Rain overnight; strong winds by sunrise Thursday

<B>(Wednesday Night January 30, 2013)</B> Moderate to heavy rain will continue overnight. This rain could cause localized flooding. We’ll also see increasing wind, especially after 2 am. During the day Thursday, we could have wind gusts to 55 or 60 mph which has the potential to cause downed trees and power outages.
Our warm, record-breaking weather will come to a quick end tonight.  A cold front is approaching from the west and will do a good job in removing the warm air, and returning us to winter.

While some strong winds are possible in any heavy rain early tonight, widespread strong, potentially damaging winds are most likely late tonight into Thursday morning as colder air rushes into central New York.  Winds will be strongest the farther north you go as these areas will be closet to a departing storm heading into eastern Canada.  Winds could gust to 60 mph from Syracuse north which is strong enough to bring trees and tree limbs down and cause power outages. While the winds will be at their strongest in the morning it will remain rather windy right through Thursday afternoon.

The strong west winds Thursday will usher in colder and colder air. This air will travel across Lake Ontario where it will modify and build into a band of heavier lake effect snow by late morning. The wind direction should stay very consistent out of the west Thursday which will put areas east of Lake Ontario at the greatest risk of heavy snow, especially the Tug Hill Plateau.  By early evening there could be a foot or more of snow in the most persistent snow. We expect mainly flurries with little if any accumulation outside this main area of lake effect Thursday across most of CNY.

We are still keying in on a shift in the wind Thursday night from the west to the northwest as a jet stream disturbance moves through central New York.  That will cause the heavier lake effect snow to shift south.  We think the most likely time for the lake effect to move into the Syracuse area is late at night or close to daybreak Friday.  If this happens, the Friday morning commute could be difficult in and around the Syracuse area.
