Snow, ice and heavy rain loom for storm-weary eastern US later this week

AccuWeather logo AccuWeather 11/12/2018 alex.sosnowski

A storm with snow, ice and rain will bring travel disruptions from the Midwest and southern United States to the Northeast spanning Wednesday night to Friday.

Motorists and airline passengers in much of the eastern U.S. should be prepared for more delays as a second winterlike storm for this week runs its course.

A weather pattern more typical of late December or early January will continue across much of the eastern U.S. this week. The pattern not only features much colder-than-average conditions for the middle of November, but is also packed with winter-style storms.

Following the most recent storm with snow, ice and rain from Monday to Tuesday night, a second storm will take a similar path from the Gulf of Mexico to southeastern Canada during the middle to latter part of this week.

This new storm will have colder air on both its front and back sides, when compared to the early week storm.

Rain, wind and thunderstorms to bring share of travel delays

Along much of the Atlantic seaboard, the storm will bring drenching rain. Enough rain may fall to bring a renewed risk of flash and urban flooding.

The rain, combined with gusty winds and a low cloud ceiling, can put airlines behind schedule and force motorists to slow down for safety concerns.

From the Florida Peninsula to eastern North Carolina, there may be locally severe thunderstorms with strong wind gusts.

In the Northeast, winds may kick up enough on the front side of the storm to cause a several-hour period of above-normal tides and minor coastal flooding.

Potential for snow, ice in more places with this storm

"With the lower temperatures initially and at the end in mind, the new storm will bring more snow and ice to more places in the South, Midwest and Northeast than the first storm of the week," according to AccuWeather Senior Meteorologist Dave Dombek.

The setup will allow an icy mix to spread northward in a zone from western North Carolina to part of western Virginia, northeastern West Virginia, central and western Maryland and a large part of central and southern Pennsylvania spanning Wednesday night to Thursday.

During Thursday night to Friday, this icy mix will also contain more snow across parts of northern Pennsylvania, part of northern New Jersey, western and northern New York state and central and northern New England.

Along the Interstate 95 corridor from Washington, D.C. to Boston, the bulk of this storm will be in the form of rain. However, there may be spotty patches of sleet and freezing rain at the onset over the northern and western suburbs.

Farther west, an area of snow and wintry mix is forecast to develop over parts of the Ozark Mountains and the lower Mississippi Valley on Thursday. Road conditions may become slippery from northern Arkansas and southern Missouri to portions of Illinois, Indiana, Ohio, western Tennessee and northern and western Kentucky. This is especially true where sleet occurs or snow falls at a heavy rate.

Cold press on tail end of storm may push snow eastward

During Thursday night, a wintry mix is forecast to spread into part of southern Michigan and southwestern Ontario.

"On Friday, colder air will invade the storm and cause rain or a wintry mix to change to snow over parts of the Ohio Valley and central Appalachians," Dombek said.

This swath of snow is likely to become heavier and more widespread from part of northern and western Pennsylvania to northern and western New York state and New England during the day Friday to Friday night. There is the potential for several inches of snow in some locations, especially over the higher elevations.

There is also the potential for snow or a wintry mix to reach toward the Interstate 95 corridor from northern Virginia to southeastern New England on Friday.

"Typically, storms of this nature just end as rain in the I-95 mid-Atlantic and southern New England," Dombek said.

This is due to a relatively warm ocean this time of the year and a common sweep of dry air at the end of storms.

"However, this could be one of those less common instances where it tries to change to snow at the tail end," Dombek said.

The area from Washington, D.C. to Philadelphia, New York City, Hartford, Connecticut, and Boston have not yet had any snow so far this autumn. There is a chance of the first snowflakes of the season with this late-week storm.

In the wake of the storm, some lake-effect snow will follow over parts of the Upper Midwest to the central and northern Appalachians on Saturday.

A weak storm may also swing across the same region with spotty light snow and flurries during Saturday night and Sunday as waves of chilly air continue to flow in from central Canada.

However, on a positive note for the storm-weary and the upcoming holiday travel surge, the overall pattern from this weekend to next Wednesday is forecast to bring a lack of large-scale and widespread travel disruptions.
