Winter Storm Cleon: Major Ice Storms In The South To Snow in The North
 

Winter Storm Cleon, the third named winter storm of the 2013-14 season, has already dumped a swath of locally heavy snow from the Rockies to the Upper Midwest.

In both of those regions, some locations have received over 2 feet of snow.

Now, Cleon will deliver its next wintry punch – a significant snow and ice storm that will stretch from the Southern Plains to the Ohio Valley as we close out the workweek.
Cleon's next chapter begins Thursday as precipitation breaks out along the leading edge of the Arctic air across the Southern Plains.

Precipitation will expand from West Texas across parts of Oklahoma and into the Ozarks and mid-Mississippi Valley Thursday. With surface temperatures plummeting below freezing and relatively warm air a few thousand feet above the ground, much of this will come down as an icy mixture of freezing rain and sleet. Rain will rapidly expand across the Ohio Valley during the day as well, but the cold air will not have arrived there yet.

By Thursday night, precipitation becomes heavier in parts of the Southern Plains, leading to a threat of significant icing in north Texas, southern and eastern Oklahoma, parts of western and northern Arkansas, northwest Tennessee, and western Kentucky. North of those areas, a transition to snow can be expected along much of the I-44 corridor in Oklahoma, southern Missouri, possibly into southern Illinois, Indiana and Ohio.

Friday, as the heavier precipitation swings east and the subfreezing air oozes to the southeast, freezing rain may cause icy conditions to expand into southern Arkansas, northwest Mississippi, west Tennessee, and into a long narrow corridor over or near the Ohio River. Some areas north of the Ohio River will change over to snow as colder air builds in from the north. A little bit of snow or wintry mixed precip will reach Pennsylvania and parts of western and central New York, with widespread rain farther east.
