2006-07, another weak Nino, was pretty wretched after a chilly start during the first week of December. Widespread warmth that had people in early January in Boston noting that trees were blossoming and folks in Ohio complaining about insects.
The guy from NM was hitting the '06-'07 analog pretty hard throughout the fall in Chuck's ENSO thread on the main forum. That terrible month + from early-Dec through mid-Jan was warmer than this stretch has been, but the pattern flipped around 1/17 when an EPO ridge built north through Alaska. That ridge started showing up about 12-14 days prior to onset on the ensembles.
I know that winter isn't remembered fondly by the metro area crew, but my yard hit snow climo with the latest of late saves: the VD storm that dropped 3" of snow here followed by 3" of sleet, a 6" dump on 2/25, another WSW event in early March (a rain to snow event) and another 6" on 3/17 after 3 days of temps in the mid- to upper 70's. The whole month of February was great for consistent cold and storm chances. No reason to think we couldn't do it again.
