Snow to Transition to Wintry Mix, Ice, and Rain Tuesday

The National Weather Service has issued Winter Storm Warnings and Winter Weather Advisories throughout the New York City Tri-State Area. Updated ice accumulation forecasts have indicated a much more significant level of ice accretion for locations to the north and west of the city, making for potentially dangerous roadway conditions Tuesday afternoon as well as setting up the possibility for isolated to potentially widespread power outages going into Tuesday night.

The National Weather Service’s ice accumulation forecast as of 8:41 pm EST on February 11, 2019.

Plan on steady snow developing by mid-morning Tuesday, with the potential for snowfall rates exceeding 1 to 2 inches per hour in the first couple hours of the storm. While the exact timing of the transition from snow to wintry mix (sleet, freezing rain, and snow) depends heavily on specific location, most areas – excluding Long Island, where the transition could occur more rapidly and sooner than elsewhere – will see this changeover around the early to mid-afternoon.

The Weather 360 roadway forecast for Tuesday, February 11, 2019. Please exercise extreme caution during the duration of this storm, with extra attention directed to built up ice and snow on certain roads.

Roadways will become dangerous by early afternoon due to periods of heavy precipitation and ice accretion. Please avoid unnecessary travel during the worst of the storm, with extreme caution on both treated and untreated roadways due to ice, snow, and reduced visibility. Most locations should see conditions rapidly improve Wednesday as temperatures are expected to go above freezing.

Far-Reaching Winter Storm Expected to Bring Heavy Snow, Sleet, Ice, and Rain

2019’s first major winter weather event has now triggered Winter Storm Warnings throughout the NYC Metropolitan Area. Recent runs of short range computer models have indicated larger-than-expected snow accumulations north and west of the city, with some places potentially receiving upwards of 12 inches of snow along with up to a quarter of an inch of ice.

The official Weather 360 Tri-State-wide snow total forecast as of 6:00 pm ET January 18, 2019. As per usual in storms involving ice and wintry mix, the greatest snow totals are most likely to occur in interior locations of New York, New Jersey, and Connecticut to the north and west of the city.

While more areas may see more snow than ice or rain, the potential still exists for upwards of a quarter of an inch of ice to accumulate by early Sunday morning. The threat of ice, along with heavy snow and wind gusts potentially exceeding 50 mph, may lead to downed trees and tree limbs as well as power outages come Sunday afternoon. Coupled with sub-zero temperatures Sunday night, the storm has become potentially serious, especially for those who do experience lapses in electricity.

The official Weather 360 roadway forecast, valid from sundown Saturday afternoon until Monday morning. Exact roadway conditions will be heavily dependent on location, but expect conditions to be especially hazardous during the time frame indicated above. Exercise extreme caution on roadways during and after the storm.

Along with the threat for downed trees and power lines also comes the threat for dangerous road conditions. Roadways will begin deteriorating late Saturday afternoon and, due to the rapid refreezing of any liquid on the ground going into Sunday night, will remain potentially hazardous at least through Monday morning.

More updates will be posted as needed both here and on our Facebook page. Stay safe!

Winter Storm May Bring Snow to The Northeast

The National Weather Service has issued Winter Storm Watches for portions of Eastern New England.  A potentially significant winter weather event is expected to impact the I-95 corridor from New Jersey to Maine starting at the end of the week.   As this is a late-season (or early depending on how you look at it, early-season) snow event, it will likely bring a heavier, wetter snow along with some mixed precipitation.

Starting Sunday afternoon, snow will start accumulating mostly on uncovered dirt surfaces, before quickly moving onto grassy and paved surfaces as the ground cools overtime.   Total accumulations will range from an inch or two, to nearly 10 inches in some spots, with more snow further to the east.

Wintry Mess to Impact the Area Overnight

Locations across the NYC Metro Area are now under Winter Weather Advisories as snow and other wintry precipitation continues to envelop the area.  Tonight, temperatures will continue to rise, and the wintry precipitation now will slowly transition to sleet and freezing rain, before tapering off as some rain showers across the area very early tomorrow morning.  Currently, areas still receiving snow will likely have accumulated 1-3 inches of snow by now, making it somewhat difficult to get around.  Ground temperatures are still below that of the air, meaning that areas receiving snow or other wintry precipitation will likely continue to see more accumulation.  Tomorrow’s commute will be messy in the early morning  until more rain moves in around 9 AM to wash some of the slush and snow on the roads away.

A Winter Weather Advisory is issued when the National Weather Service decides there will be hazardous weather in a certain area that will include some sort of wintry precipitation.

Most Winter Weather Advisories across the area are set to expire tomorrow around 7 AM.
