July 12th and Beyond Heatwave

[Powerball]

Funny thing is, while humidity will be lower, there's likely a better shot at 100s with this round compared to the last one, with the peak currently projected to be Tuesday/Wednesday. Duration is a lot more questionable though (especially with NE extent).

Looks low end

Euro throwing up some wild numbers for Wednesday.

Looks super funky with a pocket of dewpoints  in the 50s! 

102/55 ORD

For me personally if it’s gonna torch I’d rather it be a very dry heat like this. Evaporative cooling FTW!

They upped the temps the next few days from around 90 to mid 90's here in town. SW winds will bring hot air, along with some down sloping effect from the ridges. We'll see how this pans, but it'll be nasty without A/C.

Do you not have any AC?

No. Just fans. It never stays hot long enough to really need it. 

[Brian D]

Around 80 on the shoreline to upper 80's inland today. Dews upper 60's to low 70's. Mid 80's imby. Tomorrow starts the really hot stuff. We'll see how much.

The warmest 850 temps are actually north of Chicago at the beginning of the week. I think this has potential to see some actual temperatures that are the highest we’ve seen in years for Michigan, Wisconsin and Minnesota. The funny part is there probably won’t be the media hype that we saw leading into the 4th of July since the dewpoints will be much lower leading to a lower heat index which leads to probably nothing worse than heat advisories. 
 Of course everyone on this board knows that you need the lower dewpoints if you want higher actual temperatures. 

[Geoboy645]

Yeah this is looking like a potentially very significant heatwave for the northern areas of the subforum. Temps look like they will max out in the upper 90s or even the rare 100s. There has been like 5-6 heatwaves that have led to 100s that far N, and unlike those ones it won't be that hot here as well. Paradoxically, you will have to go south to cool off early next week. This heatwave also coincides with the peak tourist season up N, which could compound heat effects as people are in cabins or campers that are not equipped to handle a couple of days in the upper 90s-100s with 70 degree lows in between. 

[A-L-E-K]

Yeah should have specified imby, somewhat odd looking ridge, good luck to our friends up northwest breaking some records

For as inexpensive as a small window ac unit is, I would have one available to use even if i only needed for a handful of days a year just because I hate sleeping in a hot room. It’s not like I have to use my ac all summer here either but for those really warm nights, I would be miserable the next day if I didn’t have it. It seems like the older i get, the less  tolerant I am of hot or cold. lol.

You wanted heat for your garden. Your vegetables will be coming pre-cooked.

Yeah, I get it. I keep the windows closed during the day, open at night. It's not terrible. If I can't stand this, this year, then that will happen. At some point tough isn't enough. Will use wet towels with a fan blowing, if I really need too. After this tho, 70 will be frosty LOL

Just visualize the massive snow drifts that will be back in 4-5 months.  That should help a bit.

Point up to 98 tomorrow, 92 today and 94 Tuesday. Three days of 90's with 70's at night is gonna be hard.  House is 66 degrees this morning with all the windows/blinds closed.  Thankfully it's well insulated, and I have plenty of shade later in the day.  More concerned for my chickens and rabbits than I am myself.  Gave the garden a good soaking this morning and put a shade tarp over it to mitigate some of the heat stress.

90 yesterday. 4th of the year for MSP. Spent the day floating the Cannon River.

Its probably a good idea to invest in a window air conditioner. They aren't that expensive and even on days when it just hits 80 you can turn it on for a bit.

I rarely ran my AC the last 3 weeks of June. I had it set to 80 when I was in Alaska and then when I got home I turned it off the next 2 weeks. Turned it back on ahead of the June 30-July 3 heatwave and havent had it off since.

97, 98, 95 today, tomorrow, and Tues. 75 in the house atm. Looks like WSW light wind the coming days, so that should keep the shoreline pretty warm, too. 

[Brian D]

Temps peaking right now at 92/71/98. General low/mid 90's around here with 80's along the shoreline. Still only 79 in the house, so doing good. Will open the windows later after sunset.

High of 90 today. Dews have crept up into the low 70s this evening. 

[A-L-E-K]

locked in

[Brian D]

Suppose to be the hottest of the heatwave today. Lets see if anyone hits 100. As noted below, the Lake cooled some with SW winds yesterday, so that might keep things in check here in town. Winds are to be breezy out of the SW again. 

.UPDATE...
Issued at 253 AM CDT Mon Jul 13 2026

We remain trapped under the influence of a stout upper level high
pressure today. With 2AM temperatures still in the 70s across the
Northland (outside of some areas right along Lake Superior on the
North Shore), today will provide little to no relief from the
ongoing heat wave. Guidance continues to point towards today being
the hottest day of the heat event. High temperatures could touch or
even exceed 100F for the Borderlands in Koochiching, northern St.
Louis, and inland Lake/Cook Counties while high temperatures in the
90s are expected across the rest of the Northland. An Extreme Heat
Warning continues through the day for the entire area except Price
County. The Extreme Heat Warning for areas along and south of Hwy 2
in MN and everywhere in NW WI except Price County has been extended
through Tuesday evening due to another very warm night and afternoon
expected in those areas. Once the warning expires for the areas
north of Hwy 2 in MN, a Heat Advisory will likely be needed at least
through Tuesday evening there. In Price County, the Heat Advisory
has been extended to run through at least Tuesday evening. A Heat
Advisory may be needed along our southern tier of counties for
Wednesday. One small note of uncertainty: there has been significant
upwelling of cold water in Lake Superior from Duluth to Two Harbors
due to the southwest winds over the last 24 hours. This could affect
temperatures today very close to the lake, similar to the
extremely tight temperature gradient we have seen further up
the North Shore. For now, have opted to stay on the hotter side
for much of the forecast.

[Powerball]

100*F+ seems fairly likely for Detroit tomorrow. About as perfect as a setup as you can get...

[A-L-E-K]

something about 100+ in detroit and 89 imby feels weird but i'll take it

[weatherbo]

90/75 and as still as can be.
