You're older than me and if you don't know what sun angle means by now, I don't know what to tell you. Not being disrespectful.
Accu weather/Weather Underground have me at 27F. Could they be off by a degree or so...sure?
I would go lower during daytime. 27F today and light drizzle and nothing. Took a stroll and everything was wet.
People don't want to admit it but the sun angle is kicking in...27F currently, no ice.
Just looking at the radar, Central Del and a little further N will be alright but SE PA looks very iffy and the burbs may get whiffed and have a cloudy day w/temps in the 20s...
I don't know exactly how many years all the local channels have been doing their winter outlook but combined they can't be more than 20% accurate. And when I say accurate I mean "pretty close"....
