Philadelphia is heading into a hot, mostly sunny Friday with temperatures pushing toward 90 degrees, followed by another warm day Saturday. The weekend’s best outdoor window arrives before showers and thunderstorms move in Sunday, bringing a chance of heavy downpours.
Friday Stays Hot And Mostly Dry
Friday will be mostly sunny, with a high near 90 and north winds between 0 and 5 mph. The rain chance is just 3%, though a few more clouds may arrive during the afternoon. Temperatures fall to around 71 Friday night under mostly clear skies, according to the National Weather Service.
Saturday Offers The Best Outdoor Window
Saturday will be sunny and warm, again reaching about 90 degrees, with a light northeast breeze. It is expected to be the driest and least humid day of the weekend, making it the better bet for parks, errands and outdoor plans. Saturday night will turn partly cloudy, with a low near 70.
Showers And Thunderstorms Return Sunday
Sunday brings a noticeable shift, with rain showers likely between 8 a.m. and 5 p.m. before showers and thunderstorms become more likely later in the day. The high should reach 86, with a 60% chance of precipitation and possible rainfall totals between a quarter-inch and half-inch. Sunday night remains unsettled, with an 80% chance of showers and thunderstorms and a low around 72.
Forecasters are watching the potential for heavy rain and isolated severe weather Sunday into Monday, although the exact timing and intensity remain uncertain. Downpours could create localized flooding, so residents should keep an eye on updated forecasts if they have travel, outdoor events or low-lying-area plans.
Next Week Brings More Summer Heat
Monday may start with a shower before a slight chance of afternoon thunderstorms, with a high near 89. Tuesday looks sunny and warmer, reaching about 88, while Wednesday should be sunny near 89 and Thursday may reach 90 with another chance of showers and thunderstorms.
Simple Heat Safety For Friday
With temperatures near 90, residents should drink water regularly, take breaks from direct sun and check on older adults, neighbors and pets. Philadelphia’s official heat guidance points residents to cooling centers, pools and spraygrounds during a Heat Health Emergency, and lists the city’s Heatline at 215-765-9040 for health and safety questions.
