Discussion
Yesterday featured high temperatures near the 100 degree mark in many locations along the DC-to-Philly-to-NYC corridor with a record-breaking 99 degrees recorded at Philly International Airport (PHL). The bad news with respect to this current hot spell is that the peak may actually come later today with numerous 100 degree readings on the table in the I-95 corridor compared to Monday. The good news is that much relief is in sight by the end of the work week on Friday and next week looks much closer-to-normal in terms of overall temperatures.
The last time Philadelphia officially reached 100 degrees at the International Airport (PHL) was on July 18th, 2012…and it could happen again later today. The very strong ridge of high pressure to our north will weaken later in the week and also shift southward. As a result, the heat will not be as intense here on Wednesday and there will be a chance of PM showers and thunderstorms. Temperatures drop even further on Thursday as a back door cool front approaches the region and the chance of showers and thunderstorms will increase. Any thunderstorm that forms on both Wednesday and Thursday can be strong-to-severe. This back door cool front could actually bring much relief by Friday as an ocean flow of air could develop and end the work week on a cool note.
