...BELOW AVERAGE PRECIPITATION IN JUNE LEADS TO SHORT TERM DROUGHT
AND FIRE DANGER CONCERNS...

THIS IS THE MONTHLY CLIMATE SUMMARY FOR JUNE 2012.

TEMPERATURE INFORMATION...
THOUGH THE MONTH OF JUNE ENDED ON A RATHER WARM NOTE...MONTHLY
AVERAGE TEMPERATURES WERE MUCH CLOSER TO NORMAL ACROSS THE AREA THAN
THEY HAD BEEN OVER THE PAST SEVERAL MONTHS. MONTHLY AVERAGE
TEMPERATURE DEPARTURES RANGED FROM 1.8 DEGREES ABOVE NORMAL AT
HATTIESBURG TO 1.1 DEGREES BELOW NORMAL AT GREENWOOD. JUNE BEGAN
WITH AVERAGE DAILY TEMPERATURES AS MUCH AS 10 DEGREES BELOW NORMAL
OVER THE FIRST TWO DAYS. TEMPERATURES THEN MODERATED TO NEAR NORMAL
OR SLIGHTLY ABOVE NORMAL READINGS THROUGH THE 22ND. THERE WERE A FEW
INSTANCES DURING THIS STRETCH IN WHICH DAYTIME PRECIPITATION AND
CLOUDINESS RESULTED IN WELL BELOW NORMAL DAILY TEMPERATURES. OVER
THE LAST WEEK OF THE MONTH TEMPERATURES WERE MUCH ABOVE NORMAL...
PARTICULARLY OVER THE SOUTHERN HALF OF THE AREA. OVER THE NORTHERN
HALF OF THE AREA...AN INFLUX OF DRIER AIR RESULTED IN ONLY SLIGHTLY
ABOVE NORMAL DAILY AVERAGE TEMPERATURES...BUT GREATER DAILY DIURNAL
TEMPERATURE RANGES. ON JUNE 27TH...THERE WAS A RANGE OF 42 DEGREES
BETWEEN THE HIGH AND LOW TEMPERATURES AT THE VICKSBURG TALLULAH
REGIONAL AIRPORT. THE HIGH OF 100 DEGREES MARKED A NEW RECORD
HIGH...AND THE LOW OF 58 DEGREES CAME ONLY TWO DEGREES SHY OF A
RECORD LOW! SIMILARLY A DIURNAL RANGE OF 43 DEGREES WAS OBSERVED AT
GREENWOOD ON THE SAME DAY.

OF NOTE...THE JUNE 2012 AVERAGE TEMPERATURE OF 77.6 DEGREES AT
GREENWOOD TIES AS THE 9TH COOLEST JUNE ON RECORD.

THE TEMPERATURE OUTLOOK FOR JULY FROM THE CLIMATE PREDICTION CENTER
INDICATES GREATER CHANCES FOR ABOVE-NORMAL TEMPERATURES THAN FOR
NEAR OR BELOW-NORMAL TEMPERATURES ALONG AND WEST OF THE NATCHEZ
TRACE PARKWAY. TO THE EAST...PREDICTABILITY IS LOW AND THERE ARE
EQUAL CHANCES FOR ABOVE...NEAR AND BELOW NORMAL TEMPERATURES. THE
OUTLOOK FOR JULY THROUGH SEPTEMBER INDICATES GREATER CHANCES FOR
ABOVE-NORMAL TEMPERATURES THAN FOR NEAR OR BELOW-NORMAL TEMPERATURES
FOR THE ENTIRE NWS JACKSON FORECAST AREA.


PRECIPITATION INFORMATION...
A SOMEWHAT NARROW CORRIDOR FROM NEAR GREENVILLE...ALONG HIGHWAY 49
TO JACKSON...THEN EASTWARD ALONG INTERSTATE 20...EXPERIENCED ABOVE
NORMAL PRECIPITATION IN JUNE. IN THESE AREAS MONTHLY PRECIPITATION
DEPARTURES RANGED FROM 0.77 INCHES ABOVE NORMAL AT GREENVILLE TO
1.22 INCHES ABOVE NORMAL AT JACKSON. HOWEVER ACROSS THE MAJORITY OF
THE AREA...JUNE PRECIPITATION WAS WELL BELOW NORMAL. HERE OBSERVED
PRECIPITATION DEPARTURES RANGED FROM 1.78 INCHES BELOW NORMAL AT
VICKSBURG/TALLULAH TO 2.46 INCHES BELOW NORMAL AT GREENWOOD. NWS
AHPS ANALYSIS INDICATES THAT MUCH OF THE GOLDEN TRIANGLE
AREA...SOUTH MISSISSIPPI...NORTHEAST LOUISIANA AND SOUTHEAST
ARKANSAS SAW MONTHLY PRECIPITATION DEPARTURES UPWARDS OF THREE TO
FIVE INCHES BELOW NORMAL. MANY OF THESE AREAS WERE ALREADY
ABNORMALLY DRY AT THE BEGINNING OF THE MONTH...AND THE CONTINUED
LACK OF RAINFALL HAS LEAD TO THE ONSET OF SHORT TERM DROUGHT
CONDITIONS AND INCREASED FIRE DANGER OVER MUCH OF THE REGION.

