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.
Philadelphians could wake up to a new record-low temperature on Tuesday.
The cold-for-May snap hitting the region today — temperatures are about 15 degrees below normal — should continue overnight, with a low temperature of around 41 degrees expected, the National Weather Service says.
If the mercury drops any lower than that, Philadelphia would have a new record: The coldest temperature ever recorded on May 14 is 40 degrees, according to the weather service.
The weather service is calling that mark a “possible vulnerable record low.”
WASHINGTON – America set an off-the-charts heat record in 2012.
A brutal combination of a widespread drought and a mostly absent winter pushed the average annual U.S. temperature last year up to 55.32 degrees Fahrenheit, the government announced Tuesday. That’s a full degree warmer than the old record set in 1998.
Breaking temperature records by an entire degree is unprecedented, scientists say. Normally, records are broken by a tenth of a degree or so.
