Saturday Update
Winter Weather Advisories have been issued for the southern half of the Finger Lakes region in anticipation of icy conditions Sunday morning and early afternoon.
After a quiet, sunny Saturday, clouds will thicken overnight and precipitation will begin to move into the area during the predawn hours.
Warm air will move in aloft, but surface temperatures will remain colder. For much of the southern and eastern Finger Lakes, temperatures will remain below freezing.
Freezing rain will be the dominant precipitation type across the southern and eastern Finger Lakes, while further north and west, plain rain will fall. Precipitation will turn to rain from northwest to southeast and from lower elevations to higher elevations. By the early afternoon, much of the precipitation will be over, and the spits that remain will be plain rain.
Personally, I do not completely agree with the placement of the Winter Weather Advisories, and, in particular, would have included southern Cayuga and Onondaga counties for a glaze in the lower elevations and a tenth of an inch or locally more in the hills.
Most lower elevations in the Advisory areas should see under a tenth of an inch of ice. Higher elevations, mainly east of Seneca Lake, will have the best shot at over a tenth of an inch of ice.
Given the cold temperatures Friday, Saturday, and Saturday evening, road temperatures are likely to be well below freezing early Sunday morning. This will lead to ice accumulation on untreated roadways, making for slippery conditions.
Delaying travel until later in the morning, and then sticking to the primary, treated roads is advised. Know your local conditions and make appropriate judgments, though. Travel conditions will vastly improve during the afternoon as temperatures warm well above freezing.
South winds will also gust to 30 mph in lower elevations and to 35 mph in the hills. With the added weight from the ice, some sporadic power outages may result. Most areas should not lose power.
An evening cold front will set up lake effect snow for a time Sunday night, but most of the activity should lift north for Monday.
