Drab Pattern Locked In

A strong jet stream overhead will continue to bring weather systems, large and small, through the Finger Lakes for the next few days.

Clouds, fog, and a few drizzly showers will persist through the morning hours. The fog will especially be thick over higher elevations and may linger in some areas throughout the day. Generally, though, the fog should become thinner and less common by late morning.

On and off spits of rain are likely with a better chance for more numerous showers around and following sunset tonight. None of the rain should be heavy, but additional fog will also be possible.

Surface winds will remain nearly calm again today. Temperatures will only add a few degrees from the morning lows for a high in the upper 30s. A few places may manage to get to 40 degrees. Nighttime temperatures will again settle in the mid 30s.

A south wind will blow at 5-10 mph tomorrow. The wind should help mix the atmosphere, reducing the prevalence of fog and drizzle while also warming temperatures.

It will still be cloudy, though, and on and off showers are expected throughout the day. High temperatures should be in the mid 40s throughout the area, with upper 40s possible from Elmira to Binghamton.

The chances for steady, heavy rain on Saturday are decreasing, but it will still be a rainier day than today or tomorrow. Expect on and off showers with some periods of steadier, mainly light rain. Most areas should push into the low 50s.

Up and Down Pattern

Cold air will slowly seep into the region Saturday night and Sunday. Many places may still be near 40 degrees at the start of the day Sunday. By sunset, though, most areas will be into the 20s.

More rain showers are possible early Sunday, with flurries taking over for the afternoon. None of the snow Sunday looks heavy with no more than a light dusting of accumulation expected.

Sunday will turn breezy, though the strongest winds may hold off until the evening. Daytime gusts will be 20-25 mph while nighttime gusts will be 25-35 mph. These winds will be from the northwest.

Lake effect snow will become organized for a time Sunday night and early Monday before winds start to shift and the lake effect moves north and dissipates. This does not look like a big event, but some areas could see a couple of inches and a messy Monday morning commute.

Temperatures on Monday will be chilly, with morning lows in the teens and afternoon highs in the 20s.

Our next chance for some sunshine will come on Tuesday, though there will probably be plenty of cloud cover, too. Temperatures will warm with southerly winds with highs well into the 30s or even low 40s.

Wednesday also looks mild with highs into the 40s. A late cold front might bring some snow showers and another shot of cold. Highs Thursday may be back into the 20s.

There are hints at a chance for some snow late next week, but there is a lot of time between then and now for things to shift. Generally, though, a slightly cooler pattern looks like it will set up.  Stay tuned.
