Morning rain and snow with lingering spits of mixed precipitation into tonight

Wednesday Morning

What: Occasional rain and snow

Where: Region-wide

Impacts: Minor

A weak low pressure system is passing to our north this morning. Winds are shifting behind the low, allowing some cooler air to move in, at least above the surface. This is causing the rain to gradually turn over to snow.

Most areas should end up seeing at least some snow this morning, and a few briefly heavier bursts will be possible. Accumulations will be limited to a light coating to perhaps locally an inch. Main roads should remain just wet, but a few back roads may get a light coating snow.

Temperatures will remain the low and mid 30s. Winds will become northwesterly with speeds near or slightly over 10 mph.

Wednesday Afternoon and Evening

What: Areas of drizzle, flurries, and fog

Where: Region-wide, especially in higher elevations

Impacts: Minor

As high pressure builds in, much of the low level moisture in the atmosphere, and from the rain and snowmelt, will be trapped near the surface. This will lead to low clouds, spits of drizzle, a few flurries, and areas of fog. Some hilltops may end up in the clouds at times. This should gradually clear out overnight.

Temperatures will continue to hover in the mid 30s with a few places making it into the upper 30s this afternoon. Overnight lows will be in the low and mid 30s.

Thursday

What: Morning clouds, some afternoon sun

Impacts: None

High pressure will pass overhead Thursday afternoon. Low-level moisture will continue to erode away. Morning clouds should even break up for some afternoon sun. Winds will be light, turning from the west in the morning to the south in the afternoon. High temperatures will reach the low and mid 40s with a few pockets of upper 30s in the higher elevations east of Cayuga Lake.

Friday-Saturday

What: Periods of rain showers

Impacts: Minor

On and off periods of rain are expected Friday and Saturday. Friday’s rain in particular looks spotty and potentially brief, with much of the day possibly ending up dry. Saturday, on the flip side, at least has some chance for steadier rain, though that may stay outside of the region.

South winds will be blustery on Friday, especially in the morning when some higher elevations may gust over 40 mph. The south winds will boost high temperatures to the 45-50 degree range.

Winds will briefly turn to the northwest Friday night with lows in the mid 30s. On Saturday, the wind will swing around to the southeast, becoming a bit breezy later on in the afternoon. Highs will reach the mid 40s.

Sunday

What: Breezy, some late snow

Impacts: Minor

A cold front will knock temperatures back on Sunday, with morning temperatures in the mid 30s and afternoon temperatures in the low 30s. Breezy northwest winds will push the colder air in, though the models have backed off some on the wind speeds. Still, gusts over 40 mph may be possible on occasion. Some late snow showers will be possible, but at this time, these do not look very impactful.

Early Next Week

Generally quiet weather is expected for the first half of next week. There may be a few stray lake effect snow showers around early Monday in the far northeastern Finger Lakes. Otherwise, some sun should shine. Temperatures will return to the 30s for highs.

Longer Range

Some precipitation may be possible late next week and next weekend. Temperatures are expected to gradually turn colder beyond next weekend, with the possibility for a chilly second half of January.
