Philly should see seasonal to slightly above temps Sunday evening, with partly cloudy skies and almost no chance of precip. They'll get a few inches of global warming tomorrow, but it'll be long gone by Sunday.
Here in NC, we'll have our second accumulating snow of 2018 with snow pretty much all day tomorrow. Add that to the several inches of amazingly light powder we got up in the Blue Ridge on New Year's Eve and we've gotten rather more snow than normal, and we're just halfway through January. We just set an all-time (since records were kept) for # of hours below 32 deg F at 210 hours ending about a week ago today. During that week and a half, we had two mornings in the single digits, one down to 4 deg F.
My long-time geologist buddy down in Houston, TX came home early today due to sleet and snow in the forecast and as I type this he's getting hammered with frozen precip. Second time in Houston this year--extremely rare according to him.
Like most trained observers, it drives me a little bit nuts when folks attribute individual weather events to climate change, even when the speaker (such as the POTUS) should know better! I do so here in a wholly tongue-in-cheek fashion, but it really gets under my skin.
