Cold Front This Afternoon

Widespread rain associated with a low pressure system to the northwest will taper off this morning.

As of 7am, there were two main areas of rain. The first fell overnight and is departing the region to the east. A lull in the action is present before a second area of rain, which is moving through the western Finger Lakes and extends south into Pennsylvania.

This second area of rain will track northeast this morning and should be out of the area by the late morning to noontime hours.

A few breaks of sun will be possible after the second area of rain departs. During this time, temperatures should peak in the low 70s. A few mid 70s will be possible if enough sun works out.

During the early afternoon, a cold front will track from west to east across the area. A few showers and possibly a thunderstorm will pop up along the front, mostly east of a Bath-Penn Yan-Geneva line. These should quickly move east into Central New York by 3 or 4 pm. A strong wind gust will be possible with the line, but severe weather is not expected.

Temperatures behind the line will drop back into the 60s with clouds and a few more glimpses of the sun. Winds will remain blustery, coming from the south ahead of the line and from the southwest or west behind the line.

By Saturday morning, temperatures will be in the upper 30s and low 40s. Skies will remain mostly cloudy and a spit of drizzle or some fog will be possible.

Sunshine will gradually increase throughout the day Saturday, but with a northerly breeze, temperatures will only reach the low and mid 50s.

Cold, Wet Weather

A new weather complex will approach from the southwest Saturday night and linger in the region through Tuesday for an extended period of wet, cold weather.

Rain will move into the Finger Lakes after midnight Saturday and should be widespread throughout the region by dawn Sunday. Some of the rain south of I-90 could be heavy and a few higher elevations could even see some snow mix in. Temperatures will be in the upper 30s and low 40s.

The rain may end for a time Sunday afternoon or at least taper to scattered showers. The weather system will split in two, with one low developing to our west over Michigan while a second coastal low takes shape near Long Island.

Rain will move back in Sunday evening and continue into Monday morning. The rain should taper to showers or a steady light drizzle for the afternoon Monday. This will continue through the night and throughout most of Tuesday as well. A few showers may even linger into early Wednesday before dry air finally works in.

Temperatures will have a difficult time reaching even 45 degrees on Sunday. Monday may reach the upper 40s to near 50 degrees for areas west of Seneca Lake, with more low and mid 40s to the east. Tuesday again will be very chilly with highs in the mid 40s.

With plenty of cloud cover and precipitation, overnight temperatures will hover around or just below 40 degrees. Frost is not expected.

Late in the week, temperatures will moderate back towards or even above normal.
