The National Weather Service is again calling for an excessively hot day today, with temperatures for the Pottstown area expected to reach 96 but feel like 108 thanks to the high humidity. There is a 40 percent chance of scattered showers or thunderstorms this afternoon with more rain expected tonight.
An Excessive Heat Warning is in effect for the area through 8 p.m. tonight. Montgomery and Chester counties have issued Code Red hot weather advisories each day of this week through Saturday from noon until 8 p.m., the hottest parts of the day. Area residents who are without air conditioning should seek shelter in a cool place and pets and children should not be left in hot cars, the weather service and counties advised.
“A cold front from the Northwest is expected to arrive on Saturday night and it should bring an end to the heat wave,” the weather service wrote in its latest advisory.
The Department of Environmental Protection and its regional air quality partnerships have forecast an orange air quality action day for ozone on Thursday, July 18, for Bucks, Chester, Delaware, Montgomery and Philadelphia counties.
On air quality action days, young children, the elderly and those with respiratory problems, such as asthma, emphysema and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.