THE LATEST U.S. DROUGHT MONITOR NOW INDICATES THAT MODERATE TO
SEVERE DROUGHT CONDITIONS HAVE DEVELOPED ACROSS SOUTHEASTERN
ARKANSAS AND PORTIONS OF NORTHEASTERN LOUISIANA. MODERATE DROUGHT IS
ALSO INDICATED FOR SMALL PORTIONS OF NORTHERN BOLIVAR...NORTHERN
LEFLORE...AND NORTHERN SUNFLOWER COUNTIES IN MISSISSIPPI.
SURROUNDING THESE AREAS...ABNORMALLY DRY CONDITIONS ARE INDICATED
FOR THE REMAINDER OF SOUTHEASTERN ARKANSAS AND NORTHEASTERN
LOUISIANA. ABNORMALLY DRY CONDITIONS ARE ALSO DEPICTED FOR MUCH OF
SOUTHERN MISSISSIPPI...AREAS ALONG THE MISSISSIPPI RIVER IN
MISSISSIPPI...AND FOR THE HIGHWAY 82 CORRIDOR AND THE GOLDEN
TRIANGLE AREA. THE SEASONAL DROUGHT OUTLOOK NOW INDICATES THAT
DROUGHT COULD PERSIST OR INTENSIFY OVER PORTIONS OF NORTHEASTERN
LOUISIANA AND SOUTHEASTERN ARKANSAS.

THE PRECIPITATION OUTLOOK FOR JULY FROM THE CLIMATE PREDICTION
CENTER INDICATES LOW PREDICTABILITY ACROSS THE NWS JACKSON FORECAST
AREA. THUS THERE ARE EQUAL CHANCES FOR ABOVE...NEAR AND BELOW NORMAL
PRECIPITATION. THE OUTLOOK FOR JULY THROUGH SEPTEMBER INDICATES
GREATER CHANCES FOR ABOVE-NORMAL PRECIPITATION THAN FOR NEAR OR
BELOW-NORMAL PRECIPITATION OVER MUCH OF THE SOUTHERN HALF OF
MISSISSIPPI. ELSEWHERE...PREDICTABILITY IS LOW AND THERE ARE EQUAL
CHANCES FOR ABOVE...NEAR AND BELOW NORMAL PRECIPITATION.


SIGNIFICANT WEATHER EVENTS...
THERE WERE RELATIVELY FEW SIGNIFICANT WEATHER EVENTS IN THE MONTH OF
JUNE. ON THE 4TH...A CLUSTER OF STRONG TO SEVERE STORMS CAUSED WIND
DAMAGE FROM DERMOTT ARKANSAS...ALONG THE HIGHWAY 82 CORRIDOR
EASTWARD TO INDIANOLA. THE MOST NOTABLE EVENT TOOK PLACE ON JUNE
11TH...WHEN A LARGE COMPLEX OF SEVERE THUNDERSTORMS PUSHED FROM
NORTH TO SOUTH ACROSS THE NWS JACKSON FORECAST AREA DURING THE
EVENING HOURS. AS MANY AS 45000 WERE WITHOUT POWER DUE TO WIDESPREAD
TREE AND POWER LINE DAMAGE RESULTING FROM 60-70 MPH WINDS. AN 81 MPH
WIND GUST WAS RECORDED ON A PRIVATE WEATHER STATION IN ISOLA
MISSISSIPPI...AND SIGNIFICANT ROOF DAMAGE WAS REPORTED IN SUNFLOWER
COUNTY. IN ADDITION FLASH FLOODING WAS A SIGNIFICANT ISSUE IN THE
CITY OF JACKSON...AND IN PARTS OF WASHINGTON AND SUNFLOWER COUNTIES.
LATER ON THAT NIGHT...A SECOND LESS POTENT COMPLEX OF THUNDERSTORMS
DEVELOPED...CAUSING ADDITIONAL WIND DAMAGE OVER PORTIONS OF
NORTHEAST LOUISIANA AND THE MISSISSIPPI DELTA. ADDITIONAL FLOODING
WAS REPORTED NEAR DERMOTT AND CLEVELAND. FOR THE REMAINDER OF THE
MONTH...ONLY ISOLATED SEVERE STORMS WERE REPORTED ON THE 15TH AND
24TH.
