Big change in our weather coming after a couple weeks of moderate temps and lower humidity. Hurricane Irene is already affecting the weather in NC, with the wind circulation carrying moist humid air off the ocean. I dressed for the 60s/low humidity we've been having lately and was all sweaty when I got to work. Latest forecast track shows that we are likely to take a pretty good hit from the storm by Saturday morning, but a lot could change between now and then.
