Summer of extremes - 2007

 

...A SUMMER OF TWO EXTREMES...DROUGHT FOLLOWED BY FLOOD...

THE SUMMER MONTHS OF JUNE...JULY AND AUGUST 2007 WILL GO DOWN AS A PERIOD OF VERY DRY CONDITIONS AND RAINFALL DEFICITS THAT QUICKLY TRANSITIONED TO PERIODS OF HEAVY RAIN...FLOODING AND RAINFALL SURPLUSES ACROSS MUCH OF NORTHERN INDIANA...SOUTHWEST LOWER MICHIGAN...AND NORTHWEST OHIO. MUCH OF NORTHWEST OHIO...NORTHEAST INDIANA AND SOUTHWEST LOWER MICHIGAN BEGAN AUGUST IN MODERATE (D1) AND SEVERE (D2) DROUGHT. BY THE END OF AUGUST...THE ENTIRE REGION OF NORTHERN INDIANA...NORTHWEST OHIO...AND SOUTHWEST LOWER MICHIGAN WERE COMPLETELY OUT OF DROUGHT AND DRY CONDITIONS. LOCATIONS THAT BEGAN THE MONTH WITH YEARLY PRECIPITATION TOTALS FROM 3 TO 6 INCHES BELOW NORMAL...FINISHED THE MONTH WITH YEARLY SURPLUSES NEAR OR ABOVE NORMAL. THIS WAS AN INCREDIBLE TURN AROUND FUELED BY AN ACTIVE STATIONARY BOUNDARY AND REMNANTS OF TROPICAL STORM ERIN WHICH INTERACTED WITH THIS BOUNDARY.

AT SOUTH BEND...THE SUMMER OF 2007 WAS THE 4TH WETTEST ON RECORD WITH 16.08 INCHES OF RAIN. THIS WAS 4.18 INCHES ABOVE NORMAL. THIS IS EVEN MORE REMARKABLE WHEN YOU CONSIDER THAT JUNE ONLY HAD 1.80 INCHES...2.39 INCHES BELOW NORMAL. FOR THE JANUARY THROUGH AUGUST PERIOD...SOUTH BEND NOW STANDS WITH 29.58 INCHES...3.42 INCHES ABOVE NORMAL.

AT FORT WAYNE...THE SUMMER OF 2007 DID NOT BREAK THE TOP TEN IN TERMS OF PRECIPITATION RECORDS. FORT WAYNE DID RECEIVE 14.55 INCHES OF RAIN FOR THE SUMMER...3.33 INCHES ABOVE NORMAL. A DRY JUNE AND JULY OFFSET THE 2ND WETTEST AUGUST EVER.   FOR THE JANUARY THROUGH AUGUST
PERIOD...FORT WAYNE NOW STANDS WITH 27.21 INCHES...1.85 INCHES ABOVE NORMAL.

BELOW IS A MONTH BY MONTH ACCOUNT OF HOW THIS SUMMER PROGRESSED. FOR DETAILED CLIMATE DATA FOR OTHER LOCATIONS AROUND NORTHERN INDIANA...SOUTHWEST LOWER MICHIGAN AND NORTHWEST OHIO...VISIT WWW.WEATHER.GOV/IWX .

JUNE 2007

JUNE WAS WARM AND VERY DRY. SCATTERED THUNDERSTORMS WITH LOCALLY HEAVY RAIN BROUGHT SOME RELIEF TO AREAS LATE IN THE MONTH...BUT MANY LOCATIONS EXPERIENCED ABNORMALLY DRY CONDITIONS. RAINFALL DEFICITS GENERALLY RANGED FROM 1.0 TO 3.0 INCHES BELOW NORMAL. SOUTH BEND EXPERIENCED A RAINFALL DEFICIT OF 2.39 INCHES...WHICH MADE IT THE 11TH DRIEST JUNE ON RECORD. FORT
WAYNE EXPERIENCED A RAINFALL DEFICIT OF 1.00 INCH.  ONE OF THE DRIEST AREAS WAS NORTHWEST OHIO. LIMA OHIO RECORDED A JUNE RAINFALL DEFICIT OF 2.03 INCHES. VAN WERT COUNTY EMERGENCY MANAGER
RICK MCCOY REPORTED LESS THAN 2 INCHES OF RAIN IN VAN WERT SINCE MID APRIL. HE ALSO REPORTED LARGE ACREAGE OF BEANS HAD STARTED TO SPROUT DURING JUNE BUT DIED DUE TO THE LACK OF RAIN. 
CORN WAS REPORTED TO BE BETWEEN 1 AND 2 FEET TALL WITH SEVERE CURLING. PARTS OF NORTHERN INDIANA AND SOUTHWEST LOWER MICHIGAN WERE ALSO EXPERIENCING SEVERE CURLING DUE
TO THE LACK OF RAINFALL.

