Drought in Lower Lakes/Ohio Valley


Geos

Recommended Posts

With this much of the country in moderate or worse drought it shouldn't be a surprise how the ridge pattern has done a pretty good job maximizing its potential.

I've never seen such widespread drought conditions before! We need to open up the Gulf again.

By reading these two articles, it sounds like if it doesn't rain significantly this week the corn in NE IL will be no good.

I'm not sure if this number is official but I am seeing 1.29" of precip for Indiana for June. IF that number is accurate, then this year is the 6th driest through June out of 118 years of records.

Driest January-June periods:

1934: 11.36"

1895: 12.54"

1988: 13.14"

1925: 13.17"

1936: 13.39"

2012: 13.57" ???

Illinois Drought Update - July 3rd. http://www.isws.illi...ate20120703.pdf

The statewide average precipitation for June was 1.8 inches, which is 2.3 inches below normal and 43 percent of normal. It was the eighth driest June on record. June 1988 was the driest on record at 1.1 inches.

The statewide average precipitation for the first half of 2012 was 12.6 inches, making it the sixth driest on record. The first half of 1988 was slightly worse at 12.0 inches. The driest January-June was 1934 with only 10.3 inches.

Statewide precipitation deficits since January 1, 2012, (Figure 1) have grown to 4 to 6 inches across northern Illinois, 6 to 10 inches across central Illinois, and 10 to 12 inches or more in southern Illinois.

As of today, one household down the block from me has a dry well! Will either have to get a water delivery or have their well drilled deeper/or pump lowered if there is space to do so.

There's a large grass fire currently ongoing near Paddock Lake, WI.

Smoke shows up well on KMKX/KLOT.

There's one in Sheboygan County also. These brush fires will become more common if this pattern continues!

...There was a fire in Racine County on the 6th too. Didn't hear about that one. http://www.wisn.com/news/south-east-wisconsin/racine-kenosha/-/10151828/15432922/-/fot6h9/-/index.html

Wow they average 26" of rain by this point? That's almost 7" more than MLI averages.

Yep, I had to double check to make sure. 47.36" for the year for Bloomington.

For comparison, Indianapolis "should be" at 22.90" through yesterday...and has a yearly average of 42.44". On the other hand, LAF "should be" at 19.22"...and has a yearly average of 36.58". Quite a range from north to south, approximately 110 or so miles apart (LAF to BMG). Of course, I know LAF is missing a good amount of precipitation data, as well I'm sure BMG isn't 100% accurate either...

I'm not gonna argue the reason for it, but with precip trending upward over the years, the fact that we are bumping up against these all-time driest years (year to date) is even a little more impressive imo.

I'm not sure there has been a bigger drop, from one year to the next, for Indiana in the January-June period like from 2011 to 2012.

2011 was the 3rd wettest such period on record (since 1895), and now 2012 is the 6th driest. Amazing.

Top 10 driest January to June periods for Indiana (statewide average precipitation), and what happened in each year thereafter.

1895-2011 row that is highlighted in yellow are the averages for Jan-Jun, each month that follows including the Jul-Dec average, and annual totals. Yr Rank in the last column is how the annual precipitation total ranked (in terms of driest).

Probably not. As bad as it's getting it would be even worse in some regards if last year wasn't as wet.

Models are getting more bullish with precip north of the Ohio River in the extended. Would at least hold the drought in check locally and possibly help put a dent in some areas but evaporation rates are so high at this time of year that it's difficult.

1 week rainfall

post-14-0-04972400-1341943698_thumb.png

Normal weekly rainfall should be something like .8-1.2" depending where you're at. Anybody who got less than that in the past week fell further behind. Would not be surprised to see significant expansions on the next drought monitor.
