Heat index contest

[Complete Turf Care]

After lots of rain this spring and early summer, we have been about 3 weeks without rain, and grass is dying.

Down here in the deep south, we have very high humidity which results in high dewpoints and very uncomfortable weather. What kind of 'heat index' do you have in your area? Below is a pic I snapped off of a web site a few days ago.

Ha Ha. Today we are close to or bettering records for the lowest high temp of the day in this area. Back to the mid-80's this coming week though.

Right now it is 61F and "it feels like 61F" with 96% humidity. There is foggy cloud mist in the air.

I don't know the actual humidity level, but last Friday was particularly brutal. Only 99 degrees but a "heat index" of 108. Unfortunately I had run out of work to do on a project in my a/c equipped ctl and sat on my open cab tractor in a pool of sweat all day.

We have had upper 90's all week and heat index has be 101 to 115 deg.
Humidity has ranged from 92% to 57% when the temp is >100.
Currently we are 91 with 65% humidity. HI is 108

Note to self. Initiate a "wind chill index contest" thread next January.

But Steve, it's a "dry" cold.
It actually does make a big difference. The humidity % (dew points) does really spoil both the hot & cold temps.

This was copied a few moments ago. Note the heat index is at 115 and the dewpoint temp is at 81* Then look at the chart below to find the comfort level of depoint at 81*

Last weekend was HI in the high 90's in Ohio and worse than normal, I work for international company & a German counterpart said they had ambient temps in the 105 range >80% humidity now that is miserable.

As far as Wind Chills, then Ohio will be in mix for sure, this spring we had -40s & set multiple records for lowest "high" temps when the HIGH doesn't get into + range is is cold...

107 now in central Oklahoma. Highest in the last 3 days was 109.

It's been so ho' here, a bunch of cows froze. That's right, froze to death. Wha' happened is the corn started popping right off the stalks, cows thought it was snow and got so cold they froze stiff.

This is NOT a contest I wish to win. Just Say'n. :confused3::laughing::laughing::laughing:

We have been pretty lucky this summer with only a few days in the upper 90's and I am sure the heat index was over 100. Seen much worse.

Later,
Dan

One of my pet peeves is when people overstate the humidity for dramatic effect. For example people often talk about 90 degrees with 90% humidity in the south. That would be a heat index of 122 and while it may very rarely happen it is NOT as common in the south as people like to say, and when it does happen people literally die.

What we typically see is more like 90 degrees with 60% humidity. No need to exaggerate, that's uncomfortable enough! Now people may be confused because it is often 90+ degrees and 90% humidity here during the same day, but not at the same time! A typical steamy day is 70/100 in the early morning with a high of 95/60 (which is still an HI of 110!). Looking at the history of my weather station, my highest recorded heat index value is 124. That would be 55% humidity at the highest temp I've seen (101 degrees). That's hot enough!

That's why I like to see people talk about heat index and not temp/humidity.

 

[farmer2009]

High today was 98. Dew point reached 82. Heat index on my weather station was 123. Highest I've ever seen on it was 124. That day was over 100 for a high.
Here's a picture of it. Look at daily records in bottom right corner.

Down here in the deep south, we have very high humidity which results in high dewpoints and very uncomfortable weather. What kind of 'heat index' do you have in your area?]

Depends on what you consider South. :laughing:

It's winter here and there was a wee bit of frost this morning. Right now it's 15c with 49% humidity.

We are normally so dry here that our "heat index" is not influenced by humidity. The temps you see on your thermometer is what you get.

However, that being said, this is, so far, the driest year of record for this part of the country. This morning at 6:30 our humidity was 12%.

Isn't that kind of low humidity a wildfire hazard?

 

[oosik]

Country Geek - I guess so - the forrest service folks say our wildfire "danger time" started a month earlier than normal this year. I know the extreme low humidity sure messes with my sinuses. It also seems to cause the breezes to put more crud into the air.

The good news is we had a very short burst of rain last night and this morning our humidity is back to normal - 52%.

I've experienced high humidity once - Houston in July - and I'll take the extreme temps and low humidity we get for a week or two over than anytime.

This year - first week of July - we saw the highest temps - 105 - ever recorded for this area. I spent two days camped in the bedroom with the window air conditioner.

It's 33 in Barrow, AK right now....

St. Louis today will be approx. 97 degrees with the "real feel" temp at 115 degrees.

That is hot but, not as hot as the Cardinals!!!

True, but not exactly fair because it was the middle of the night there when you posted this