IT WAS A RATHER WARM JUNE WITH SEVERAL DAYS EXPERIENCING HIGH TEMPERATURES OF 90 DEGREES OR WARMER. SOUTH BEND RECORDED 7 DAYS OF 90 OR WARMER...FORT WAYNE...GOSHEN AND LIMA 8 DAYS...AND DEFIANCE 6 DAYS. IT WAS THE 12TH WARMEST JUNE ON RECORD AT SOUTH BEND AND THE
16TH WARMEST JUNE AT FORT WAYNE.

JULY 2007

DRY CONDITIONS CONTINUED INTO JULY AS SEVERE DROUGHT CONDITIONS DEVELOPED OVER PARTS OF NORTHERN INDIANA...SOUTHWEST LOWER MICHIGAN AND NORTHWEST OHIO. NORTHWEST INDIANA AND SOUTHWEST LOWER MICHIGAN BEGAN TO EXPERIENCE MORE RAINFALL DURING THE LATTER HALF OF THE MONTH...WHICH PUSHED MONTHLY RAINFALL TOTALS ABOVE NORMAL. SOUTH BEND RECEIVED 5.40 INCHES OF RAIN...1.67 INCHES ABOVE NORMAL...AND BENTON HARBOR RECEIVED 3.76 INCHES...0.52 INCHES ABOVE NORMAL. HOWEVER...TO THE EAST OF THESE AREAS...PRECIPITATION TOTALS DROPPED OFF SIGNIFICANTLY AS DRY CONDITIONS CONTINUED WITH ONLY ISOLATED THUNDERSTORMS AND HEAVY RAINFALL. FORT WAYNE RAINFALL FOR JULY WAS ONLY 1.82 INCHES...1.76 INCHES BELOW NORMAL...DEFIANCE OHIO RECEIVED 2.80 INCHES...1.09 INCHES BELOW NORMAL...AND LIMA OHIO RECEIVED 1.47 INCHES...2.79 INCHES BELOW NORMAL.

SOUTH BEND...FORT WAYNE AND GOSHEN INDIANA ALL HAD 5 DAYS OF 90 DEGREES OR HIGHER...LIMA AND DEFIANCE OHIO BOTH HAD 4 DAYS AND BENTON HARBOR MICHIGAN EXPERIENCED 3 DAYS OF 90 DEGREES OR HIGHER.

 AUGUST 2007

THE BEGINNING OF AUGUST WAS A TRANSITION FROM VERY DRY TO VERY WET CONDITIONS. WHILE NORTHWEST AREAS WERE FINALLY SEEING MUCH NEEDED RAINFALL...EASTERN AREAS WERE STILL EXPERIENCING SEVERE DROUGHT CONDITIONS AT THE BEGINNING OF THE MONTH. THIS FINALLY BEGAN TO CHANGE IN THE SECOND AND THIRD WEEKS AS A QUASI-STATIONARY FRONT MEANDERED ACROSS THE AREA. AS THIS OCCURRED...REMNANTS FROM TROPICAL STORM ERIN ALSO DRIFTED NORTH INTO THE MISSISSIPPI RIVER VALLEY AND BROUGHT COPIOUS AMOUNTS OF MOISTURE WITH IT. THE INTERACTION OF THIS TROPICAL SYSTEM WITH THE STATIONARY FRONT CREATED NUMEROUS ROUNDS OF THUNDERSTORMS WITH VERY HEAVY RAINFALL DURING THE MIDDLE OF AUGUST. HEAVY RAIN AND FLOODING STRETCHED FROM EASTERN IOWA...SOUTHERN MINNESOTA...SOUTHERN WISCONSIN AND NORTHERN ILLINOIS EAST THROUGH NORTHERN INDIANA...SOUTHERN MICHIGAN AND NORTHWEST OHIO. THIS HEAVY RAIN CONTINUED INTO THE FOURTH WEEK OF AUGUST BEFORE THE PESKY STATIONARY FRONT FINALLY MOVED OUT OF THE AREA.

