Temperatures Trend Upwards
After a couple of days of seasonable temperatures, the Finger Lakes is heading back into another warming trend that will peak on Sunday.
An area of high pressure over far eastern Canada will slowly pull away from the region. Already, the return flow on the back side of this high has set up over the Finger Lakes with south or southeast winds.
A south-southeast wind often brings some extra atmospheric moisture to the Finger Lakes from the Atlantic Ocean. Combined with an existing area of slightly higher moisture over the Great Lakes, we are set up for more clouds than sun today.
Still, some occasional breaks of sun should be expected from time to time. The chances for rain will be minimal, though a stray shower cannot totally be ruled out, especially over the western Finger Lakes.
Temperatures will be a bit warmer today than they were yesterday. Most areas will see at least the mid 60s. If enough sun breaks out, upper 60s are certainly possible as well.
Saturday should be sunnier after a couple of scattered morning showers that move through in response to a stronger push of warm air. This will be in response to a developing storm system over the Upper Great Lakes.
Highs on Saturday should push into the low and mid 70s. South winds will strengthen Saturday night, keeping overnight temperatures in the 60s despite clear skies.
Sunday will be the peak of the warmth, with highs pushing into the upper 70s. Skies will be sunny to start, but clouds should increase late in the day.
Strong Winds, Rain Late Sunday
The center of the storm system over the Great Lakes will pass by to the north on Sunday.
As the storm tracks east, it will send a powerful cold front through the Finger Lakes late Sunday.
Out ahead of this front, strong winds will develop, especially over higher elevations and for areas between Rochester and Buffalo.
Wind gusts of 35-45 mph are likely all across the region, but the windiest spots could see gusts as high as 50 mph. This could be strong enough for some sporadic power outages.
The wind will be strong all of Sunday but will be strongest in the late afternoon as the front plows through.
Along with the wind, a band of rain, some heavy, will move through the region with many areas seeing around a half-inch of rain.
Temperatures Crash Behind Front
Behind the cold front, temperatures will rapidly fall. After nearly pushing 80 degrees on Sunday, temperatures Monday will struggle to get much past 50 degrees.
The weather Monday will start cloudy but should see a gradual increase in sunshine. Winds will remain gusty, but will not be nearly as strong as on Sunday with gusts of 25-35 mph.
Clearing skies Monday night will lead to a cold Tuesday morning.
Frost and possibly Freeze alerts will likely be needed for much of the region with morning lows Tuesday in the low and mid 30s. As usual, the coldest areas will be across the Southern Tier and into Central New York, but even the central Finger Lakes may dip into the 30s.
Sunny skies Tuesday and Wednesday will help temperatures to rebound slowly, with highs in the upper 50s Tuesday and well into the 60s Wednesday.
Most of next week is looking dry and sunny.
