The history of temperature measurement in America is to constantly produce cooler readings as technology has improved and standards revised, and then have people complain about adjustments and claim it was hotter in the past. Considering the ASOS is installed at 1,203 feet ASL and the buildings in which the downtown temperatures were taken many decades ago were from about 720 to 750 feet, taken on a rooftop with only passive solar shielding (LiG thermometer housed in a shelter, and no fan aspiration), one can only wonder what the temperature would be today. Absolutely ridiculous that mean temperatures over the past 24 months have been on par with the hottest years in the threaded record.

Anyways, y'inz stay cool out there this week. Already up to 82F as of 9:51 a.m., with a heat index of 84F. 90+ looks like a foregone conclusion today, unless a storm forms by noon and sits over us the rest of the day.

No doubt non standardized & less accurate equipment combined with varying procedures and changes in sensor location make over analyzing past data older than 30 years for comparison to today's readings a fool's errand. It would be interesting if some of those older technologies were run synchronously with the new technology to see the differences and provide solid data that would be hard to refute. In any case, the trend over the last 30 years is higher temperatures, no way to sugar coat that. 

For our sakes, let's hope the current period is perhaps a combination of constructively interfering factors all adding to more pronounced warming in the overall trend and not the beginning of the last chance to avoid any tipping points.

Anyone caught in those storms out there today? Plenty of fuel, NWS makes mention of strong winds as the biggest hazard, curious how that is materializing in the strongest cells.

Not raining imby but wind has been gusting hard. Text of the warning would indicate that wind damage is occurring.

That was an absolute doozy. Hampton and trees down everywhere. Was under  gas station on route 8 as it rolled through and can believe 70mph gusts

A little bit south and it was seemingly all outflow. Lots of branches down from the wind but hardly any rain and a ~25 degree temp drop. Was worried the dog wouldn’t get a walk this afternoon but this is fantastic weather for that.

This is not ideal at all to have 60k outages that will likely extend a bit into at least tomorrow when we hit the mid 90’s 

Wow, I didn’t realize it was that many! At least the storms brought in some temporary relief. Still not ideal for open windows with the high humidity.

We must’ve dodged a bullet locally. Nothing more than some small branches down. Much needed rainfall - doubled my monthly total.

Wonder if we have a repeat tomorrow. NWS is expecting temperatures as warm, if not warmer, with heights continuing to rise. Might be less coverage with a stronger ridge overhead tomorrow, I would guess?

I don’t know, we seem to be one of the few places where a stronger ridge does not mean less rain, lol.  Ron Smiley just said storms should be firing by 2pm.  If they do hit then no way it’s as warm as expected.

From a station serving Steubenville, Ohio & northern West Virginia, but sharing as I thought this was a nice regional map of high temperatures from yesterday. Impressed by the 89 in Johnstown - the airport is at close to 2300 feet, I believe.

Lagging behind yesterday’s temps by 2 degrees.  Clear most locations except KPIT, lol.  They have a knack.

Humidity is up from yesterday and it’s already that filtered hazy sunshine imby, so maybe not just at the airport.

It’s funny how much you complain about temperatures but absolutely lose your mind about anything I say about snow.

 

I don’t want to hear it once this winter from you.

Honestly, I won’t respond to a certain very sensitive poster, but was there a complaint in my post?  I stated a fact and then made an observation.  I’m not bothered by it at all.  Humidity is definitely the culprit from the rain yesterday.

This certainly isn’t going to ruin my day like snow does for someone, but it’s just interesting.  90 looks locked today, just a question of how high it goes.

Also, I wonder if that hazy layer will actually help keep storms down today?  Maybe without the most direct sun it keeps it a bit more stable.

Admit it, you’re a little sad that the insane heat probably won’t be materializing this time. I was, until the storms knocked out tens of thousands of people’s power yesterday and realized that it’s pure luck that it wasn’t me. Now I could take or leave the extreme stuff.

These storms developing don’t seem to have much forward motion to them. Seems like they’ll drop a lot of rain wherever they do end up hitting.

Case in point, the storm currently sitting over MGW airport dropped over an inch of rain in less than a half hour, with a gust to 54mph.

This I was a little disappointed since it's historical and all, but once your power goes out your priorities change.

Sure, they were hyping all time June records.  It’s be neat to get that, but realistically I knew that was unlikely.  So, there isn’t any complaint here, lol.  Might still be able to sneak a 95 or 96 later in the week.  Though, if we had that higher heat we likely wouldn’t be having the storms.

Seems they are coming from the other direction today.

High was at least 92 at KPIT. Probably 93 or 94, based on 5 minute data. Multiple observations of 34C/93F, but that could be between 33.5C and 34.4C [92.3-93.9F].

Looks like another 94. That’s 2 in a row. We haven’t had 3 days in a row of 94+ in any month since 1995.
