I’m sure you have enjoyed the lower humidity this afternoon. We’re sitting in a great spot between an area of low pressure to the east, and a dominant high across the southwest.

The low across the northeast is responsible for the lower humidity. Air around the low flows counter clockwise, and that’s why our winds have been more northerly. That northerly wind has helped to usher in dry air from the north.
Unfortunately, this pattern won’t last, and the heat and humidity will push back in from the southwest for Friday and Saturday. Enjoy this airmass while we have it!
