Winter's sudden arrival in the form of more than a foot of snow last week offered a tinsel-silver lining on at least two fronts -- a glimmer of hope for parched lakes and topsoil and a bounty of fresh powder for winter recreation enthusiasts.
Washington County, like much of Minnesota, has been in a severe drought pattern for much of the past year. The 15 to 20 inches of snow that fell across the county last weekend contained about ¾ to 1¼ inch of precipitation, said Greg Spoden, state climatologist with the Department of Natural Resources.
For December, "that's about a month's worth of precipitation in one event," Spoden said, and the most in a 24-hour period since July. "It's as if Mother Nature had forgotten how to precipitate -- but she relearned quickly."
Because the ground was frozen, little of that moisture will permeate the soil. "It isn't going to save us. We're still going to be very dependent on a very abundant spring rainfall," to make up what is a serious soil moisture deficit, he said. While Washington County was part of wide swath of the state's midsection that got snow, drought-stressed regions of the northwest and south didn't benefit.
The other good news from the snow, Spoden said, is that the ample insulation it now provides will keep frost depths shallow. That means frost will leave more quickly in the spring, and those rains that come will soak in better and more quickly.
This weekend promises to unleash much pent-up anticipation for winter recreation enthusiasts, who suffered through a relatively snow-free season a year ago, something Spoden calls "brown ground syndrome." Even though ski areas made snow and conditions were fine for skiing, the mood was affected.
"There's an emotional trigger to having snow on the ground -- at least that's my take on it," Spoden said.
That won't be a problem this season. And Washington County is awash in opportunities to enjoy the winter.
