...CORRECTED FOR WIDELY SCATTERED THUNDERSTORMS AFTER 1500 HOURS...

...WIND INCREASING TODAY AND ESPECIALLY TOMORROW...

.DISCUSSION...TODAY WILL BE MUCH LIKE YESTERDAY BUT A LITTLE HOTTER
AND WITH MORE WIND. THERE SHOULD BE ENOUGH SOUTH TO SOUTHWEST FLOW
TO OVERCOME THE TERRAIN AND RESULT IN SOMETHING OTHER THAN LIGHT
NORTHWEST WIND. ALSO...I BELIEVE THE RELATIVE HUMIDITY MAY BE LOWER
THAN YOUR OBS INDICATE. THERE IS A SLIGHT CHANCE OF THUNDERSTORMS
THIS AFTERNOON AND EVENING IN THE HIGHER TERRAIN NEAR YOU. CHANCE OF
THE FIRE SITE BEING HIT IS LESS THAN 15 PERCENT. WINDS WILL BE MUCH
STRONGER SATURDAY WITH GUSTS TO 30 MPH ON EXPOSED RIDGES. RAIN EVENT
STILL HEADED IN WEDNESDAY.
