A pool of cooler air has moved into the Finger Lakes region behind a departing area of low pressure now out over the northern Atlantic Ocean.
There is a very weak area of higher pressures overhead to start the day, with another small low moving across the Midwest. Clouds are widespread throughout the region, but there are a few small breaks in the overcast here and there.
For most of the daytime hours today, there will be little change from this morning. Skies will be cloudy with only a brief glimpse of the sun here or there. Winds will be light, if not calm. Temperatures will only rise a few degrees from the upper 20s and low 30s this morning to the mid and upper 30s this afternoon.
Snow will become possible late this afternoon. Across the Southern Tier, an area of light snow associated with the small low pressure system may clip the area. To the north, scattered lake effect snow showers will develop.
No accumulations more than a light dusting of snow are expected for either area through the early evening hours.
Scattered snow showers, primarily from lake effect on north and north-northwest winds, will persist overnight. Snow showers will continue on Wednesday, starting out mainly west of Seneca Lake and gradually moving eastward in the afternoon. Again, only minimal accumulations are expected.
Wind speeds will increase on Wednesday to around 10 mph, which will help pull down some additional cool air from Canada. Morning lows will be in the mid and upper 20s, with afternoon highs in the low and mid 30s.
A final chance for snow will come on Thursday as a warm front approaches. This should spread some widespread light snow through the area during the morning hours. Locally up to an inch may fall, and a few untreated surfaces may get a little slick.
Winds will turn to the southwest, however, and temperatures will start to creep upwards in the afternoon. Look for highs to reach the mid and upper 30s with a few of the typically warmer pockets near 40 degrees.
Warm, Wet, Windy Weekend
Temperatures will continue to rise late in the week and will peak this weekend.
Friday will hold the best chance for some appreciable sunshine. Even then, however, the sun will be mixed with some cloud cover.
South winds will persist, with morning lows Friday around 30 degrees but afternoon highs rising into the mid and upper 40s.
Saturday will be warmer yet, with widespread 50s for highs. However, sunshine will be harder to come by, and there is even a chance for some showers by Saturday evening.
The main weather event of the weekend will come on Sunday, and particularly Sunday night. A strong low pressure will pass through the area with rain and wind. Depending on the path and strength of the low, the rain could be heavy, and the wind could be strong.
However, the models have not yet stabilized enough with the track and strength of the low to determine with much confidence just how this will unfold in our area.
Cool air will move in quickly behind the low Sunday night into Monday. Temperatures on Monday will drop into the upper 30s, with 30s sticking around for a few days after that.
Lake effect development will be possible early next week as well, but at this time, looks as though it will primarily stay out of our region.
