A damaging ice storm is possible from Oklahoma to the Ohio Valley this week as two rounds of snow add to the recent snow fatigue in parts of the Midwest and East.

Wintry weather will develop in a classic February battleground zone between and milder air in the South.

Jet stream disturbances tracking from west-to-east through this area will provide lift in the atmosphere, resulting in bouts of snow, ice and rain.

The National Weather Service has issued various winter weather alerts from the Southern Plains to New England, from winter weather advisories for lighter precipitation, to winter storm watches, where ice and/or snow accumulations could be more significant.

This won't happen with one large, slow-moving storm, such as last week.

It will happen in two rounds. Let's begin with the first round.

System #1: Early Week

The first quick-moving system already produced major impacts Monday morning.

Freezing drizzle and light freezing rain laid down a glaze of ice on roads in Kansas, Oklahoma and southwest Missouri, leading to . Up to one quarter-inch of ice accumulation was reported in Bartlesville, Oklahoma, early Monday.

Current Radar

This system will quickly sweep through the Midwest and Ohio Valley Monday night, then into the Northeast on Tuesday.

While most of this precipitation should fall as light snow, some lingering freezing drizzle is possible from Oklahoma to the Ohio Valley through Tuesday morning.

During the daytime on Tuesday, much of the snow will be in areas from New England southward to New York, northern New Jersey and Pennsylvania. A mix of rain and snow is possible as you head farther south along the Interstate 95 corridor, from near New York City into southeast Pennsylvania.

Snowfall totals from this system will generally range from a dusting to 3 inches in most spots, as depicted in the forecast below. Areas from the Poconos in Pennsylvania and the Catskills of New York to the Berkshires in Massachusetts might see slightly higher totals.

Snowfall Forecast Through Tuesday

System #2: Mid to Late Week

The second wintry system will occur over a longer duration mid to late week and will pack a greater threat of ice.

Tuesday Night-Wednesday

Freezing rain and sleet may develop Tuesday night through Wednesday from Oklahoma eastward into the Ozarks and Ohio Valley. At least light snowfall may spread from parts of northern and central Missouri to the mid-Atlantic.

Scattered showers and thunderstorms could dampen the Deep South.

Wednesday's Forecast

Wednesday Night-Thursday

Wednesday night into Thursday there could be a narrow zone of freezing rain and sleet from north-central Texas eastward to parts of Arkansas, northwest Tennessee, Kentucky, West Virginia and Virginia.

Snow might stretch from the Midwest to the mid-Atlantic and the New York Tri-state area. Snowfall from this system may linger into Friday in the Northeast.

Widespread rain and some thunderstorms are possible in a broad area of the South.

Thursday's Forecast

How Much Ice and Snow?

Areas from the Ozarks into the Ohio Valley have the greatest chance of seeing significant accumulations of ice.

Parts of this zone could pick up enough ice accumulation not simply just coating untreated roads, but also enough to snap tree limbs and trigger power outages.

The areas with the greatest threat for these damaging ice accumulations are shown in the darkest contour on the map below.

Probability of 0.10" or Greater Ice Accumulation

(NOAA)

It's still a bit too early for specific details, but snowfall accumulations from this second system will be light to moderate in most locations from the Midwest eastward to portions of the mid-Atlantic and Northeast.

There is uncertainty in how far south there will be significant accumulating snow in the mid-Atlantic, including the Washington, D.C metro area.
