Severe Weather Risk Friday April 4


Surface based CAPE per GFS at noon on Friday 4/4/08


Vorticity values per GFS at noon on Friday 4/4/08


Storm Prediction Center Day 3 Outlook effective Friday 4/4/08

Severe storms seem likely across Alabama Friday afternoon and Friday night. The GFS model indicates that surface based instability values of over 1,000 j/kg show up in West Alabama Friday afternoon. Helicity values also seem pretty high at the same time. Based on this, supercell storms will likely precede a squall line that will move through Friday night.
