DISCUSSION
ISSUED AT 1116 PM EDT THU JUL 30 2026
ANOTHER AFTERNOON, ANOTHER LATE DAY CLOUD LINE. THIS ONE WAS WAY
LESS IMPRESSIVE THAN THE ONE THAT DEVELOPED YESTERDAY, THOUGH IT
DID MANAGE TO PRODUCE SOME SHOWERS BEFORE QUICKLY FIZZLING OUT.
SINCE THEN THE RADAR HAS BEEN VOID OF ANY PRECIPITATION ECHOS.
MEANWHILE, THE PRESSURE FIELD ACROSS THE KEYS CONTINUES TO BECOME
WEAKER AND MORE NEBULOUS. THIS IS RESULTING IN SLACKENING WINDS
WITH WINDS BECOMING LIGHT AND VARIABLE.
WINDS WILL REMAIN LIGHT AND CHAOTIC FRIDAY INTO THE FIRST HALF OF
THE WEEKEND. STARTING SUNDAY, A LARGE SURFACE LOW WILL SLOWLY
MEANDER EASTWARD FROM THE MISSISSIPPI VALLEY AND SETTLE ACROSS THE
EASTERN HALF OF THE U.S. THIS WILL TIGHTEN THE PRESSURE GRADIENT
AND LEAD TO AN INCREASE IN WINDS. IN ADDITION, MOISTURE WILL
GRADUALLY BEGIN INCREASING ACROSS THE REGION, SETTING UP FOR A
POTENTIALLY WET PATTERN EARLY NEXT WEEK.
MARINE
ISSUED AT 1116 PM EDT THU JUL 30 2026
WINDS HAVE GONE LIGHT AND VARIABLE THIS EVENING AND WILL CONTINUE
THROUGH THE OVERNIGHT AND INTO THE FIRST HALF OF THE WEEKEND. THE
EXCEPTION WILL BE THE WATERS IMMEDIATELY ADJACENT TO THE MAINLAND
WHICH WILL BRIEFLY FRESHEN TO LIGHT TO GENTLE IN THE AFTERNOON.
STARTING SUNDAY, A LARGE SURFACE LOW WILL MOVE INTO THE EASTERN
U.S. AND GRADUALLY TIGHTEN THE PRESSURE GRADIENT ACROSS THE
REGION. THIS WILL LEAD TO FRESHENING EAST TO SOUTHEAST BREEZES
INTO EARLY NEXT WEEK. IN ADDITION, THERE IS A POTENTIAL FOR A
RETURN TO A MORE ACTIVE WEATHER PATTERN.
