IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

...WIND INCREASING TODAY AND ESPECIALLY TOMORROW AS A LARGE UPPER-
LEVEL TROUGH APPROACHES FROM THE WEST...

.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.
