March Was Colder Than February In Many Areas

So far, interesting weather has marked 2017. “Big” is the common theme to this year’s weather. Big rain, snow, and floods occurred in California. Big storms hit many parts of the country. And, the Northeastern US saw a big flip in typical temperatures in February and March.

Queue the Eye Candy…

Recently, a few weather geeks here at Weather Source pondered the ebb and flow of temperatures this winter. One of the (not-to-be-name) geeks mused, “March was a lot colder than February”. I said, “prove it”. And so, a short time later he sent image below. It is an analysis of OnPoint Weather showing average daily high temperatures for March differenced with average daily high temperatures for February. In the image, blue means March was colder than February, which was the case for much of the Eastern US.Considering March has the benefit of significantly more hours of sunshine, this cold flip is quite remarkable.

The Trend Over Time

The next image shows how this unfolded. In this chart we plot daily max temperature (dark orange) and corresponding climatology (light orange) from a point in the Northeastern US. This data is available in our OnPoint Weather database. The vertical line in the middle of the chart separates February and March. We see a sizable portion of February was well above normal, with a couple days in the 70s. By contrast, March temperatures were well below normal with a few days with daily max temperature below 20°F.

So there it is – the Big Northeast Temperature Flip of 2017.  Weather anomalies like this don’t typically get much press compared to big storms and floods. This big flip has most certainly had economic impact.  We’re only 3 months into 2017 and it looks like more crazy weather will be heading our way.
