Philadelphia residents can expect a brief brush with showers and thunderstorms this morning before conditions clear up, paving the way for a sunny day with highs soaring to the mid-80s, according to the National Weather Service. The calm before the storm may be literal today; albeit a 20 percent chance of precipitation this morning, skies are expected to brighten as the day progresses. A north wind will shift westerly, ensuring that the mild conditions won't stick around for too long.

This evening's forecast points to mostly clear skies with a steady temperature in the low 60s. Winds, maintaining a mild pace from the west, will wind down to a more gentle breeze later in the evening. Come Saturday, Philadelphians should look forward to sunshine and warmth, with the day peaking at a toasty 84 degrees. However, a shift in wind direction could stir up some instability, leading to another slight chance of showers and thunderstorms rolling in after 2 AM, sticking to that modest 20 percent likelihood of rain.

The National Weather Service has detailed a similar pattern for Sunday, with conditions mostly sunny and highs in the mid-80s. Nonetheless, there remains a slight chance for showers and thunderstorms, both before 8 AM and after the afternoon hours. South winds will continue to blow at a gentle 5 mph, not enough to deter any barbecues or outdoor plans but enough to acknowledge the presence of a slight uncertainty.

As Memorial Day approaches, the forecast suggests an increase in storm activity. Monday could bring heavier rain, with showers and potentially strong thunderstorms becoming more likely after 2 PM. The chance for precipitation jumps to 70%, and some of this downfall could result in significant rainfall. The night may also be a wet one, with showers and possible storms before 2 AM, and again a possibility after. The remainder of the upcoming week is characteristic of late spring's indecision—days of sunshine interspersed with sporadic chances of rain showers.
