Significant Late Week Snow And Ice Texas To Ohio
Wednesday morning, December 4, 2013
* Push of arctic air sparks a period of ice and significant snow from the Texas Panhandle into Oklahoma, Arkansas, the Middle Mississippi Valley into the Ohio Valley late Thursday into Saturday morning.
* Potential for 1/4″ glaze ice amounts from near Little Rock to Memphis and Bowling Green Thursday night into early Saturday – capable of significant travel challenges and downed trees, power lines. Power outages are possible as this storm ripples across the Mid South into the Ohio Valley.
* No major snow/ice problems for major east coast cities into the weekend. A cold rain is likely New York to D.C. Friday into Saturday.
A Stripe of Snow & Ice. In-house models show the greatest potential for plowable snows and ice Thursday into Saturday from Oklahoma City into northern Arkansas and the Mid South, with significant snow into Ohio, western Pennsylvania and upstate New York.
Snowfall Potential. Here are a few select city amounts, the latest snowfall predictions, showing the most concern from the Texas Panhandle into western Kentucky and Ohio. Friday may be the most problematic day for travel (land and air).
Thursday Ice Risk. The red-shaded area shows a high risk of .25″ of glaze ice or more, capable of disrupting travel and triggering power outages – the greatest concern over southeast Oklahoma and western/northwestern Arkansas.
Friday Ice Potential. By Friday surface temperatures dip below 32F in the Memphis area, possibly Nashville, creating freezing rain (glaze ice) problems. Moderate to heavy snow is likely just north and west of the regions of heaviest ice, brushing Louisville, Cincinnati and Columbus.
Summary: One of the coldest outbreaks in a decade will push into the USA later this week, preceded by a band of snow and ice pushing unusually far south. Facilities and staff from Little Rock and Hot Springs to Memphis, Nashville, Louisville and Columbus should monitor forecasts – watches and warnings are inevitable, and the risk of winter-related impacts to operations will be high late Thursday into Saturday morning.
