.DISCUSSION...

A WAVE MOVING THROUGH EARLY THIS MORNING WILL START TO BREAK DOWN
THE RIDGE AND ALLOW SOME MORE MOISTURE INTO THE AREA. A FEW LIGHT
SHOWERS ARE EXPECTED EARLY WITH SOME CLEARING BY NOON AS A PUSH
OF DRIER AIR MOVES IN. THERE WILL STILL BE ENOUGH MID LEVEL MOISTURE
PRESENT TO ALLOW FOR THUNDERSTORMS TO DEVELOP AT PEAK HEATING
IN THE AFTERNOON. ANOTHER MORE ROBUST PUSH OF MOISTURE ARRIVES
ON WEDNESDAY AFTERNOON RESULTING IN MORE SHOWERS AND THUNDERSTORMS.
THE STORMS ON WEDNESDAY WILL HAVE A BETTER CHANCE OF WETTING
RAINS THAN THE STORMS TODAY...EXPECT A REPEAT ON THURSDAY AND
FRIDAY WITH DRIER SOUTHWEST FLOW POSSIBLY MOVING IN FOR THE WEEKEND.

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