This is due to an upper ridging patter that will drive warm moist air into our neighborhoods for a longer period of time. We could see heat index values reach the triple digits.

On Saturday, you could see some slight relief from the humidity as winds pick up. Gusts could exceed 30 mph Saturday evening. These strong winds create a wind chill effect when moisture is confined to yourself during elevated humid environments. However, with all the sunshine we are expected to see in the Saturday PM hours, it will still feel uncomfortable when heading out the door.
