... Winter Weather Advisory in effect from 10 PM this evening to 8 am EST Wednesday... ... Winter Storm Watch in effect from Wednesday evening through Friday evening...
The National Weather Service in Buffalo has issued a Winter Weather Advisory for a wintry mix... which is in effect from 10 PM this evening to 8 am EST Wednesday. A Winter Storm Watch has also been issued. This Winter Storm Watch is in effect from Wednesday evening through Friday evening.
A wintry mix will bring slippery travel late this evening through early Wednesday. Snow is expected to overspread the western southern tier later this evening. The snow will mix with or change to sleet and freezing rain overnight... finally changing to just plain rain Wednesday morning as temperatures rise above freezing.
Expect 1 to 3 inches of snow accumulation... followed by ice accumulation of a tenth to a quarter of an inch. The greatest amount of ice accumulation is expected in the more sheltered valleys of the interior southern tier where surface temperatures will remain below freezing the longest. Along the Lake Erie shore... temperatures will quickly rise above freezing later tonight with only an inch or less of snow expected and little or no ice accumulation.
By Wednesday evening much colder air moving into the area on the back side of the storm will begin to produce bands of lake effect snow. 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 persist across the area right through Friday. Storm totals by Friday evening will exceed 2 feet in the most persistent lake snow areas.
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.
