MD 1153 CONCERNING SEVERE THUNDERSTORM WATCH 385… FOR SOUTHWESTERN THROUGH CENTRAL ARKANSAS
Mesoscale Discussion 1153
NWS Storm Prediction Center Norman OK
0343 PM CDT Mon Jun 03 2024
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.
