Record cold this weekend? Doesn’t happen much any more.

The National Weather Service is pointing out the intense cold snap coming our way this weekend.

Here’s forecast map of temperatures a mile up (850mb pressure height) in the atmosphere for Saturday night.  If we were to bring these temperatures down to the surface, warming as its pressure increases, our surface temperature wouldn’t be above 5 degrees Fahrenheit.

850mb heights and temperatures (degrees C) 10pm Sat Feb 13 (03GMT Sun Feb 14) Notice -30 deg C in the northeast US (1 mile up). Good luck finding a colder place.

But this air won’t be sticking around long enough to give us more than a few days of record-setting cold weather.  Here’s the forecast discussion from the NYC NWS….
