HEAVY RAINFALL ALONG WITH A ISOLATED SEVERE THUNDERSTORMS. SEVERE
STORMS DOWNED TREES ACROSS PORTIONS OF CHESTERFIELD COUNTY.

SOUTHWARD INTO SOUTH CAROLINA DURING THE LATE AFTERNOON AND EVENING
HOURS. AHEAD OF THE BOUNDARY THE AIRMASS BECAME STRONG UNSTABLE AND
CONDITIONS WERE CONDUCIVE FOR LARGE HAIL. THE WIND FIELD DURING THE
PERIOD WAS FAVORABLE FOR SPLITTING STORMS. NUMEROUS THUNDERSTORMS
DEVELOPED ACROSS THE NORTHERN HALF OF THE MIDLANDS AND INTO THE PEE
DEE REGION. SEVERAL OF THESE STORMS BECAME SEVERE AND PRODUCED LARGE
HAIL...UP TO BASEBALL SIZE AND STRONG DAMAGING WINDS. BASEBALL SIZE
HAIL WAS REPORTED ACROSS LANCASTER COUNTY AND NORTHERN RICHLAND
COUNTY. THE STRONG DAMAGING WINDS BROUGHT DOWN TREES AND POWERLINES
ACROSS RICHLAND...CLARENDON...LANCASTER AND FAIRFIELD COUNTIES. THE
LARGE HAIL BROKE CAR WINDOWS AND COVERED THE GROUND IN AREAS.

ON THE 25TH...THE SAME BACKDOOR COLD FRONT THAT PRODUCED ALL OF THE
SEVERE WEATHER ON THE 23RD HAD STALLED JUST SOUTH OF THE SAVANNAH
RIVER ON THE 25TH. A SQUALL LINE OF THUNDERSTORMS DEVELOPED ALONG
THIS BOUNDARY EVENTUALLY FORMING A BOW ECHO AND PRODUCING STRONG
DAMAGING WINDS AND LARGE HAIL. QUARTER TO HALF DOLLAR SIZE HAIL WAS
REPORTED IN BURKE COUNTY GA...COLUMBIA COUNTY GA...AIKEN COUNTY SC
AND EDGEFIELD COUNTY SC. THE STRONG WINDS BROUGHT DOWN LARGE
LIMBS...TREES AND POWERLINES IN LINCOLN COUNTY GA...BURKE COUNTY
GA...SALUDA COUNTY SC AND AIKEN COUNTY SC.

ON THE 26TH...THE FRONT REMAINED STALLED JUST SOUTH OF THE SAVANNAH
RIVER BUT WAS GRADUALLY WEAKENING. HOWEVER...DURING THE HEATING OF
THE DAY AN ISOLATED SEVERE THUNDERSTORM DEVELOPED AND PRODUCED
DOWNED TREES IN AIKEN COUNTY SC AND COLUMBIA COUNTY GA.

ON THE 27TH...THE SURFACE ANALYSIS SHOWS A WEAK SURFACE TROUGH OF
LOW PRESSURE STRETCHING FROM CENTRAL VIRGINA SOUTHWARD INTO CENTRAL
SOUTH CAROLINA. A FEW THUNDERSTORMS DEVELOPED DURING THE HEATING OF
THE DAY...HOWEVER ONE STORM BECAME SEVERE OVER THE CITY OF CAYCE.
THIS STORM PRODUCED A MICROBURST THAT DOWNED NUMEROUS TREES IN THE
CITY OF CAYCE AND ALONG THE CAYCE RIVERWALK ALONG THE CONGAREE
RIVER. ONE TREE FELL ON A HOME AND ANOTHER FELL ON A PICKUP TRUCK.
THE RIVERWALK HAD TO BE CLOSED TO CLEAN UP ALL OF THE TREES AND
DEBRIS FROM THE STORM.

ON THE 29TH...A FRONTAL BOUNDARY STALLED JUST SOUTH OF THE SAVANNAH
RIVER PRODUCED WIDELY SCATTERED THUNDERSTORMS ACROSS THE AREA. AN
ISOLATED SEVERE THUNDERSTORM DEVELOPED OVER CLARENDON COUNTY AND
DOWNED A FEW TREES AND POWERLINES.

ON THE 31ST...WIDELY SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPED
LATE ON THE 30TH AND INTO THE EARLY MORNING HOURS OF THE 31ST. A
CLUSTER OF STORMS MOVED OVER DOWNTOWN COLUMBIA AND PRODUCED 1 TO 2
INCHES OF RAIN IN JUST OVER 1 HOUR. THE LOCALLY HEAVY RAIN PRODUCED
MINOR FLOODING ALONG ROCKY BRANCH CREEK. THE STREAM GAGE AT PICKENS
STREET CRESTED AT 8.0 FEET...FLOOD STAGE IS 7.2 FEET. THE STREAM
GAGE AT WHALEY STREET AND MAIN STREET CRESTED AT 7.8 FEET...FLOOD
STAGE IS 7.2 FEET.

DURING THE AFTERNOON OF THE 31ST...SHOWERS AND THUNDERSTORMS
PRODUCED LOCALLY HEAVY RAIN ACROSS PORTIONS OF THE CENTRAL SAVANNAH

COVERED BY UP TO ONE FOOT OF WATER IN PLACES. RADAR RAINFALL

THE OUTLOOK FOR JUNE...

THE FORECAST CALLS FOR EQUAL CHANCES THAT TEMPERATURES WILL EITHER
BE BELOW...ABOVE OR NEAR NORMAL. THERE IS A 33 TO 40 PERCENT CHANCE
THAT RAINFALL WILL BE ABOVE NORMAL.

THE 3-MONTH OUTLOOK FOR THE SPRING (JUN/JUL/AUG)...

THE FORECAST CALLS FOR A 33 TO 40 PERCENT CHANCE OF ABOVE NORMAL
TEMPERATURE...AND EQUAL CHANCES THAT PRECIPITATION WILL EITHER BE
BELOW...ABOVE OR NEAR NORMAL FOR THE 3-MONTH PERIOD.

ENSO (EL NINO SOUTHERN OSCILLATION)...
...A EL NINO WATCH HAS BEEN ISSUED FOR THE LATE SUMMER OR EARLY
FALL...
AN EL NINO WATCH MEANS THAT CONDITIONS ARE FAVORABLE FOR THE
DEVELOPMENT OF EL NINO CONDITIONS WITHIN THE NEXT SIX MONTHS.

AT THIS TIME...ENSO NEUTRAL CONDITIONS CONTINUE ACROSS THE
EQUATORIAL PACIFIC OCEAN. SEA SURFACE TEMPERATURES ARE ABOVE AVERAGE
ACROSS THE EQUATORIAL PACIFIC OCEAN. TROPICAL RAINFALL IS NEAR
AVERAGE ACROSS INDONESIA AND THE TROPICAL PACIFIC. THE CHANCES OF
EL NINO INCREASE DURING THE REMAINDER OF THE YEAR...EXCEEDING 65
PERCENT BY SUMMER AND PEAKING NEAR 80 PERCENT DURING THE LATE FALL
INTO EARLY WINTER.
