.DISCUSSION...
A COLD FRONT WAS MOVING THROUGH THE AREA EARLY THIS MORNING BUT
IS NOT EXPECTED TO HAVE A GREAT DEAL OF AFFECT ON THE FIRE SITE.
GUSTY RIDGETOP WINDS FROM THE NORTH/NORTHWEST ARE POSSIBLE DUE TO
THE FRONT THROUGH ABOUT 10 AM. OTHERWISE...NORTHEAST WINDS AT
SUNRISE WILL TURN WESTERLY BY MIDDAY. TEMPERATURES WILL BE A
LITTLE COOLER THAN YESTERDAY BEHIND THE FRONT. THERE IS A SLIGHT
CHANCE OF AN AFTERNOON SHOWER WITH SOME THUNDER...BUT I BELIEVE
THE BEST CHANCE OF ANY SHOWERS WILL REMAIN SOUTH AND WEST OF THE
FIRE SITE. THERE IS JUST A LITTLE BIT BETTER CHANCE OF A SHOWER
TUESDAY AFTERNOON.
