.DISCUSSION...

A STRONG RIDGE OF HIGH PRESSURE WILL RESULT IN DRY CONDITIONS AND
WELL ABOVE AVERAGE HIGH TEMPERATURES THURSDAY. HUMIDITY RECOVERY
IS EXPECTED TO BE EXCELLENT AT THE FIRE SITE...BUT WILL BE MUCH
LOWER IN THE POOR CATEGORY ON RIDGE TOPS DUE TO A STRONG SURFACE
INVERSION. AFTERNOON RH ON THURSDAY IS EXPECTED TO BE SLIGHTLY LOWER
THAN WHAT OCCURRED TODAY...BUT WINDS WILL BE A TAD LIGHTER...BUT
STILL GENERALLY NORTHWEST.

BREEZY NORTHWEST WINDS ARE EXPECTED FRIDAY AFTERNOON WITH RH
ABOUT 10 PERCENT HIGHER...THAN WHAT IS EXPECTED THURSDAY.

MODELS HAVE BEEN TRENDING FARTHER SOUTHWEST WITH THE NEXT STORM
NEXT SUNDAY AND MONDAY. THE BEST CHANCE FOR PRECIPITATION WILL BE
SUNDAY AFTERNOON AND NIGHT...BUT WIDESPREAD WETTING PRECIPITATION
IS BECOMING LESS LIKELY.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
...HAINES INDEX IS HIGH LEVEL HAINES BOTH DAY AND NIGHT...
