A wet Saturday near 41 in Oswego; Small Craft Advisories on Lake Ontario into Sunday morning
Rain showers are likely today, at 70%, with a high near 41, and again tonight. Sunday dries out near 46, and the sun returns early next week, with highs in the low 50s by Tuesday and Wednesday. On the lake, NWS Buffalo has Small Craft Advisories for the waters off Oswego until 10 a.m. Sunday.
Good morning, Oswego. It was a raw night at the airport in Fulton: from 11 p.m. Friday the temperature stayed between 34 and 37, with light rain on and off and 0.01 inch measured in the hour to 6:54 a.m. At 7:25 a.m. Fulton was 37 with light rain and mist, 4 miles' visibility and a northwest wind of 6 mph. Syracuse reported light snow from 5:54 to 7 a.m., and at 7:29 a.m. it was 36 with light rain.
Alerts: As of 7:52 a.m. Saturday, the Weather Service listed no watches, warnings or advisories for Oswego County or for any land area in New York. 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 northwest winds of 15 to 25 knots and waves of 3 to 6 feet, from 6 a.m. today until 10 a.m. Sunday; Mexico Bay to the St. Lawrence River, with northwest winds of 10 to 20 knots and waves of 3 to 5 feet, from 1 p.m. today until 7 a.m. Sunday; and the Niagara River to Hamlin Beach, with northwest winds of 15 to 25 knots and waves of 3 to 5 feet, from 10 a.m. today until 4 a.m. Sunday. 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.
Today: Rain showers likely, at 70%, cloudy, with a high near 41 and a northwest wind of 10 to 16 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 agrees on 41. Buffalo's forecasters expect the showers to become more widespread and steadier from late morning through early evening, with mainly rain at lower elevations through the afternoon and wet snow on higher ground.
Tonight: Rain showers likely, at 60%, with a low around 31 and a northwest wind of 12 to 16 mph. Buffalo's forecasters expect a rain and wet-snow mix this evening and overnight at lower elevations.
Sunday: A slight chance of snow showers before 7 a.m., then a slight chance of rain showers, at 20%, mostly cloudy, with a high near 46 and a northwest wind around 12 mph. My blend has 43. Sunday night is mostly cloudy with a low around 33. Buffalo's forecasters expect the lingering showers to end from west to east Sunday afternoon through evening, with any snow at lower elevations 0.5 inch or less. On the lake, they expect waves mostly 3 feet or less from Sunday, with occasional 4-footers Sunday morning and again Tuesday into Wednesday, and say they are watching for "the potential need for an additional Small Craft Advisory"; none beyond the current advisories has been issued.
The week ahead: Monday partly sunny near 48 (my blend has 45), Tuesday sunny near 52 and Wednesday mostly sunny near 54. Buffalo's forecasters expect highs "back to above-normal levels by Thursday," mainly in the mid 50s to lower 60s across their area.
