The National Weather Service in Buffalo has issued a Winter Weather Advisory for a wintry mix... which is in effect from 3 am to noon EST Wednesday. A Winter Storm Watch has also been issued. This Winter Storm Watch is in effect from late Wednesday night through Friday evening.
Snow will overspread the Eastern Lake Ontario region late tonight and continue through Wednesday morning. The snow is expected to mix with or change to sleet and freezing rain Wednesday morning... then change to just plain rain by midday Wednesday.
Expect 3 to 5 inches of snow accumulation... with a tenth of an inch or less of ice accumulation. The greatest snow amounts are expected across the Tug Hill region and the western foothills of the Adirondacks.
By late Wednesday night much colder air moving into the area on the back side of the storm will begin to produce bands of lake effect snow right through Friday. Strong winds combined with the lake effect snow will likely produce very difficult driving with near blizzard conditions at times. The heaviest lake effect snow will start up near Watertown and Carthage and then drift south... targeting the Tug Hill plateau the vast majority of the time. Accumulations through Friday in the most persistent lake snow areas will likely exceed 3 feet.
Precautionary/preparedness actions...
A Winter Weather Advisory is normally issued for a variety of winter weather conditions such as light snow... sleet... and freezing rain. While the weather will be significant... the word advisory implies that severe winter weather is not anticipated.
A Winter Storm Watch means that heavy snow accumulations along with blowing and drifting snow are possible. If you are within the watch area... remain alert to rapidly changing weather conditions.
