.DISCUSSION...

A PACIFIC STORM SYSTEM MOVING INTO THE WEST COAST TODAY...WILL
PUSH SOME MOISTURE NORTHWARD. HOWEVER...MOST OF THE SHOWER
ACTIVITY WILL REMAIN WEST OF THE DIVIDE...WITH ONLY A VERY SLIM
CHANCE OF GETTING ANY PRECIPITATION TODAY. AFTERNOON RELATIVE
HUMIDITY WILL BE HIGHER THAN WHAT OCCURRED OVER THE PAST WEEKEND.
THIS STORM SYSTEM WILL ALSO RESULT IN BREEZY WEST TO SOUTHWEST
WINDS DEVELOPING OVER THE FIRE SITE TODAY.

ISOLATED SHOWERS AND THUNDERSTORMS ARE POSSIBLE THROUGH THE WEEK
WITH THIS PACIFIC STORM SYSTEM...WITH MUCH COOLER AND A SLIGHTLY
BETTER CHANCE OF GETTING SOME PRECIPITATION THURSDAY NIGHT THROUGH
FRIDAY NIGHT AS THIS SYSTEM FINALLY PUSHES ACROSS THE COWBOY
STATE.

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