...JULY ENDS COOLER AND WETTER AFTER RECORD HEAT AND DROUGHT EARLY
IN THE MONTH AT SOUTH BEND...

DROUGHT CONDITIONS THAT PLAGUED THE SOUTH BEND AREA FROM LATE SPRING
THROUGH EARLY SUMMER CONTINUED TO INTENSIFY AND PERSIST THROUGH
EARLY JULY. THE DROUGHT MONITOR INDICATED D2 (SEVERE) DROUGHT
CONDITIONS ACROSS THE AREA THROUGH MOST OF THE MONTH...WITH D3
(EXTREME) DROUGHT CONDITIONS SOUTHEAST OF THE METRO AREA.

THE DROUGHT CONDITIONS WORSENED AS EXTREME HEAT PLAGUED THE REGION
FOR THE FIRST COUPLE WEEKS OF THE MONTH. TRIPLE DIGIT HEAT WAS
RECORDED FOR THREE CONSECUTIVE DAYS FROM THE 4TH THROUGH THE
6TH...WITH A HIGH OF 102 ON THE 6TH...THE WARMEST TEMPERATURE AT
SOUTH BEND SINCE JULY 30TH 1999. THIS STREAK OF THREE CONSECUTIVE
DAYS OF 100+ DEGREE TEMPERATURES IS THE THIRD LONGEST STREAK ON
RECORD AT SOUTH BEND.

THE HIGH TEMPERATURE REACHED 90 DEGREES 16 TIMES IN JULY...THE MOST
90+ DEGREE DAYS IN A MONTH SINCE JULY 1983. THE ALL TIME RECORD FOR
MOST 90+ DEGREE DAYS IN A MONTH IS 23...WHICH HAPPENED IN JULY 1901.
REMARKABLY...ONLY A TRACE OF PRECIPITATION FELL THROUGH THE 13TH OF
THE MONTH...WHICH COUPLED WITH THE EXTREME HEAT...PUT MAJOR STRESS
ON AREA CROPS AND LAWNS.

THE HIGH TEMPERATURE HIT 80 DEGREES EVERY DAY IN JULY. THIS IS ONLY
THE 3RD JULY ON RECORD WHEN THIS HAS OCCURRED...WITH 1955 AND 1921
BEING THE OTHER YEARS. JULY ENDS WITH A CURRENT 36 DAY STREAK OF 80+
DEGREE DAYS. THIS IS THE 5TH LONGEST SUCH STREAK...WITH THE LONGEST
SUCH STREAK AT 53 ENDING JULY 23RD 1921.

HOWEVER...A PATTERN CHANGE IN THE MIDDLE OF THE MONTH BROUGHT SOME
RELIEF TO THE AREA IN THE FORM OF PRECIPITATION AND COOLER
CONDITIONS. THE HIGH TEMPERATURE ONLY REACHED 90 DEGREES TWICE AFTER
THE 18TH OF THE MONTH...WHILE HITTING 90 DEGREES 14 OUT OF THE FIRST
18 DAYS OF THE MONTH. THE FOUR DAYS THAT DID NOT HIT 90 DURING THIS
STRETCH REACHED 89 DEGREES EACH DAY.

THE AVERAGE TEMPERATURE FOR THE MONTH WAS 79.5 DEGREES...WHICH IS
6.5 DEGREES ABOVE NORMAL. THIS IS THE SECOND WARMEST MONTH EVER AT
SOUTH BEND...ONLY BEHIND JULY 1921...WHEN THE AVERAGE TEMPERATURE
FOR THE MONTH WAS 80.0 DEGREES. THE HIGHEST TEMPERATURE FOR THE
MONTH WAS 102 ON THE 6TH...AND THE LOWEST TEMPERATURE FOR THE MONTH
WAS 58 ON THE 29TH.

THE AFOREMENTIONED PATTERN CHANGE BROUGHT A SERIES OF THUNDERSTORM
COMPLEXES THROUGH THE REGION OVER THE LAST COUPLE WEEKS OF THE
MONTH. EVEN THOUGH NO MEASURABLE PRECIPITATION FELL IN THE FIRST 13
DAYS OF THE MONTH...6.48 INCHES FELL FROM THE 14TH THROUGH THE END
OF THE MONTH...BRINGING RELIEF TO THE CROPS AND LAWNS THAT WERE
SPARED FROM EARLIER IN THE MONTH. INCREDIBLY...THIS MAKES JULY 2012
IS THE 8TH WETTEST JULY ON RECORD! THE 6.48 INCHES OF PRECIPITATION
FOR THE MONTH IS 2.48 INCHES ABOVE NORMAL. MEASURABLE PRECIPITATION
FELL ON ONLY 10 DAYS THIS MONTH...HOWEVER 4 OF THESE DAYS HAD OVER
0.50 INCHES OF PRECIPITATION...AND 2 OFF THESE DAYS HAD OVER 1.00
INCHES OF PRECIPITATION. A DAILY RAINFALL RECORD WAS BROKEN ON THE
19TH AS 2.06 INCHES FELL...BREAKING THE PREVIOUS DAILY RECORD OF
2.04 INCHES IN 1896.
