Weather forecast: Clouds move in overnight

Weather Forecasts

Detailed forecast for Rochester, the Lakeshore & Finger Lakes


We have been able to enjoy ample sunshine this afternoon as temperatures reached the 40° for the first time since last Sunday. Clouds will slowly increase overnight as a large storm system off the Atlantic coast moves northward. This storm system will have some very outer bands on the western side of the storm that will try hard to stretch into New York but will likely only make it into the eastern half of the state and clouds will dominate for most of the day. Temperatures will not move much, holding in the 30s for most of the day and topping out at about 40°.

We are holding onto a small amount of snow in Western New York.

We are entering a bit of a stagnant pattern to start the work week. A large trough of cold air will situate itself over the region and bring below average temperatures that will sustain through Wednesday. Day-by-day temperatures will start in the low 30s and finish around 40°. The wind direction will shift a bit Tuesday that will make way for a few scattered lake-effect snow showers, but the focus will be south and east of Rochester.
Brief high pressure comes in Wednesday and this should allow for a bit of sunshine. It makes way for some warmer air to start working in ahead of our next weather maker that arrives on Thursday. Expect Thursday to be the first “average” day of the week for temperatures as highs climb into the upper 40s. This will mark the approach of a storm system that brings rain showers overnight heading into Friday.
The storm system strengthens and brings windy conditions heading into Friday. There will eventually be a changeover to snow showers on Friday that could bring some accumulations as well as a continued breezy day to finish the work week. As for now Saturday looks like there could be some trailing lake-effect snow after the storm system with cooler air in place. Some lake-effect snow showers from a different setup could arrive by Sunday.
