Winter Storm Ignacio.
Actually, The Weather Channel is calling it Iola, but I don't care for that name, and as you know, when I think something is misnamed--person, place, or thing--I will rechristen it. Nicole becomes Carolyn. Emily becomes Cindy. Quinn becomes Stanley. Jill becomes Kelsey. Brent becomes Brandon. Whatnot.
Snow arrives 10pm-midnight Friday. Surface temperatures will be right at or just above the freezing mark (32 for quick reference) throughout the storm, so it's going to be tricky predicting what type of precipitation will fall from place to place, hour to hour.
I am not punking out; I am just telling you what I'm up against.
Snow, then, beginning 10-12pm Friday and continuing through mid-morning Saturday, when it will mix briefly with sleet, then turn over to plain rain by noon, after which we'll see drizzle and flurries through mid-afternoon.
Total accumulation: I'm sticking with 3-4 inches for most of us (Berks, Lehigh, Bucks, Lancaster). Maybe an inch or two for Philly and South Jersey. Maybe a hair more--5 and three-quarters?--in Lebanon, Schuylkill, Northampton, Dauphin.
Travel impacts: Throughout Saturday morning, travel will be shitty over most of the region. Saturday afternoon and evening will be far better, then on Saturday night (after, say, 10 or 11pm) temperatures will fall back below freezing and slick spots will develop once again.
On Sunday night into Monday, we're looking at a clipper system moving through. It will accumulate only 2-3 inches generally, but (the way it looks now) the timing and overall balls-coldness (highs in the 20s with wind chills in the low teens--then falling throughout the day) will virtually guarantee a snow day.
Of course...
stay tuned for updates!
