Areas affected...extreme southwest Nebraska...much of western
Kansas...and portions of northwest Oklahoma

Concerning...Severe Thunderstorm Watch 265...

Valid 020053Z - 020300Z

The severe weather threat for Severe Thunderstorm Watch 265
continues.

SUMMARY...Severe thunderstorms with a history of strong winds and
large hail continue across western Kansas this evening. The overall
environment ahead of these storms remains very favorable for severe
weather. As such, the severe threat will continue across Severe
Thunderstorm Watch #265 and a new watch may be needed across
portions of northwest Oklahoma and southwest/south-central Kansas
later this evening.

DISCUSSION...Multiple areas of thunderstorms are ongoing across
Severe Thunderstorm Watch #265. The northern most severe storm is an
isolated cell moving east along the Thomas/Logan County line.
Although MRMS depicts maximum hail sizes between 1-1.5", a recent
report from an EM in Logan County reports copious amounts of 0.88"
hail rather than fewer, larger stones.

To the southeast of this cell, an evolving linear cluster has taken
shape from Lane to Gray Counties, with a southeast moving supercell
occurring ahead of this line. A measured 80 MPH wind gust occurred
earlier this evening over Lane County with the leading supercell,
and a more recent report from Ness county indicates 1.75" hail is
now or recently occurred. With the linear segment, a measured 61 MPH
wind gust occurred as the linear moved across Scott County and a 70
MPH wind gust reported by the Garden City ASOS.

Additional severe storms have developed across far southwest Kansas
across Morton and Grant Counties. MESH cores with the Morton cell
continue to increase and wind damage was recorded in Johnson, KS as
the Grant County cell moved through Stanton County.

The overall environment ahead of these clusters remains very
favorable for severe thunderstorms. MUCAPE increases from around
2000 J/kg where the storms are now, to greater than 3500 J/kg across
northwest Oklahoma into central Kansas. Effective-layer shear is
also quite favorable, with widespread 35-40 knots objectively
analyzed across the region. This should sustain ongoing convection
and support severe potential with any new development.

Recent observations and high-resolution guidance suggests that the=20 development linear MCS across Lane-to-Gray Counties will continue to
develop south-southeast this evening. As mentioned, the overall
environment ahead of these storms remains very favorable for large
hail and damaging winds. As such, a new watch may be needed later
this evening across portions of northwest Oklahoma and
southwest/south-central Kansas.
