Areas affected…portions of central and eastern Louisiana
Concerning…Tornado Watch 711…
Valid 202323Z – 210100Z
The severe weather threat for Tornado Watch 711 continues.
SUMMARY…Ongoing severe storms will continue to pose a risk for a
few tornadoes across WW711 this evening.
DISCUSSION…Across parts of central LA, a band of convection has
shown slow maturation with a couple of supercells becoming
established from the broader convection over the last couple of
hour. Ongoing within a moist, and unstable environment, conditions
look favorable for these storms to maintain intensity this evening.
Strong mid and upper-level shear will continue to favor organized
storms including supercells and short line segments. While surface
winds have veered slightly this afternoon, low-level hodographs
remain long and supportive of strong low-level mesocyclones.
Low-level shear should increase to the east beneath a southwesterly
low-level jet. As storms mature they should remain capable of a few
tornadoes and damaging gusts across central and eastern LA this
evening.
