The Finger Lakes will be subjected to another frontal passage overnight tonight.
Clouds streaming out ahead of the front are already building into the region. These are mainly thin clouds high in the atmosphere but the cloud cover will thicken up as the day goes on. Also present this morning are some low clouds and fog.
The best chance for some sunshine will be during the morning hours as the low clouds and fog burn off and before the new clouds thicken.
The afternoon should turn out mostly cloudy, and a few stray showers or small thunderstorms may even develop during the late afternoon hours. The further west, the greater the chance for one of these showers.
Despite the clouds, southwest winds of 5-10 mph will help warm temperatures this afternoon. Most places should be in the upper 70s, with a few pockets around 80 degrees and higher elevations in the mid 70s.
Dewpoints will be slightly lower than previous days, but still a touch muggy in the low 60s.
The chances for rain will increase this evening and into the overnight as scattered showers transition to areas of widespread rain. Some embedded heavier downpours may locally push rain amounts over an inch, but most areas should end up closer to a half inch of rainfall.
The rain will still be working its way eastward early Wednesday, and showers may linger as long as the late morning for areas near and east of Cayuga Lake.
Clouds will linger for a few hours after the rain ends, but like Monday, sunshine will eventually win out and end the day on a bright note.
Temperatures on Wednesday will start with morning lows in the upper 50s to near 60 degrees, while afternoon highs will top out in just the mid and upper 60s. Northwest winds will blow throughout the day with speeds of 5-10 mph.
Dry for a While
High pressure will build in late Wednesday and stick around through the weekend.
On Thursday, this high will still be to our west, delivering cool air into the region. Morning lows will start in the upper 40s and low 50s while daytime highs will be in the low and mid 60s.
Thursday will likely start and end with sunshine, but scattered to numerous fair weather clouds will be present for much of the day. A few lake effect rain showers early in the day will be possible over northeastern Wayne, northern Cayuga, and into Onondaga counties.
Clear skies and calm winds Thursday night will lead to ideal cooling conditions. Only areas immediately along a lake shore or north of I-90 will stay near or above 50 degrees. Many areas will fall into the mid 40s.
Friday will be a sunny day with few, if any, clouds. Calm winds will cut off the influx of cool air and temperatures will warm to the upper 60s to near 70 degrees Friday afternoon.
Clouds on the very edge of Hurricane Lee may make for an overcast day on Saturday, though some sun may shine through the thin clouds. While no other impacts from Lee are expected in our region, if you have plans in New England, continue to monitor Lee’s progress closely.
Saturday morning will again start with widespread mid and upper 40s. Afternoon highs will be around 70 degrees.
Dry weather will persist into Sunday with a mix of sun and clouds and highs in the low 70s. The morning will be a bit warmer, with lows averaging out to around 50 degrees.
The next chance for rain will come on Monday and Tuesday with some scattered showers. Temperatures should return to the 70s most of next week.
