The 45-degree winter weather respite is over.

Less than a week after nor'easter Nemo slammed the Hudson Valley with 2013's largest snowfall, another storm on the horizon is threatening to add a fresh coat of snow Wednesday, just as the old slush was finally melting.

Wednesday's storm will start out with rain before a steep temperature drop from the low 40s to the mid-20s after sundown, the National Weather Service forecast predicted. Once the temperature drops below the freezing mark, the rain will become snow.

Although the storm could drop up to 3 inches of snow overnight Wednesday before it passes Thursday morning, News12 meteorologist Joe Rao said the mid-Hudson Valley area could be spared.

Some forecast models predict the storm will sweep over the Hudson Valley; others show the storm moving east off the coast by the time it arrives Wednesday.

The good news? It won't be anything like last week.

"We'll take the middle road and say that tomorrow night, maybe about an inch or so," Rao said. "Maybe a little bit more in southern Westchester, maybe a little less to the north, but we're not looking for any major outbreak of snow this time around."
