The coldest air of the season so far will plow across the Great Lakes this weekend, triggering lake-effect rain showers and even the first snow of the season.
Now before you get too excited, it will not be cold enough long enough for travel problems because of this.
However, wet snowflakes can mix in with the rain showers over the interior of the northern Lower Peninsula of Michigan and hilly areas in parts of western and northern New York state and western Pennsylvania, according to Rob Miller, Senior Meteorologist.

Daytime highs in these areas Saturday and Sunday will be in the 40s, meaning that part of the day temperatures will be in the 30s, or low enough to allow some wet snow to reach the ground.
"The most likely time for this to happen in northern Michigan is Saturday, while areas farther east this can occur either weekend day," Miller said.
If you are driving around in the rain showers, you may notice the wet snow hitting the windshield at times.
It is not going to snow in the valleys, right along the lake shore areas or in the I-95 corridor... Sorry weather weenies and snow lovers! Most of these places may nary see a rain shower.
Even where it does snow this weekend, an accumulation is not expected.

The siege of chilly weather will bring the most extensive frost or freeze from the Great Lakes to the interior of the mid-Atlantic and New England.
If you have not been hit with a frost in these areas yet, this weekend may bring it.
Be sure to cover those tender flowers and harvest the last of the peppers or tomatoes.
Temperatures are likely to hover above the freezing level over the I-95 cities, but it could get "close" in the colder northern and western suburbs.
