Thundersnow12 Posted August 12, 2011 Share Posted August 12, 2011 pretty awesome occlusion seen on velocity in the lowest level over the last few scans.. low level meso begins to strengthen with around 80kts of shear over close to 3 miles couplet begins to intensify and tighten up RFD pushes out and main meso starts to occlude but really tighened back to the northwest and might of put down a tornado at this time.

Do we have aspecial name for a cell on the back of a line like this one? Also I like the fact that no cells are forming behind that one. Leaves it undisturbed.
