PRECAUTIONARY/PREPAREDNESS ACTIONS...

Periods of snow, sleet or freezing rain will result in slippery
roads and limited visibilities. Slow down and use caution while
driving.

Timing the precip

After an initial burst of some snow, precipitation begins as primarily sleet and freezing rain this morning with a light mix expected through the afternoon for most of Western New York. With temps nearing freezing any treated roads should remain in fairly good shape through this afternoon.

However, as the upper storm begins to cross over the area and colder air begins to return an area of moderately heavy snowfall is expected to develop later tonight. The snow will accumulate quite heavlily at times and the the snow looks to linger well into your Monday.

How much Ice and Snow

While ice will be the primary precip type during the day today, overall accums look to be limited on the order of a tenth to a quarter of an inch. Most of the accumulating snow should hold off for Rochester and Western New York until late evening and overnight where it will generally be on the light side for our far western counties including the Buffalo area on the order of 2 to 4 inches. Getting closer to Rochester and the Western Finger Lakes, I think we are looking at a shovelable snowfall with 4 to 6 inches total. Further east into Eastern Monroe/Wayne, Ontario and the Finger Lakes are looking at around 6 to 12 inches and the heaviest snow looks to fall in an area from around Syracuse through the Capital District of the state at around 12 to 18 inches of very heavy, wet snow.
