Accumulating snow through Tuesday morning, record cold possible

Today's Forecast

…WINTER STORM WARNING in effect until 6:00 am Tuesday for all of WNY…

…WINTER WEATHER ADVISORY (a lesser warning) in effect for McKean, Potter counties 6:00 pm this evening to 7:00 am Tuesday…

The bulk of the snow showers will begin to spread southward through the rest of the afternoon and evening.  The breeze picks up by later today, particularly along the Lake Ontario so this may allow for snow to blow and drift which will limit visibilities and may create travel concerns through this evening. As temperatures continue to drop this evening, snow will start to stick to the roads right away around Lake Ontario. The snow will become moderate to heavy at times through this evening across WNY before tapering off late tonight into tomorrow morning. Total snowfall amounts around Buffalo and areas northward will range between 6-10″ through early tomorrow morning with locally higher amounts toward Wyoming county and near Rochester. There may be a snow, sleet and freezing rain mix towards the state line tonight that will decrease the amount of snowfall accumulation locally, which will keep snowfall amounts between 2-5″ through early Tuesday. Overnight lows range in the teens around the valleys, to the and low-20s near Buffalo.

Aside from the cold, Tuesday should be a little quieter, with just a chance of a few lake effect snow showers. Localized lake snow will start to set up during the afternoon, mainly southwest and northeast of Buffalo.  Some of those lakes snow streamers will continue overnight before winding down during Wednesday morning. Dayitme highs Tuesday afternoon will range in the low to mid-20s!

Record cold minimum temperatures are possible by early Wednesday morning as readings dip into the lower teens. After lake snow showers end Wednesday morning the remainder of the week looks pretty tranquil.  There could be a few mixed showers later Friday.
