Cold air will move into the Finger Lakes in waves over the coming days.
While some of the cold has already arrived, the really chilly air is still lurking off to our northwest. This will start to make its appearance tonight as another cold front moves through.
As this front moves through, showers will become more numerous this evening. Until then, however, the daytime hours on Friday should be fairly quiet, with only a couple of isolated showers and even some sunshine.
Temperatures should reach the mid 50s this afternoon, though some of the normally cooler surrounding areas south and east of the immediate Finger Lakes area will only reach the low 50s.
Cold air will intensify overnight, with temperatures in the 30s by Saturday morning. Some patchy frost may be possible. Temperatures will only rise to the mid 40s Saturday afternoon, with scattered showers, mostly early in the morning and late in the day.
The cold will continue to deepen, with morning lows ranging from near 30 degrees to the mid 30s. More showers, and maybe some snowflakes over the higher elevations, will be possible. Highs on Sunday will struggle to get much past 40 degrees.
Winter is not settling in though. Skies will clear Sunday night, leading to a widespread freeze, but temperatures will start to rise beyond that. In fact, before the month closes out, we should have numerous opportunities for above normal temperatures well into the 60s.
