Forecasters say timing of snowfall could push accumulation to 8 inches in Berks

Feb. 12—Rain will arrive in Berks County this evening and switch to snow overnight or early Tuesday morning under a winter storm watch, forecasters said.

The timing of that changeover will determine how much snow accumulates, with the possibility of more than a half-foot landing in Berks, forecasters said.

Monday's temperatures will reach the lower 50s before gradually dropping, with rain likely to start around 8 or 9 p.m., said Tom Kines, senior meteorologist with AccuWeather's State College station.

The rain will stop and snow will most likely start falling around daybreak and last until about noon, amounting to 1 to 3 inches in Berks, he said.

But if the snow starts a few hours earlier it will likely be falling at an inch an hour and greatly increase the accumulation, he said.

In that case Berks could get up to 7 or 8 inches, he said.

If the switch from rain to snow instead happens an hour or two after daybreak, Berks will probably only get an inch or so, he said.

"If the changeover is off a few hours it will make a huge difference," he said.

The timing could also affect the morning commutes for many, as well as school openings, he said.

The snow will be wet and heavy to shovel, but if you don't clear it during the day Tuesday — when temperatures should be in the lower 40s — it will likely freeze at night with temperatures expected to drop to below 30, he said.

On Wednesday afternoon the temperature should peak in the upper 30s under sunny skies, but the wind will make it feel colder, he said.

Thursday should get close to 40, and Friday will likely reach the lower 40s, he said.

Saturday there is a chance for another mix of rain and snow, while Sunday is expected to be dry, he said.

There is the possibility of another accumulating snow event Monday, but that forecast is still up in the air, he said.
