Latest Details on First Snow, Sleet for Yorktown.

SOMERS, NY — It appears much of the Hudson Valley could see the season's first snowflakes. And first sleet. And first wintry mix.

No real accumulation is expected but the Thursday morning commute could be affected.

The National Weather Service has issued a notice for Orange, Putnam, Rockland and northern Westchester to warn local travelers:

• Special Weather Statement

The NWS says a light mixture of snow and sleet is expected to begin after midnight across Orange and Rockland. There could be light accumulations by morning rush hour. Then on Thursday morning, we get treated to the classic wintry mix before the precipitation changes to all rain. Accumulations: a trace to maybe an inch or more in western Orange County.

"Aside from the front end snow threat, a beneficial rainfall is likely, up to an inch of rain will fall across the areas that do not remain snow, even some thunder in the heavier downpours is possible," said Alex Marra of Hudson Valley Weather.

Since the Hudson Valley is still classified in severe drought, the rain will be welcome. But it will feel raw out there, so dress appropriately. Plus, even without snow, the combination of rain and fallen leaves can make roads extra slick.

Here's what's in the immediate forecast for northern Westchester County:

Tonight
Mostly clear this evening...then becoming mostly cloudy. Cold with lows around 30. Northeast winds around 5 mph.

Thursday
Rain likely with a chance of snow in the morning... Then rain in the afternoon. Highs in the mid 40s. East winds 5 to 10 mph. Chance of precipitation near 100 percent.

Thursday Night
Showers...mainly in the evening. Not as cool with lows in the mid 40s. Southeast winds 5 to 10 mph...becoming west with gusts up to 20 mph after midnight. Chance of rain near 100 percent.

Friday
Mostly sunny. Highs in the mid 50s. Northwest winds 15 to 20 mph with gusts up to 30 mph.
