DISCUSSION
INCREASED MOISTURE AND OUR TYPICAL SUMMERTIME AIRMASS WILL KEEP
ISOLATED TO SCATTERED RAIN CHANCES IN THE FORECAST AT LEAST THE
WEEKEND. AS A RESULT, FIRE WEATHER CONCERNS ARE EXPECTED TO STAY
LIMITED AS MINIMUM RELATIVE HUMIDITY VALUES REMAIN ABOVE 50% FOR
THE FORESEEABLE FUTURE. LIGHT 20 FT WINDS WILL ALSO CONTINUE
THROUGH THE FIRE WEATHER PERIOD.
