       Meteorological winter began Wednesday and many of us even saw our first flakes of snow earlier this week. But what about the weeks and months ahead? Will this winter deliver some serious snowfall? Or will it be like most of recent years, with rather underwhelming amounts?

       We issued our winter outlook on Nov. 10 and predicted that we’ll see below-average snowfall for the fifth time in the last six winters. Specifically, we called for eight to 12 inches to fall at Reagan National Airport. The latest 30-year average at airport is 13.7 inches.

       Brace for a wild winter in Washington, but it’s no thrill for snow lovers

       But we’re far from the only outlet that issues seasonal snow predictions. Since issuing our winter outlook, we’ve rounded up the snow predictions from more than 30 other forecasters.

       The sad news, if you like snow, is that there’s a near consensus for below-average amounts.

       The reason pretty much everyone is on the same page stems from the La Ni?a conditions prevailing in the tropical Pacific Ocean. During La Ni?as, the storm track across the Lower 48 states tends to pass north and west of the Mid-Atlantic, drawing mild air into the region. So most storms tend to produce more rain than snow.

       But not every La Ni?a is the same. In fact, the winter of 1995-96 featured La Ni?a conditions and one of Washington’s snowiest seasons on record. Of course, that was an outlier but it shows there’s a possibility that the conventional wisdom could turn out wrong.
