Philadelphia residents can expect a range of weather conditions this week, starting with patchy fog and ending with a chance of rain and snow. Earlier today, visibility was down to 0.50 miles with humidity lingering high at 93%. These foggy conditions are predicted to clear up by mid-morning, making way for mostly cloudy skies and a calm southwest breeze, according to a detailed forecast from the National Weather Service (NWS) Philadelphia.

The NWS Philadelphia has advised that patchy fog will dissipate to give way to a mostly cloudy day with a high near 46 degrees. Winds are expected to stay calm before turning southwest at around 5 mph. To navigate calmly through the sights of Philly, residents should look forward to clearer skies later in the day. The transition from fog to clearer skies may just slowly take place, setting a calm tone for the day.

Tonight, the clouds are sticking around with a low forecasted around 36 degrees. Moving into Wednesday, there's a 50% chance of light rain with less than a tenth of an inch of precipitation possible. As we approach Wednesday night, the chance of rain drops to 30% before midnight. Overall, Philadelphians can prepare for mild, yet cloud-filled days ahead.

Heading into Thursday, the potential for rain seems to persistently cling, with a 30% chance starting in the afternoon. Rain is more likely on Thursday night, with the chance of precipitation jumping to 60%. Friday's outlook calls for rain, so it seems inevitable to escape its presence — with a 90% certainty, no less. As the weekend arrives, we might witness a slight reprieve, but keep those umbrellas on hand for Saturday night — there’s going to be a chance of rain and snow after 1 am, and it sticks around through Sunday.
