A short-lived Saturday snowfall
***9:30 AM Update***
For many of us this is turning into a no-lived snowfall. Low level dry air prevented a swath of snow in the middle atmosphere from reaching the ground in much of our area. As a result, the quick light accumulation that was expected hasn't materialized so far. While more precipitation will move in this afternoon, low level warming will mean that will take the form of a snow/rain mix with little in the way of accumulation as temperatures rise through the 30s. Many of us will remain as a cold rain into tonight. The main areas of wintry impact now appear to be over western Ohio and closer to Route 50/north...as well as east of US 19 in West Virginia where snow accumulation is still expected, along with some sleet/freezing rain at times tonight. The rest of us may see a little snow at times but accumulations would be limited to a coating at best.
Winter made a comeback this week with arctic cold and some snow squalls following a cold front Tuesday night. While we felt the chill in the valleys we didnt see much snow out of the squalls....that was confined to the higher elevations where Snowshoe and Canaan Valley picked up around a foot of fresh powder.
We've got another chance for a little snow but if you sleep in Saturday you might miss it. A low pressure system over Oklahoma this Friday night will track east into Tennessee by tomorrow. It's producing an impressive heavy snow in Missouri and southern Illinois...but some of that moisture will weaken approaching us toward dawn. More signifcantly for us...the warm wedge will make an appearance, with southerly winds drawing in milder air and changing our snow to rain by the second half of tomorrow.
First things first...we'll get some snow breaking out around or just before dawn in most locations. With the ground cold from our recent snap, I expect snow to stick pretty quickly to the roads. Most of us will see between a coating to perhaps 2"...not much but again with the cold ground it will be a bit tricky for travel. Mountaineer fans heading up I-79 for the Noon tip will want to leave at least 30 minutes early. That warm wedge will result in temperatures rising above freezing toward noon and the afternoon, starting south and then working north. That means a change to rain and what snow you get in the morning will be gone by the end of the day if not earlier...so enjoy it while you can. Herd fans may be battling a chilly rain heading to the 7 p.m. game but roads should just be wet.
Snow will hang on longer in SE Ohio with about 2-4" of snow possible although even there some melting will occur Saturday night. Areas east of US 19 in WV will remain mostly snow (perhaps a little sleet/freezing rain mixed in Saturday night) and 3-6"+ snow will total from Saturday to Sunday. More great news for the ski resorts. Travel toward Columbus and Cincinnati will be trickier as heavier snow falls there and roads will likely be messy all day.
Rain will change back to some snow Sunday but with marginal temperatures it's unclear if there's any additional accumulation to result. Roads could get slippery again in spots Sunday morning but we'll keep you updated. Another piece of upper level energy may bring some more light snow showers through here Sunday night but they'll exit Monday and next week features a gradual warming trend with little in the way of wintry precipitation at this point.
