FORECAST: How much snow TONIGHT Marc?

LOUISVILLE, Ky. (WDRB Fox 41) -- A winter weather advisory is in effect for Jefferson County tonight through tomorrow. And in his 11:30 forecast on Friday, Feb. 4, Fox 41 Meteorologist Marc Weinberg dished on expected snow totals -- and the NEXT chance for snow.

"Looking outside right now, the skies are partly cloudy," he began. "Now the clouds we're dealing with are generally these mid and high clouds.

 Our temperature is 28. We don't have a wind. And we've got a dew point at 20 degrees.

Now this low humidity is going to become a key. Remember: when moisture falls into a dry atmosphere, it evaporates. When moisture evaporates, it actually draws heat out of the atmosphere. So the idea here is this: even if snow or rain is falling, if it's falling from the atmosphere and evaporating, it will help cool things off – and I think that will be a key component tonight."

Weinberg pointed out that snow continues over Arkansas – and it's heading our way.

"By 5 p.m., there's nothing to worry about on your dry home," he said. "It's pretty simple. As we move towards 10 p.m., you start to see this rain-snow mix beginning. Now remember: surface temperatures here are going to be above freezing today, so it will help melt some of this off. As we move towards 3 a.m. we see a widespread mix in light snow – particularly at the river and north.

By 7 a.m. tomorrow morning, we're seeing widespread snow across the northern half of the area, with rain still towards Campbellsville off to the south. By midday, it's transitioned to all snow. Late in the afternoon, there are on-and-off snow showers.

But one thing that is quite clear: in Elizabethtown in the south, the numbers are definitely going to be lower as rain is going to contaminate those totals."

Projected Snow Totals:

Campbellsville, London, Bowling Green: Up to 1 inch.

Louisville, Frankfort, Elizabethtown, Madison, Paoli: 1-3 inches.

"Sunday night into Monday, we could see another system," Weinberg continued. "That one could bring 1-2 (maybe 3) inches to the area. Then it gets really cold behind that system on Tuesday. We've got to watch another system on Wednesday. The track will be critical on this one. One thing that's a guarantee is that it will be very cold behind it."
