Cool and Cloudy
Clouds cleared out of the Finger Lakes region late yesterday and overnight, allowing for a chilly start to the day today.
Most areas are starting out in the 40s, but there are pockets of 30s as well.
There are a few thin clouds in the area, but clouds are increasing upstream and should thicken overhead through the morning. The clouds will then persist for most of the rest of the day.
There may be some thin spots in the clouds that allow some sunshine to sneak through, but overall, it will end up as another cloudy day.
The clouds and a light east wind will keep temperatures in check once again. Highs will be similar to yesterday, ranging through the 60s.
Tonight, clouds should once again dissipate, leaving clear skies and cool temperatures. Widespread 40s with pockets of 30s are expected again.
By Thursday, a meandering low pressure to our west will start to make its way eastward. This means that clouds will thicken yet again Thursday morning and continue into the afternoon. The best chance for breaks of sun will be in the morning.
Winds will be from the southeast on Thursday, giving temperatures a slight nudge upward with highs mostly ranging between 65-70 degrees. The clouds and winds will continue Thursday night, holding overnight temperatures mostly near or above 50 degrees.
The low pressure will pass through on Friday. A few stray showers will be possible, mainly Friday morning across the southern half of the region. Even there, most areas will stay dry. Some sun may work its way out late in the day.
Winds will be light on Friday, and temperatures will push up another couple of degrees for highs around 70 degrees.
Turning Sunny and Warm
Saturday will mark the beginning of a new weather pattern full of sunshine and warm temperatures.
For this last day of September, expect lots of sunshine after a few areas of early morning fog or low clouds. Winds will be calm early, then turning to the north for most of the day.
The north winds will not have much impact on the temperatures, with afternoon highs in the low and mid 70s after morning temperatures start in the low and mid 50s.
Sunday will not be much different, only a little bit warmer. Morning lows will again start out in the 50s while afternoon highs will average out in the mid 70s.
This is about ten degrees above average for the first day of October, but a far cry from the daily record highs, which range from the upper 80s to low 90s across our regional climate sites, mostly set in the 1950s or in 2019.
This weather pattern will continue into next week as well.
Monday will have sun and a few fair weather clouds with highs in the mid 70s.
Tuesday will also reach the mid 70s with only a few thin clouds to interrupt the sunshine.
There is a very small chance for a stray shower on Wednesday, but most areas should just be sunny and dry. Highs should be in the mid and upper 70s and a few places may sneak towards 80 degrees.
Temperatures should remain at least in the mid and upper 70s, if not low 80s, through the end of next week. Dry, sunny weather will persist.
By the following weekend, the range of possibilities on the models begins to increase. By the middle of the following week, almost anything is possible, with simultaneous model data showing everything from highs flirting with 90 to highs in the 40s. The truth will almost certainly be somewhere in the middle.
