If you haven't noticed, it's humid — but some relief is on the way
Well, if you haven't noticed by now there is most definitely a connection between how humid it is and what the dewpoint is.
When the dewpoint is higher, there is more moisture in the air. (Compare that to relative humidity which really doesn't tell you anything about how muggy the air is)
So with dewpoints lately in the 70s, we've been sweating out even the not-so-hot days. The good news is that some drier air will be moving in later this week and into the weekend. This time dewpoints may drop into the 50s at times, making for some very nice, enjoyable weather.
We don't always get too many breaks like this so late into July, but it looks like the weekend will be a nice treat.
