Areas affected...southwestern through central Arkansas
Concerning...Severe Thunderstorm Watch 385...
Valid 032043Z - 032245Z
The severe weather threat for Severe Thunderstorm Watch 385
continues.
SUMMARY...A slowly organizing cluster of thunderstorms will
overspread much of central Arkansas, including the Little Rock
vicinity, through 5-7 PM CDT, with a continue risk for strong to
occasionally severe wind gusts. Trends will continue to be
monitored for a possible additional watch downstream, WW 385 could
be locally extended northeastward through central Arkansas.
DISCUSSION...The ongoing cluster of storms has become a bit better
organized, with a developing mesoscale convective vortex now east of
Fort Smith, and 50 kt west-northwesterly rear inflow in the 1-3 km
AGL layer evident on the Fort Smith VWP. The leading edge of the
convective outflow, and stronger convective development, is still
advancing eastward at a relatively modest 30+ kt. However,
boundary-layer destabilization is ongoing immediately ahead of the
outflow into central Arkansas, where 2-hourly surface pressure falls
are maximized (around 3 mb) near Little Rock. This could support at
least some further intensification and acceleration into early
evening.
