Every year around this time, the KDKA-Goggle box weather team of meteorologists Ray Petelin, Ron Smiley, Kristin Emery and Mary Ours digs through the data and crunches the numbers to effigy out if we're in store for a mild or wild winter.

The Transparency:

First matter's first, nosotros know accountability is important. So we're going to tell you what went right and what went incorrect with terminal year's Winter Weather Forecast.

We got Nov correct, merely then December happened.

A whopping 27.5″ fell, making final December the second snowiest on record, and blowing our prediction out of the water. Or mayhap we should say out of the snow drift?

Our prediction was pretty shut for Jan, but February saw twice every bit much snow as we were expecting.

So while the seasonal forecast obviously was off, our daily forecasts were pretty spot on, and that's why we forecast every day. So now permit'south focus on what's to come this year.

The Setup:

Large-calibration climate patterns involving the tropical Pacific Ocean ofttimes touch on our winter weather condition. It has to practise with how warm water temperatures become.

For the second yr in a row, what's called La Niña conditions accept developed.

Commonly, trade winds button warm surface water toward Asia.

During La Niña, trade winds are stronger than usual, pushing fifty-fifty cooler water to the surface. That can impact temperature and precipitation across the U.Southward. by modifying the jet stream's position, making it wavier and causing more storms.

Climate models show an 87% chance of the current La Niña conditions continuing through February 2021. It typically produces cooler and wetter winters for southwestern Pennsylvania and the Great Lakes region. Nonetheless recent La Niña years have brought united states of america warmer winters or, like last year, a mix of higher up and below-average months.

The Temperatures:

With the overall warming trend over the past few decades, our boilerplate temperatures have been slightly increasing. But this year, we're forecasting slightly cooler than boilerplate temperatures due to a slightly negative Due north Atlantic Oscillation.

With this pattern, winds from the eastward and northeast are more frequent, bringing colder air.

The Pacific Decadal Oscillation, which fluctuates every 20 to thirty years, also plays a role.

During a cool or negative stage, the western Pacific Ocean becomes warmer and function of the eastern Pacific Bounding main cools, which also indicates below-average temperatures.

Now, when we talk almost average temperatures that doesn't mean we'll stay effectually the normal temperature every mean solar day. Nosotros could have days v to x degrees warmer or cooler than average and some days a difference of only a degree. In the end, it all evens out.

Here'southward how nosotros think this wintertime's temperatures will pan out:

–December volition end slightly warmer, at 34.0 degrees on average for the month.
–January will exist slightly colder, with an boilerplate of 27.7 degrees for the month.

You know those stories that outset off with "back in my day" and end up talking about snowfall piled over cars as people walked to school up colina both ways? Nosotros've all heard them, right?

Well, did people years ago actually see more snow back then or are we seeing more snowfall now?

Every ten years, the National Weather condition Service calculates our thirty-year snow boilerplate. We just got the new one, and information technology's really upwardly a couple of inches. A decade ago, the average was 41.9″. Currently, the boilerplate is 44.1″. That's because over the last decade, Pittsburgh has averaged 49.5″ of snow a year.

Then let'due south settle the historic period-old debate once and for all.

The 30-yr average from 1930-1959 was 36.2″. That means if you're over the age of 60, believe it or not, y'all saw the least amount of boilerplate snowfall a year compared to everyone younger than you.

The thirty-year average from 1960-1989 was 46.5″. Then that means if you're in your 30s, 40s or 50s, y'all actually did see more snowfall, on boilerplate, than everyone older and younger than yous.

And, finally, the xxx-year average from 1990-2019 was 44.1″. This means anyone under 30 has seen more snowfall than their grandparents, but not more than their parents.

The Snow – Future:

This winter we're expecting a little more snow than nosotros usually go far a winter, only not quite the well-nigh 58″ we got last twelvemonth.

For November, we're forecasting about two″ of accumulation, which is just a tad below average.

In December, nosotros're calling for ten″, which is a little above average.

January is normally when we go the nigh snow, and this Jan is looking especially crude with 17″ in the forecast.

February should be about boilerplate, with 12″.

Equally for March and Apr, as the last gasps of wintertime hang on, nosotros're forecasting 5″ spread over both months, which is below average.
