Via the WAVE-3 Weather Team and the Storm Prediction Center:
The Storm Prediction Center has issued a HIGH RISK for severe storms today. I can't stress enough how extremely rare this is...it rarely happens in the Spring let alone in "Winter."[...]
At this point, I would include *ALL* of the WAVE 3 viewing area in the high risk. Below is the statement from the Storm Prediction Center. It's important to note they've included large long tracked tornadoes...this is why the HIGH RISK was issued. It's a lot of "weather talk" but gets to the point.
SPC: THE VERY STRONG VERTICAL SHEAR...MODERATE INSTABILITY...A MOIST LOW-LEVEL ENVIRONMENT...AND THE LIKELIHOOD OF A FEW DISCRETE WARM SECTOR SUPERCELLS / AND SUPERCELLS WITHIN THE LINE ALONG THE FRONT/...ALL APPEAR SUPPORTIVE OF A POTENTIALLY SIGNIFICANT TORNADO EPISODE WITH A FEW LONG-TRACK/STRONG TORNADOES. THE MOST PROBABLE AREA FOR DAMAGING TORNADOES WILL BE SE OF THE SURFACE LOW TRACK IN THE MORE ESTABLISHED WARM SECTOR...OR NEAR AND S OF THE OH RIVER FROM EXTREME SRN INDIANA INTO CENTRAL KY/NRN MIDDLE TN. BOTH PRE-FRONTAL AND FRONTAL SUPERCELLS ARE MOST PROBABLE IN THE HIGH RISK AREA...AND SOME OF THESE STORMS COULD SPREAD AS FAR NE AS SW OH AND WRN WV BEFORE EXITING THE WARM SECTOR THIS EVENING. OTHERWISE...DAMAGING WINDS AND LARGE HAIL CAN ALSO BE EXPECTED WITH THE PRE-FRONTAL AND FRONTAL STORMS THROUGH THIS EVENING.
