For the first time this season, we're talking about two four-letter words: cold and snow.
Come Friday, the first snowflakes of the season could be falling before a bitter cold snap takes hold across the Philadelphia region.
A mostly dry pattern is in place to start the week. The only chance for any precipitation is some scattered rain showers that are expected Tuesday morning, with the best chance in Delaware and South Jersey and diminishing the further north you get.
Monday through Thursday, highs are expected to mostly be in the upper 50s to low 60s with lows mostly in the 30s overnight. Be ready to bundle up for the morning commute.
The big change comes on Thursday night as a cold front roars in. We will have feels-like temps in Philadelphia go from the mid to upper 50's on Thursday afternoon to the teens by Saturday morning.
Most neighborhoods are expected to get rain. There could be a chance of snow overnight Friday, if temperatures drop quickly enough along the cold front. Expect blustery winds Friday morning.
There likely won’t be any accumulating snow. Also, look out for the potential of slippery spots where water on the ground freezes.
Frigid conditions then grip the region through the weekend with highs in Philadelphia only getting in the low 40's Saturday and mid to upper 40's Sunday. Below-freezing lows are expected both Saturday and Sunday mornings.
Even if you don’t get any snow this week, there is a chance for snowfall next week as we track another system. It's too early, however, to have a clear vision of what precipitation, if any, will fall.
One way or another, winter is coming, so make sure you get your home, car and wardrobe ready now.
