Meteorological Winter ends on Thursday as we turn the calendar to March. Here's a look at some of the averages and extremes for the month.

March can be a very active month through the D.C. area with everything from thunderstorms to snow storms possible. The month averages 1.3 inches of snow and 3.43 inches of precipitation. The difference between the record high and record low is 89 degrees which is only behind December and January, so variability is common. Just in the past 5 years temperatures have been recorded in the lower 80s as well as the teens. Here's a look at the month as a whole including the averages, extremes, past 5 years and a look to the March we have ahead of us.

A Look Ahead:

A look at the graphic below shows the Climate Prediction Center's thoughts on the month of March with temperatures well above normal from the Plains to the East Coast. Above normal precipitation is expected for the Midwest but they think it should be below normal for the southeast. I think we'll actually start off the month cool and wet by the 3rd but gradually take over with warmer than normal temperatures. As far as precipitation, I do think we will be right around normal. Do I think the D.C. area will see snow this month? Nope. I think we're done as far as that's concerned. I still think it is safe to say we will fall into the 30s during the month though I'll go out on a limb and say we'll push 80 degrees by later in the month.
