What was reported inside it

Time	Report	Where	Remark
May 22, 3:40 PM EDT	TSTM WND GST 43	3 Se Jupiter, FL	OBSERVED AT MESONET SITE AT OAKES SUBSTATION IN JUPITER JUST WEST OF HIGHWAY 1 LESS THAN A MILE FROM COAST AT A HEIGHT OF 49 FEET ABOVE GROUND LEVEL.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Miami, FL (KMFL), launched 12:00Z, 7.6 hours before the alert went out and 119 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Miami, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at May 22, 2:20 PM EDT, 1 hour 13 minutes earlier.

Area forecast discussion, May 22, 2:20 PM EDT, 1 hour 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
220 PM EDT THU MAY 22 2008

DISCUSSION...THE AXIS OF A PERSISTENT STRONG MID ATMOSPHERIC RIDGE
AT H7 WILL REMAIN ACROSS CUBA AND THE SOUTHEAST BAHAMAS THROUGH
TONIGHT AND MOVE A LITTLE NORTH TO A KEYS LATITUDE ON FRIDAY BEFORE
WEAKENING ON SATURDAY. A MID-LEVEL ATMOSPHERIC DISTURBANCE IN THE
WESTERLIES WILL DIG THROUGH THE SOUTHEASTERN STATES FRIDAY AND
SATURDAY, RESULTING IN THE DEVELOPMENT OF A SURFACE LOW ON A WEAK
QUASI-STATIONARY FRONT ACROSS NORTH FLORIDA FRIDAY NIGHT WHICH WILL
MOVE EAST INTO THE ATLANTIC SATURDAY AND SATURDAY NIGHT. THIS WILL
PROVIDE ENOUGH PUSH TO GET A LATE SEASON COLD FRONT BARELY THROUGH
MAINLAND SOUTH FLORIDA SATURDAY NIGHT AND SUNDAY MORNING. EVEN
BETTER NEWS IS THAT CHANCES FOR SHOWERS AND THUNDERSTORMS WILL BE
NEAR OR EVEN ABOVE CLIMATOLOGY FOR THE NEXT FEW DAYS (CLIMATOLOGY
POPS FOR THE THIRD WEEK OF MAY ARE AROUND 30-40 PERCENT EACH DAY)
AND THE HEAT SHOULD BE LESS WITH THE INCREASED MOISTURE AND CLOUD
COVER.

STRONG THUNDERSTORMS WITH HEAVY RAINS ARE OVER THE LAKE OKEECHOBEE
MUCK FIRE AT THIS WRITING. WHILE IT MAY NOT BE ENOUGH TO PUT IT
COMPLETELY OUT, SINCE MUCK DOES SMOLDER UNDERGROUND, WILL NOT PLAN
A DENSE SMOKE ADVISORY FOR TONIGHT BUT WILL CHECK WITH AUTHORITIES
AFTER DARK TO SEE HOW MUCH RAINFALL WAS RECEIVED IN LAKEFRONT COMMUNITIES.

FOR THE EXTENDED PERIOD INCLUDING THE REST OF THE MEMORIAL DAY
HOLIDAY WEEKEND...SUNDAY WILL BE THE TRANSITION DAY WITH CONTINUING
ABOVE CLIMO CHANCES FOR SHOWERS AND THUNDERSTORMS MAINLY ALLIGATOR
ALLEY SOUTH, BUT DRYING OUT NORTH OF ALLIGATOR ALLEY. BACK TO A
SPRING AIR MASS WITH LOWER HUMIDITIES AND NORTHEASTERLY WINDS MONDAY
AND TUESDAY MODERATING WITH EASTERLY FLOW RETURNING LATE TUESDAY AND
WEDNESDAY. THE ATLANTIC WATER TEMPERATURE IS CLOSE TO 80, SO EXPECT
ONSHORE MOVING MARINE LAYER SHOWERS ANYTIME BEGINNING MEMORIAL DAY.

EVEN FARTHER OUT, THE GFS IS HINTING AT A MUCH WETTER PERIOD OF
SEVERAL DAYS BEGINNING THURSDAY BUT MUCH CAN HAPPEN BETWEEN NOW AND
THEN.

.AVIATION... A LIGHT SW FLOW PREVALING AT ALL TERMINALS TODAY.
SEABREEZE OVER THE EAST COAST TERMINALS EXPECTED TO CHANGE TO A SW
FLOW AFTER 00Z. VCSH ONLY EXPECTED TO CONTINUE UNTIL 00Z AT KPBI
DUE TO LAKE BREEZE. KAPF WILL EXPERIENCE VCSH UNTIL 23Z.

&&

RIVERA

.MARINE...EXCEPT FOR INCREASED SHOWERS AND THUNDERSTORMS, LIGHT
WINDS AND ONSHORE AFTERNOON SEA/LAKE BREEZES MEAN REASONABLY GOOD
BOATING WEATHER FRIDAY AND SATURDAY. AS THE COLD FRONT MOVES THROUGH
SATURDAY NIGHT AND SUNDAY, WITH A WIND SHIFT TO NORTH AND NORTHEAST
WINDS 15 TO 20 KNOTS AND GUSTY AT TIMES, SEAS WILL BE BUILDING AND
MARINE CONDITIONS WORSENING SUNDAY AND MEMORIAL DAY.

.FIRE WEATHER...INCREASING MOISTURE AND SHOWER/THUNDERSTORM CHANCES
MEANS A BIT OF RELIEF FROM FIRE WEATHER ISSUES THROUGH SATURDAY.
HOPEFULLY ENOUGH RAIN WILL FALL IN THE RIGHT PLACES TO DAMPEN
EXISTING FIRES NEAR LAKE OKEECHOBEE AND IN EVERGLADES NATIONAL PARK.
WORSENING FIRE WEATHER WITH LOWER HUMIDITIES AND HIGHER WINDS CAN BE
EXPECTED BEGINNING MEMORIAL DAY BUT TEMPERATURES SHOULD NOT BE
RECORD BREAKING AS THEY HAVE BEEN EARLIER THIS WEEK.

.CLIMATE...THE MEDIAN DATE OF THE BEGINNING OF SOUTH FLORIDAS
WETTER SEASON IS MAY 20, BUT WITH A COLD FRONT EXPECTED TO MOVE
THROUGH MAINLAND SOUTH FLORIDA THIS WEEKEND, THE ACTUAL BEGINNING
MAY BE DELAYED INTO THE LAST WEEK OF MAY. IF THE COLD FRONT IS NOT
AS STRONG OR MAKE IT AS FAR SOUTH AS EXPECTED, AN EARLIER START DATE
MAY BE DETERMINED IN HINDSIGHT. IT IS NOT UNUSUAL TO BE SEVERAL DAYS
PAST THE ACTUAL BEGINNING OF THE WETTER SEASON BEFORE WE SEE THAT IT
ACTUALLY DID BEGIN, POSSIBLY ON TIME.

.PRELIMINARY POINT TEMPS/POPS...
WEST PALM BEACH  75  88  74  90 / 20 40 30 60
