The forecast shows warm air surging into southeastern Pennsylvania for the workweek, with high temperatures in the 80s, and possibly reaching 90 degrees in some areas. Daily high temperature records are in jeopardy, especially on Wednesday when the peak of the heat is expected to coincide with a record of 88 degrees.

Why it matters

The warm weather and potential for record-breaking heat comes as the Philadelphia area is already behind on precipitation for the year, raising concerns about drought conditions if the dry spell continues.

The details

Forecasters say the warm temperatures will gradually build through the week, with upper 80s expected by Wednesday and Thursday. While 90 degrees is not out of the question, the lowest hanging fruit for a new record is the 88-degree mark on Wednesday. The warm and dry conditions follow a year where the Philadelphia region has recorded about 3 inches less rainfall than normal so far.

  • The warm weather is expected to last from Monday through Thursday, with gradual cooling forecast for the Friday through Sunday period.
