Does winter still have a closing act for the D.C. area? [View all]

March is fickle, and it’s premature to rule out more cold weather and even snow.

'Springlike warmth has arrived in the D.C. area, and, with several straight days of 70-degree weather predicted, it may seem as though winter has ended. But we need to be careful about jumping to that conclusion.

March is a notoriously fickle month, and we probably have at least one bout — if not two — of cool or even cold weather to come. It is also too early to rule out any more snow or mixed precipitation.

When it could get chilly again>>>

We have a chance to hit 70 degrees or higher daily through Friday, marking our warmest stretch of weather since the first half of November. On Tuesday afternoon, the mercury climbed to 72 degrees in Washington, the warmest since Nov. 10 (when it was 76). But high temperatures will ease back into the 50s over the weekend as a cold front pushes south through the area on Friday night.

Next Monday is when things could turn a little interesting and, for those who are over winter weather, disheartening. While models still show a range of possibilities, highs could get stuck in the 40s. Not only that, the American model is hinting that we could see a mix of rain, sleet and snow, as high pressure to the north feeds cold air south at the same time that moisture streams in from the west.

The European model does not hold the cold air in as long as the American one does and delays the onset of any precipitation until it is too warm for anything but rain. Regardless of which model is right, early next week will probably bring periods of raw, chilly weather.

We’ve seen snow well into March a few times in recent years.>>>
