BOUNDARY COLLISIONS PRODUCED A FEW STRONG STORMS OVER
THE ORLANDO METRO THIS EVENING...WITH THE LAST FEW COLLISIONS
CURRENTLY PLAYING OUT ACROSS MARION..LAKE AND PUTNAM COUNTIES. A FEW
OF THE STORMS FURTHER NORTH WILL DRIFT INTO LAKE COUNTY THROUGH LATE
EVENING AND ALSO BRUSH THE FOUR CORNERS REGION NEAR THE ATTRACTIONS
AREA. SOME WEAK MID LEVEL SHORTWAVE ENERGY WILL HELP ACTIVITY LINGER
IN THESE AREAS THROUGH MIDNIGHT...BUT FOR THE MOST PART ACTIVITY IS
ON THE WANE.

CONDITIONS DO NOT LOOK AS FAVORABLE FOR FOG AND STRATUS TONIGHT AS
THERE WILL BE AN INCREASE IN HIGH CLOUDS FROM THE WEST AND A
PERSISTENT...ALBEIT LIGHT...ONSHORE FLOW NEAR THE COAST. BEST CHANCE
FOR ANY PATCHY FOG WILL BE OVER THE FAR INTERIOR WHERE WINDS SHOULD
GO CALM.

FRONTAL BOUNDARY/MOISTURE BAND THAT PASSED US YESTERDAY AND IS
CURRENTLY OVER S FLORIDA WILL BEGIN TO SHIFT BACK NORTHWARDS
OVERNIGHT. THERE WILL BE A SLOW INCREASE IN SHOWERS OVER THE
ATLANTIC...WITH A FEW APPROACHING/BRUSHING THE COAST TOWARD MORNING
AS ONSHORE (E/NE) FLOW BEGINS TO INCREASE. GIVEN THE PROXIMITY OF
THE BOUNDARY TO THE TREASURE COAST BY DAYBREAK...HAVE ADDED IN THE
MENTION OF ISOLATED SHOWERS THERE LATE TONIGHT.
