Winter weather advisory posted Tuesday; commutes likely to be affected

A winter weather advisory is posted across Western New York for Tuesday.

Forecasters said a complex storm system will bring a wintry mix of precipitation across the region starting tonight through mid-week.

Tuesday looks to be the trickiest day with multiple types of mixed precipitation expected.

Snow and mixed precipitation is expected. Between 3 and 6 inches of snow is expected along with as much as 0.1 inch of ice and winds up to 40 mph.

Forecasters said the winds could bring down some tree branches and cause isolated power outages.

"Snow will develop late tonight, then change to mixed precipitation on Tuesday," the weather service said. "Travel could be very difficult with snow and ice-covered roads and reduced visibility."

The weather service added: "The hazardous conditions will impact the morning and evening commute on Tuesday."

Forecasters expect the precipitation to start as snow tonight and into Tuesday morning.

It could mix with sleet and freezing rain Tuesday, turn over to plain rain later Tuesday and Tuesday night, and return back to snow by early Wednesday.

A few hundredths of an inch of ice is also possible across the southern half of the region between early Tuesday and early Wednesday, the weather service said.

In the meantime, the weather service calls for a 60 percent chance for snow showers and freezing drizzle early today then chances for snow showers through the rest of the morning Monday. Otherwise, it's expected to be mostly cloudy with temperatures near 30 degrees.

Chances for snow increase late Monday into early Tuesday.

By Tuesday, forecasters said there's a 100 percent chance for precipitation.

The weather service expects:

  • Snow and sleet before 2 p.m. Tuesday.
  • Rain and sleet during the mid-afternoon.
  • Rain during the late afternoon.

New snow and sleet of 3 to 5 inches is possible, the weather service said. Tuesday's high is forecast in the upper 30s. It'll be breezy, too.

"As we move through Tuesday and Tuesday evening ... a surge of milder air – first aloft, and then at the surface – will push into western New York," the weather service said. "This will result in the snow giving way to a wintry mix and eventually a cold rain for the bulk of the area south of Lake Ontario where surface temperatures currently look to climb into the mid to upper 30s later Tuesday and Tuesday evening."

Rain is expected late Tuesday with up to one-half inch of precipitation possible and gusty southwesterly winds with lows in the 30s.

The precipitation is expected to change back to snow for Wednesday with highs in the low 30s. It could be windy as well, forecasters said.
