Thanks, tjc!

I'm watching that cluster of storms with hopes that the same perturbation, tracking along the periphery of the heat dome will dive south and bring rain to far southwest IN later today.

We've really dried out in my backyard part of the Cornbelt the past 3 weeks(missing rains all around us). I put down .10 of irrigation water last night on select sections of the lawn because it was deteriorating fast, to keep help it until potential rains this evening.

If we miss, it could be dry for awhile after that.

Yesterday in Evansville, IN(southwest corner), the storms stayed 50 miles northeast of us. 

However we had a strong outflow boundary  pushing way far southwest from the storms that came flying  thru in the evening that acted like a cold front would.

It was incredible to be outside and suddenly have this big wind shift and have the temp and dewpoint (Heat Index) immediately more comfortable.

Note the bottom line below is 7pm in Evansville, IN.

7pm: Temp 91, Dewpoint 74, Heat Index 101,  and Winds SW-6 mph.

8pm: Temp 80, Dewpoint 68, Heat Index 83,  and Winds E-13 gusting to 29 mph!

Most of this drop was within minutes. 

My wife(who doesn't spend that much time outside like me) was in the parking lot of her exercise class and noticed the same thing.

Great site for getting rainfall data. Just put in your zip code!

With extremely heavy rains it might be off by as much as 50% to the downside but its constantly updated.



Up to 1.7" of wonderful rain. I keep going outside in the pouring rain to check the last reading in the rain gauge in the backyard.

We've had some back building to the west that has resulted in the rains continuing.

We're on hill with a steep slope so much of this was runoff in some places.

UPDATE: Wayne County Emergency Management has upgraded the county to a Level 2 Travel Watch as flooding continues to impact the area. The travel watch is in effect until 5 p.m. Wednesday, Aug. 12. WAYNE COUNTY, Ind. - Significant flooding is impacting Cambridge City and other portions of Wayne County Wednesday morning as storms continue to move through the area. Wayne County Emergency Management has issued a Level 1 Travel Advisory through 5 p.m. Wednesday, Aug. 12, as high water and flooding create hazardous conditions. In Cambridge City, flooding has impacted Main Street — U.S. 40 — as well as homes along the roadway. West Main Street resident Tony Roberson shared video Wednesday morning showing extensive flooding outside his home, with water covering U.S. 40 and surrounding areas. As conditions worsened, Roberson reported approximately six feet of water in his basement. The Cambridge City Police Department also issued a flooding alert for Cambridge City and Dublin, reporting significant flooding throughout both communities. Police are urging motorists to use extreme caution and not attempt to drive through water when they cannot safely determine whether the roadway is passable. With storms continuing Wednesday morning, conditions and water levels could change quickly. Motorists are encouraged to slow down, allow additional travel time and watch carefully for standing or moving water on roadways. “Turn around, don’t drown,” police reminded residents. | The 765 | Facebook

Edit; Looks like maybe rain has stopped. Maybe the flood will spread out and not be as bad as predicted here. Hopefully!!

OH NO, cutworm!!!

Will crop insurance cover much of this if it did happen?

I noticed that you were in the red zone this morning.

https://www.weather.gov/iln/

Added: Since they are updating the graphics at this site, the "red zone" from earlier no longer exists.




Producers have one of the riskiest jobs on the planet and this is an example of how an extreme weather event can take out their crop, even when it looks most of the way to being made.

We got 2.1 inches of rain in less than an hour that stopped the damage.

Great to read cutworm's update that some of his crops will NOT get taken out by flooding!

We should all appreciate how producers can lose their crops for all sorts of weather reasons. 

AI Overview

 Various types of extreme weather damage crops by stunting growth, rotting roots, or tearing plants apart. The most destructive weather events include drought, heavy rain, and hail. [1, 2, 3]Temperature Extremes
  • Frost and Freezes: Ice crystals form inside plant tissues. This kills new buds, damages tender shoots, and halts early-season growth.
  • Extreme Heatwaves: High temperatures scorch leaves, cause sunscald on fruits and vegetables, and force plants to drop blossoms before they can produce a yield. [1, 2]
Moisture Extremes
  • Droughts: Prolonged dryness withers plants, dries out the soil, stops nutrient uptake, and causes complete crop failure.
  • Heavy Rainfall and Floods: Excess water suffocates roots by cutting off soil oxygen, washes away vital soil nutrients, and breeds harmful fungal rots. [1, 2, 3]
Storm Activity and High Winds
  • Hailstorms: Falling ice balls shred leaves, puncture fruit, and bruise or break delicate stems, completely ruining harvests in minutes.
  • High Winds and Tornadoes: Strong gales cause "green snap" (breaking stalks), uproot entire plants (root lodging), and tear protective foliage to pieces

  Ottawa, Il area is forecasted to have another inch plus starting 5pm.  Another inch on Friday. Had 1.7 Wednesday morning. Flood warnings issued for Fox and Illinois Rivers after 7pm

  I asked our tenant and he was NOT wanting anymore rain.  Corn this year.

  Cutworm, what is his reasoning?  (He would rather the rest of August to dry out so as to have 'normal' approach to harvest?  Or too wet affects stand?)

I was wrong hoping the flood would be less than predicted. It turned out to be the 2 nd or 3 highest on record. It easily was over the top of 9 foot tall corn. And covered everything in the valley. I lost about 225 acres

That's very sad news to read, cutworm! I'm so sorry this happened to you.

