.AVIATION...

CIGS UNTIL 17Z. AN APPROACHING TROUGH WILL INCREASE WINDS AFTER

.PREV DISCUSSION... /ISSUED 635 PM CST FRI NOV 28 2014/

UPDATE...
TAKING A CLOSE LOOK AT THE HI-RES MODEL RUNS...IT LOOKS LIKE THERE
SHOULD BE A GOOD CHANCE FOR PATCHY FOG...OCCASIONALLY DENSE...AND FROM
DEL RIO TO SAT AND NORTH. THE MOISTURE DEPTH IS SHALLOW...BUT WITH
WITH FORECAST DEW POINT DEPRESSIONS AOA 1 DEGREE OR LESS OFF AND ON
THE ESCARPMENT...T OVERS OF AS LOW AS -6...AND A GOOD RADIATIONAL
SET UP INITIALLY WITH THE CLEAR SKIES AND LIGHT WINDS...THE
CONFIDENCE IN FOG OF SOME KIND IS PRETTY HIGH. THEREFORE EXPANDED
THE WX GRID TO INCLUDE ALL OF BEXAR COUNTY AND UP TO
FREDRICKSBURG FROM 10Z TO 13Z.
