Here's the lower part of a vertical temperature profile (RUC 21Z) to show what's happening aloft. For those who can't read the chart, it shows snow falling from a height of 18,000 to 6000ft up. Below 6000 ft there is a warm layer which melts the snowflakes (they're delicate). Below about 3000 ft the raindrops (melted snow) hit a sub-freezing layer for a couple thousand feet. This freezes the raindrops into ice (sleet). The sleet falls through about 1000-2000 ft of above-freezing air, surviving to hit the ground. They're small because much of the sleet is melting off on the way down.
Now currently there is only a thin layer of above freezing temperatures aloft, with the exception of the very lowest layer that reaches the mid 40s. There's a slim chance that if the airmass modifies slightly between 3000-6000 ft and drops closer to freezing that a few snowflakes may make it to the ground, though somewhat melted. I think I MAY have seen 1-2 of these on my drive home, as the spot on my windshield looked more like slushy snow than sleet at least once.
Don't get your hope up (even slightly) that you'll awaken tomorrow to a snow-covered landscape. That airmass aloft should WARM overnight, reducing the chances for sleet or snow. It's cold rain for us tomorrow, but you still COULD see a trace of sleet tomorrow night.
Note: Heights on the chart are very approximate
