Water-vapor imagery this morning shows a longwave trough over the eastern U.S., while a ridge resides over the West with a series of disturbances moving east across the Canadian Rockies. The mid- to upper-level low over IN this morning and associated cold pocket yielded a November record low 500-mb temperature (-40.9 deg C) sampled by the 12 UTC ILX raob at Lincoln, IL. This upper feature will move east to NY/PA late tonight. A cold front over New England this morning will push east of the coast later this afternoon. A couple of lightning flashes may accompany weak convection from eastern MA into Maine before ceasing later today. Farther south, seasonably cool/dry air will continue pushing into the Gulf.
