June 2026 Observations and Discussion.

[westMJim]

Here in my yard it was warm overnight with a low of only 72, there was 0.34” of rainfall. At 7:30AM there is light rain falling and a temperature of 72. Today will be generally cloudy with showers and maybe a rumble of thunder and a forecasted high of 83. Tonight should see a low in the mid 60’s Wednesday will be very warm with a forecast high of near 90, there should be around a 40% chance of showers and thunder. Wednesday night should see more showers and maybe a storm or two  and a low of around 70. Thursday and Thursday night could be stormy, we shall see, The rest of the next 7 days will turn cooler with highs in the 70’s and lows in the 50’s.

The official H/L yesterday at Grand Rapids was 86/62 there were 9 cooling degree days, that 86 is the warmest high so far in 2026 at Grand Rapids. There was a reported trace of rainfall.  For today the average H/L is 78/57 the record high of 93 was in 1964 and 2022 the coolest high of 57 was in 1937 and 1915. The record low of 37 was in 1969 the warmest low of 72 was in 2004. The most rainfall of 1.77” was in 1963. Last year the H/L was 78/55.

Some weather history for June 9^th 1953, The system that caused the Flint tornado on June 8^th moved east and cause A tornado hit the town of Worcester MA killing ninety persons. The northeastern states usually remain free of destructive tornadoes, however in this case a low pressure system, responsible for producing severe thunderstorms in Michigan and Ohio the previous day, brought severe weather to New Hampshire and central Massachusetts. The tornado, up to a mile in width at times, tracked 46 miles through Worcester County. It mangled steel towers built to withstand winds of 375 mph. Debris from the tornado fell in the Boston area, and adjacent Atlantic Ocea. (David Ludlum) (The Weather Channel) 1972, A cloudburst along the eastern slopes of the Black Hills of South Dakota produced as much as 14 inches of rain resulting in the Rapid City flash flood disaster. The rains, which fell in about four hours time, caused the Canyon Lake Dam to collapse. A wall of water swept through the city drowning 237 persons, and causing more than 100 million dollars property damage. (David Ludlum) Here in Michigan 1963,  Severe thunderstorms caused millions of dollars in damage across the region as winds gusted over 70 mph. There were also reports of funnel clouds and a possible tornado in Belmont where several trailers were destroyed and homes were damaged. A tornado near Dorr heavily damaged a house.

Temperatures today will be close to average for the date with highs well into the 70's to near 80 degrees. We start a warming trend tomorrow with the peak hot day being on Friday which is the only day that higher elevations have a shot a 90 degrees. Most valley spots should reach the 90's Thursday and Friday including higher humidity. While we will cool by a few degrees over the weekend it will remain hot until Monday when temperatures will fall back toward the middle 80's. We have shower chances tomorrow morning and again both Thursday and Friday afternoon.

[westMJim]

There has been several rounds of heavy rain here in Walker and I have had a total of 0.97” of rainfall last night and into today so far.

[Clinton]

I got a half inch of rain with thunderstorms overnight and this morning.  The sun is out and the heat is on!

[mlgamer]

Greetings from the swamplands!

I measured 3.6" of rain this morning from the evening and overnight storms. I have had 9.35" of rain in MBY over the past 12 days counting today. 

The ground is really soggy and more rain chances ahead this week. Maybe some cooler and drier weather on the way next week...hope it pans out!

[Hawkeye]

There is some hype about potential severe weather Wednesday around here, but the models are showing a giant nothingburger for Iowa.  All of the CAMs have the storms in Illinois and Missouri, despite the front being well to the nw.

[jcwxguy]

Models show pretty much nothing here tonight yet ...

[Clinton]

Hot and sticky today.  Models showing 2-4+ inches of rain over the next week.  We are now about 10 days behind on hay season and could use a few dry weeks.

Crazy that I only have .90 since may 18th, while INCHES FALL IN MANY AREAS. On monday i worked on a missouri farm west of kirksville and the place was a swamp! Tropical, wet and lush vegetation.  Meanwhile I worked on a farm ene of Ottumwa 12 miles and was very dry!  While all i hear is flood watches, super cells and today a 111F heat index and 82 dewpoint it wont suprise me if we get drier and drier. Check out the model this eve used by kcci news from desmoines. This hell hole  may pull off pne of its greatest DRY VICTORIES EVER JUNE 2026!

[westMJim]

I had several rounds of heavy rain here in my yard over the last two days. Yesterday I had 0.63” of  rainfall and the night before I had 0.34” of rainfall for a event total of 0.97” The overnight low here in my yard was 69 and that is also the current temperature. Today looks to be on the very warm side with highs near 90 tonight there is a good chance of some thunderstorms with a low around 70 tomorrow looks to once again be very warm with highs in the upper 80’s and another good chance of storms tomorrow night. Some storms could be severe. Friday into next week look to be on the cool side with highs only in the low to mid 70’s and lows in the 50’s Saturday and Sunday could see some showers.

The official H/L yesterday was 81/71 there were 12 Cooling Degree Days. There was officially 0.47” of rainfall.  For today the average H/L is 78/57 the record high of 93 was in 1933 and 1999 the coolest high of 60 was in 2011 and 1980 the record low of 36 was in 1980 the warmest low of 74 was in 1911. The most rainfall of 1.37” was in 1979. Last year the H/L was 68/52.

Some weather history for June 10^th 1988, Three dozen cities, mostly in the eastern U.S., reported record low temperatures for the date, including Elkins, WV, with a reading of 33 degrees. Unseasonably hot weather continued in the Northern High Plains Region. The record high of 105 degeees at Williston, ND, was their seventh in eight days. (The National Weather Summary)

 

[Clinton]

A rough couple of days for the Midwest with tornadoes possible today and tomorrow.  

