.DISCUSSION...A MODERATELY STRONG UPPER TROUGH WILL MOVE INTO THE
AREA TODAY WITH STRONG ONSHORE FLOW. THE HEAVY CLOUD COVER WILL
SLOWLY LIFT AND BREAK UP SOME THIS AFTERNOON. THERE IS AREAS OF
DRIZZLE WELL TO THE NORTH OF THE BURN AREA AND I CONTINUE TO EXPECT
THIS TO REMAIN TO THE NORTH. HOWEVER THERE IS A SMALL THREAT OF A
PASSING LIGHT SHOWER DURING THE AFTERNOON...MAINLY AFTER 2 PM. THERE
WILL BE A STEADY BREEZE OUT OF THE WEST TO SOUTHWEST THROUGH THE DAY
WITH THE STRENGTHENING ONSHORE FLOW.
