Areas affected...Southeast KS...North-Central/Northeast OK
Concerning...Severe potential...Watch likely=20
Valid 231933Z - 232200Z
Probability of Watch Issuance...80 percent
SUMMARY...Thunderstorms development is likely across southeast KS
and north-central/northeast OK over the next few hours. Supercells
capable of very large hail and strong gusts are expected, with a
watch likely needed within the next hour or two.
DISCUSSION...Recent surface analysis places a low about 30 miles north-northeast of CNK along the KS/NE border. A cold front extends southwestward from this low across central KS and back into western
OK. A pre-frontal trough also extends southward from this low
through central KS and north-central OK back in southwest OK. The
airmass downstream from these features continues to warm and
destabilize, with temperatures now in the upper 80s/lows 90s,
dewpoints in the low 70s, and MLCAPE around 2500 J/kg.=20
This region is south of the primary forcing, but broad convergence
across the warm sector, along and ahead of the pre-frontal trough,
is contributing to building cumulus. Some more substantial
development is underway southwest of TUL, which may be indicative of
the mode of future pre-frontal development. General expectation is
still for the most of the thunderstorm development to occur later
this afternoon/evening along front. However, given the recent
trends, earlier initiation, possibly along the pre-frontal trough,
is possible.=20
Overall environment supports robust storm development, including
supercells capable of very large hail and strong gusts. A watch will
eventually be needed once signs that more than isolated storm
development is underway.
