Areas affected...Far North-Central TX

Concerning...Tornado Watch 308...

Valid 260316Z - 260415Z

The severe weather threat for Tornado Watch 308 continues.

SUMMARY...An intense supercell capable of producing a strong tornado
is expected to continue for at least the next hour over far
north-central Texas.

DISCUSSION...Recent radar imagery has shown an notable increase in
intensity of the supercell over Montague and Cooke County in far
north-central Texas. Echo tops now over 60 kft, with a very strong
low-level circulation observed as well. Recent mesoanalysis
estimates that effective helicity is over 800 m2/s2 and effective
shear is over 70 kt near this supercell. This intense shear coupled
with very strong buoyancy (i.e. 4500 J/kg) is resulting in STP
values from 16 to 18. Given the supercellular mode, a strong tornado
is possible within this environment. An extension in time for
Tornado Watch 308 may be needed.
