Valid 220214Z - 220315Z
The severe weather threat for Tornado Watch 15 continues.
SUMMARY...Severe/tornado risk continues to gradually shift northeast
out of Tornado Watch 15 into adjacent watches.
DISCUSSION...Latest radar loop shows isolated strong/locally severe
storms moving east-northeast across parts of southeast Louisiana
mainly north of I-10/I-12, near and north of the slowly
northward-advancing warm front. The evening LIX RAOB revealed a
very potent severe-storm environment -- both kinematically and
thermodynamically -- in the vicinity of the front, which continues
to spread northeast into parts of Mississippi and Alabama. Though
local risk may linger across WW 15 beyond the scheduled 22/03Z
expiration, expect the main severe/tornado potential to shift north
of the watch over the next couple of hours.
