Winter Mix Timeline:

Evening:  Flurries

After 10pm:  Light Mix (sleet/snow north half, light rain/sleet/freezing rain south half)

Overnight: Light mix, slick roads, dusting - 1/2" north half. 

7am Tuesday:  1" or less from Paoli to Seymour, Indiana and north, dusting to 1/2" for areas along and just north and south of I-64, dusting or no accumulations south of Bullitt county.  Most roads will be wet, but watch out for untreated roads, especially to the north, which could be slick and hazardous.

Midday Tuesday:  Any accumulations melting, with above freezing temperatures and a switch to light rain mid-late morning.

Discussion: Our next wintry system will arrive mainly as snow, with rain/freezing rain/sleet southwest of Louisville toward the Western Kentucky Parkway.  Roads could start off slick with light icing possible with pavement temperatures near freezing.  The northern half of the area has the best chance of light accumulations (1" or less, mostly less), with temperatures a bit colder through the atmospheric column north of the river.  No accumulation likely south of E-town, as more rain will mix in. 

Tuesday morning's commute should be mainly wet, with some light snow-covered roads possible north.  Mid-late Tuesday morning temperatures will be just above freezing and the precipitation type will be back to mainly rain.  Any snow accumulations should melt around midday, and certainly by Tuesday afternoon. 

The NAM weather model shows precipitation arriving mostly as light snow, this map below is just after midnight.

The next map here shows the southern half seeing more rain, the northern half in blue with snow around 7am Tuesday.

No more wintry weather for the rest of the workweek.  The weekend looks seasonably cool and mainly dry.
