Our NEXT Weather team is tracking dangerous heat as we begin three days with temperatures in the 90s and heat indices in the low 100s. Monday's heat index may max out around 100, while we are expecting 102-104 on Tuesday and Wednesday. When temperatures climb this high, it can be dangerous for anyone without adequate ways to stay cool and hydrated. The NEXT Weather Team has issued a NEXT Weather Alert during this heat wave to keep you aware of the dangerous heat. More in bio. #PAwx #Philadelphia #NEXTWeather
