Late-March Polar Vortex Split Could Send a Chill Into the Northeast
Forecasters expect a brief warmup first, with upcoming model runs clarifying how far south the cold air reaches.
Overview
- Long-range guidance points to a possible split in the polar vortex by late March, according to FOX Weather.
- A split could displace Arctic air into parts of the Northeast and Mid-Atlantic, bringing below-average temperatures to areas including Philadelphia, Washington, D.C., and New York City.
- Exact placement of the coldest air remains uncertain, leaving open whether local impacts amount to a notable cooldown or only a short dip.
- Widespread snow is not currently anticipated, though a brief return to wintry chill is possible.
- Meteorologists will monitor and update forecasts over the coming days, and many view this as likely the season’s final significant polar-vortex influence.
