A Winter Storm Warning for Otsego County until 1 p.m.; for Oswego, a cold, showery weekend
NWS Binghamton has a Winter Storm Warning for Otsego County until 1 p.m. Friday; nothing is listed for Oswego County. Here it's a cloudy Friday near 43 with a 30% chance of showers, then rain showers at 80% on Saturday and dry weather from Monday, warming to the low 50s by midweek.
Alerts: As of 8:27 a.m. Friday, the Weather Service listed a Winter Storm Warning from NWS Binghamton for Otsego County until 1 p.m. today. The warning says 6 to 12 inches of heavy snow had already fallen above 1,500 feet, with up to 2 more inches, and that heavy snow sticking to trees has led to power outages. NWS Binghamton's instruction: "If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency." The Weather Service listed no watches, warnings or advisories for Oswego County. Elsewhere in New York it listed Winter Weather Advisories for parts of eight counties, among them Chenango, Delaware and Schoharie, until 10 a.m. or 1 p.m. today, and coastal flood alerts for New York City and Long Island until noon to 3 p.m. On the water, the Lake Ontario marine feed listed Small Craft Advisories from NWS Buffalo for Hamlin Beach to Mexico Bay, the stretch that includes the waters off Oswego, with north winds of 15 to 25 knots and waves of 4 to 7 feet, until 9 p.m. tonight; Mexico Bay to the St. Lawrence River, with north winds of 10 to 20 knots, until 9 p.m. tonight; and the Niagara River to Hamlin Beach, with north winds of 10 to 20 knots and waves of 3 to 5 feet, until 3 p.m. today. NWS Buffalo's advisories say: "Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions." The New York feed listed no marine alerts.
It was a cold, grey night at the airport in Fulton: the temperature held between 35 and 37 from midnight on, under cloud the whole way, with no precipitation in the readings. At 8 a.m. Fulton was 36 and cloudy, with a north-northeast wind of 8 mph. Syracuse was 34 and cloudy at 7:54 a.m.
Today: A slight chance of snow showers before 9 a.m., then a chance of rain showers, at 30%, cloudy, with a high near 43 and a north wind around 13 mph, gusting to 23 mph, according to the Weather Service. New rainfall of less than a tenth of an inch is possible. My own blend of the forecast models has 40. Buffalo's forecasters expect "very little or no snow accumulation" at lower elevations today and tonight, with a coating to 2 inches along the Chautauqua Ridge and Bristol Hills.
Tonight: A chance of rain showers before 3 a.m., then a chance of snow showers, at 40%, with a low around 30 and a northwest wind of 7 to 10 mph. Little or no snow accumulation is expected. On the lake, Buffalo's forecasters expect small-craft conditions to end gradually before midnight, with very choppy water persisting this weekend and more small-craft conditions possible; no advisory beyond tonight's has been issued.
Saturday: A chance of snow showers before 7 a.m., then rain showers, at 80%, cloudy, with a high near 46 and a northwest wind of 10 to 15 mph. My blend has 41. Saturday night brings more rain showers, at 80%, with a low around 31. Buffalo's forecasters expect a brief uptick in showers Saturday into Saturday night, with a quick coating of snow possible at lower elevations and a coating to 1 inch on higher ground, including the Tug Hill Plateau.
The week ahead: Sunday is mostly cloudy near 46, with a 50% chance of rain showers before 1 p.m. (my blend has 43). Then it dries out: Monday partly sunny near 46, Tuesday mostly sunny near 51, Wednesday sunny near 53 and Thursday mostly sunny near 54. Buffalo's forecasters see afternoon temperatures rising "back into the lower 50s by Tuesday or Wednesday," with the warming trend reaching well above normal by Thursday.
