Not ready for the three-day weekend to be over? Good news: D.C.’s weather experts are predicting school cancellations in the wake of Tuesday’s snowstorm.

The Washington Post’s Capital Weather Gang is “unusually confident” that the D.C. area will see moderate to heavy snow: four to seven inches starting around 7 a.m. The Post meteorologists predicted that the mix of chilly air and wet snow would pile up on streets, likely leading to school closures and flight cancellations.

The National Weather Service issued a winter storm warning until 11 p.m. Tuesday, predicting the heaviest load of snow between mid-morning and early afternoon.

Temperatures are expected to dip into the teens and winds could push snow into the roads by late afternoon.

It’s not exactly the return of the polar vortex – the severe chill that gripped the country as far south as Mississippi about two weeks ago, which also caused pipes to burst at the GW Hospital, flooding more than 30 rooms.

“We are not gamblers but would bet that the (record long) two inch snowstorm drought in D.C. (dating back to January 26, 2011) will come to an end tomorrow,” the blog reported.
