Snow Showers Expected on Christmas for New York

Bryan Dijkhuizen

Several mild disturbances will pass across the area during the rest of the workweek, bringing the possibility of a few scattered snow showers. According to forecasters, a more powerful storm is expected to deliver more widespread precipitation to the area on Christmas Day.

The most significant change was an increase in cloud cover. Large, dense clouds blanket the bulk of the region, and they will continue to move southeast during the day.

Low clouds originating off the coasts of Lakes Ontario and Erie will erode, and in the Poconos and Wyoming Valley will dissipate to the southeast as the day goes on. This is the northernmost edge of the coastal storm that affects the southeast.

Temperatures will be near to average for the winter solstice, with soft breezes and dry conditions throughout the day.

By Wednesday night, the flow will have shifted from being westerly to more northwesterly, and it is predicted that lake effect snow showers will move southward into the Finger Lakes Region.

Due to the relatively solid and unidirectional flow associated with the storm, the bands of lake effect snow showers are expected to stretch very far inland, maybe as far east as the I-88 corridor and the Catskills.

Despite these conditions, moisture will be in short supply, and snowfall quantities will be modest.

Up to another 1-2 inches of snow is forecast for parts of Onondaga and Madison counties as well as central Cayuga county in the southern half of the state. Elsewhere, quantities will be less than an inch, with just a few tenths of an inch possible in the I-88 corridor.

Lake effect snow showers are not likely to make it to the Southern Tier of New York or farther southern at this time.

Warmer temperatures are expected to be in the mid-teens to mid-twenties, with some lower teens possible in far northern Oneida County.

High pressure and mild ridging will allow for otherwise dry weather on Thursday, apart from a few brief lingering morning snowflakes throughout the Finger Lakes Region.

Weather will be mostly bright, with some clouds in the afternoon ahead of the next weak system, while clouds are anticipated to rise throughout the afternoon.

The high temperatures are forecast to be in the upper 20s to mid-30s this weekend.

A weak shortwave will travel over the region throughout northern New York State and southern Canada on Thursday night. The possibility of scattered snow showers over Central New York will be present late Thursday night and into early Friday morning.

Although snow showers are not completely ruled out in Northeast Pennsylvania, the likelihood of them occurring will be much lower the further away from the shortwave you are. Low temperatures are forecast to remain in the 20s for the most part.
