Areas affected...portions of central and north-central Texas
Concerning...Tornado Watch 47...
Valid 242310Z - 250015Z
The severe weather threat for Tornado Watch 47 continues.
SUMMARY...The severe threat continues across WW 47.
DISCUSSION...Scattered cellular convection, including a few
supercells, have evolved near/just east of the DFW metro area over
the past hour. Additionally, a longer-lived supercell over San
Saba/Mills/Hamilton counties has recently produced 1.5-1.75 inch
hail. Additional shallow convection has deepened in the past 15
minutes along the I-35 corridor between Waco and Hillsboro. The
storms are in a favorable environment for updraft rotation, with
southeasterly low-level flow veering strongly with height amid weak
to moderate instability. Additionally, the cells just east of DFW
appear to be interacting favorably with a warm front lifting
northward along the I-20 corridor in that area. As gradual
low-level moistening continues, surface-based convection is expected
to continue to pose a risk for tornadoes in addition to hail
(potentially significant near supercells). A greater tornado risk
may evolve after the 00Z time frame pending backing of low-level
wind fields due to cyclogenesis along the Rio Grande/Big Bend area.
