Snow Estimates Increase: Tuesday's Hudson Valley Storm

Snow and rain continue to be in the forecast for a storm Tuesday that is poised to move through the Hudson Valley. However, even since the forecasts posted Monday morning, there have been changes in what can be expected.

Parts of the Sound Shore were earlier thought to have little or no snow accumulation by nightfall Tuesday. Now there's excepted to be a half-inch or less of snow.

And at 3:44 p.m., the National Weather Service issued a winter weather advisory for Orange, Putnam, Rockland and northern Westchester counties in effect from 6 a.m. Tuesday to 6 a.m Wednesday.

Snow total estimates have increased for that area from a light accumulation to 2 to 5 inches.

The NWS said that motorists should plan on slippery road conditions, and the hazardous conditions could impact the morning and evening commutes.

So when will it all start? The meteorologists at Hudson Valley Weather said the timing on Tuesday will see light snow developing from west to east from 8 a.m. to noon, moderate to heavy snow from 1 p.m. to 8 p.m., snow possibly mixing with rain south of I-84 from 3 p.m. to 7 p.m. and snow tapering from west to east 7 p.m. to 11 p.m.

Here is the latest forecast from the NWS for northern Westchester County:

• Monday Night: Increasing clouds, with a low around 21. Calm wind becoming southeast around 5 mph after midnight.
