Cold Front Moves Through

High pressure is over the Finger Lakes this morning as a low pressure system lifts northeast through the Upper Midwest.

Underneath the high pressure, there are still some areas of fog around this morning while other areas will start with some sun.

Our window for sunshine will persist through much of the morning before some thin clouds out ahead of the low pressure start to move in. These should thicken up through the afternoon and a few rain showers may arrive before the sun sets.

The extra sunshine this morning and a strengthening southerly wind will push temperatures into the mid and upper 40s this afternoon.

Wind gusts will reach 25-30 mph late this afternoon and continue through the night. Temperatures may initially dip into the low 40s but will rise again after midnight into the upper 40s and low 50s.

During the overnight, there will be periods of scattered rain showers. These will continue into early Friday morning as the cold front associated with the low pressure moves through the Finger Lakes.

As the front passes, winds will turn to the northwest and increase. Gusts by midday Friday will be between 30-40 mph. Temperatures will take a quick drop into the 35-40 degree range during the morning and hover there until the late afternoon.

Rain showers will turn to on and off flurries during the morning. A few brief bursts will be possible, especially southeast of Lake Ontario, into the afternoon. No more than a coating of snow should accumulate and most areas will see no accumulation.

Winds will gradually die off and become calm Friday night and skies will clear outside of some lake effect clouds across the far northeaster portions of the region.

Temperatures will therefore start the weekend in the low and mid 20s for most with Saturday morning lows near 30 degrees where lake effect clouds linger.

Next Two Weather Systems

Saturday morning will start out with sunshine, but, like today, thin clouds will move in and thicken up over the course of the day. High temperatures will top out around 40 degrees.

The next system will approach from the south Saturday evening. Confidence is increasing that this system will impact us, albeit rather minorly.

A light mix of snow and some pockets of sleet will move in well after sunset. A few pockets of freezing rain will also be possible, especially over the Southern Tier.

By early Sunday morning, the heavier precipitation should be well to the east and the Finger Lakes will be left with a few snow showers, possibly mixing with some rain.

Untreated roads early Sunday may be a bit slick, but generally travel conditions are not expected to be too detrimental with temperatures near or above freezing from the get-go.

Sunday will remain cloudy with spits of rain and snow throughout the day. Temperatures will not rise much, topping out in the mid and upper 30s.

Temperatures will go on a warming trend Monday and Tuesday with highs in the 40s and even low 50s.

The next system to watch will move on Tuesday night or Wednesday. After starting as rain, wintry precipitation will become possible. At this early juncture, the impacts on Thanksgiving Travel do not seem to be too concerning, but there is a lot of time to pass to keep an eye on this.

Thanksgiving itself will likely have a few morning snow showers, a bit of afternoon sun, blustery winds, and highs in the 30s.
