.DISCUSSION...

A DISTURBANCE MOVING ACROSS THE AREA WILL RESULT IN ISOLATED TO WIDELY
SCATTERED SHOWERS AND THUNDERSTORMS TODAY. EXPECT SLIGHTLY COOLER
TEMPERATURES AND HIGHER HUMIDITY AS WELL. GUSTY AND ERRATIC WINDS
FROM SHOWERS AND/OR THUNDERSTORMS WILL MAKE THE PREVAILING WIND
FORECAST A CHALLENGE. THUS...THERE IS LOW CONFIDENCE IN THE WIND
FORECAST. A WARM AND MAINLY DRY FORECAST WILL PREVAIL FOR THE REST
OF THE WEEK. VERY LOW RH IS ONCE AGAIN POSSIBLE LATER THIS
WEEK...BUT WINDS ARE EXPECTED TO REMAIN RELATIVELY LIGHT AND
TERRAIN DRIVEN.

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