5:30 pm Update: This afternoon's model runs confirm the earlier trend away from late Sunday/early Monday precipitation, although it can't be completely ruled out.
The computer models have continued to disagree overnight over the prospects of snow Sunday night/Monday morning, but each of the major U.S. models has remained consistent with its own previous snow vs. no-snow forecasts. The lack of consistency between models at the 36-hour range weakens the pro-precipitation case, however, so the chances of a wintry event are diminishing. The main effect on the Inauguration of such an event would be to reduce temperatures on Tuesday, increasing the likelihood that readings would remain below freezing.
