The National Weather Service has issued Winter Weather Advisories (purple) for most of the Finger Lakes in anticipation of accumulating snow Tuesday.

Calm Today Before Snow

An area of high pressure overhead will bring a quiet day to the Finger Lakes, but low pressure developing over the Deep South will bring wintry weather back tomorrow.

Today’s weather will be very quiet with clouds mixing with a little sun, light winds, no precipitation, and typical mid-December temperatures.

Temperatures range through the 20s early this morning to start the day and will rise to a high in the low and mid 30s. The best chance for some sun will come toward the middle of the day before clouds increase from the south.

Most of the overnight will also be calm and quiet, but snow should start to push in from the south during the predawn hours. Snow will continue throughout much of Tuesday before tapering off late in the afternoon.

The Finger Lakes will be on the northern edge of this system. Areas north of I-90 should see minor accumulations, while the Southern Tier has the best shot at some moderate accumulations, on the order of 3-5 inches.

The National Weather Service has issued Winter Weather Advisories for areas near and south of I-90 to alert the public of the snowy conditions expected. While not a major storm, travel will be impacted throughout Tuesday, requiring some extra commute time and due caution from drivers.

I will have my full Snow Report this afternoon with a complete breakdown of the impacts from this system.

Squalls and Cold

Winds Tuesday will be light but will become blustery from the northwest behind the system on Wednesday.

Conditions are favorable Wednesday for on and off squalls throughout the day. Combined with wind gusts over 30 mph and temperatures in the 20s, travel conditions will continue to be less than favorable with blowing snow, slick roads, and periods of poor visibility.

By Thursday morning, temperatures will fall into the single digits. Areas of lake effect will continue to be possible southeast of Lake Ontario but should be less widespread than on Wednesday. The lake effect will gradually dissipate as high pressure moves in overhead on Thursday.

Temperatures will be very cold though, with highs not escaping the teens.

High pressure will then move to the east, allowing warmer air to move back in on south winds. Friday should push well into the 20s, while Saturday reaches the 30s and Sunday makes a run at 40 degrees.
