The latest from AccuWeather on the snow storm


AccuWeather reports latest storm moving quickly. report after blasting the Midwest and Great Lakes on Monday and Monday night, a complex, fast-moving storm will bring heavy snow to parts of the Northeast on Tuesday.

Delays are likely during the morning commute along the I-95 corridor from Philadelphia to New York City due to the snow that fell earlier. Bursts of heavy snow were pushing across Long Island, New England, western and central Pennsylvania and upstate New York for the morning drive and late morning hours.

Hundreds of flights have already been canceled or delayed across the Northeast. Many schools have been delayed or canceled Tuesday.

According to AccuWeather Senior Meteorologist Alex Sosnowski, “In most cases, the storm will last six hours or less, but a few locations can receive just as many inches of snow during that time.”

During the afternoon hours on Monday, Chicago, was slammed with blinding snow and snowfall rates of 1 to 3 inches per hour. Chicago received 5 inches of snow from the storm, raising their seasonal total to 67.9 inches. For the city, this season now ranks as the fifth snowiest on record.

An onslaught of winter storms has buried much of the Northeast over the past few weeks. While this upcoming storm is not expected to be an historic event, it can snarl travel, resulting in more flight delays in a winter already full of them.

“The storm has had a history of thunder and lightning with the snow, sleet and freezing rain in Illinois and part of Indiana, which is the sign of a vigorous system and the potential for brief bursts of snow farther to the east into Tuesday,” Sosnowski said, “Some areas in the Northeast may also experience a thunderstorm on Tuesday.”

The Northeast will feel the impacts of the storm on Tuesday as the storm from the Midwest continues to affect part of the central Appalachians and a secondary storm on the coast impacts New England and Long Island.

Shovels and plows will be needed again in many areas. Some locations from Pennsylvania to New England could experience snowfall rates of 1 to 3 inches per hour for a brief time.

Interstates 76, 80, 81, 90, 95 and 99 will be slick for a time on Tuesday.

Flight delays and cancellations are anticipated for many major hubs, including Philadelphia, Boston and the three major airports around New York City.

The snow could once again force administrators to delay or cancel school, adding to the growing list of school cancellations this winter.

The risk of roofs collapsing will increase with each snowfall event, where not enough prior melting has reduced the amount of snow. For example, as of Monday morning, Feb. 17, 2014, much of Pennsylvania has between 1 and 2 feet of snow on the ground and on roofs.

“In some cases, upcoming melting can add to the risk of roof failure in the short term,” Sosnowski said, “Lingering snow can block the drainage system on flat roofs, leading to uneven weight distribution when melting occurs or when rain falls into the snow.”

Most gable roofs can sustain a significant amount of snow and allow the water to settle toward the edges. However, a buildup of ice in the gutters can force water beneath the shingles along the edges.

Slippery sidewalks will remain a concern as the snow falls, and with cold nights and milder days in the wake of the snow, icy patches will develop. The new snow can hide patches of ice beneath.

For those in search of warmth, a brief break from the snow and cold is in store for the middle and end of the week.

A storm developing over the Central states late in the week may bring severe weather and flooding problems to some communities.
