Weekend Weather Forecast
A pair of weather systems will impact the Finger Lakes during the long holiday weekend, but there will also be some nice weather sandwiched in between.
Much of the rain from the first system moved through during the overnight hours and is already east of the Finger Lakes. However, it should stay rather cloudy today with occasional showers spitting.
Temperatures are mostly in the 40s to start the day and will probably not move a lot during the daytime hours. This will especially be the case as winds turn to the northwest and increase during the midday and afternoon.
Wind speeds will be between 10-15 mph with gusts of 30-35 mph this afternoon. Highs will mostly be in the mid 40s but will begin dropping by the mid-afternoon.
The shower activity will increase during the mid to late afternoon as some lake enhancement off Lake Ontario begins to show up. Minor lake effect will continue into the evening, mostly turning to snow, with only a coating of accumulation expected.
The most likely areas to see this accumulation will be across the Cayuga, northern Tompkins, Cortland, and southern Onondaga counties. Temperatures will be marginal, so roadways should mostly stay clear and other, warmer areas will only see snow mixing in or not sticking.
The lake effect will shift north and dissipate in the predawn hours. Low and mid 30s are expected for overnight lows in the lake effect areas, but further from the lake, where skies may clear some, upper 20s are possible.
Saturday will quickly lose any lingering clouds for a bright, sunny day. Winds will be steady from the southwest, but not as strong, with top gusts in the 20-25 mph range. The sunshine and winds will push temperatures into the low 50s with a few higher elevations not quite reaching 50 degrees.
Rain will return Sunday morning, but it will be the afternoon and evening that will probably be the rainiest. While this system is not a powerhouse, it should be stronger than today’s with slightly higher rainfall amounts.
The temperatures on Sunday may be a bit interesting. After sitting in the mid 40s much of the day, a late surge of warmth could push temperatures to or above 50 degrees around and after sunset.
Sunday will be breezy with south, then southwest winds. Higher elevations will see the strongest winds with gusts to 35 mph.
Sunday night, winds will turn to the northwest with speeds near or over 10 mph. Cooler air will start to move in behind the weather system.
With plenty of lingering moisture over the area, these cool winds will team up with Lake Ontario for a showery day. Rain and snow showers will be likely throughout the day, though they should become less widespread. No snow accumulation is expected for the areas that see snow mix in.
The northwest winds will blow at around 10 mph with gusts around 25 mph. After morning lows in the mid 30s, highs will be around 40 degrees.
Skies may clear for a brief time Monday night, though lingering influences from Lake Ontario may limit that. Temperatures will average out around or just above 30 degrees, though again, if it clears, it may become cooler.
Clouds from the next weather maker will build in on Tuesday. A little sun may be possible early before becoming filtered by the thickening clouds. Overall, though, it should be a rather cloudy day. No precipitation is expected, however, and southerly winds should push temperatures to the mid 40s.
Wednesday will be the main chance for rain with this next system. Rainfall amounts look to stay under a half-inch. This system may have strong south winds, which will turn to the west late in the day. Strong west-northwest winds will then persist into Thursday with gusts over 40 mph a possibility.
Cold air will move in on these winds, holding temperatures in the 30s. Lake effect snow will develop off the lakes, but should stay outside of the Finger Lakes region.
The chilly air will not last, with 40s returning by Friday and persisting into the weekend. Another weather system should roll through late in the weekend or early the following week as our active, somewhat mild pattern continues.
