Wintry weather adds to Wednesday woes

Another storm in the train of weather activity is on the way for Long Island on Wednesday. A mix of snow, sleet, freezing rain, and rain is expected in various amounts.

Tuesday is an "in-between". Partly sunny skies are expected with highs in the mid 30s. Clouds increase late in the day. Traveling and the evening commute are dry, but icy spots are still around from Monday's storm, as well as any daytime melting.

A low pressure system rides up the Appalachian Mountain Range and heads towards Long Island. Its storm tracks puts the area "on the line" for a variety of wintry weather. Precip starts around midnight, give or take, as wet snow as temperatures should be near freezing. As the night progresses, watch for a changeover to sleet and eventually freezing rain by sunrise. A snow accumulation of 2 to 6 inches is possible before any changeover, with the lowest amounts south and east and the higher amounts north and west.

Significant ice accretion is possible, as even after a changeover, the rate of falling precipitation continues to be heavy into Wednesday's post-sunrise morning. Up to a quarter inch of ice is possible, making for an icy, crunchy mess.

With freezing rain, rain that freezes on colder surfaces near or on the ground, will be falling, surface temperatures will determine a changeover to plain rain during the day. A rise in some areas into the mid 30s translates to just rain, and this is more likely, but not guaranteed, for the south shore and East End.

Colder temperatures remain for the rest of the week with highs near 30 Thursday and Friday. Another storm is possible for the weekend time frame, but specifics won't be given until later in the week.
