hmm.. this is odd. For no reason at all, IAH fell from 95 (Heat index of 108) down to 93 (Heat index of 102) during the last hour.

[Yankeegirl]

This weather is just plain nasty.... When is winter going to get here????

[Extremeweatherguy]

3pm airport reports from around SE Texas...

IAH = 98˚
Tomball = 98˚
Conroe = 96˚
Hobby = 98˚
Huntsville = 99˚
College Station = 96˚
Galveston = 96˚
Beaumont = 99˚
Lufkin = 98˚

Based on the current 3pm readings, I have a feeling that many sites will be breaking the century mark this afternoon!

[Sean in New Orleans]

We already have broken the 100F mark in and around New Orleans and all over Louisiana for that matter. It is brutally hot....

It feels like an OVEN outside!!! 101 officially, my vehicle is showing 105 though and I tend to believe it!

[southerngale]

It just officially hit 100° at the airport (BPT) The heat index is currently 110° there.

We go from constant rain to unbearable heat. Where's the nice weather? lol

KMOB (Mobile) recorded 101*F, which sets a new record for August 11. No reason to think that it will be any different along the north-central Gulf coast until the latter part of the next week.

[Extremeweatherguy]

Current noon-time temp. at IAH = 98˚
Current noon-time Heat Index at IAH = 112˚

If I had to make a bet, I would say that IAH hits 100˚ for sure today..may be even 101 or 102!

[Extremeweatherguy]

1pm temp. at IAH = 99˚
1pm Heat Index at IAH = 112˚

It is HOT!

We're on the major compression side of the upper ridge

Would someone please tell me what the "major compression side" means?

[Sean in New Orleans]

Still 97° right now... geesh!

yeah, in New Orleans the actual temperature is 97F, still, at 7:00PM....I think we'll be lucky to get below 85F, but, we are experiencing lower dewpoints in SE LA, so, it's possible we'll see the 70's....but, my air is having trouble keeping up with the heat...

[jasons2k]

Readings at my house:
High yesterday: 103F
Low this AM: 80F
High today: 105F

Today was our hottest day since we moved here in May, 2005!

[cajungal]

Today we hit a record high of 107 in my town. That is the hottest it has ever been EVER. Beating a all time high of 101 set in 1986.

The 97° I mentioned above was the actual temp at the time as well, officially, at the airport. Too hot for that time, huh?
