POINTS DROP ANOTHER 15 DEGREES BEHIND THIS BOUNDARY. THE FRONT
WILL CONTINUE TO MAKE PROGRESS AND CROSS SE TX THIS MORNING.
TEMP FORECAST IS TRICKY AS TIMING DIFFERENCES COULD AFFECT MAX
TEMP FORECAST TODAY. THINK CLL WILL STAY ON THE COOL SIDE...AND

AGAIN OF SOME CONCERN. HAVE UPGRADED THE FIRE WEATHER WATCH TO A
WARNING OVER THE NORTH HALF AND WILL MAINTAIN THE WATCH OVER THE

OF SUB-FREEZING TEMPS WILL BE BRIEF AND A FREEZE WARNING WILL NOT
BE ISSUED. TEMPS WILL REMAIN UNSEASONABLY COOL ON SUNDAY WITH
LOWER HEIGHTS AND COOL 850 MB TEMPS. A WARM-UP WILL BEGIN ON MON
AND CONTINUE INTO WEDNESDAY. CLOUDS ON WEDNESDAY WILL KEEP TEMPS A
LITTLE COOLER. A PASSING S/WV ON WEDNESDAY WILL GIVE THE AREA A
