Residents of Philadelphia should brace for a cold week with temperatures dipping as low as 17°F tonight, according to the latest weather update from the National Weather Service. While the current conditions boast a relatively fair 20°F with a wind chill that makes it feel closer to 8°F, the city is expected to see an increase in cloud cover today, capping the high at a chilly 28°F. NWS Philadelphia reports winds from the northwest at 5 to 10 mph.

The weather takes a slightly warmer turn on Tuesday, with highs approaching a still brisk 31°F. It's a brief respite, as evening temperatures drop back down to around 23°F under mostly cloudy skies. Philadelphians should consider pulling out an extra blanket as the calm winds from the west settle in.

Looking ahead to Wednesday, the NWS forecasts some relief with temperatures rising to a more bearable 43°F during the day, thanks to partly sunny skies and a sustain southwest wind flow of 5 to 10 mph. The warming trend continues into Thursday, hinting at the possibility of a high near 52°F. However, rain is expected to move in by Thursday night, bringing breezy conditions and a high chance of precipitation at 90%.

The end of the week will not herald much of an improvement. Friday is slated to stay mostly cloudy with highs dipping again to around 46°F and a windy backdrop. The subsequent night brings partly cloudy skies with lows skirting freezing at 24°F. As the weekend arrives, Philadelphians will see mostly cloudy conditions, with a high nearing 39°F on Saturday and rain chances returning by Sunday to a tune of 30% probability.
