I was going to drive from Newburgh, NY to Nazareth, Pa. this am. Going along 84 down thru Bushkill, stroudsburg area and south. Thinking wice now, 19 deg here with heavy snow and up to .5 of ice later.

Yeah all the schools in Allentown are closed here ..they made the mistake of plowing the roads BEFORE the ice started falling. Which turned them into skating rinks and you have absolutely no traction now...

Not a good move to plow that snow off. Commute will be dangerous. Ground temps are cold too. This stuff will freeze up quick.

Not saying it's the case with this storm, because it's a totally different animal, but if you don't plow the snow/sleet off the roads, you run the risk of a VD07 repeat. Even the roads that remained open had a 1-2 inch ice pack on them that took days to completely melt off. Anyway, temps are rising fast now as I'm up to 24.9 now. Still a bit to go to get above 32, but they're on the move.

Center city PHL is a mess. One giant glazed donut. Had to drive GF to the airport and 95 was barely treated. Side streets are bascially 2 inches of chopped up snow with a .1 inch coating of frozen rain on top. Temp slowly nosing above 32 but it is in no apparent rush- that is for sure.

It's a mess out there. Wait till it rains for a few hours if you really have to go anywhere and don't have a subaru monster. Everyhbody besides me was slippin in the city.

The difference is, tomorrow will be near 40 degrees.

For what its worth, looking back at the 12z GFS/NAM from yesterday, here are the temps. they forecasted at PTW. GFS was actually too cold around here and the NAM more in line. While the PTW airport is reading 32 now (at 6am) I think its ASOS is messed up (it reported a gust over 100mph a little earlier) but in my neck of the woods, about 5 miles from the airport its currently about 30 degrees....

Philly is running colder than both the NAM and GFS from 0z but the NAM is the colder of the two for 7 AM (34 NAM, 35 GFS on the raw data). Probably will be 32 at PHL at 7 AM.
