Weather - The Big Chill


The Big Chill

By Gerard Roe
Staff Meteorologist

Numbingly cold weather has extended its grip on the region. Some slight moderation in temperature can be expected mid-week, along with a threat of light snow continuing on to week's end. A substantial chunk of the swirling polar vortex has split off and descended southward, and is now sitting squarely over the western North Atlantic.

In combination with brisk surface winds, the temperature today will feel like a spit-crackling -10F (-23C). The bitter weather will loosen its hold somewhat, with temperatures Wednesday pushing up toward freezing. There are some small cyclonic systems circulating the edge of the larger vortex, and while there is vertical motion associated with them, the polar air remains too cold for much snow. The best chance for anything other than a dusting looks to be Wednesday night/Thursday morning with up to a couple of inches possible.

Today: Bitterly cold. Gusting winds from the west 1520 mph (2432 kph). Mostly clear. High 19F (-7C).

Tonight: Clear and cold. Low 10F (-12C).

Wednesday: Clear in the morning. Becoming cloudier throughout the day. A dusting of 2 inches (5 cm) likely overnight. High 29F (-2C). Low 20F (-7C).

Thursday: Chance of snow. High 28F (-2C). Low 18F (-7C).
