Gov. Baker made his first Bunker appearance shortly after noon, wearing, a, um, a suit? Yes, a suit.

The T will operate normally through the end of the day, then shut for Tuesday. A driving ban will go into effect at midnight. Baker said stay off the roads unless you're "essential personnel" (and that includes people who work at supermarkets and gas stations and, of course, the news media). Then he said stay off the roads. Oh, and by the way, stay off the roads.

BOSTON UPDATE: City snow emergency goes into effect at 6 p.m., so move your car off emergency routes by 8 or lose them. Schools shut both Tuesday and Wednesday. List of parking lots/garages with discounts for residents.
