LATEST ON THE STORM
Winter Storm WARNING for Chemung, Steuben, Yates, Schuyler & Tompkins Counties. This means significant winter weather is likely in the these counties.
Winter Weather ADVISORY for Tioga County, NY, Tioga County, PA & Potter County, PA. A wintry mixture of rain, sleet, freezing rain and snow is likely for these counties. While there will be some accumulating snow, it appears that it'll occur later today and tonight for these counties. Overall snowfall amount for these counties will be lower with a mix lasting longer.
TIMELINE: Through the morning...it'll be rain showers with little impact on roadways, however, it could be a little slick. It appears a batch of steady rain will arrive midday and that is when rain showers will mix with snow and sleet. It'll eventually swtich over to all snow during the mid-to-late afternoon. During the afternoon, falling temperatures will be common. As the temperatures drops to Near 32° roadways will likely become slick. Once readings drop below 32° snow will begin sticking to everything. Snow will stick to trees, cars, grassy surfaces, roadways, sidewalks and driveways. There is a potential for steady snow during the evening rush. Wind speeds will begin to increase later today, too. Sustained wind speeds will likely be in the 15-25mph range with wind gusts in excess of 30mph! Snow will begin to change from a wet snow to more of a powdery snow and with windy weather, expect blowing and drifting snow to evolve. In addition to northerly winds driving colder air into the region, expect a flash freeze as any water on surfaces from the mild weather the past few days rapidly freezes with falling temperatures.
Snow will persist through the evening with some occasionally moderate to heavy bursts of snow. Snow will gradually ease a bit as we go through the night. By the time the storm is over, 4-8" will likely be on the ground for sections of the Twin Tiers. Snow totals will be higher over the Finger Lakes with 8-12" likely.
Strong northerly wind speeds through the night will not only cause blowing and drifitng snow, it'll also cause wind chill readings to fall below zero late tonight and Thursday morning.
While the models have come into better agreement, it continues to be a VERY tricky forecast with respect to snow, mix and snowfall amounts. A small shift in the track of this storm could change our thinking. We will keep you posted.
