Winter storm watch this afternoon

A storm system will come in from the northwest on Wednesday, bringing light snow to many areas, with the lightest in our southwestern areas. Temperatures are expected to warm above freezing along the coast Tuesday evening.

As a result the National Weather Service has issued a Winter Weather Advisory from 4 am Tuesday to 7 am Wednesday.

We'll see a series of weaker lows move through the Great Lakes.

After a little bit of snow to start the week, we're left with plenty of slick areas on the roads this afternoon. "2-4" of snow accumulation is possible, though some areas could receive an excess of 4" due to heavier snowbands in the system.

The weather service is predicting locally heavy lake effect snow of up to 6 inches, depending on location, resulting in hard travel conditions. Lesser amounts, around 5 inches, are in the forecast for the Southtowns and Genesee county.

WEDNESDAY: Mostly cloudy with snow showers.

Outside of Huron County, just expect a few hit and miss flurries and snow showers today, with not much accumulation. This trend will continue through the evening, then the lake-effect will completely end overnight.

A strong cold front will cross the region early Tuesday.

The big story will be heavy lake effect snow on the backside of this clipper. Erie, Pennsylvania, and southwestern NY, as well as spots south of Lake Ontario, including Rochester and Syracuse, are where model guidance is dumping the heaviest accumulations. The watch began at midnight Monday.

It won't get quite that cold in Upstate New York, but this is likely to be the coldest air we've felt since March - nine months ago.

On Tuesday, temperatures in the Detroit area will continue to decline during the day with a high of 17 and a wind chill as low as minus 6; the low Tuesday will be about 11.
