First Alert Day Wednesday: Rain/snow mix likely for parts of the Midlands

A Winter Weather Advisory is in effect from 2 a.m. to 5 p.m. for the following counties: Fairfield, Kershaw, Lee, Lexington, Newberry, Richland and Saluda.  Snow accumulations are possible.

 A Winter Storm Warning is in effect from 2 a.m. to 5 p.m. Wednesday for the following counties: Chesterfield and Lancaster.  Snow accumulations are likely.

Wednesday is an Alert Day.  Your WIS First Alert Weather Team is tracking a cold front that will likely bring a rain/snow mix for parts of the Midlands Wednesday morning into the afternoon.

First, as we move through your Tuesday night, expect mostly cloudy skies. The clouds will thicken through the overnight, with rain moving in well after midnight. Overnight temperatures will fall from the low 40s into the 30s.

Make sure you check in with your WIS First Alert Weather Team through the day. We're going to keep a close eye on a cold front that will sweep through the area Wednesday. This will be a fast-moving front with limited moisture along it and dry air ahead of it over the Midlands. Still, as the front moves in, we'll likely have enough uplift and cold weather in the atmosphere to see a rain/snow mix early before the precipitation transitions to all snow briefly and begins to dissipate.

On Wednesday, starting around 3 a.m. or so, we'll start seeing rain moving in for parts of the area from west to east. Temperatures will likely be well above freezing first, supporting rain, then sleet. Some snow will start mixing with the rain through mid-morning for the Central Midlands. However, for some of our western and northern counties, the transition to snow will start sooner as our temperatures start to fall.  Snow will continue to move east through the Central Midlands, with areas along the I-95 corridor seeing the least snow, since rain and sleet will continue to be in the mix.  By early-to-mid Wednesday afternoon, we'll start seeing this system move farther east and dissipating.

So, how much snow are we talking about?  Several locations under the Winter Weather Advisory (Fairfield, Kershaw, Lee, Lexington, Newberry, Richland and Saluda) could see anywhere from a dusting up to an inch of snow. For counties like Fairfield, Kershaw, northern Newberry and parts of northern Lee, we'll have to watch closely. We could see some slightly higher amounts of snow in those areas, closer to an inch and possibly more. Areas in Orangeburg, parts of Calhoun, Sumter and Clarendon counties might not see quite as much accumulating snow since rain may hang around a little longer.  However, keep in mind, snowflakes will still mix in with the rain, and there may be a brief period of snow showers or flurries before the event ends, but we're not expecting much snow accumulation in these areas.

Afternoon temperatures will be in the mid and upper 30s.  Low temperatures will be in the teens and 20s. So, any moisture that's still lingering on the ground, bridges and overpasses will likely freeze and will cause some problems. Be careful. We'll continue to keep you updated about the wintry weather moving in.  But remember, if we don't have all of the ingredients coming together Wednesday, parts of the Midlands could miss out on the snow.

Highs will climb into the mid 40s on Thursday under mostly sunny skies. By Friday, we'll see highs in the mid and upper 50s with more sunshine in your forecast.  Then, this weekend, we'll see highs in the low 60s on Saturday before reaching the upper 60s to near 70 by Sunday. Rain moves in for your Monday. High temperatures will be in the 60s.

Tonight: Increasing Clouds. Rain Moves In Late (20%). Overnight temperatures in the 30s and 40s. Winds: S/SW 5 mph.

Wednesday (Alert Day): Mostly Cloudy. Wintry Mix Likely (50%). Some accumulations possible. Highs in the mid and upper 30s. Winds: NW 5-10 mph.

Thursday: Mostly Sunny and Chilly. Highs in the mid 40s. Winds: W 5-10 mph.
