WINTER WX ADVISORY CRITERIA...MAINLY ACROSS MTNS. ALTHOUGH WINDY
CONDITIONS ARE EXPECTED ALONG WITH COOLER TEMPS BEHIND FRONT. WIND
CHILLS ALBEIT VERY COLD SHOULD REMAIN ABOVE VALUES NEEDED FOR

DEVELOP ON THU ACROSS THE WRN GULF OF MEX. HERE IS WHERE THE

TROUBLE PROCESSING THE GULF LOW AND HOW FAR N THIS SYSTEM WILL BE
AS IT MOVES EWD...WHICH WILL MAKE A BIG...BIG DIFFERENCE FOR
FRIDAY/S FORECAST. WILL HAVE THE COLD AIR IN PLACE. HAVE LOW
CONFIDENCE POPS IN FOR FRI WITH UNCERTAINTY ON THIS SYSTEM. IF LOW
