I have noticed that March is decadal.
We had good March snows 1990 through 1999. Then we barely snowed in March 2000 through 2009. Then we had good snows in March 2010 through 2019. Of course non existent again 2020 onwards.
Phase 4 by the 22nd. Hopefully enough time left on the clock for another snowy period. Worst case is its too late but we end up with yet another cold and rainy spring.
