Areas affected...portions of east-central and northern MO

Concerning...Severe Thunderstorm Watch 287...

Valid 200249Z - 200345Z

The severe weather threat for Severe Thunderstorm Watch 287
continues.

SUMMARY...An isolated severe threat may continue in and west of
Severe Thunderstorm Watch 287, however a new watch is not
anticipated.

DISCUSSION...Strong/occasionally severe storms were occurring across
east-central/northeast MO as of 0225z.  Trends in radar/reports
continue to show a general decrease in intensity over the watch area
during the past hour as MLCIN gradually increases due to nocturnal
cooling.  The more likely area for additional thunderstorm
development over the next few hours is west of the current watch
over north-central MO, where modest convergence and lower MLCIN is
present.  With strong instability and 25-30 kts of effective shear,
the potential for an isolated severe storm will exist for the next
few hours.

Given the expected isolated nature of the remaining severe risk, an
additional watch is not anticipated however convective trends will
be monitored.
