Areas affected...Central/North-central KS
Concerning...Severe potential...Watch possible
Valid 112041Z - 112245Z
Probability of Watch Issuance...40 percent
SUMMARY...Severe thunderstorms may develop across north-central and
central KS this afternoon. Trends are being monitored for possible
watch issuance.
DISCUSSION...Recent visible satellite imagery shows an increasing
agitated cu field along and just ahead of the approaching cold
front. Airmass south of the front is well-mixed with temperatures in
the upper 90s/low 100s and dewpoints in the mid 60s. This mixing has
eroded much the convective inhibition and the expectation is for
continued convergence along the cold front to result in eventual
convective initiation. However, given the amount of dry mid-level
air (sampled well by the 19Z TOP sounding), there is some question
as to how long it will be before this initiation takes place.
Additionally, convergence decreases with southern extent across KS,
casting uncertainty regarding the occurrence of thunderstorms into
central KS in the near-term. As a result, a conditional risk for
severe hail and wind exists across north-central/central KS. Trends
will be monitored for convective development and possible watch
issuance.
