.DISCUSSION...

A BETTER SURGE OF MONSOONAL MOISTURE WILL OVERSPREAD THE REGION
TODAY. THIS WILL RESULT IN SCATTERED SHOWERS AND THUNDERSTORMS
THIS AFTERNOON WITH A GOOD CHANCE OF A WETTING RAIN DURING THE
AFTERNOON AND EVENING. THIS PRECIPITATION AND ASSOCIATED CLOUD
COVER WILL RESULT IN COOLER TEMPERATURES AND HIGHER RELATIVE
HUMIDITY THAN WHAT OCCURRED YESTERDAY. THE MINIMUM RELATIVE HUMIDITY
TODAY SHOULD OCCUR BETWEEN 10 AM AND 1 PM...BEFORE RISING DUE TO
INCREASING LOW LEVEL MOISTURE AND FALLING PRECIPITATION. ADDITIONAL
WET THUNDERSTORMS ARE POSSIBLE THURSDAY AND FRIDAY.

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