After Brief Warmup, Winter to Tighten Grip With Return of Polar Vortex

View Comments ()



    A brief warmup to the 50s over the next few days will be followed by another return of the polar vortex to the tri-state area and a chance of snow next week.

    Temperatures surged amid gusty thunderstorms on Friday and will be followed by a mild weekend with 51 on Saturday and 45 on Sunday.

    But then, the weather turns frigid again.

    Temperatures drop into the 30s on Monday, Tuesday and Wednesday, and there's a chance of snow Tuesday.

    After that, winter will tighten its grip on the region as a swirl of arctic air pushes south again, sending daytime temperatures into the teens and 20s, with single-digit lows at night.

    Expect that cold to begin next Thursday into Friday.

    The polar vortex is a system that usually stays near the North Pole and Canada, but last month slid south and pushed temperatures to bone-chilling record lows.
