AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SHREVEPORT LA
953 PM CST MON JAN 26 2015

.DISCUSSION...
THE 03Z SFC ANALYSIS INDICATES A WEAK SFC TROUGH EXTENDING FROM NW
TX INTO SRN OK AND WRN AR THIS EVENING...WHICH REMAINS PROGGED TO
SLOWLY SLIP SSE INTO EXTREME NE TX/SW AR LATE TONIGHT. THIS TROUGH
SHOULD BE NOTHING BUT A WIND SHIFT AS IT MIXES S ACROSS THE
REMAINDER OF E TX AND N LA TUESDAY MORNING...BEFORE SFC RIDGING
BUILDS S INTO THE REGION IN ITS WAKE. IR IMAGERY ALSO INDICATES A
RATHER EXTENSIVE CIRRUS SHIELD OVER MUCH OF CNTRL/SE TX THIS
EVENING...WITH SOME OF THE THIN CIRRUS ALREADY NUDGING INTO LOWER
E TX AS OF MID-EVENING. TEMPS SHOULD BE UNAFFECTED BY THE
CIRRUS...ALTHOUGH SFC OBS REVEAL THAT LIGHT WSW WINDS STILL RESIDE
S OF THE SFC TROUGH...WHICH HAS NOT ALLOWED TEMPS TO FALL AS
QUICKLY AS EARLIER EXPECTED.

FOR THE UPDATE...HAVE MADE ONLY MINOR TWEAKS TO FORECAST MIN
TEMPS BASED ON THE LATEST OBS...WHILE ALSO ADDING SOME SKY COVER
TO LOWER E TX TO REFLECT THE CIRRUS. OTHERWISE...THE CURRENT
FORECAST REMAINS IN GOOD SHAPE.

ZONE UPDATE ALREADY OUT...GRIDS WILL BE AVAILABLE SHORTLY.
