That sounds delightful, Jo! It's similar to the weather we've enjoyed the past few days.

Local lore says that the Minnesota State Fair - which opens this Thursday - always has some hot days. And just in time, the forecast calls for 90F/32C both Saturday and Sunday, with high humidity. (Unusually for August, the last 90 degree day we had was August 2. Usually we have more).

Everything remains green and lush with all the rain that continues to fall.

We've had some hazy skies the past week with wildfire smoke returning - but it's nothing like last summer, when it often reached ground level and was sometimes so thick you could smell it.

Here, too, stargazer, our temperatures will be ramping up gradually on Saturday through next Wednesday. Until then, though, as mentioned, our days, and especially nights, are very comfortable. This early morning's forecast was 9° in town, which pretty much always means one or two degrees cooler here in the country. Sure enough, I awoke near 5 am to 7°C / 44.6F - very fresh, crisp, and invigorating for this morning's walk, which began under the glorious night sky (see Astronomy topic) and ended an hour later near sunrise.

Near my favourite night sky viewing spot, as the dawn grew, the grass surrounding the farmer's field looked like it had a white sheen. I thought at first frost, yet how could that be at 7°? I then saw (and felt) that it was very heavy dew, which would have been frost not many degrees lower.

We are planning another campfire for this Friday, before the heat comes for a few days, and it should be lovely weather, with no humidity and cool at night again. Saturday and Sunday all that changes, but it won't last too long, thankfully.

We've been having some rather unusual late summer thunderstorms rolling through our area the last few weeks. No complaints from me here! Though the trade off from the rain-cooled temps is higher humidity and I'm not a big fan of that part.  

The heat index just dropped below 100. It's almost 10 p.m.. Six days until rain chances possibly go up. 24 hours until we drop back below 100F for the high. Hopefully, the heat index will go down to 110 instead of 113-121F. 

5.5 weeks until the days are too short for the heat to last this long into the evening. 

I melted this last weekend. 

Whew! Hope you are keeping cool, @starkat!

(in 5.5 weeks we may be looking at snow around here. 😉 Not extremely likely by the end of September, but certainly possible).

We had a taste of your weather yesterday, with a high of 91F/33C and a heat index of 110F/43C. Stepping outside was like walking into a wall of stifling, humid air, and the glasses fogged up right away.

in the early evening a vigorous but brief thunderstorm rolled through. Around 8pm local time, with lightning still flashing and a few stray raindrops, a double rainbow appeared in the east, and the western sky blazed with a vivid, unusual shade of orange that lasted only a few moments as the sun set. Beautiful!

@stargazer thankfully, we've been given a break with some rain. We're running between 85-93 ish for highs depending on how much rain and how long it rains. The cloud cover has been a nice break.

@starkat: The heat index just dropped below 100. It's almost 10 p.m.. Six days until rain chances possibly go up. 24 hours until we drop back below 100F for the high. Hopefully, the heat index will go down to 110 instead of 113-121F. 

That is to say, you've been having temperatures as high as 40-50 degrees C. That bodes ill for summer temperatures here, in the Southern Hemisphere, when it is already quite warm about midday, even though Spring doesn't officially start until Sunday, this week. This morning it was still 10C though it was more like 30C by mid-afternoon. 

And meanwhile in England, summer has been a bit of a wash-out... there were a few spates of warm days here and there, but nothing that I as an expat Aussie would consider uncomfortably hot. I think it only went over the 30 C mark a handful of times, and only in the South, not in the North (where I live). Hard to believe that only two years ago we had the UK's highest-ever recorded temperature of 40.3 C (in Lincolnshire), which I thought might be instructive to the great British public as to what a real heatwave feels like. But no, now we're back to them considering it "a scorcher" if it goes above 26 or so.  

The summer here in Michigan has not been a very hot one with only a few days of 90 degree Fahrenheit weather. This week it has just been around 85 degrees with some humidity but not too much. I am very happy without any extreme heat. It’s more comfortable for taking walks in the parks.  🙂

The summer here in Michigan has not been a very hot one

Ditto here for Ontario. What a relief. Plus, this summer has set a record for the most rainfall for our area in recorded history. I am so not complaining!

Today ends our very short streak of warmer weather (as in two days). Having said that, nighttimes have been nice and cool - great walking weather in the hour as dawn and sunrise approach. Rain comes tomorrow and a bit into Saturday morning (lots of it!), with noticeably cooler temperatures all weekend. Saturday night is going down to 4°C / 39.2F, which means in the more rural area where we are, frost might be a possibility!

The early-turning trees are blushing colour at their ends, a portend of the utter beauty that is to come. I love Autumn!!!

The past few days have had spectacular late-summer weather, with comfortable highs, no humidity, and no mosquitoes. The only hitch to hours of stargazing (as the sun sets earlier and earlier each day) is some haze from wildfires (though nothing like last year's levels).

Summer's not ready to give up, however, with highs approaching 90F/32C later this week. At least the humidity is expected to remain fairly low, making it a lot more comfortable.

Summer's not ready to give up,

True here too. Unfortunately. We are currently experiencing a lengthy stretch of hot, dry weather ... the weather we never had all summer. I guess it's catching up to us now. Ah well, in another couple of weeks we should be in full-blown Autumn weather, so ... I'm counting the days! This is the longest spell we have gone this year without any rain, by far.

The only difference between what this would be in July and what it is now, is that the current nights are nice 'n cool, whereas in July, the overnight temps would be a very muggy 20C or so (68F). So, the nights are a relief now, hence I can still have my early morning walks, for the most part.  

But with the hot days and cool nights, we have been inundated with fog in the early hours. This morning's was particularly heavy, both on my walk, and even moreso when I drove into town at 8 am, an hour after sunrise. The countryside was much worse than town (visibility was extremely poor), although there were some sections in town where one had to really slow down, and drive with great caution. Now (10 am EDT) that the sun has been risen for three hours, it is burning off the fog, but the radio meteorologist said this morning that this hot daytime air has stalled above us for quite a long time. Unusual here for September.

More and more trees are beginning to show the faintest blush of colour, and this will only increase over the coming weeks. Very pretty! I am hoping that, because of this rare September long warm spell, our trees will be at their peak around our Thanksgiving weekend (second wknd of October), but it might be later this year. Time will tell!
