Early Week Weather
Low pressure associated with the remains of Tropical Storm Ophelia is stalled just off the Mid-Atlantic coast, while higher pressure dominates eastern Canada.
Here in the Finger Lakes, we remain on the edge of influence between these two systems. This will lead to some stark differences in the weather today, depending on your location.
Thick clouds are locked in place early this morning throughout the region, but skies over Lake Ontario are clear. Some of these clear skies will push south into the northern tier of the Finger Lakes region, especially later this morning into the first part of the afternoon. Clouds will push back in later in the afternoon.
The best chance for periods of sunshine will be near and north of I-90. Here, temperatures will push into the low and even mid 70s this afternoon.
Meanwhile, across roughly the southern half of the region, thick clouds will remain in place with some occasional showers. Rain will be most likely during the afternoon hours, though areas of drizzle and stray showers will persist this morning as well.
For these southern areas, temperatures will be about ten degrees cooler than they will be to the north, with highs mostly in the low and mid 60s.
There will be a narrow battle zone just south of I-90 where the weather conditions may vary throughout the day based on subtle influences on the boundary. Clouds will be more plentiful than sun, but rain will also be less likely compared to areas further south. High temperatures here will be in the upper 60s to perhaps low 70s.
Be sure to check your zip-code forecast for the exact details for where you live and work.
Winds today will be from the northeast early, then turning to the east and eventually southeast. Wind speeds will mainly be under 10 mph, but a few blustery gusts will be possible, especially in hilly terrain.
Skies will be uniformly cloudy tonight, though most of the clouds will be higher in the atmosphere and thus may allow for some moonlight to filter through. Overnight lows will generally be a couple of degrees on either side of 50.
Tuesday should be dry with cloudy skies in the morning, gradually turning over to some sun in the afternoon. By sunset, skies may be mostly clear throughout the region.
High temperatures on Tuesday will be in the upper 60s along and north of I-90, with mid 60s further south, and low 60s in higher elevations.
Winds will remain generally easterly with speeds close to 5 mph.
Thin clouds will eventually move back in Tuesday night, but temperatures will still turn cool with lows mostly in the mid 40s but dropping to near 40 degrees in and near Cortland County.
Late Week and Weekend Weather
Wednesday will be a quiet day. The sun will shine between and through thin clouds that will be passing through the area, though the clouds may be a bit thicker in the afternoon. No rain is expected.
High temperatures will again be in the upper 60s to the north, with mid 60s to the south. Most higher elevations should also reach the mid 60s.
East winds will continue with speeds again around 5 mph.
Some clearing will take place Wednesday evening, but occasional thin clouds will still be possible. Overnight lows will primarily be in the mid 40s.
Winds will turn to the southeast on Thursday with increasing clouds. A few scattered showers will be possible late in the afternoon and into the evening hours. Many areas will probably not see rain.
Thursday’s afternoon highs should be a couple of degrees warmer than Wednesday, with more areas into the upper 60s. A few areas around Dansville, Rochester, and Syracuse may hit 70 degrees.
Scattered showers will continue into Friday, though again, at least some of the region will not see rain. Temperatures will hold steady in the upper 60s to near 70 degrees, with mid 60s in the higher elevations.
The weekend will be dry with sun and fair weather clouds on Saturday and mostly sunny skies on Sunday. Temperatures will trend upward with low 70s Saturday and mid 70s Sunday. Overnight lows should mostly be at or above 50 degrees.
The start of October next week looks quiet and warm, with daily highs in the 70s and low chances for rain. Nighttime temperatures should remain in the 50s.
