How often does Rochester see spring snow?


ROCHESTER, NY (WROC) – After 4 straight days spent in the 60s in western New York this week, many are starting to feel “spring fever” taking hold across the region.

Each year we make the transition from winter to spring during the month of March, and during this transition we get “glimpses” of the warmer months to come with a brief period of milder weather. More often than not, we are often fooled by this beautiful period of time when in reality we may not be quite done with temperatures and rainfall that feels like a more wintery feeling.

Living in western New York, it’s no surprise that the first day of spring doesn’t necessarily mean we’re done with the snow. If you are wondering how often we see snow in the spring, you have come to the right place.

The data below shows the number of days within the meteorological spring (March, April, May) since 2010 that contained at least 0.01 ″ of snowfall. So far this year we have only had 3 days with at least this amount of snow.

The data below shows the number of days within the astronomical spring (March 19 to June 19 to account for the change in the start date of each season) since 2010 that contained at least 0.01 ″ of snow. So far, during the astronomical spring of this year, Rochester has experienced 0 days with recorded snowfall. However, every previous year over the past 10 years has seen at least a few days of snowfall recorded from March 19 to June 19.

With that in mind, the question is what time do we typically see snow in Rochester? I have unearthed some numbers and the dates I have found may or may not surprise you.

Every year for the past 5 years (and beyond), Rochester has seen at least some trace of measurable frozen precipitation linger through the months of April and even May.

Another question you may be thinking about now is, with the odds in our favor of seeing at least some sort of frozen precipitation after this point, when will we see it? Will it snow again this month and how much?

It’s always a fun game that we meteorologists play with Mother Nature at this time of year when we predict snow at this time of year. Often times we have several strong storms oriented in such a way that a large part of the area is engulfed in the warm sector and sees rain, but when it comes out of our area it brings colder air to the area. ‘back. This air can be cold enough to withstand spring flakes, and given the nature of these storms, they can also bring strong and destructive winds. When we move from the cold season to the hot season, our region is subject to greater temperature variations than usual, and therefore stronger storm systems.

The weather knows no bounds as to the month for example, but it’s more likely than not that these storm systems aren’t huge snowmakers as we move into warmer temperatures that last longer and with less. cold air intrusions. In the end, while it sometimes seems like winter will never end, the weather is inevitably on our side… eventually.
