Multiple phases of hazardous weather this weekend, early next week

Saturday Snow

Snow will move into the Finger Lakes this morning and turn steady by the midday hours. Periods of heavy snow are likely through the afternoon.

Travel conditions will vary based on traffic loads and road treatment.

A general 2-3 inches of accumulation is expected by sunset. A few areas could see slightly more, and a few slightly less.

Saturday Night and Sunday Morning Ice

The snow will begin to transition to sleet and freezing rain shortly after sunset.

The precipitation overnight will be a bit more on and off with a lull possible during the later evening hours.

Any lull should be replaced by another surge of precipitation overnight, much of it falling as freezing rain at least for a couple hours after midnight.

The best chance for precipitation to remain snow will be right along the Lake Ontario shoreline.

Ice amounts will vary, but some higher and mid-elevation locations could see a tenth to a quarter inch of ice by sunrise. This may be enough for some sporadic power outages.

Plain rain will become more common during the predawn and early morning hours on Sunday. However, pockets of freezing rain will continue to be possible throughout the morning, especially in higher elevations and along the rain-snow line north of the Thruway.

Travel will be hazardous to treacherous overnight and into early Sunday morning. Varied travel conditions are likely through Sunday morning as temperatures warm and most areas turn to plain rain.

Late Sunday Cold Front

Most areas should end up seeing plain rain or no precipitation for a good part of Sunday afternoon. Temperatures should even reach the 40s for a couple hours.

A strong cold front will then move through sometime around sunset, rapidly dropping temperatures into the 20s within an hour.

A band of rain will likely accompany the front along with strong wind gusts of 40-50 mph and maybe even a clap of thunder.

This will create flash-freeze conditions where travel quickly becomes hazardous again as icy conditions develop.

West-northwest winds will remain strong, though maybe not quite as strong as with the front itself. Still, a few isolated gusts to 50 mph will be possible during the evening.

Early Week Cold and Wind

Strong winds will continue to pump cold air into the region Sunday night and into Monday.

By Monday morning, temperatures will range through the 10s. However, with the wind chill, it will feel between 0 and -10.

Wind gusts of 35-45 mph with isolated gusts to 50 mph will persist throughout much of the day on Monday. These winds will continue to be from the west-northwest.

Daytime highs will be around 20 degrees, and wind chills will remain near or slightly below zero.

Winds will lessen Monday night into early Tuesday with peak gusts around 30 mph. However, with temperatures dropping into the single digits, early morning wind chills will be -10 to -20.

The wind will pick back up during Tuesday morning and into the afternoon with gusts of 30-40 mph. Afternoon highs will range through the 10s with wind chills of -5 to -15.

Winds will gradually subside Tuesday night as temperatures fall back into the single digits. Wind chills will mostly remain in the -5 to -15 range.

Quieter weather will finally arrive on Wednesday.
