I dont understand the SEVERE WEATHER WARNINGS ...C'mon just say it's getting Chilly!
They consider 30-40 degrees a 'freeze watch'
I was born and raised in Staten Island, NY, and I dont remember the schools closing for icy roads.
Here in Charlotte...they close schools and businesses if the roads get 'icy'.
I remember it snowed at least 12-16inches of snow in NY...and the schools would never close.
Thank God I work from home.

I had to walk to school...it was like 5-6 blocks away.
The cheez bus was for students who live more than 1mile away
Living in Texas I can help with this. :-) Us southerners, even those farther south on the east coast than NY don't generally get real freezing weather. Most of us don't even get snow. You should see the dazed looks on our kids faces when they see snow on TV at age 3 or 4. White dirt?
Anyway, our cities aren't built to function in nearly sub-zero conditions. We don't have chains for our tires. Heck, we don't even know how to drive in sleet. It's a lot safer for us to stay off the roads when the red stuff in the little glass tube starts to drop.
So, go easy on us. We'll do anything for a "day off." :-)