BY THE TIME AUGUST WAS OVER...MANY AREAS HAD RECEIVED RECORD OR NEAR RECORD RAINFALL FOR THE MONTH. SOUTH BEND BROKE THE RECORD FOR THE WETTEST AUGUST WITH 8.88 INCHES...4.90 INCHES ABOVE NORMAL! THIS WAS ALSO THE 7TH WETTEST MONTH EVER AT SOUTH BEND. BENTON HARBOR MICHIGAN RECEIVED MORE RAINFALL WITH 12.20 INCHES...8.73 INCHES ABOVE NORMAL. THIS WAS ALSO A RECORD FOR AUGUST. FORT WAYNE RECORDED 9.69 INCHES...6.09 INCHES ABOVE NORMAL. THIS WAS THE SECOND WETTEST AUGUST ON RECORD AT FORT WAYNE AND THE 5TH WETTEST MONTH EVER. GOSHEN INDIANA RECEIVED A RECORD 10.06 INCHES OF RAIN...6.09 INCHES ABOVE NORMAL.

THE HEAVY AND PERSISTENT RAINFALL LED TO FLOODING ACROSS MANY AREAS. THE MOST SEVERE FLOODING TOOK PLACE IN NORTHWEST OHIO WHERE 10 TO 15 INCHES OF RAIN FELL DURING AUGUST. DEFIANCE REPORTED 11.10 INCHES OF RAIN...7.89 INCHES ABOVE NORMAL AND LIMA REPORTED 9.91 INCHES...6.53 INCHES ABOVE NORMAL. BETWEEN 5 AND 8 INCHES OF RAIN FELL BETWEEN AUGUST 20TH AND AUGUST 23RD IN NORTHWEST OHIO. THIS LED TO RAPID RISES IN LOCAL STREAMS AND RIVERS...WITH THE MOST SEVERE FLOODING OCCURING ALONG THE BLANCHARD RIVER. AT OTTAWA OHIO...THE BLANCHARD RIVER REACHED ITS SECOND HIGHEST CREST EVER...TOPPING OUT AT 31.70 FEET ON AUGUST 23RD. THE ENTIRE TOWN OF OTTAWA EXPERIENCED DEVESTATING FLOODING. MINOR TO MODERATE RIVER FLOODING ALSO OCCURRED ALONG THE AUGLAIZE...MAUMEE AND TIFFIN RIVERS IN NORTHWEST OHIO.   

AUGUST ALSO SAW ITS SHARE OF SEVERE WEATHER. DURING THE LATE EVENING OF AUGUST 15TH AND EARLY MORNING HOURS OF AUGUST 16TH...A LINE OF SEVERE THUNDERSTORMS DEVELOPED AND MOVED SOUTHEAST ACROSS INDIANA AND INTO NORTHWEST OHIO. THIS LINE PRODUCED WIDESPREAD WIND DAMAGE AND LARGE HAIL. IN ADDITION...TWO TORNADOES WERE CONFIRMED NEAR THE ARGOS AREA IN PLYMOUTH COUNTY INDIANA. THESE TWO TORNADOES WERE BOTH RATED EF1 ON THE ENHANCED FUJITA SCALE. ADDITIONAL SEVERE WEATHER OCCURED THROUGH THE MONTH. ANOTHER WIDESPREAD WIND DAMAGE EVENT OCCURRED ON AUGUST 23RD ACROSS NORTHERN INDIANA AND SOUTHERN LOWER MICHIGAN. AN 81 MPH WIND GUST WAS RECORDED IN MICHIGAN CITY INDIANA DURING THIS EVENT. THE FOLLOWING DAY...AUGUST 24TH...SAW THUNDERSTORMS FIRE AGAIN ACROSS NORTHERN INDIANA AND MOVE INTO NORTHWEST OHIO. THIS LINE OF STORMS PRODUCED A DOWNBURST WIND WITH SUBSTANTIAL DAMAGE NEAR THE BARBEE LAKES AREA IN KOSCIUSKO COUNTY. THE LINE CONTINUED INTO OHIO PRODUCING WIND DAMAGE ALONG THE WAY.

 BELOW ARE SOME MONTHLY RAINFALL REPORTS FOR AUGUST AS REPORTED FROM VOLUNTEER OBSERVERS WHO PARTICIPATE IN THE COMMUNITY COLLABORATIVE RAIN HAIL AND SNOW NETWORK...COCORAHS. THESE SITES ARE CURRENTLY ONLY LOCATED IN INDIANA...BUT PLANS ARE TO EVENTUALLY EXPAND THE NETWORK INTO OHIO AND MICHIGAN.
