After an early week upturn in temperatures, a cold front tonight will send temperatures down again.
For the daytime hours today, we will be between the system approaching tonight and a weak system that moved through last night. A small bubble of high pressure will track through the region in this small gap.
Much of the area is starting off cloudy this morning, but the clouds should break up somewhat as the morning goes on. Sunshine will poke in and out of lingering clouds before skies turn overcast again this afternoon.
Winds will shift from the northwest this morning to the west-southwest this afternoon as the high passes through. The wind will not be overly strong, with speeds under 10 mph and gusts near or under 20 mph.
Temperatures will be warmest across the Southern Tier, where low 40s are likely. Even Penn Yan and Ithaca could crack 40 degrees if enough sun comes out. Much of the rest of the region will see upper 30s with a few higher elevations in the mid 30s.
Snow will move in from the northwest early this evening and should overspread the area for several hours. After 3 AM, the snow will transition to some areas of poorly organized lake effect. On and off snow showers will continue to drift around the region through Thursday morning, with a few flurries even possible into Thursday afternoon.
Snow accumulations will be just an inch or two for most areas, though some of the lake effect prone higher elevations could see up to three inches.
Temperatures will be down in the mid 10s Thursday morning with highs reaching the low and mid 20s. Northwest winds will gust up to 30 mph during the daytime hours Thursday, making it feel colder and leading to some areas of blowing and drifting snow.
Zero to Sixty
High pressure will build in Thursday night, leading to nearly calm winds and mostly clear skies. These ideal cooling conditions will send temperatures falling, with Friday morning lows ranging from -5 to +5 for most of the region.
From there, though, temperatures will start to make a comeback.
Friday will be a quiet day with a mix of sun and thin clouds. Winds will blow light from the southwest, helping temperatures nose their way back into the low 30s.
The temperature will fall into the 10s early Friday evening, but then rise overnight. Most areas should start Saturday in the 20s. A warm front will move through during the day Saturday, pushing temperatures into the low and mid 40s.
As the front moves through, a spit of rain, or if early enough, a few flurries, will be possible. Mostly, though, precipitation looks scarce.
Temperatures will be on the rise again Saturday night as south winds increase. Temperatures at dawn Sunday should be mostly between 45-50 degrees. Winds will increase further after sunrise with gusts of 35-45 mph.
Even though it will be rather cloudy with scattered showers on Sunday, highs will push into the low and mid 60s. If any breaks of sun come out, a few upper 60s in the Thruway region are not out of the question.
The warm weather will be short-lived, with a cold front dropping south Sunday evening. Temperatures will return to the 30s early next week with a couple waves of low pressure moving along the frontal boundary and possibly resulting in snow for our area.
Temperatures look to stay near or above average for the foreseeable future, though some brief shots of cold will probably still move through from time to time.
