The start of this week will be fairly pleasant across the Finger Lakes.
A pair of high pressure systems, one to our south and another to our north, will team up to bring some sunny weather to the region on Monday and Tuesday.
On Monday, the southern high pressure will be dominate. A west, southwest wind early in the day will help boost temperatures into the low and mid 50s. Areas further south and west will be warmer. This afternoon, an east wind will start to set up as the Canadian high strengthens. This will keep the eastern Finger Lakes a touch cooler than the west.
Temperatures tonight will be cold, with clear skies and calm winds. Some areas may even reach the 20s, with low and mid 30s elsewhere.
On Tuesday, the eastern Finger Lakes will struggle to reach 50 degrees thanks to the east wind. Areas further west will be a touch cooler as well, with highs mostly in the low 50s. It will remain sunny until late in the afternoon, when clouds will start to increase.
This increase in clouds will be ahead of a storm system that will be strengthening across the middle of the country. Wednesday will be mostly cloudy, but with a gusty south wind. Temperatures should respond by reaching the mid and upper 50s. Temperatures will only fall a little Wednesday night, and could push 60 degrees early Thursday.
Colder air will start to work in late Thursday behind a cold front. Unlike our previous shots of cold air, which only last a day or two, this storm system will usher in a new regime where cold reigns supreme. A white Thanksgiving may even be a possibility.
