Winter & Flood alerts issued for CNY

SYRACUSE, NY (WSYR-TV) Soaking rains give way to a wintry change for all of CNY but is expected to be more impactful over the hills. Details are below…

A Winter Storm Watch has been issued for parts of Central New York, especially across the higher terrain Wednesday afternoon through Thursday due to the potential of an impactful heavy wet snowfall.

This includes Jefferson, Lewis, Oswego and northern Oneida counties.

Complex storm to impact CNY midweek

A developing area of low pressure moves into the Great Lakes tonight, spreading more rain into central New York, but as this storm weakens and transfers its energy to a new storm on Wednesday over the Mid-Atlantic region, it turns colder for us later Wednesday afternoon and night.

It’s a milder night with lows in the low to mid 40s with a steady breeze, but the highs on Wednesday occur during the morning/midday in the low to mid 40s before dropping into the 30s by days end. Winds will also gust at times over 40 mph adding to the raw feel.

Flooding possible for parts of CNY

Rainfall amounts of 2”+ are possible across areas south of Syracuse over the southern Finger Lakes which may trigger poor drainage and small stream flooding, and possibly minor river flooding too, namely the Tioughnioga at Cortland. For this reason, there are Flood Watches up for these areas Wednesday into Thursday.

When does rain change to snow?

As it turns colder rain likely will mix with and change to heavy wet snow at first over the hills between 4 and 8 pm Wednesday and the rest of CNY, including Syracuse experiences that changeover to snow Wednesday evening most likely near or just after sunset.

Commutes potentially impacted by snow

While there is still some uncertainty as to how much snow falls across central New York, we do think the snow could be quite impactful/sloppy on areas roads Wednesday evening around the evening commute across the hills. We believe roads could become at least somewhat slushy/sloppy after sunset Wednesday night into the Thursday morning commute for the rest of CNY.  

Who has the best chance of needing the shovel?

Since temperatures will be marginally cold enough for snow, the snow is going to be very heavy and wet which may cause some tree branches to come down and possibly produce isolated power outages.

We also, are confident that the most significant snowfall accumulations of 3-6” + occur over the higher terrain with a slushy coating to 3” falls for the rest of CNY, including Syracuse Wednesday night through Thursday.

A Winter Storm Watch is issued when significant winter weather is possible but not yet certain. A Flood Watch is also issued when the potential for flooding exists, but it’s not imminent.
