In the past few minutes, I've had a few weak sauce versions of what you recalled with such crystalline lucidity yesterday. A sudden roar of wind, a momentary darkening of the sky and a whipped bombardment of super wet flakes. Not of the same ilk as your changeover in '92, not by a country mile; these williwaws did not herald a permanent phase change--in fact it's back to mostly rain now--but there seemed a faint kinship with or echo of your memory in the proceedings that made me smile.
