On a day like today, where we are seeing an elevated potential of severe weather, and considering the fact that most of the state is seeing a slight possibility of tornadic activity, I wanted to examine the helicity values for the state. This model run (12Z) we're looking at in this post is showing helicity values between 250 and 300 m^2/s^2. We have to consider, speed and directional sheering, as wind speeds continue to increase throughout the atmosphere. As you can see these high values are really encompassing the entire state, with slightly lower values for the northern most portion of Litchfield county and southern most region of New London county, otherwise everyone is included.
I would like to stress that we have not been issued any watches or warnings, yet. However, I do expect them soon. The bulk of the sever weather is expected later this afternoon, through the late night hours. If all the ingredients blend perfectly, and we do happen to be hit by a tornado, take shelter in an area of lowest elevation possible.
