This post was supposed to be up a few hours ago – before the snow started – but it started when the forecasts said it might start, but put down a quick half-inch. Normmally it takes 0.10 inches of rain to get an inch of snow, a 10 to 1 ratio of snow to rain. But today only 0.03 inches of rain made 1/2 to 1 inch of snow – a 20 to 1 ratio.
I’ll let the weather service take it from here…..