Tomorrows threat has a lot of the same areas.

Day 3

Slight risk day Saturday evening for KC. 

Rainfall totals for the next week.

[chescowxman]

We are only running around 80% of normal rainfall for the year to date here in East Nantmeal. It looks like we should see at least some showers and thunderstorms today that could give us some welcome rain. A heat advisory goes into effect tomorrow with highs both Thursday and Friday in the low 90's with increasing humidity. Shower chances will be around both later in the day Thursday and Friday. The weekend looks cooler but still warm before we turn much cooler to start the new work week. Temperatures both Monday and Tuesday may only be in the 70's for high temperatures.

[Niko]

Attm, its 85F under hazy sunshine w humid conditions. Storms are possible later this afternoon.

Note: there were 3 confirmed tornadoes yesterday in Wayne county, I think and nearby areas. Crazy! 

About 45min or so south from my area. I just received torrential downpours and lightning w very soft far distance thunder.

All of those maps a useless  ball of garbage to me!  Missed by few miles to my east this am.

I got .17"

[Tom]

So your saying there is a "chance"???  My 1st taste of the Monsoon and higher DP's...its gonna feel a bit muggy late week into the weekend.

[Hawkeye]

I got a quick 0.51" of rain from the line.  It was fairly windy, but the line wasn't yet very organized when it passed through here so there was nothing severe.

[summerrules]

fairly decent wind reports with the storms just to the NW.

[BMT]

1.25” from round 1.  Good start

[Hoosier]

First 90 degree day at ORD this year (91 so far)

[Hoosier]

LOT issued a severe thunderstorm warning all the way to the IL/IN border for a line that is still about 75 miles away from the state line.  Not sure I have seen that too many times before.

[OttumwaSnomow]

I got about .85" all day. Rain all around me.  But nothing severe, and look at this map. No one will ever change my mind most likely a geographical explanation.

[Jaycee_CHI]

Awesome start to this two day outbreak! Was all positioned properly on the 18th street bridge but sadly had to pack up and leave due to a very creepy man refusing to leave me alone :( but was still able to readjust and snap a quick time-lapse after the fact! 
 

I’ve been waiting for years for a day-time squall line to come through downtown, so grateful I had the chance to see one today

I was watching the radar and it looked like a sure thing you'd get clobbered, but once again all of those storms were mostly diverting just north and south of Ottumwa.  It's likely areas north of you will be hit by a strong line Thursday morning, but Ottumwa and points south might get missed.  

[beaugie]

Ended up with 1.2" of rain so far. Had some 60+ mph winds in front and almost no lightning. Just missed on round 2, light sprinkle and a rumble or two. Guessing the stuff west of us doesnt hold up. 

 

Just hoping for more rain tomorrow. April was so great (record high) with basically 3 days doing the heavy lifting and May was so bad (record low). I just want an above average June and normal July. 

 

[westMJim]

Here in my yard yesterday’s storm event was really a non-event. There was maybe a 25 MPH wind, moderate rain at best, and in my yard I did not notice any thunder or lightning. I had a total of 0.28” of rainfall yesterday and overnight. Today we have another chance of some severe weather so keep a eye out for that this evening. Today should be warm again with highs in the mid to upper 80’s then there is the chance of storms tonight with lows near 60. Friday and Saturday look to have highs in the upper 70’s to mid 80’s Sunday will be cooler with highs only around 70 and the next week the cooler temperatures will continue with highs in the low 70 to mid-70’s and lows in the 50’s and there are several chances of showers.

The official H/L yesterday at Grand Rapids was 89/69 there were 14 Cooling Degree Days. There was 0.11” of rainfall. At the airport there was a wind gust of 50MPH. Some weather events yesterday at GRR were Thunderstorm, heavy rain, rain, fog and haze. For today the average H/L is 78/57 the record high of 93 was in 1894, 1933 and 1956 the coolest high of 60 was in 1963 the record low of 33 was in 1972 the warmest low of 71 was in 2017. The most rainfall of 2.64” was in 1986. Last year the H/L was 84/50.

 

[Hawkeye]

This morning's MCV rolling through Iowa this morning appears to be a bit father south than models were predicting yesterday.  The worst of any severe wind should stay south of me.  Hopefully, I can get some more good rain.

This is a hellova nasty bowed line of storms that has eyes for your area...you might score a 1-2 punch as the CF makes its way through later today.

I saw some vids from the intense winds that ripped through the city of Chicago last night.  Ton's of trees down and power outages.  Here's a short clip on Instagram.

Edit: Just read the report of 85mph wind gusts in Downtown Chicago and up to 94 mph in Oshkosh, WI!

It could get wild here later today!

Possible deracho?  Heads up northern Illinois SPC went to a moderate risk.

Cedar Rapids got into the comma head, where the heaviest rain is.  I got a very quick 1.25".  It was the heaviest rain I've seen in a while.

I would define this as a derecho. My pics and vids do no justice to the wind we had. Pea size hail only mby.

But rain? Yes!!! This am didnt miss! Yesterday while less than most in my area i did get .96" in 24 hrs.  Then today almost 1.5"

So in about 27 hrs Ive had about 2.5"!!

Wettest time since July 2025.

But have you seen the deluge in north central missouri!!!

And pockets of 10" near me in June. Im at about 3.25" in June. The ambient gage screen isnt accurate but gives you a idea.

Pic below are mine and friends of mine.

Was all the Corn damage caused by wind or was there some hail?  That's a total loss.

Hail and wind. Wasnt mine.  Some of my sweet corn is knocked down. I still have to inspect it.
