Scattered light snow chances linger through weekend

Remaining Ad Time Ad - 00:00

MADISON (WKOW) - Light snow continues to fall across the area. And looking ahead... we may be cooling down.

Slick conditions may be possible overnight into the early morning hours on Sunday. Because of this, a few of our counties are under a winter weather advisory until midnight Saturday.

We are on the backside of a low pressure system that brought us a nice blanket of fresh snow as we went into the second half of the week. This low got a little cut off from the jet stream so it's taking its sweet time to move off into the Atlantic. That means we're still under the influence of it.

There's still little pockets of lift moving across southern Wisconsin which means that scattered light snow showers and flurries will be possible throughout Saturday night into the morning hours on Sunday.

The light snow chance will diminish then we'll be left with scattered flurries throughout the rest of Sunday afternoon. Accumulations are going to be light; Saturday night through Sunday morning will be our best to pick up a half an inch of snow while Sunday afternoon onwards, we can expect around a tenth of an inch.

Temperatures are going to be around where we should be for this time of year through the rest of the weekend. Looking ahead into the rest of January, our temperatures might be a bit on the cooler side.

Long range models suggest that the jet stream is going to be sliding its way southward which would allow for cooler air to slide south as well. Another interesting thing is that our precipitation chances will increase too.

The wetter than normal forecast could be contributing to the cooler than normal temperature forecast; with wetter than normal conditions, we can expect more cloud cover as well as more cooler, upper level air being moved closer to the surface.

Cooler than normal, and even wetter than normal, conditions don't mean extremes. Our temperatures may be cooler than normal by a degree or two and our precipitation totals may be .01" more than usual.
