Philadelphia residents can look forward to a sunny and warm day today, with the National Weather Service predicting high temperatures nearing the upper 80s, a pleasant change for a mid-September day. Despite a slightly muggy start to the morning, with humidity hanging at 93%, the skies are expected to clear up, offering a dry and sunny Friday, according to NWS Philadelphia.

The city is set to experience a shift in wind direction, transitioning from west to a gentle northerly breeze in the morning which should bring a semblance of relief, tonight the forecasted low will be around 60 degrees, and while the wind picks up slightly to 10 mph from the northeast the city sleeps under partly cloudy skies; that's the word from the weather experts over at NWS. As we ease into the weekend, Saturday will continue the trend of mostly sunny conditions, presenting an ideal setting for outdoor plans with a high of 77, though an east wind around 5 mph.

Philadelphia can expect partly sunny skies on Sunday with a high near 74 degrees, offering mild conditions for outdoor plans. By evening, skies will remain partly cloudy as temperatures drop to around 57 degrees, providing a cooler, comfortable night.

Looking ahead, the start of the workweek maintains the pattern of mostly sunny days; Monday's high is expected to be around the upper 70s with partly cloudy night skies and a low of 63, it's when Tuesday rolls in that we might see a little change, as there is a 30% chance of rain showers after 2 p.m., though the day remains mostly sunny with highs in the lower 80s, the possibility of rainfall offers a brief intermission to the stretch of clear skies we've been enjoying according to NWS Philadelphia. Wednesday will take us back to mostly sunny conditions, though the night turns mostly cloudy with a low of 62, finishing the week with a comfortable 75-degree high on Thursday under partly sunny flags.
