1102 AM CST Sun Jan 22 2017
Areas affected...portions of the FL panhandle into far southeast AL
and southwest GA
Concerning...Tornado Watch 20...
Valid 221702Z - 221800Z
The severe weather threat for Tornado Watch 20 continues.
SUMMARY...The near-term tornado and damaging wind threat is
increasing across the MCD area.
DISCUSSION...Conditions are rapidly evolving across parts of the FL
panhandle into far southeast AL/southwest GA. As rapid
intensification of the surface low over Escambia County FL/Baldwin
County AL continues, the warm front is quickly lifting northward
from near the FL/AL/GA border into southern AL/GA. To the south of
the boundary, surface observations over the last hour indicate quick
airmass recovery is occurring with temperatures warming from the mid
60s into the low 70s and dewpoints slowly rebounding. As a line of
strong to severe storms currently extending from near Covington
County AL south/southwest into the Gulf tracks east into the
recovering boundary layer, increasingly favorable deep layer shear
will be encountered. 1636Z VWP data from TLH indicates 0-1km SRH
values great than 350 m2/s2 and the tornado and damaging wind threat
will increase quickly in the short-term across the MCD area.
