The last full day of winter in the District. (George Jiang via Flickr)

Clouds were a little slow to clear the area this afternoon, keeping temperatures a few degrees cooler than expected. The last overnight period of the winter season will be cold but tranquil. A quiet end to a rather dull season.

Through tonight: Clouds will continue to diminish through the early evening, leaving mostly clear skies overnight. A gusty north wind (15-plus mph) will persist through sunset before tapering off after dark. Expect a cold night around the region, with low temperatures ranging from 26 to 30 degrees in the suburbs and from 32 to 35 in D.C. proper. North/northwest wind at 5 to 10 mph.

Tomorrow (Monday): The weather is extra transitory tomorrow. High pressure is temporarily in control through the early afternoon, and temperatures will push into the upper 50s under mostly sunny skies. Wouldn’t be surprised to see a few 60-degree readings, too. High pressure moves offshore by the late afternoon, changing the wind to a more easterly flow. Clouds build in quickly with overcast skies by 5 to 6 p.m. Showers will pass through the region tomorrow night with low temperatures in the low to mid-40s.

Warm spring ahead?: Congratulations, friends, with spring officially starting tomorrow morning, we’ve nearly made it through the winter of 2016-2017. I hope you didn’t blink, or you might have missed it. We will provide a more in-depth look at the “Winter That Wasn’t” later this week. But humor me for a few minutes as I provide a crude statistical analysis to give some insight on what we can expect over the next three months.

It has been warm: With less than a day to go, this winter’s unofficial average temperature is 44.1 degrees. Should that number verify, it makes this winter the second-warmest in the District in 36 years.

Warm winter, warm spring?: Angela and Matt touched on this subject a few weeks ago — namely, whether a warm winter equates to a hot summer. Here, we are taking a very one-dimensional look at any correlation between warm winters and warm springs.

Top 20 warmest springs (March 20-June 21) on average. Measured at National Airport. Period covers 1970 to 2016. Via Cornell.

And we find some correlation. Three of the top five years with the warmest average winter temperature ended up in the top 25 for the warmest average spring temperature. And the more rigorous scholars of statistics will be quick to point out that I had to expand the warmest-spring list from the Top 5 to the Top 25, which is a bit of a manipulation of the numbers. I told you this was a crude analysis!

So, the takeaway message is that a mild (if not at times hot) spring season is more likely than not in 2017.
