WEATHER UPDATE: 'Potentially Treacherous' Tuesday Evening Commute

You might want to sneak out of work a little early today, just to be on the safe side.

And while you’re at it, you might want to call out in advance for Thursday, where up to six inches of snow is possible late Wednesday into Thursday afternoon.

Yes, more snow is forecast for tonight’s commute home from work, as snow is expected to begin falling around 4 p.m. and be relatively heavy in intensity, before it changes to ice late Tuesday, and then some light rain showers on Wednesday.

“Snow breaks out from west to east, just in time to make a mess of the Tuesday evening commute,” says Bill Potter from Hudson Valley Weather. “ You’ll want to allow extra travel time for your PM commute, because the snow should be falling quite steadily at that point. An inch or two is possible by the time the sun sets.”
