The severe weather threat for Severe Thunderstorm Watch 64
SUMMARY...Isolated strong to severe storms will continue across
portions of western north Texas into the Rio Grande region this
evening. Uncertainty exists with regards to additional storm
development and Severe Thunderstorm Watch 64 continues across the
DISCUSSION...Some uncertainty continues with regards to additional
convective development into the nighttime hours across parts of
western TX. A line of storms that developed early ahead of the
dryline will continue to lift east/northeast across north TX while
isolated cells persist further south toward the Big Bend vicinity.
Hi-res HRRR guidance continues to insist additional development will
occur along the retreating dryline. Additionally, guidance continues
to indicate that storms developing across the Rio Grande in Mexico
will lift northeast overnight into parts of west TX. A lack of more
robust storm development along the Sierra del Burro and some modest
growth of cumulus along the dryline call this scenario into
question. Given uncertainty, and an environment that will continue
to support severe storms should they develop, Severe Thunderstorm
Watch 64 continues.
