Discussion…
•A ridge that will be entrenched across the Eastern US will bring a multi-day period of hot temperatures to the state from today through next weekend. Daily chances of showers/t’storms across the state may temper conditions for some areas at times. While heat index values will be elevated on a daily basis during this period, oppressive conditions are not expected. Thus, while this period will be considered a heat wave, it will be temperature based and not heat index/humidity based.
