Sunday promises to be a much quieter and much more comfortable day.
It’ll start muggy but humidity levels will slowly and gradually decrease throughout the day. Low temperatures Sunday night will fall into the 60’s in Philly for the first time in nearly two weeks.
Monday looks like a nice day with relatively comfortable humidity and just a slight storm chance.
Wednesday looks to be the most active day of the week as a cold front drops into the area. A flash flooding threat is not expected for Wednesday.
The frontal passage will open the door to much drier air with dewpoints, potentially falling into the very welcomed 50’s on Thursday.
The end of the workweek looks dry and quiet.
