DISCUSSION
ISSUED AT 400 AM EDT SAT AUG 8 2026
CONSIDERABLY DRIER CONDITIONS HAVE FINALLY SPREAD ACROSS THE AREA.
THIS IS DUE TO DEEP LAYERED ATLANTIC RIDGING CENTERED OFF THE MID
ATLANTIC COAST EXPANDING WESTWARD INTO THE GULF. IN ADDITION,
WINDS HAD RELAXED TO A LIGHT TO GENTLE BREEZES THROUGH THE
EVENING. PRECIPITABLE WATER HAS ALSO FALLEN TO 2.08 INCHES. THIS
IS STILL ABOVE THE 75 PERCENTILE FOR THE DAY AND INHIBITION HAS
BEEN ABSENT. HOWEVER, CAPE WAS LIMITED BELOW 800 MB.
WITH THE DEPARTURE OF THE LOWER LEVEL TROUGH, EAST TO
SOUTHEASTERLY BREEZES HAVE INCREASED TO GENTLE TO MODERATE ACROSS
THE AREA AS THE SURFACE RIDGE EXERTS MORE CONTROL OVER OUR AREA.
THIS RIDGE WILL REMAIN PLANTED ACROSS FLORIDA AND THE GULF THROUGH
THE DURATION OF THE FORECAST. EXPECT BREEZES TO PEAK IN THE GENTLE
TO MODERATE RANGE OVERNIGHT AND LULL TO LIGHT TO GENTLE DURING THE
DAY. NO TREND IN TEMPERATURES ARE EXPECTED WITH HIGHS REMAINING
NEAR 90 AND LOWS IN THE LOWER TO MID 80S. DEW POINTS WILL HOVER IN
THE MID TO UPPER 70S.
IN GENERAL, THE DEEP LAYERED RIDGING WILL KEEP RAIN CHANCES SLIM
TO NONE THROUGH THE FORECAST, SCATTERED ACTIVITY CURRENTLY WORKING
ITS WAY ACROSS THE AREA SHOULD DIMINISH THROUGH THE MORNING HOURS.
IN ADDITION, A SUBTLE LOWER LEVEL TROUGH WILL MOVE ACROSS OUR
AREA SUNDAY INTO SUNDAY NIGHT AND MAY NUDGE POPS UP INTO LOW
CHANCE RANGE.
MARINE
ISSUED AT 400 AM EDT SAT AUG 8 2026
ATLANTIC RIDGING, STRETCHING ALONG THE GULF COAST WILL STRENGTHEN
OVER THE NEXT SEVERAL DAYS. AS A RESULT, MOSTLY GENTLE EAST TO
SOUTHEASTERLY BREEZES SHOULD BACK EASTERLY AND TREND UPWARDS.
WINDS WILL CONTINUE TO PEAK OVERNIGHT AND LULL DURING THE DAY.
PERIODIC CAUTIONS MAY BEGIN TO BE REQUIRED FOR PORTIONS OF KEYS
WATERS HEADING INTO MID WEEK. SHOWER AND THUNDERSTORM CHANCES WILL
BE NEAR TO SLIGHTLY BELOW NORMAL THROUGH THE DURATION.
