Weekend Weather Forecast

A weak cold front is draped across the region Friday morning with some clouds.

The front will sag a bit further south as it dissipates today, leading to a gradual increase in sunshine this afternoon.

North winds will set up behind the front with speeds no higher than 10 mph.

Temperatures will vary across the region this afternoon, ranging from the low and even mid 70s in the valleys of the Southern Tier, to the mid 60s near Lake Ontario. Most areas should end up somewhere around 70 degrees.

Clear skies and calm winds tonight will send temperatures down into the low half of the 40s for most areas. Pockets of 30s and some isolated front will be possible across the Southern Tier, but especially in and around Cortland County.

Saturday will have quite a bit of sunshine and some occasional thin clouds. Winds will be under 5 mph from the northeast.

Temperatures will be similar to today across the southern half of the region, near or above 70 degrees. Northern areas will be a bit warmer today, also coming in around 70 degrees.

Winds will turn to the southeast Saturday night, keeping temperatures in the mid and upper 40s to around 50 degrees.

Sunday will remain quiet and dry. Some areas of clouds may drift through, resulting in mostly cloudy skies sometimes and most sunny skies at others.

South winds will be near or slightly over 10 mph with gusts of 20-25 mph. The wind will help push temperatures into the mid and upper 70s.

Hope for Rain

Weather models continue to increase our chances for rainfall early next week with rain possible both Monday and Tuesday.

While both days should have some rain, there are still subtle details to work out that will be the difference between showers that don’t amount to too much and steadier rain that could have at least a temporary impact on the drought areas.

Monday’s rain is more likely to be showery and is partly dependent on upstream thunderstorm development on Sunday over the Upper Great Lakes and Canada.

While more hit or miss, there could be a few thunderstorms mixed in, which could bring some locally higher rain amounts.

Tuesday is our chance for an area of widespread, steady rain as low pressure passes just south of the region. Since this is still several days away, though, the position and size of the area of rain remain uncertain.

The average rainfall amounts shown on the models at this point are around an inch, but the amounts are highly variable. On the extreme ends, there are models showing amounts both under a quarter inch, or over two inches.

With models now favoring a more southerly path for this low pressure system, our temperatures are not expected to be quite as warm either. Highs in at least the mid 70s are still likely Monday and Tuesday, but some cool air may build in for the middle of next week.

There should be some additional rain chances toward next weekend and beyond thanks to what looks to be a broader pattern shift toward more unsettled and cooler weather as October approaches.
