Severe weather parameters are "marginal" today, and the forecast discussions do not exactly provide ringing endorsements for severe weather.

From SPC: "LOW-LEVEL SHEAR WILL BE MORE FAVORABLE FOR TORNADIC SUPERCELLS FROM NE SD INTO ERN ND INVOF THE WARM FRONT...BUT SURFACE-BASED STORM DEVELOPMENT IS QUITE UNCERTAIN THIS AFTERNOON."

From Twin Cities NWS forecast discussion: "KMSP...A FEW LIGHT SHOWERS PASSING THE AIRPORT OUT THE GATE THIS MORNING...BUT NO REAL ORGANIZED ACTIVITY SEEN TODAY/TONIGHT."

Springfield, Mass: Latest "Urban Tornado" casualty

This is getting crazy.

Tuscaloosa, Joplin, Minneapolis and now Springfield, Massachusetts. The list of "tornado towns" in 2011 continues to grow. So much for the myth that tornadoes do not strike urban areas.

When the tornado struck the 3rd largest city in Massachusetts Wednesday at rush hour, amazing video shows the debris cloud and something we rarely see on video. The tornado literally sweeps across the Connecticut River, shattering another myth that bodies of water can stop tornadoes.

Look closely at the amazing video below and you can see cars stranded on a bridge that take a direct hit from the tornado. Imagine the feeling of sheer panic as the cars are trapped on a bridge, over water and inside the swirling tornado vortex.

Damage reports form the Springfield NWS office here.
