1201 AM CDT Sun Jun 18 2023
Areas affected...Northeast Oklahoma
Concerning...Severe Thunderstorm Watch 329...
Valid 180501Z - 180600Z
The severe weather threat for Severe Thunderstorm Watch 329
continues.
SUMMARY...A fast-moving MCS will likely produce significant wind
gusts across the Tulsa area over the next hour. Wind speeds appear
likely to peak at over 80 mph.
DISCUSSION...The latest high-resolution radar imagery from Tulsa
shows a well-organized fast-moving bow echo, which is currently
approaching the city of Tulsa. The bow echo is moving at near 55
knots, according to measurements of the bow's apex. In addition,
base velocity from Tulsa showed estimated winds above 90 knots at
about 3000 feet above the ground. This should translate to
significant wind gusts ahead of the bow at the surface. It appears
that wind speeds of at least 80 mph will accompany the bow echo as
it moves through the Tulsa metro over the next hour.
