Here were my thoughts with respect to March from last November:
March 2022 Outlook
March Analogs: 1956 (x2), 1984, 1996, 2006 (x2), 2001 (x3), 2018 (x2), 1975, 2011
The first half of March should be blocky with an improving Pacific. The month should feature both Miller A & B cyclogenesis, as there are signs that the subtropical jet may enter the scene in addition to the active northern stream. This could be a very volatile set up with immense storm potential should the two streams phase. There is a relatively strong chance of a KU magnitude event between March 1st and 15th. The failure risk is that the SSW does not materialize, which could alter the forecast dramatically.
Monthly departures anywhere from 1-3 degrees below average with the coldest across the interior and above average snowfall from the mid atlantic into New England. This should be a very active east coast pattern rivaling that of March 2018 and 2001, though with perhaps more southern stream involvement.
The pattern may rapidly break down later in the month with an early spring to reward beleaguered residents of the northeast if the vortex does indeed weaken a bit earlier than the Euro guidance suggests, as forecast by Eastern Mass Weather.
This March forecast, again, is contingent upon the development of high latitude blocking, and the risk is for a warmer outcome should that not occur. or be delayed, as the European guidance hints at.
Obviously the glaring error is with respect to the polar domain, as it appears as though the uptick in solar activity was enough to derail that. However, clearly the poleward Pacific ridging still holds the potential to deliver during that originally highlighted March 1-15 window.
