'Quite the autumn feel' on Sunday, possibly even record low temps, NWS says

Looks like Mr. Autumn Man will have a grand time walking down Mass. Ave. on Sunday. The National Weather Service predicts the day will have "quite the autumn feel" and that not only will temperatures dip into the 30s by Sunday night, they could hit a record low - thanks in part to the drought, natch - maybe even warrant a frost advisory for areas closer to Boston than the Worcester hills.

Am concerned. Thinking an anomalous situation given dry conditions across the region coupled with the radiational cooling setup. Wonder whether guidance is capturing this rather well. A hunch that perhaps there`s an opportunity here to undercut guidance by a couple of degrees. Feel Sunday morning lows, if lower than initially thought, will weigh on confidence and forecast thinking going into Monday morning.
