.PREV DISCUSSION... /ISSUED 325 PM CST TUE MAR 3 2015/

DISCUSSION...
A WET PATTERN WILL SET UP OVER THE NEXT 24 TO 36 HOURS AS SOUTHWEST
FLOW ALOFT AND SOUTHERLY SURFACE WINDS BRING MOISTURE INTO THE REGION.
A WARM FRONT...CURRENTLY ALONG INTERSTATE 20...WILL MOVE NORTH
TONIGHT BRINGING WARMER TEMPS FOR THE REMAINDER OF THE CWA. THIS
WILL NOT LAST LONG AS A STRONG COLD FRONT WILL ENTER NORTHERN
AREAS EARLY WEDNESDAY MORNING. COMBINED WITH AN APPROACHING SHORT
WAVE...EXPECT SCATTERED TO NUMEROUS SHOWERS AND TSTMS TO RETURN
TO THE AREA TONIGHT CONTINUING INTO WEDNESDAY. FREEZING TEMPS WILL
REACH THE AREA EARLY WEDNESDAY EVENING...BUT THE SHALLOW WEDGE OF
COLD AIR WILL BE BLOCKED BY THE HIGHER ELEVATIONS TO THE NORTH OF
THE CWA. EXPECT THE COLD AIR TO WRAP AROUND INTO THE AREA FROM
BOTH THE WEST AND EAST OVERNIGHT...BUT THIS WILL TAKE SOME TIME.
THEREFORE THE WINTER STORM WATCH WHICH WAS PREVIOUSLY ISSUED WILL
BE DELAYED A FEW HOURS. IT WAS ALSO CANCELED FOR THE NORTHWEST
LOUISIANA PARISHES...AS THE FREEZING TEMPERATURES DO NOT REACH
THIS AREA UNTIL THE PRECIPITATION ENDS. THERE COULD BE BRIEF HOUR
OR TWO OF MIXED RAIN AND SLEET FOR THIS AREA...BUT NOT ENOUGH TO
WARRANT A WINTER STORM. THE REMAINING AREAS STILL IN THE WATCH
WILL NOW INCLUDE ALL OF THE TEXAS COUNTIES ALONG INTERSTATE 30 AND
CAN EXPECT BETWEEN ONE AND TWO TENTHS OF ICE AND OR SLEET ACCUMULATIONS.
ANY SNOW WILL BE LIMITED TO THE NORTHERN MOST COUNTIES WITH NO
MORE THAN ONE INCH FOLLOWING THE ICE AND SLEET. ACROSS SOUTHERN
ZONES...THE RAIN SHOULD END BEFORE THE FREEZING TEMPS ARRIVE.
WEATHER FROM THURSDAY THROUGH FRIDAY NIGHT WILL BE DRY WITH ANOTHER
ROUND OF BELOW NORMAL TEMPERATURES. A WARM UP WILL BEGIN SATURDAY
AND CONTINUE THROUGH TUESDAY ALONG WITH A SMALL CHANCE OF RAIN./14/.
