Areas affected...Southwest KS to northwest OK
Concerning...Severe Thunderstorm Watch 383...
Valid 030800Z - 030930Z
The severe weather threat for Severe Thunderstorm Watch 383
continues.
SUMMARY...Increasing potential for strong to severe wind gusts is
expected through dawn as a developing QLCS intensifies across
southwest Kansas. It appears this should eventually track towards
northwest Oklahoma and an additional severe thunderstorm watch will
be considered as it approaches.
DISCUSSION...A 150-km long developing QLCS is ongoing across
southwest KS. While it is initially rooted from elevated parcels and
MRMS MESH cores have flirted around 1 inch, strong surface wind
gusts have been observed (up to 55 mph at the Ulysses AWOS). This
QLCS should intensify as it impinges on increasing buoyancy
advecting across the Panhandles amid a 45-50 kt south-southwesterly
low-level jet per Amarillo VWP data. Surface wind gusts of 55-70 mph
should become more numerous into daybreak.
While the bulk of 00Z CAM guidance indicated MCS development
spreading more easterly across southern KS, the 06Z HRRR along with
00Z NSSL-MPAS suggest a more southeasterly track into northwest OK.
Given the placement of both the MLCAPE/MUCAPE gradient and residual
outflows from prior MCSs, this scenario appears more likely.
