FIRST REPORT, 7:14 PM: Beautiful sunset tonight – thanks to RS for the view from Constellation Park. The sky’s mostly clear and the temperature’s dropping, so it’ll be a cold morning, but you might be wondering, when’s the next chance of snow? The latest “forecast discussion” from the National Weather Service suggests Thursday afternoon/evening, and maybe toward the end of the weekend, though that’s far-enough out that it’s still “super-speculative.” No official alerts for any of this right now, though.
8:43 PM: Thanks to the commenter who pointed out that the NWS has just issued a Winter Storm Watch. Excerpt:
