRIDAY.
LOOKS LIKE THE COOL AND WET WEATHER PATTERN FOR THIS WINTER DUE TO
EL NINO IS ON TRACK.
