.DISCUSSION...
AN UPPER HIGH CONTINUES TO SWING MONSOONAL MOISTURE INTO THE AREA.
THE LOCATION OF THE FIRE ALONG THE PERIPHERY OF THE HIGH MAKES IT
SUSCEPTIBLE TO PASSING SHORT WAVES THAT LIKE TO RIPPLE ALONG ITS
OUTER EDGE...LEAVING THE AREA VULNERABLE TO THUNDERSTORM ACTIVITY.
THERE WILL BE PLENTY OF MOISTURE FOR THUNDERSTORMS TO WORK WITH AS
SURFACE HEATING DESTABILIZES THE ATMOSPHERE THIS AFTERNOON. A
SHORT WAVE WILL PASS TO THE NORTH THIS AFTERNOON...PROVIDING FURTHER
SUPPORT FOR THE STORMS AND POSSIBLY KEEP THEM GOING INTO THE NIGHT
AGAIN. A STRONGER WAVE WILL MOVE THROUGH ON SATURDAY EVENING...ONCE
AGAIN PROVIDING SUPPORT FOR THUNDERSTORMS. THIS PATTERN WILL PERSIST
THROUGH THE WEEKEND.

FLOW WILL REMAIN GENERALLY LIGHT AND FROM THE SOUTHWEST...TAKING ON
A NORTHERLY COMPONENT AS THE WAVES PASS. WINDS WILL BE GUSTY AND
ERRATIC AROUND THUNDERSTORMS...MAKING THE DIRECTION HARD TO PREDICT
VERY FAR IN ADVANCE.

TEMPERATURES WILL BE ON A GRADUALLY DECREASING TREND AS PRESSURE
LOWERS SLOWLY THROUGH EARLY NEXT WEEK. RH WILL BE NEARLY STEADY
WITH A SLIGHT UPWARD TREND.

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