(From the National Weather Service.)

Here’s an overview of the storm’s forecast timing and how much snow and ice you can expect.

Forecast Timing

Tuesday-Tuesday Night

Snowfall from this storm will spread out of the southern Rockies into western parts of Oklahoma and Texas during the day on Tuesday.

Current Radar

Tuesday night, widespread snow could impact areas from northern Texas and Oklahoma to Arkansas and Missouri. This includes Dallas-Fort Worth, Little Rock, Oklahoma City, Tulsa and Springfield, Missouri.

Freezing rain and sleet will break out from central and eastern parts of Texas into northwest Louisiana. This ice will make travel conditions dangerous and could also damage trees and power lines.

Tuesday Night’s Forecast

Wednesday-Wednesday Night

Snow will continue to spread northeastward from out of Oklahoma and northern Texas into parts of Arkansas, Missouri, western Tennessee and the Ohio Valley on Wednesday.

Freezing rain and sleet could hamper travel from central and eastern Texas into portions of northern and western Louisiana and the lower Mississippi Valley. It’s possible that ice accumulations might be heavy enough to cause tree damage and power outages in some areas.

Wednesday night, snow could expand farther east through the Ohio Valley, central Appalachians and mid-Atlantic, including Washington, D.C. and Baltimore. Significant icing might develop to the east of the Appalachians as far south as south-central and southwest Virginia and north-central and western North Carolina.

Wednesday’s Forecast

Thursday-Thursday Night

This storm is likely to spread its reach across most of the Northeast on Thursday and Thursday night.

Much of the Interstate 95 corridor, including Boston, New York City, Philadelphia and Washington, D.C., will start out with snowfall before transitioning to a wintry mix or even rain. How quickly that transition occurs will determine snowfall amounts, but at least some accumulation is expected.

Icing may continue for a time as far south as south-central and southwest Virginia and northern North Carolina until a change to rain occurs in some areas.

Snowfall will also continue on the backside of this system from parts of the Great Lakes into the Ohio and lower Mississippi valleys. That snow could be heavy in some of these areas.

The storm will begin to exit the Northeast on Friday, but snow might linger across upstate New York, northern New England and parts of the Great Lakes and Appalachians.

Thursday’s Forecast

How Much Snow and Ice?

There is the potential for Viola to produce several inches of snowfall from portions of Oklahoma and northern Texas eastward into Arkansas and the lower Mississippi and Ohio valleys. Totals could be 5 inches or more for areas shaded purple in the map below, including Oklahoma City, Little Rock and Memphis.

Parts of the Northeast Interstate 95 corridor from Boston to New York City, Philadelphia and Washington, D.C. could start with several inches of snowfall late Wednesday or Thursday and then transition to a wintry mix and possibly rain. How quickly that transition occurs will determine snowfall amounts in these areas closer to the coast, but at least a few inches of accumulation is expected.

Heavier snowfall totals are more likely across interior areas of the Northeast, where amounts of 6 inches or more are possible in a broad area.

Snowfall Outlook

There is the potential for significant accumulations of freezing rain on trees, power lines and other surfaces in the South beginning Tuesday night or Wednesday.

The threat of icing is highest right now from central and eastern parts of Texas into portions of the lower Mississippi Valley.

All of these locations could have enough ice to slicken untreated roads and make travel dangerous.

Ice could be heavy enough to damage trees and knock out power as well, especially in areas shaded darker purple on the map below.

Additional icing will occur late Wednesday into Thursday in parts of the East, particularly in southern and central Virginia and northern and western North Carolina. The ice in these areas could slicken travel and also contribute to tree damage and power outages.
