Polar Vortex to Bring Frigid Cold to New England
New England is bracing for a significant drop in temperatures as a weakening polar vortex sends frigid Arctic air southward. A rare Sudden Stratospheric Warming (SSW) event, combined with La Niña, is expected to disrupt the polar vortex, le...
Key Insights
- **Sudden Stratospheric Warming (SSW):** A rare event is disrupting the polar vortex, an event that usually happens later in the winter.
- **Frigid Temperatures:** New England is expected to experience temperatures 10-15 degrees below normal, arriving after Thanksgiving and lasting until mid-December.
- **Unstable Vortex:** The polar vortex is weakening much earlier than usual, making it the most unstable it has been in November since the 1960s.
- **Cold Air Outbreaks:** Regions from the Northern Rockies through the Midwest and into New England will be hit by intense cold snaps.
- **Volatility in Weather:** The unstable polar vortex, combined with La Niña and the Madden-Julian Oscillation (MJO), increases the chances for cold spells and early-season winter snow and ice storms.
In-Depth Analysis
The disruption of the polar vortex is triggered by a Sudden Stratospheric Warming (SSW) event, which involves a warming of the upper atmosphere (stratosphere). This warming weakens the polar vortex, a band of wind that typically keeps frigid air contained at the Earth’s poles.
When the stratosphere warms, it sends waves of warmer air against the polar vortex winds, causing them to slow or reverse. This results in the wobbling, stretching, or splitting of the vortex, releasing exceptionally cold air southward.
According to Judah Cohen, a research scientist at MIT and climatologist, this particular event is expected to deliver cold rather than blockbuster snowstorms, though the latter can't be ruled out. The European model forecasts wind speeds of the polar vortex to slow dramatically by the end of November, potentially leading to a prolonged period of colder-than-normal air in New England.
**How to Prepare:**
- **Stay Informed:** Monitor weather forecasts and alerts from local news sources.
- **Prepare Your Home:** Insulate pipes, ensure heating systems are functioning efficiently, and stock up on emergency supplies.
- **Dress Warmly:** Wear layers of clothing to protect against the cold.
- **Limit Outdoor Exposure:** Reduce time spent outdoors during extreme cold.
**Who This Affects Most:**
- **Elderly:** Older adults are more susceptible to hypothermia and other cold-related illnesses.
- **Low-Income Households:** Those with limited access to heating or adequate shelter are at greater risk.
- **Outdoor Workers:** Construction workers, delivery drivers, and others who work outdoors face increased exposure to the elements.
FAQ
How cold is it expected to get in New England?
Temperatures could drop 10 to 15 degrees below normal for this time of year.
When will the cold snap arrive?
The bulk of the cold is expected to arrive in the first week of December.
Takeaways
- The polar vortex is expected to bring a long cold stretch to New England, starting after Thanksgiving and lasting until mid-December. This event could lead to extreme cold, increased chances of snow and ice storms, and potential disruptions to daily life. Take proactive steps to prepare your home and protect yourself and your family from the cold.
