.DISCUSSION...

HOT...DRY...WINDY AND UNSTABLE TODAY WITH A DRY COLD FRONTAL PASSAGE
EXPECTED AT AROUND 9PM THIS EVENING. SURROUNDING AREAS ARE UNDER
RED FLAG WARNINGS FOR THE AFTERNOON...THE ZONE SURROUNDING THE FIRE
WOULD BE TOO IF FUELS WERE CONSIDERED TO BE CRITICAL.

A SECOND...MORE SIGNIFICANT COLD FRONT WILL PASS ON FRIDAY. A FEW
SHOWERS AND THUNDERSTORMS MAY RESULT AS MID LEVEL MOISTURE INCREASES.
SURFACE MIN RHS WILL STILL BE IN THE UPPER TEENS HOWEVER...INCREASING
THE CHANCE OF STRONG AND GUSTY WINDS ASSOCIATED WITH THE STORMS.
HIGH TEMPERATURES WILL BE ABOUT 5 DEGREES COOLER BUT WINDS WILL
REMAIN MODERATE WITH A HIGH PROBABILITY OF GUSTS IN EXCESS OF 25 MPH.

A RIDGE TRIES TO BUILD BACK IN ON SATURDAY ONLY TO BE FLATTENED
BY A PASSING SHORT WAVE ON SUNDAY...WHICH SHOULD BRING THUNDERSTORMS
BACK TO THE AREA.

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