Showers end by early afternoon, then a cooler Friday and a wet Saturday
Thursday's showers taper by early afternoon, with a high near 68 early and temperatures falling to around 59 behind a cold front. Friday is mostly cloudy and near 61, and showers return Friday night, at 80%, and Saturday, at 90%, with a high near 54.
Good morning, Oswego. It was a warm, wet night: the airport in Fulton reported light rain from about 1 a.m. to 5 a.m., never dropped below 59 degrees (first reached at 3:20 a.m.), and was 59, cloudy and calm at 6:54 a.m. Syracuse was 66 and cloudy at 6:54 a.m., with a south wind around 8 mph.
Alerts: As of 7:52 a.m. Thursday, 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 a Small Craft Advisory from NWS Buffalo for the nearshore waters of Lake Ontario from the Niagara River to Hamlin Beach, from 10 a.m. to 10 p.m. Thursday, for southwest winds of 15 to 25 knots and waves of 3 to 5 feet; it does not cover the waters off Oswego. NWS Buffalo's advisory says "Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions."
Today: Rain showers likely before 2 p.m., a 60% chance, with less than a tenth of an inch. Mostly cloudy, with a high near 68 early and temperatures falling to around 59 in the afternoon, and a southwest wind of 9 to 13 mph, according to the Weather Service. My own blend of the forecast models has 67. Buffalo's forecasters expect the showers to exit the region by mid-morning, with breezy conditions today.
Tonight: Mostly cloudy, with a low around 49 and a south wind of 3 to 7 mph. Less than a tenth of an inch of new rain is possible.
Friday: Mostly cloudy, with a high near 61 and a northwest wind around 5 mph, and a 20% chance of rain showers after 4 p.m. My blend agrees, at 61.
The week ahead: Rain showers Friday night, an 80% chance, with a low around 42, then showers Saturday and Saturday night, a 90% chance, with a tenth to a quarter of an inch each period, a high near 54 and a low around 38. Sunday is partly sunny and near 54 with a 50% chance of showers and a west wind of 13 to 16 mph, gusting to 25 mph Sunday night; Monday is near 53 with a 49% chance of showers. Buffalo's forecasters expect lake-enhanced showers east and southeast of the lakes from Friday night through Saturday night, and say confidence in the rain chances decreases from Sunday as the models diverge. My blend runs 2 degrees cooler than the Weather Service on Saturday and Sunday, at 52.
