yeah living in that area for years, i am doubting the ice forecast - this isn't the right set up for it. Up in the mountains a different story like you say.
well so far DCA hasn't been below freezing since before Christmas, and even up here around 400 ft in Tenleytown we have just barely grazed the freezing point. Hopefully the air mass in place in a couple days can push the temps down a bit.
a 970mb massive low tracking in the same location would be in the same ballpark (I think the lowest pressures in '78 were in the mid 950s). Could trend stronger, but it's obviously a ways out.
51/40 for the last day of 2023 at DCA. Just kinda continues the theme of just... mild. Not blowtorch, but not cold. Hopefully we get some snow here in the next few weeks (starting here in less than 7 days!).
