Snow Possible Tuesday Along With Record-Breaking Cold

Brrrr. If you think it feels more like January than early November, you’re not alone. Temperatures have taken a nose dive throughout the area due to an invasion of Arctic air; an invasion that will receive a reinforcement Tuesday, when what could be the first significant snow of the season is also possible.

If the thought of snow this early in the season brings back unwelcome memories of last year’s freak November snowstorm–which paralyzed much of the Lehigh Valley when it dumped up to eight inches of powder during rush hour–you need not fret, at least not yet. As of Saturday evening most weather forecasters were limiting expectations for the possibility of any accumulation.

The National Weather Service didn’t address the likelihood of any accumulating snow in its latest near-term forecast for Allentown, although it is forecasting a changeover from rain to snow on Tuesday, as temperatures tumble from the 30s into the teens.

Wednesday’s high temperature is forecast to be just 33 degrees, which is about 20 degrees below normal for this time of year.

The low temperature Wednesday night could potentially be record-setting, as Saturday morning’s low of 20 degrees nearly was. Had the mercury dropped just one more degree–to 19–at Lehigh Valley International Airport, a record set in 1967 would have been tied.

Record or not, temperatures Saturday averaged about 15 degrees below normal, which meant that anyone who was performing fall leaf pickup likely had to be bundled up.

So who is forecasting the possibility of accumulating snow?

The website Pennsylvania Weather Action Saturday published a post by forecaster Josh Adams Saturday evening in which he outlined two potential scenarios for the Tuesday storm, including one in which the Lehigh Valley area could potentially see 1 to 3 inches.

An alternative scenario would mean more rain, and snow accumulations of less than an inch on grassy surfaces only, according to Adams’ post.

“We will know more by Sunday evening, which is when you can expect our snowfall forecast,” Adams said.
