THRU TONIGHT...FOCUS FOR AFTN STORMS WILL CONTINUE TO BE OVER THE
NORTH INTERIOR SECTIONS WHERE HIGHER MOISTURE RESIDES (PWATS
CLOSE TO 2") AND SEA/LAKE BREEZE BOUNDARY COLLISIONS WILL OCCUR.
DRIER AIR MOVING IN FROM THE SOUTH AROUND THE RIDGE AXIS WILL KEEP
MOST DRY ALONG THE COAST SOUTH OF THE CAPE. CONVECTION WILL
LINGER A LITTLE PAST SUNSET ACROSS THE NORTH THEN ONCE THE
INSTABILITY IS WORKED OVER, A QUIET LATE EVENING/OVERNIGHT IS
FORECAST.
TUESDAY-SUNDAY...THE MID LEVEL RIDGE OF HIGH PRESSURE IS FORECAST
TO REMAIN ACROSS THE FL PENINSULA AND EVEN BUILD A LITTLE
STRONGER BY WED. THIS RIDGE WILL WEAKEN A BIT ON FRI ONLY TO BE
REPLACED BY A STRONGER MID LEVEL RIDGE CENTERED OVER THE CENTRAL
APPALACHIANS THIS WEEKEND. IN THE LOWER LEVELS, THE ATLC
SUBTROPICAL RIDGE AXIS WILL REMAIN DRAPED ACROSS NORTH/CENTRAL
FLORIDA. DRIER AIR WILL MOVE IN MID WEEK AND LOWER RAIN CHANCES TO
30% WED AND 30-40% WED AND THESE POPS MAY BE GENEROUS. THE LOWER
RAIN/STORM COVERAGE WILL PRODUCE ABOVE NORMAL MAX TEMPS IN THE MID
90S INTERIOR AND AROUND 90 COAST. THE DRIER AIR WILL HELP KEEP
DEWPOINTS IN CHECK SO HUMIDITY, WHILE PRESENT, WILL BE MODERATE.
THE COMBINATION OF HEAT AND HUMIDITY WILL PRODUCE PEAK HEAT
INDICES 100-105. WHILE THIS IS BELOW HEAT ADVISORY CRITERIA
(>=108), WIDESPREAD MODERATE HEATRISK IS FORECAST WITH MAJOR
HEATRISK ACROSS THE ORLANDO METRO AREA.
A BUMP IN RAIN CHANCES MAY COME FRIDAY WITH THE WEAKNESS IN THE
RIDGING ALOFT. THE FOCUS FOR STORMS WILL BE OVER THE NORTH
INTERIOR WITH 50-60% POPS DECREASING TO 30% ALONG THE TREASURE
COAST. THIS WEEKEND, THE LOW LEVEL HIGH PRESSURE RIDGE OVER THE
SW ATLC REBUILDS JUST TO OUR NORTH, NEAR 30N LAT, WHICH WILL
PRODUCE A PERSISTENT E/SE FLOW. HAVE KEPT POPS CLOSE TO CLIMO
(30-50%) THIS WEEKEND. THIS FLOW PATTERN FAVORS OVERNIGHT/MORNING
SHOWERS NEAR THE COAST SPREADING INLAND QUICKLY WITH A DIFFUSE
EAST COAST SEA BREEZE DURING THE DAY.
MARINE
ISSUED AT 252 PM EDT MON JUN 16 2025
THE ATLC SUBTROPICAL RIDGE AXIS WILL REMAIN ACROSS NORTH/CENTRAL
FLORIDA, LEADING TO GENERALLY FAVORABLE BOATING CONDITIONS.
