Spring’s arrival no guarantee snow season’s over
Now that the three-month meteorological spring season is underway, history tells us the area’s “normal” daytime highs are likely to surge an average of 35 degrees over the coming three months and that sunshine here is to expand by well over three hours. But, it’s quite likely the area—despite a lackluster 20.3” season snow tally to date—hasn’t seen the last snow. Weather records indicate snow has fallen measurably beyond March 1 an average of six times totaling 8.1”. The numbers in a particular year can vary widely. A March 25-26 snowstorm in 1930 generated 22.3” of snow—one of the city’s biggest single snows ever. Another March snowstorm a year later between the 7th and 9th buried the area beneath 19.5”.
A few flurries are possible Thursday, but a disturbance Sunday night and Monday is the first with even the potential to produce more. That’s far enough into the future to suggest that system isn’t yet carved in stone.
