Severe Thunderstorms Possible Wednesday/Thursday
May 30, 2012 Leave a comment
Severe weather will be possible for parts of the south today as a frontal boundary stalls out over the area. Very steep lapse rates, mid/upper 60s dewpoints, CAPE values of 2,000 to 3,000, and LIs of -9 to -12 will be quite supportive of strong updrafts resulting in damaging winds of 60-70 mph and golfball size hail.
A slight risk for severe weather has been issued for Thursday from east Texas to the Ohio valley. As of now there is a 30% probablistic risk for severe weather for parts of LA, AR, MS, AL, TN, and KY. Sufficient moisture, strong lift, and increasing wind fields coming together ahead of a cold front will result in damaging winds and hail once again being the primary threats on Thursday. Additionally, there could be a period where a tornado or two will be possible Thursday night due to increasing low level shear.
