I'm leaving things messy this year. I'll mulch or rake the leaves on the grass, but I'm leaving the leaves in my mulch beds. Good habitat for overwintering insects. Hopefully will also save me a bunch of money on lawn bags.
Brief cold air shot next week is gaining some oomph over the last day or two of runs. Verbatim 12z gfs says should be enough for freezes everywhere except probably DCA. Highs in the 40s as well.
