  1. Concerning...Tornado Watch 142...
    
       Valid 270027Z - 270200Z
    
       The severe weather threat for Tornado Watch 142 continues.
    
       SUMMARY...Supercells will propagate into central/south-central IA
       this evening. Tornado risk continues for the next few hours. A watch
       extension may be warranted.
    
       DISCUSSION...Multiple long-lived supercells, some producing
       tornadoes, have spread into the northeastern part of ww142.
       Immediately downstream of this activity, boundary layer has
       recovered a bit into central IA, per 58F Td now observed at KDSM.
       Given the progressive short-wave trough aiding this convection,
       there will be a propensity for organized updrafts continuing further
       downstream. While buoyancy is considerably weaker into central IA,
       there is some concern that supercells over southwest IA will spread
       east of the current watch before appreciably weakening. Tornado
       watch may need to be extended east for a few counties to account for
       this risk extending beyond watch expiration.
