Winter storm: Which all places witness record-breaking cold?

A forecast by the National Weather Service updated about the approaching winter storm on Sunday. The weather service has warned that a "multi-day atmospheric river event will continue to impact the Northwest and the Rockies with heavy rain and significant mountain snowfall" on Sunday and into Monday. Atmospheric rivers are narrow channels in the atmosphere that can carry a large amount of moisture with them.

Winter storm warnings are in effect for 11 states, with heavy rain and snow forecast for areas in the Northwest, the Rocky Mountains and eastern United States. The warnings are currently in effect for parts of Colorado, Idaho, Maine, Nevada, New Hampshire, New York, Oregon, Utah, Vermont, Washington and Wyoming. Apart from that, New England and the Northeast also witnessed the record-breaking temperature.

Which areas are witnessing snow and rain?

Parts of the Northeast are currently being swept by a batch of rain showers from southwest to northeast, with the possibility of an isolated severe thunderstorm over parts of Pennsylvania and southwestern New York. At halftime of the Sunday afternoon NFL game between the Arizona Cardinals and Pittsburgh Steelers at Acrisure Stadium in Pittsburgh, a weather delay was initiated due to reports of thunder and lightning in the area. Further north, snow is falling in northern New England, with heavy, wet snow expected to continue overspreading the region through Monday morning.

Where are winter weather alerts in effect?

Winter Storm Warnings and Winter Weather Advisories are posted for most of Maine and New Hampshire, the Green Mountains of Vermont and portions of the Adirondacks and St. Lawrence Valley of northern New York. The National Weather Service said the winter weather alerts are in effect through Monday morning in many areas, except in Maine, where they'll remain in effect until Monday evening.

A rough Monday morning commute expected

The heaviest snow is expected to fall from Sunday night into Monday morning for much of the region, potentially causing travel disruptions for the Monday morning commute in cities such as Augusta and Bangor in Maine, Berlin and Conway in New Hampshire, and Montpelier and St. Johnsbury in Vermont.

How much snow will fall?

Anywhere from 2 to 6 inches of heavy, wet snow is expected to be picked up through Monday morning in most areas under Winter Weather Advisories in coastal Maine, New Hampshire, Vermont, and northern New York. For the areas under Winter Storm Warnings in Maine and northern portions of New Hampshire, Vermont, and New York, a prediction of between 5 and 10 inches of heavy, wet snow has been made. The highest snowfall totals from this winter storm will be seen in the higher elevations.

Scattered power outages are possible

The snow will be heavy and wet, making shovelling more difficult and adding increased stress to trees and power lines, thereby creating a threat of scattered power outages.
