Time to post a page of diff. eq.? :-)
Back on topic: I checked the Boston, MA, NWS forecast page this morning. (Have friends in area.) Looks like “no fun” if it pans out. The cold to follow is going to be “unpleasant” if there are widespread & lasting power outages.
Still, I would guess this will not be as bad as the 2009 mid-South ice storm. We had folks just up the road from us, still on generator power, 3 weeks later. A few nights were single digit cold.
I'm glad those days are behind me.
Once was enough.
