What makes the numbers tricky is the greater chance of bringing in sleet and freezing rain. The best chances for the highest amounts of snow will be south and east of Lexington. If there’s less sleet, we’ll trend higher in that range…more sleet, less. There will likely be sleet mixing in with this, especially as you go southeast within that band. Roughly south of the Bluegrass Parkway northeast along US Highway 68 (again roughly!) will be the begging of a 2 to 5-inch band. Areas north and west of Lexington will be in a general 1 to 3-inch snow, and it should be all snow. So here’s what it boils down to…there will be a sharp gradient between not much snow and another pretty good snow…similar to what happened last Thursday. This also can dramatically lower snow totals, but it leads to its own significant winter weather impacts. With an above freezing mid-layer, the precip type can change to sleet (if the layer is thin), freezing rain (if the layer is thicker and nearer the ground), or just a plain cold Kentucky rain if temperatures sneak into the mid-30s at the surface. For snow, the entire column needs to be below freezing. The warmth is somewhat at the surface, but more importantly about a mile over some of our heads. As we’re getting closer, that does now look like it’ll be part of our equation. That meant a low coming up west of the mountains bringing some warm air with it. But overall, the confidence continues to grow that another significant winter storm is about to arrive in Kentucky.Įarly in the week, we talked about the possibility that the whole storm could be a ‘cutter’. There are more questions regarding precipitation type, especially across the south and southeast. The timing overall has continued to slow. A light glazing of ice up to 0.25" is possible in these locations which could add more hazards to motorists.(LEX 18) - We continue to track what looks to be a widespread impactful storm this MLK weekend. This puts a thin layer of ice on cold surfaces including bridges and overpasses. As the snow falls, it melts into rain, but refreezes as it touches the freezing surface. The initial swath of moisture will include this intrusion of warm air above the surface. Warm air trapped between freezing air above and at the surface will aid in the development of freezing rain. Snow will continue overnight into Monday morning with several additional waves of snow continuing through the day Monday. As we continue into the latter part of the day Sunday, precipitation will begin to change over to all snow as the cold air behind this storm system works in. This swath of snow, sleet, freezing rain, and cold rain will continue to push north through the middle and late morning hours. Timing will have multiple types of precipitation bubbling north into the state early Sunday morning. The low will drop southwest of us today and tonight bringing the bulk of the precipitation with it. Temperatures will suffer and remain around or a little above freezing. Clouds will hang tough with a little clearing at times. Most of Saturday will be quiet in the weather story. All types of precipitation with varying amounts are expected and things will change rapidly with this storm as Saturday progresses. The warning is in effect from Sunday 11:00 am until Monday 3:00 am.Ī complex winter system is on the agenda for Kentucky this weekend. THE LATEST: The National Weather Service has issued a WINTER STORM WARNING in effect for several central Kentucky counties, including Fayette, Bourbon, Nicholas, Jessamine and Clark.