How much does crop insurance cover and how will they calculate the compensation?

I know that you probably have the answer but am just sharing this below for basic information for readers. Much of it applies to flooding that impacts planting in the Spring, which I'm guessing were the other times you had flooding to this area(but maybe not). 

AI Overview

 Farmers with crops destroyed by flooding can file a claim through federal crop insurance overseen by the USDA Risk Management Agency (RMA). You must notify your crop insurance agent within 72 hours of discovering the flood damage and submit your follow-up notice in writing within 15 days. [1]Immediate Steps After Flood Damage
  • Contact your agent: Report the loss immediately before altering the field or destroying any representative crop samples. [1]
  • Wait for an adjuster: An approved insurance provider (AIP) adjuster must inspect the flooded acreage and release the land before you can replant, switch crops, or destroy the damaged crop. [1]
  • Keep caring for crops: Continue normal crop care on unaffected or marginal areas until the adjuster appraises the field and gives written direction. [1]
Your Options for Flooded Acres
  • Replant: If it is still early enough in the season, you may qualify for a replant payment to replant the same crop or a short-season variety. [1]
  • Prevented Planting / Total Loss: If flooding stopped you from planting entirely or completely destroyed the crop with no option to replant, you can claim a prevented planting or total loss indemnity payment through your policy. [1]
  • Switch Crops: Planting a second crop (like soybeans) on the flooded acres may adjust your indemnity payout percentage for the first crop depending on your specific revenue or yield protection terms

++++++++++++++++++++++

AI Overview

 Crop insurance payouts for floods are calculated based on your choice of Yield Protection (YP) or Revenue Protection (RP). Indemnities equal the insured guarantee minus actual harvested production or revenue, determined by your Actual Production History (APH), the selected coverage level (50% to 85%), and set market prices. [1, 2, 3]How Yield Protection (YP) is Calculated
  • Find your APH: The insurance company looks at your average yield per acre over 4 to 10 past years. [1]
  • Calculate the Guarantee: Multiply your APH yield by your chosen coverage level percentage (e.g., 150 bushels/acre × 75% coverage = 112.5 bushel guarantee). [1]
  • Assess the Loss: The adjuster subtracts what you actually harvested from your guarantee.
  • Determine Payment: If your actual yield falls below the guarantee, you are paid for the missing bushels multiplied by a pre-set base price. [1, 2]
How Revenue Protection (RP) is Calculated
  • Establish Base Revenue: Multiply your APH yield by the board price (projected market price set in spring).
  • Calculate Revenue Guarantee: Multiply the base revenue by your coverage level (50%–85%).
  • Compare Harvest Revenue: At harvest, final market prices are used to value what you actually grew.
  • Determine Payment: If your final crop revenue falls below your guaranteed dollar amount due to the flood, insurance pays the difference.

++++++++++++++++++

No doubt there are a dozen nuances that make it very complicated but at least it won't be a total loss. You probably wasted a bunch of money on nitrogen if it's corn or other chemicals spraying if that was done.

Here is a map that shows total rains the past. Top map is a snap shot. 2nd one is constantly updated.  Cutworm lives just south of the epicenter in southcentral/southeast Indiana. 

I'm having a tough time discerning the value of the darkest brown epicenter but will check other data sources. It's at least 10 inches but could be much more.

I have a big problem with them abusing the term "1 in 100 or even more crazy, 1 in 1,000 year rainfall events"

AI Overview

 The all-time state record for the greatest 24-hour rainfall in Indiana is 10.5 inches, recorded in Princeton on August 6, 1905.


At the very least, if you want to call a rain event 1 in 100 year event, it should be close to the record for that state. That was the case here. 8.23 inches of rain at 1 place in 24 hours was close to the record of 10.5 inches.

To be a 1 in 1,000 year event, it should completely blow away the previous state record. CNN and others are extremely abusing that term here. 

Isolated extreme rains in 1 spot like this happen every year in different locations. THEY ARE AN EXPECTED PART OF CLIMATE but happen in different places each year from natural variation. Expected, almost annual ISOLATED extreme rain events that happen in different locations each year are NOT all 1 in 1,000 year events. They are part of natural weather variations/climate.


https://cliffmass.blogspot.com/2016/03/the-golden-rule-of-climate-extremes.html

The GoldenRule

 Considering the substantial confusion in the media about this critical issue, let me provide the GOLDENRULE OF CLIMATE EXTREMES. Here it is:

The more extreme a climate or weather record is, the greater the contribution of natural variability.

Or to put it a different way, the larger or more unusual an extreme, the higher proportion of the extreme is due to natural variability.

We got 2.1 inches in our rain gauge in the southwest corner in an hour on the 12th even though this map shows 1.3 inches, so its possible that there were spots with even more rain than this.

Another round of heavy rain where it’s not welcome. Might as well keep the same thread going since it already has the links to cover the same areas.

Sorry for the excessive length.

We got another 2.1 inches overnight. Last week's heat accumulated alot of GDD's and caused heat fill for the corn which doesn't need any more rain this year in this neck of the woods.

The beans might benefit slightly from 1 more rain but they are basically made too.

Thanks a ton, cutworm!

We're having another heavy rain event tonight in some of the same places but more PROGRESSIVE.

The ground is saturated so it's not taking much additional rains to cause excessive running and flash flooding.

This should be the last big rain event for the next 10+ days.


You can use the same links above to track tonight's event!


Excessive rain threat.
