Valid 291258Z - 291430Z
The severe weather threat for Severe Thunderstorm Watch 413
continues.
SUMMARY...The threat for significant damaging winds up to around 80
mph will likely increase this morning across northern Missouri.
DISCUSSION...A couple of supercells and bowing clusters are ongoing
this morning across far northeastern KS, southwestern IA, and
northern MO. The most intense cluster is across northwestern MO,
where a recent measured wind gust to 68 kt (78 mph) has been
observed. As the boundary layer continues to destabilize with
diurnal heating, the very strong instability (MLCAPE 3000+ J/kg) and
steep low/mid-level lapse rates will support an increasing threat
for significant severe downdraft winds up to around 80 mph. The
greatest threat for these substantial damaging winds will likely
focus across northern MO where the primary bowing cluster should
consolidate. Isolated large hail may also occur with any embedded
supercells.
