CURRENTLY: CONVECTION BEGINNING TO POP ALONG A COUPLE OF BOUNDARIES

LEFT OVER FROM MORNING ACTIVITY EXTENDS FROM NORTHERN POLK COUNTY
SOUTHWESTWARD TO SOUTHEASTERN HILLSBOROUGH COUNTY. THIS BOUNDARY
SHOULD CONTINUE TO MOVE NORTHEASTWARD IN LIGHT SOUTHWESTERLY FLOW.

GULF SEA BREEZE BOUNDARIES ARE STARTING TO MAKE THEIR PRESENCE
KNOWN...BUT ARE STARTING OUT QUITE A BIT LATER THAN YESTERDAY WITH
ONLY A BIT OF INWARD PENETRATION SO FAR. THE BOUNDARY SHOULD
CONTINUE TO MOVE SLOWLY NORTHEASTWARD THROUGH THE AFTERNOON...
EVENTUALLY MEETING THE EAST COAST SEA BREEZE BOUNDARY IN THE
INTERIOR COUNTIES LATER THIS AFTERNOON.

FORECAST: WE WILL GRADUALLY BE SHIFTING TO A MORE CLIMATOLOGICAL
DEEP SOUTHEASTERLY FLOW BY THE FIRST HALF OF THE WORK WEEK...WITH
ALL MODELS FAIRLY CONSISTENT ON THE SHIFT. SUNDAY WE WILL SEE
SOUTHEASTERLY FLOW DEEPEN TO ABOUT 600 MB IN THE SOUTH AND 750 MB
IN THE CENTRAL...WITH GENERALLY A SOUTHERLY FLOW OVER THE NORTH.
AFTERNOON SEA BREEZE CIRCULATIONS WILL AGAIN RULE...ALTHOUGH THE
SEABREEZE MAY BE LATE IN MOVING INLAND OVER THE SOUTH. THIS WILL
GIVE MORE A THREAT OF THUNDERSTORMS FOR THE COASTAL AREAS AROUND
PUNTA GORDA AND FORT MYERS.

SOUTHEASTERLY FLOW. AT 48 HRS...NGM WORKS IN A BAND OF DRY AIR FROM
