Areas affected...Portions of western Kansas
Concerning...Tornado Watch 200...
Valid 242237Z - 250030Z
The severe weather threat for Tornado Watch 200 continues.
SUMMARY...Brief tornadoes continue to be reported northeast of
Colby, KS. While this storm continues to interact with the outflow
boundary, similar tornadic activity can be expected. Tornado
potential is expected to increase in southwestern Kansas as the
low-level jet increases, so long as storms remain discrete over the
next 1-3 hours.
DISCUSSION...A supercell northeast of Colby, KS has continued to
produce funnels and brief tornadoes over the last 2 hours. This
activity may continue as long as this storm continues to interact
with an outflow boundary. To its east, winds have veered to
southerly. To the south near Garden City, KS, storms have slowly
moved south-southeastward. To this point activity has remained
discrete. Given the position of the surface low and the expected
increase in the low-level winds in southwestern Kansas this evening,
wind profiles are expected to become more favorable for tornadoes
over the next few hours. There appears to at least an hour or two
window where storms will remain discrete before upscale growth and
storm interactions reduce tornado potential later in the evening.
Large hail and damaging wind gusts will also remain a concern.
