Concerning...Tornado Watch 249...
Valid 192356Z - 200200Z
The severe weather threat for Tornado Watch 249 continues.
SUMMARY...Severe/isolated tornado threat continues across mainly
northern/western parts of the watch area.
DISCUSSION...Storms have been slow to develop across the bulk of
watch 249 this afternoon and evening, with most storms remaining on
the northwestern periphery of the watch. Here, bands of
thunderstorms -- including several bowing structures -- are ongoing.
Hail and locally damaging winds remain the primary concern with
these storms, though a brief tornado or two will remain possible
within rotating portions of the convective bands. With time, while
individual convective clusters moving quickly northeastward, the
overall band of convection will spread slowly east across the watch
area as the surface cold front advances.
Farther south into Texas, a few small isolated/rotating cells have
evolved south of Stephenville (the Hamilton/Coryell County
vicinity). With storms ongoing just west of this convection across
parts of Tornado Watch 246, severe risk will likely remain greater
-- in a relative sense -- across the far southern portions of the
watch as opposed to areas farther north into the DFW metroplex over
the next 1-2 hours.
