Unsettled and Chilly

A weak area of low pressure will pass through the Finger Lakes today.

Showers will increase this morning as the low spins eastward. A few brief bursts of heavier rain will be possible, along with a small chance for a rumble of thunder or some small hail.

Temperatures will peak in the mid 40s during the midday hours before falling to the upper 30s and low 40s this afternoon.

Those temperatures may be just cold enough for some snow showers to work in, especially over the western half of the region. No snow accumulation is expected.

Precipitation will come to an end this evening and the clouds will break up. Cold air will continue to move in with overnight lows in the upper 20s and low 30s.

The entire region is now considered to be in the Growing Season, so all parts of the Finger Lakes are under a Freeze Warning for the overnight hours.

Tuesday will start with some sun before clouds increase. A few light rain or snow showers may work in for the late afternoon.

High temperatures Tuesday will be in the low and mid 40s. Freeze conditions will develop again Tuesday night as skies clear and temperatures range from the mid 20s in the Southern Tier, to near 30 degrees in urban and coastal areas.

Wednesday will be quite sunny and most places should manage to get to or slightly above 50 degrees. That will still be 15+ degrees below the average high, which is into the upper 60s now.

Major Pattern Change

A warm front will move through the region late Thursday. Clouds will increase after some morning sunshine and rain showers will develop for the late afternoon and evening.

High temperatures on Thursday should reach the low 60s for many areas, signaling a major shift in our weather pattern.

Additional showers will be likely on Friday, but even so, temperatures should push into the low and mid 60s.

Saturday looks quiet and sunny, but another system will roll in for Sunday with periods of rain. Some late day or evening thunderstorms will also be possible.

High temperatures Saturday will be well into the 60s. Sunday may be a couple degrees cooler, but still in the 60s.

Rain may linger into early Monday but will clear out sooner rather than later. Temperatures may get stuck in the upper 50s, depending on how fast the rain moves out.

From there, temperatures will continue to climb. Near to above normal temperatures are expected for most of next week. Hitting 80 degrees is not out of the question at some point.

There are no signs of additional frost, snow, or cold air once we get to Thursday this week.
