Today's weather will be near flawless. Even though we will heat into the low 90s. The humidity will be low enough so that it will be comfortable.

Temps by Friday will be in the low 100s with dew points near 70. This will be a dangerously hot and muggy air mass that will keep us from being outdoors any more than needed as it hangs around keeping temps in the 100-105 range through the weekend. The heat index will be close to 110.

Dew point values (one way of determining how much moisture has evaporated into the air) this time of year are routinely in the low 60s which makes it feel somewhat muggy out. Today dew points are in the 40s and 50s indicating a much drier air mass than usual.
