Official report shows ending at monthly average temp of 75.7 (0.1 degree above 'normal') with 6.26" (2.20" above 'normal') precip.

Only 4 days above 90 degrees.  I went back at looked at 2016 and that showed 18 days above 90.  Each of the previous 3 years ('13, '14 and 15) all show at least 10 days above 90.

Kind of strikes me as weird, but the high for 7/3 appears to have been around 9AM at 82 degrees.  That was during a brief break in clouds as I recall.  Since then, it's been hovering around the upper 70s.

Hit an all time record high dewpoint of 80.8F (27.1C) on my Davis VP2 today with the SHT31 (aspirated). Local ASOS (KHSV) peaked with a dewpoint of 79F (26.1C) around the same time. We had a brief rain shower lasting ~10 mins then the sun came out immediately after and began efficiently evaporating water since it was near solar noon (and causing a quick spike in evapotranspiration from vegetation). The ground is very saturated here (northern AL, USA) since we've had several days of afternoon and evening thunderstorms.

Notice the quick increase in dewpoint as temperature increases when the sun came out then the decrease as the moisture was mixed out with "drier" air in the boundary layer. I put drier in quotes because the dewpoint has been very high here the past few days... averaging ~70-75 dewpoints most afternoons. Also interesting is how high the apparent temperature and heat index is (mid-90s) even with a temperature only in the low 80s. Goes to show how dewpoint plays a significant role in how "comfortable" the air feels; in this case, very oppressive! :shock:

I was in D.C. two weeks ago and one day the dew was mid 70's, we were outside, I was miserable. I grew up in that stuff but haven't been in it in 17 years or so. Living in a dry climate such as mine for the last 28 years made it even more insulting.

The dewpoint (and even RH) has been so consistently high with all this rain that most shaded areas (like my driveway) don't even dry off completely before it rains again the next day :lol: Imagine getting out of a pool to dry off or trying to air dry clothes with dewpoints in the 70s.... it's nearly impossible :-)

High dewpoints basically normal here in the summer, but I LOVE dry heat. Had my first experience with that 2 summers ago in the Plains. It was ~105F with dewpoints in the 30s I believe... man that was nice. The last time I had felt a temp of ~105F, the dewpoint was in the 60s :shock:

Out of curiosity, what's the highest dewpoint you've recorded at your place in AZ?

During the monsoon, which is just now starting, ours dews will eventually get into the low/mid 60's and pretty much stay until we dry in latter Sept. With that, the highest I remember here was 74F. That's rarefied air for my neck of the woods.

Wow, I can imagine so. The average dewpoint at my place over the past 7 days is 73... :-|

I should have also stated that when we do get into the 70's, it's always at night after the BL becomes seasonably wet and have had several good rains. Thank goodness we don't get those dews in the day. =;

Couple of weeks ago, pool water was getting low and it was almost as clear as tap water.  I was thinking of adding some to it though.

This morning it's back to overflowing and has taken on some cloudiness due to 'stuff'.  Don't ever let anyone tell you rainwater is clean and fresh.

It has been a quite enjoyable spring and summer in Minneapolis. Decent temps. First half of june above average-last half below. Warm days. Cool nights and ok with precipitation.

Yesterday and today are a humid mess. But it will end today.

Highest temp so far is 91.  We will have a higher one later this year. But if this trend continues-chances are about 20% we will hit 95.

Last week was very nice here too, most of the time partly cloudy, with daily max around 25C (77F) and min at night around 12C (53F), maybe it could rain a bit to freshen up the air, but at least it is not too hot.

It has been quite an average July here, without any heat extremes.
According to the "newer" 1981-2010 longterm averages, (the German Weather Service still uses the "old" 1961-1990 averages) this month would be currently one degree Celsius below average.
The hottest temperature so far was 27.2C (81F) but most days were actually hovering between 17 and 21C (63-70F).

Best Regards

Georg

Umm, it's July, right?  Mid-July?  So, why are they making a fuss over 4-5 days in the mid 90s with HI in the low 100 range?  Isn't that like ..... uummm  ....  normal?

Yeah, it may venture to a 100 or so this week here for the first time this summer.

Despite it being climatologically normal, it hasn't been quite this warm yet this year so they need to make sure everyone freaks out for no reason  :lol:

Well, by comparison the next few days definitely will not be comfortable, but I get out early, do what I have to, then come in by noon or so.  I don't like that kind of heat at all, but as I said, this IS July.  I just hope it doesn't extend beyond a few days.  We've got about 8 weeks, maybe 10 before we can expect things to begin to cool off and I sure don't want high 90s for that long.

Last several days have been several degrees below normal for me, up to 10 F, but starting Thursday, Highs will be several above normal, with highs at least 95, and the weekend my touch 100. Before the cool down, Heat Index was 115F for a time during a couple of afternoons. The hottest day overall, there was no heat advisory... I think this time, there may be heat warnings issued. All we can hope for is the A/C making it thru the period, which will last at least 5 or 6 days.

Heat advisory out for much of the central part of the U. S.  On Thursday in central Oklahoma, including my station as pictured, a number of places got to 100 for the first time this summer.  Dew points are in the low to mid 70s.  A temporary break in the heat at my location is forecast to come on Monday and Tuesday with a good chance of rain.   If it rains enough then,  it will keep the grass green and lawn mowers running.

Floating thermometer in the 1,200 gallon pool shows 95.  Not exactly refreshing, but at least you can rinse the sweat off.

If you get a chance all, pull up the mesonet and look at Raleigh NC airport, and Fayetteville, NC airport. 99 F currently. Everyone else on the board that is close to legit is in the low to mid 90s! I call BS.

Yep, the heat here in town is pretty brutal. Not to mention I live in a depression near a creek so my humidity values are typically higher than what the airport reports.
