Weekend Weather Forecast

Friday is off to a very mild start with many areas already near or into the 50s.

However, a cold front will first bring rain this afternoon and evening, and then cooler air overnight, ushering in a new weather pattern.

The first rain should begin to move in from the west during the late morning or midday hours. At first, the rain may be scattered, but it should quickly become widespread through the early and mid afternoon.

By 3 or 4 PM, the rain should be steadily falling throughout the entire region. This will continue into the early evening. On the backside of the steady rain, there may be a narrow line of particularly heavy rain and gusty winds. This will mark the passing of the cold front.

Behind the front, widespread showers will continue for several more hours, only gradually tapering off near and after midnight. A few spits of lake rain and flurries will linger overnight and into early Saturday morning.

Temperatures will rise into the upper 50s and low 60s ahead of the rain, despite plenty of cloud cover. South winds around 10 mph will help this warming take place. It will remain mild this evening, even as winds turn to the northwest. By midnight, temperatures should still be in the mid 40s.

Cooling will accelerate after midnight, and morning lows Saturday should be down into the low and mid 30s.

Saturday will have north-northwest winds around 10 mph. Morning clouds will give way to some afternoon sunshine, and temperatures will top out in the low to mid 40s.

Partly cloudy skies are expected Saturday night with temperatures falling to the low 30s. Sunday will have clouds, some scattered showers, and perhaps a few glimpses of sunshine. Highs will be in the mid 40s.

Northwest winds will be blustery for a time on Sunday. Wind speeds will approach 15 mph, especially in the late morning and early afternoon. Gusts will top out at 30-35 mph.

Thanksgiving Week Weather

Light north winds will set up for Monday, keeping temperatures down despite a fair bit of sunshine.

Morning lows will start out well into the 20s and afternoon highs will mainly stick to the mid and upper 30s. A few of the typically warmer valleys in the Southern Tier may sneak above 40 degrees.

Clouds will increase later Monday ahead of the next weather maker. This system will arrive later Tuesday with rain and wind. There are still questions as to how heavy the rain will end up and how strong the winds will blow, but it is a potent enough system to keep an eye on.

At this time, the bulk of the active weather looks like it would occur Tuesday night.

Temperatures ahead of this system may bounce back to the mid and upper 40s on Tuesday. Falling temperatures are then expected on Wednesday, with morning highs in the 40s falling to afternoon lows in the 30s.

Behind Tuesday’s system, there are hints that the lake effect snow machine may get going, especially east and northeast of Lake Erie and Lake Ontario. Typically, this pattern does not produce much snow in the immediate Finger Lakes area, but with Thanksgiving travel ongoing, those heading north or west should keep an eye on the forecast.

Temperatures will likely stay in the 30s for highs on Thanksgiving, Black Friday, and into the weekend. Looking even further out, this may be the pattern we remain in through the end of November.
