I received 10.36" in June, but it has dried out quite a bit(0.47" in July).  That has been the pattern in recent years.... very wet Junes that did not continue into July or August.

 

The record wet meteorological summer here will likely never even be approached again.  In met summer of 1993 Cedar Rapids received an astonishing 39 inches of rain.  I was a senior in high school.  It was a tough summer in which to take up golf, that's for sure.

The period June 15th-July 15th has been the wettest such period since records began in Columbus, with almost 10", and it doesn't seem to be in the heart of the worst of it. 

 

/\ heard this on the news yesterday... About a third of our average yearly rainfall in 4 weeks, pretty impressive.    But you also know if CMH is officially recording that much, than there are areas around here that probably have 12+".   Would love to know the actual jackpot amount and location for Ohio thru that period.

MESOSCALE PRECIPITATION DISCUSSION 0358

NWS WEATHER PREDICTION CENTER COLLEGE PARK MD

754 PM EDT THU JUL 16 2015

AREAS AFFECTED......NORTHERN AND CENTRAL ILLINOIS AND ADJACENT

MO/IA/IN...

CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE

VALID 162355Z - 170555Z

SUMMARY...THUNDERSTORMS WITH RAINFALL RATES UP TO 2" AN HOUR ARE

EXPECTED TO MOVE ACROSS NORTHERN AND CENTRAL IL TO ADJACENT IN.

FLASH FLOODING IS POSSIBLE WHERE CELLS TRAIN.

DISCUSSION...CLUSTERS OF SHOWERS AND THUNDERSTORMS HAVE FORMED ON

THE SOUTHERN EDGE OF A SHARP INSTABILITY GRADIENT WITH MIXED LAYER

CAPE VALUES OF 3-4000 J/KG

JUST IN ADVANCE OF THE CLUSTERS OF RAINFALL.

UPSTREAM, THE MODELS INDICATE DEEP SOUTHWEST FLOW WITH A JET MAX

PROGGED BY THE GFS TO BE 50 KT FROM 300 TO 250 MB CROSSING

NORTHERN KS, WITH EXIT REGION DIVERGENCE PROVIDING RISING MOTION.

STRONG DEEP LAYER FLOW OF 45 KT SHOULD RESULT IN STEADY

PROGRESSION OF THE CLUSTERS OF SHOWERS AND STORMS ACROSS NORTHERN

AND CENTRAL IL THIS EVENING...AND THEN CROSSING INTO ADJACENT IN.

PRECIPITABLE WATER VALUES OF 2-2.2" PER THE LATEST RAP ANALYSIS

AND GFS FORECAST PROVIDE AVAILABLE MOISTURE THAT IS 2 TO 2.5 STD

DEVIATIONS ABOVE NORMAL.

THUNDERSTORMS ARE EXPECTED TO PERSIST. THE SOUTHERLY COMPONENT OF

DEEP LAYER SOUTHWEST FLOW WILL BE OFFSET BY A NORTHERLY COMPONENT

OF PROPAGATION...RESULTING IN A EAST MOVEMENT. CELL TRAINING IS

THE MAIN FLASH FLOOD THREAT...CAUSED BY A SLIGHT INCREASE IN THE

850 HPA INFLOW.

THE 12Z ARW/NMMB/NSSL WRF AND HIGH RES RAPID REFRESH ALL TARGET

THIS REGION.

THE AVAILABLE MOISTURE, INCLUDING INFLOW WITH DEWPOINTS IN THE MID

TO UPPER 70S, SUPPORTS HOURLY RAIN RATES UP TO 2". THE HIGH RES

QPF GUIDANCE SHOWS MAXIMA OF 2-4" OF RAIN IN THIS REGION. FLASH

FLOOD GUIDANCE VALUES OF 2.5 TO 3 INCHES IN 6 HOURS RESULTS IN

WIDELY SCATTERED LOCATIONS EXPECTED TO EXCEED FLASH FLOOD GUIDANCE

VALUES.

1.61" at IND today, with what looks like more heavy rain about to move in there.

 

So, that puts them at currently the 6th wettest July on record.

 

1) 13.12" in 1875

2) 11.79" in 1992

3) 11.28" in 1873

4) 11.06" in 1979

5) 11.00" in 1872

6) 9.79" in 2015 (thru 6:00 PM today)

 

And now for summer, 2015 is currently the 4th wettest on record for Indianapolis. Of course, a little less than 1/2 of met summer to go. Pretty freaking incredible. 

