Snow Updates

An area of low pressure will cross the Finger Lakes today with periods of snow, followed by some localized lake effect tonight.

Snow showers are scattered about the Finger Lakes this morning with more widespread precipitation to the north and west of the region.

These snow showers will continue to expand across the region this morning as temperatures rise. Some areas could see some rain mixing in, which is already occurring over Western New York.

Accumulations today should be minimal, with most of the region seeing an inch or less. Areas near and north of I-90 could see closer to two or even three inches.

Precipitation should taper off this afternoon as temperatures peak in the 35-40 degree range. With the milder temperatures, travel impacts from the snow should be minimal.

As the low passes through, winds will turn from the south to the west, then northwest later today. A couple narrow but impressive bands of lake effect snow will develop, especially between midnight and dawn.

This lake effect will just clip the edge of the Finger Lakes region, stretching from far eastern Wayne county, across northern Cayuga County, and into northern Onondaga county, including the Syracuse area. An additional 3-5 inches of snow could fall in these localized areas.

Weekend Weather and Beyond

Lake effect squalls will persist into Saturday morning but should dissipate by the midday hours.

Outside of the lake effect, skies will start rather cloudy with temperatures in the upper teens and low 20s. Sunshine should increase as the day goes on. High temperatures will be in the mid and upper 20s.

Temperatures will quickly drop Saturday evening into the teens and single digits. A south wind will develop overnight, and temperatures will warm from west to east. By Sunday morning, many areas will be back in the 20s, but parts of Central New York may still be stuck in the single digits.

After a little early sunshine, clouds will thicken on Sunday out ahead of our next weather maker. South winds will continue to drive temperatures upward though. Highs will range from the low 40s in the Rochester area to the mid 30s for Elmira, Ithaca, Cortland, and Binghamton.

Sunday night’s temperatures will drop a degree or two, but that is it. Precipitation should begin to work into the region before dawn on Monday, falling as rain. Periods of rain will continue through Monday.

Thankfully, the heaviest rain, on the order of 1-2 inches, should stay far to the southeast, reducing the risk of flooding.

Additional rain will also be likely on Tuesday. Temperatures both Monday and Tuesday will be into the 40s.

A cold front will move through late Tuesday, bringing our region back to winter briefly with some lake effect snow and cold temperatures. We should not be done with the milder weather though, with another warm up continuing to look likely for next weekend.
