Torchageddon Posted Monday at 12:49 PM Share Posted Monday at 12:49 PM Yesterday I got to 33C/90F, Heat Index of 50C/122F, Humidex of 44C/111F. Air temp was standard for a heat wave but the humidity is extreme. I don't ken last year getting these values maybe not even for several years. Overnight low under-performed at 23C, clear blue skies already 29C humidex of 37 . Point today also 33C. 1 Link to comment Share on other sites More sharing options...
sbnwx85 Posted Monday at 03:54 PM Share Posted Monday at 03:54 PM IWX kind of on an island issuing an Extreme Heat Warning but with the overnight lows being so incredibly warm, I think it’s the right call. Link to comment Share on other sites More sharing options...

To be fair, the bigger metros with UHI effect (Chicago, Detroit, St. Louis, Milwaukee, Pittsburgh, etc.) are also under Excessive Heat Warnings. 1 Link to comment Share on other sites More sharing options...
roardog Posted Monday at 05:09 PM Share Posted Monday at 05:09 PM The impressive part of this heat wave is just the atmosphere staying well mixed during the night causing such high minimums. The fact that we're so close to the most daylight of the year probably helps too. The high temps haven't been anything special at all around here.

OrdIowPitMsp Posted Monday at 05:35 PM Share Posted Monday at 05:35 PM 79/66 currently with summertime cumulus. Big difference from this time yesterday when we were 91/74. Link to comment Share on other sites More sharing options...

The high temps have underachieved each day, although you and I discussed that as a likely scenario before the heatwave even started. Yesterday was surprisingly more oppressive than today. I expected today to be the worst. Link to comment Share on other sites More sharing options...
Torchageddon Posted Monday at 08:29 PM Share Posted Monday at 08:29 PM Its nice out there but hotter air temp wise, my station got briefly to 35.3C/95F, humidex of 45C also higher than Sun. RH lower. Almost no clouds at all, and getting windy. I wish I could ken how windy my other mid-30 readings have been because it seems unique. Link to comment Share on other sites More sharing options...

I made that post at 6:30 before I was fully awake and didn't articulate fully what I was trying to say. IWX also mentioned they went with a warning since it's the first heat wave of the year.

Chicago Storm Posted Monday at 10:51 PM Share Posted Monday at 10:51 PM Gotta say, the Euro has done horribly with its handling of mixing during this period. It has been way over mixed and way too high with projected temps. In the short term, the HRRR has been stellar. 3 2 Link to comment Share on other sites More sharing options...

TheClimateChanger Posted Monday at 11:42 PM Share Posted Monday at 11:42 PM Several records set or tied today, including Cleveland, Detroit, Toledo, Saginaw, and Mansfield. The 96F reading at Saginaw was the warmest of any day in the past 13 years. Alpena set a new daily record high of 97F. If it stays at or above 79F through midnight local time, it will set a new all-time record high minimum & the daily mean (average of high and low) would be the second highest in the threaded record behind 88.5F on August 25, 1948.

I’m not sure what the official high was there. They’re helped by downsloping though. Link to comment Share on other sites More sharing options...
Chicago Storm Posted yesterday at 12:30 AM Share Posted yesterday at 12:30 AM Got up to 95° at ORD and at MDW today. 1 Link to comment Share on other sites More sharing options...
michsnowfreak Posted 23 hours ago Share Posted 23 hours ago Detroit hit 95° today, which tied the record from 1923 & 1911. Today's record was fairly low hanging fruit compared to all surrounding dates. As expected, this heatwave will be much more noteworthy for its lows than its highs. The highest for Detroit should be today's 95°. By comparison, since 1874 there have been 197 days when the high was 96° or hotter. Link to comment Share on other sites More sharing options...

Yep, today's 94° with a 66° dewpoint did feel marginally better than Sunday's 90/72. Marginally. Went down to Crescent Lake earlier this evening and dicked around for awhile in the swimming area on the north shore. Felt like bath water. Stepped on a zebra mussel, which I do not recommend, was nice knowing you guys 2 Link to comment Share on other sites More sharing options...
nwohweather Posted 14 hours ago Share Posted 14 hours ago I feel like I’m back in South Carolina with this heat wave. Pretty impressive to see these level of dew points Link to comment Share on other sites More sharing options...
Torchageddon Posted 13 hours ago Share Posted 13 hours ago Transcended the point low by 1C - 24C/76F. Tues I was peg to be 26C high, every check it's increasing: went to 29C, now 30C. I'm soaring the last hour as I'm not far from 30C now! The last 3 night lows have been 25C (more like 26C, 80% of that overnight), 23C, and 24C. WUN nailed yesterday's details with exact high/low/full sun/RH, etc. from a forecast 4 days before on Fri. I noticed Toronto at 9:30 last night was still a insane 33C/90F Humidex 43C/110F.

I think most people would take warmth over arctic air. Link to comment Share on other sites More sharing options...

I think majority of people would rather have neither but would take extreme cold over extreme heat. And lol we get way lower than 40s for months. They could never even have a michigan Fall day let alone winter day. But these past few days are right on par with many Florida summer days. Thank goodness it was only 3-4 days.
