(11:30PM Sunday - 6/19/22) Another ridge will quickly build and move eastward through the Central and Eastern US, during the early and middle portion of this upcoming week. As this ridge moves through, along with it will come a push of hot conditions, which will expand and take up residence across the state and region for a several day period. When comparing to the the recent heat wave of June 12-17th across the state, peak humidity and heat index values will be lower this time around.
