You must have had a really looong wire (like 200 miles) or an acute inability to accurately decipher day from night.
As I'm sure you know, Sam, skywave reception at midday in mid-winter, though uncommon, is not all that rare. At that time of year, you will often see reports similar to mine on MW DX lists and forums. Back in that day, all three of New York City's (then) Class IA AMs plus Class IB WNEW (AM) and Class II WHN were listenable at the south end of Troy all day every day. (OK, at night, WHN often took it on the chops from CHUM.) During daylight hours, those stations were coming in 150+ miles away via groundwave, although, every now and then, there would be brief fades when the daytime skywave would duke it out with the groundwave. Same for CBF and CBM, which were even further away (and CBM was (slightly) directional--AWAY from the US). Despite the great conductivity in much of Jersey and the very good conductivity in most of the Hudson Valley, WCAU's groundwave did not make it the extra hundred miles to Troy (relative to the New York stations). My midday reception of WCAU was, indeed, daytime skywave. I was not dreaming then and, even after all the years between then and now, my recollection is accurate.
