The National Weather Service on Thursday issued a heat advisory for Berks County and the rest of southeastern Pennsylvania that starts at 11 a.m. and runs nine hours until 8 p.m.
The heat with humidity is expected to result in heat index values from 100 to 103 degrees, the office in Mount Holly, N.J., said.
The advisory also reads: “Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.”
The high Tuesday at Reading Regional Airport was 92 degrees, and the high Wednesday was 94 degrees. The Reading Eagle report of 95 degrees was incorrect.
Berks was not in a heat advisory Tuesday or Wednesday, as was the rest of southeastern Pennsylvania, mainly because dew points were in the 60s, keeping the heat index below triple digits.
That changed Thursday as the dew points climbed into the 70s.
The chance of storms is courtesy of an approaching cool front, which is only cool in comparison to the temperatures ahead of it.
Sunday’s weather should at least challenge the date record of 96 degrees.
For Sunday and Monday, low temperature records might also be in jeopardy. The mildest lows on record for the dates are each 78 degrees.
At the airport Thursday, the temperature had already reached 87 degrees at 10 a.m.
