Snow-Eating Windy Warmth

This evening’s sounding from KOKX really tells the story.

We’re loaded with moisture (PWAT an impressive 1.46″!) and we also have quite a low level jet off the deck! In fact just about 2000 feet off the ground winds are over hurricane force. 69 knots, in fact!

What the sounding shows us is, as usual, the southerly LLJ is being held at bay by a fairly strong inversion. It’s possible convection or inertial gravity waves later this evening may promote enough mixing to bring down 50 knot gusts. With leaves off the trees and frozen ground the amount of tree damage should be isolated or scattered. Sporadic downed limbs and power outages are possible.

The LLJ is going to strengthen overnight. Take a look at the NAM 850mb wind speeds for 9z Thursday morning. 106 knots over central Connecticut is nothing to sneeze at.

Most of the rain will be gone by 8 a.m. tomorrow and then temperatures will fall through the day Thursday. Enjoy the warmth and wind while it lasts!

  1. Am I correctly reading the sounding to say that if the air at the 500 mb level were mixed down to the surface its temperature would be over 100 degrees F. What would its dewpoint be. That would be a chinook and a half! N
