How cold will it get in Philadelphia? Prep for Arctic wind chills
Snow isn't the primary impact of this storm, the big weather story is what comes after.
Very cold Arctic air will sweep in with gusts between 40 and 55 mph, creating travel delays and scattered power outages.
The temperatures will also plummet to the low and mid-30s as the coldest air this season arrives later today, tonight and tomorrow. The wind chills will hover in the teens and 20s through tonight.
If you're headed to the lighting of Philadelphia's holiday tree tonight, definitely bundle up and wear a hat and gloves, maybe a scarf. It will feel like 23 when the pre-lighting festivities start at 6 p.m. - the lighting happens at 7 p.m.
By Friday, sunshine and wind will return, but the warm air will not. We will end our week very cold, with highs in the mid-30s and a wind chill in the 20s.
The weekend will be warmer, less windy and partly to mostly sunny, with highs in the 40s on Saturday and 50s on Sunday.
That above-average warmth sticks around next week, with highs touching the low 60s on Tuesday. Snow isn't in the forecast next week with such mild days, but rain is possible both Monday and Wednesday.
Winter's first official day is just 16 days away on Dec. 21. The Winter Solstice takes place in Philadelphia at 4:19 a.m. that day. It is the time each year when all places on the planet should receive equal hours of daylight and darkness. After Dec. 21, we will see more hours of sunlight each day.
It does turn a bit more seasonable, with temperatures near 50 for the Eagles' potential playoff-clinching game Sunday. It will be partly cloudy and breezy. No rain or snow is expected, and the winds will be southwest at 10-15 mph.
A return to the 50s and even a 60-degree day are possible next week.
