An area of high pressure over eastern Canada is supplying some chilly air to the region on a light north wind.
However, a quick moving weather system racing towards the Great Lakes will push a warm front through tonight.
The northerly flow across Lake Ontario has widespread low cloudiness in place this morning, though there are thin spots and a few breaks in the clouds. These clouds will slowly dissipate, but new clouds ahead of the warm front are already beginning to move into the area.
Therefore, while there will be thin spots and some glimpses of sunshine, overall it will be a cloudy day today.
High temperatures will struggle to reach 40 degrees for much of the region, and many mid to higher elevations will stick to the 30s. The warmest temperatures will be found in the broad valleys of the Southern Tier, where low to mid 40s are expected.
As the warm front approaches late this afternoon and early this evening, a narrow band of precipitation will track across the area, especially across roughly the northwestern half of the area. This precipitation is expected to be light and brief between 5 and 9 PM.
Most of what falls should be rain, but some sleet or a few snowflakes may mix in. This should not be enough to cause any travel concerns. The rest of the evening should be mostly dry.
Overnight and especially into early Thursday morning, rain showers will be more widespread. There is no concern for wintry precipitation with these since temperatures will rise overnight and should be in the 40s and locally even low 50s by sunrise Thursday morning.
The rain should not stick around too long Thursday morning with a mostly dry, mild afternoon expected. A few breaks of sun may even be possible. Temperatures will top out in the mid 50s.
This rapid warm up will be the result of some more blustery winds. Southeast winds will pick up this evening, peaking from the south at speeds around 15 mph after midnight. Higher elevations, in particular, may see gusts over 35 mph overnight.
The wind will become more westerly on Thursday with speeds of 10-15 mph and gusts of 25-35 mph, the strongest of which will be found in areas west of Keuka Lake.
Weekend Weather Forecast
The wind will remain breezy on Friday with speeds and gusts similar to Thursday. A slight north of west component will be added to the wind direction.
Temperatures will decrease with highs mainly in the upper 40s, though some localized areas will hit 50 degrees. Clouds should be plentiful throughout the day, but some breaks of sun will still be possible.
By Saturday, winds will become more northwesterly, which may bring some rain showers off Lake Ontario into the area. It should not be a washout or a period of heavy rain, but more hit or miss light showers, especially in the morning.
Saturday’s high temperatures will slide back a bit, mostly in the mid 40s. Saturday night will be colder than previous nights, with lows in the low 30s and upper 20s.
» Don’t forget! On Saturday, I will be selling my calendars live and in person at the Groton Craft Show, held from 9 AM to 3 PM at the Jr./Sr. High School. My booth will be in the cafeteria. I’d love to meet you and chat for a while, so be sure to stop by! And, of course, you can get the calendar online or at one of my other in person events if you are not in the area.

Sunday will have sun and clouds with highs in the low 40s and nighttime temperatures in the mid and upper 20s.
The weather may become a bit more active early next week, with temperatures starting to increase again with a few showers here and there. By the middle and end of next week, temperatures should be above average with only low chances for precipitation.
Winds should be relatively light through the weekend and into next week, with most days having gusts topping out at or under 20 mph.
