Areas affected...portions of central Missouri

Concerning...Severe potential...Watch unlikely=20

Valid 190408Z - 190545Z

Probability of Watch Issuance...5 percent

SUMMARY...A couple instances of marginally severe hail may occur
over the next couple of hours. A WW issuance is not expected.

DISCUSSION...An embedded 500 mb impulse is overspreading MO,
contributing to locally higher deep-layer shear (e.g. 40+ kts of
effective bulk shear per 03Z mesoanalysis), as well as deep-layer
ascent. As such, a few transient supercells have developed, with
MRMS mosaic radar data suggesting that some of these storms are
producing hail that is approaching severe limits. Mid-level lapse
rates are not particularly steep, as shown by the 00Z SGF observed
soundings, which depicts near 7 C/km mid-level lapse rates atop a
stabilizing boundary layer. While an instance or two of 1+ inch
diameter hail may be observed, the aforementioned tall/thin CAPE
(with MLCAPE around 1000 J/kg) and modest deep-layer shear suggest
that severe hail should be overall isolated. As such, a WW issuance
is not expected.
