DISCUSSION
TODAY LOOKS LIKE A DRY AND WARM DAY. TEMPERATURES WILL BE SIMILAR
TO PAST FEW DAYS WITH HUMIDITY NEAR TO A FEW PERCENT LOWER THAN
YESTERDAY. WIND LOOKS TO BE LARGELY LIGHT AND TERRAIN DRIVEN BEFORE
INVERSIONS BREAK BETWEEN 1000 AND 1200, WITH A NORTHWEST BREEZE
DEVELOPING WITH GUSTS AS HIGH AS 20 MPH POSSIBLE AFTER 1400. A STRAY
SHOWER OR THUNDERSTORM CAN'T BE RULED OUT AFTER 1200 BUT THE CHANCE

EXCELLENT AFTER MORNING INVERSIONS BREAK. DRY WEATHER WILL CONTINUE
TOMORROW WITH SLIGHTLY WARMER TEMPERATURES AND LESS WIND. THE CHANCE
OF SHOWERS AND THUNDERSTORMS RETURNS ON WEDNESDAY AND CONTINUES
