Mesoscale Discussion 2055
NWS Storm Prediction Center Norman OK
0340 PM CDT Wed Sep 11 2024
Areas affected...portions of southern Alabama into the western
Florida Panhandle
Concerning...Severe potential...Tornado Watch likely
Valid 112040Z - 120015Z
Probability of Watch Issuance...80 percent
SUMMARY...The tropical-cyclone tornado threat should gradually
increase through the remainder of the afternoon. A Tornado Watch
will eventually be needed.
DISCUSSION...The center of Hurricane Francine continues to translate
northeast as it approaches the LA coastline. Extending
east-northeast of Francine's center is a zonal rainband, comprised
of relatively discrete cells (some possibly transient
supercellular). At the moment, these storms are percolating in
intensity offshore, where a greater theta-e/buoyant airmass resides.
However, this airmass is expected to gradually advect
northward/inland with the north-northeastward progression of
Francine through the afternoon and evening hours. HDC and MOB VADs
show increasing hodograph sizes/curvature, indicating stronger
low-level shear become established along the Gulf Coast. As such, a
corresponding tornado threat should increase with the more favorable
low-level warm-air/moisture advection. A Tornado Watch will
eventually be needed.
