She drives me crazy

"She Drives Me Crazy." - Part 2
-Fine Young Cannibals, 1989
  • La Nina: The main source of your weather frustration due to inconsistency of patterns this season. Why? Lack of a strong signal from multiple factors (Weak polar air, limited moisture transport from oceans, reduced snow cover) produces the type of erratic outcomes we have seen in 2016-17.
  • Are we done? Probably not. Potential is rising for a resurgent period of significantly colder air in the eastern U.S. from March 3 through 15. Several clippers in this period would have favorable conditions to produce snowfall, including ample moisture and overnight freezing temperatures enabling accumulation.
  • Hope for the future: NOAA Climate models are pointing to rising  chance of a weak El Nino by this coming Fall, with some similarities to the 2002-03 episode that produced a snowy winter in the East. Until then, the temperature trends are one reason why the current La Nina pattern drives us crazy -- see below for the flip flop that's coming in the next 2 weeks.