 

1) 28.99" in 1875

2) 21.08" in 1979

3) 20.88" in 1876

4) 18.15" in 2015 (thru 6:00 PM today)

5) 18.00" in 1989

IND reported on their Facebook page that they were up to 3.01" about a half an hour ago. Not going to take long to overtake second place.

Make it 3.40" now which puts them at 11.58 and 3rd place with more storms coming in

MESOSCALE PRECIPITATION DISCUSSION 0360

NWS WEATHER PREDICTION CENTER COLLEGE PARK MD

224 PM EDT SAT JUL 18 2015

AREAS AFFECTED...AREAS AROUND SOUTHERN LAKE MICHIGAN

CONCERNING...HEAVY RAINFALL...FLASH FLOODING POSSIBLE

VALID 181823Z - 182223Z

SUMMARY...INCREASING INSTABILITY AND SUFFICIENT MOISTURE AND

INFLOW COULD LEAD TO FLASH FLOODING OVER SATURATED SOILS.

DISCUSSION...A WAVE ALONG AN OUTFLOW BOUNDARY SET DOWN BY A

DEPARTING SQUALL LINE HAS BEGUN TO INITIATE SCATTERED

THUNDERSTORMS OVER SOUTHWEST WI, WHICH ARE MOVING ROUGHLY EASTWARD

AT 25-30 KTS. MLCAPES OF 2000-4000 J/KG LURK ACROSS NORTHERN IL,

WHILE PRECIPITABLE WATER VALUES OF ~1.75" INHABIT THE REGION, AND

~30 KTS OF 850 HPA INFLOW INTERCEPTS THE BOUNDARY.

AS STORMS ORGANIZE, THEY SHOULD TURN EAST-SOUTHEAST AT 20-25 KTS

PER FORWARD PROPAGATING CONVECTIVE VECTORS. CELL TRAINING IS

CONSIDERED THE MAIN FLASH FLOOD THREAT. THE MESOSCALE GUIDANCE

HAS DONE POORLY IN THIS REGION SINCE YESTERDAY. THE BEST FIT TO

THE AVAILABLE MOISTURE, INFLOW, AND INSTABILITY APPEAR TO BE THE

00Z ARW AND 16Z EXPERIMENTAL HRRR, WHICH ADVERTISE LOCAL AMOUNTS

IN THE 2-3" RANGE. THE AVAILABLE MOISTURE SUPPORTS HOURLY RAIN

RATES UP TO 2", WHICH COULD FALL QUICKLY. SINCE SOILS WERE

RECENTLY SATURATED BY THUNDERSTORMS YESTERDAY AFTERNOON, THIS

DEGREE OF RAINFALL COULD LEAD TO FLASH FLOODING.

Just about every golf course is cart path only/should be closed. It's gotten to the point where the courses have to stay open to survive this year, it's gotten that bad. 

 

One of the benefits to being a member out at Belmont. They've been running multiple pumps all summer and have incredible drainage, the course is in pristine shape and only not allowed carts a few times. Still even then it still has not played all too firm yet

Pretty amazing stuff. Updated totals/rankings for Indy. 

 

July

1) 13.12" in 1875

2) 11.79" in 1992

3) 11.61" in 2015

4) 11.28" in 1873

5) 11.06" in 1979

6) 11.00" in 1872

 

Summer

1) 28.99" in 1875

2) 21.08" in 1979

3) 20.88" in 1876

4) 19.97" in 2015 

5) 18.00" in 1989

 

 

I updated Tim's post above with the numbers for Indianapolis through July 19.  Also, here's a list of the wettest June 1-July 31 periods on record:

 

 

25.33" in 1875

15.86" in 1992

15.02" in 1876

14.99" in 1979

14.98" in 1873

 

 

With 19.97" as of this writing, 2015 is guaranteed to at least be the second wettest June-July on record.  Bonus fact:  2015 is the wettest June 1-July 19 period at Indianapolis (1875 had 18.09" from June 1-July 19).

New July (and any month) rainfall record for Indianapolis. 1.25" has been recorded at IND today, through 11:00 PM, and that brings the monthly total to 13.13"...besting the previous record of 13.12" set in 1875.

 

Also, this summer now moves into 2nd place on the all-time wettest list. 

 

Wettest summers on record for Indianapolis:

1) 28.99" in 1875

2) 21.49" in 2015

3) 21.08" in 1979

4) 20.88" in 1876

5) 18.00" in 1989
