..no severe thunderstorm areas forecast... 


... 
severe thunderstorms are not expected on Monday. 


..synopsis and discussion... 
Upper pattern, characterized by western Continental U.S. Ridging and eastern 
Continental U.S. Troughing at the beginning of the period, is expected to 
gradually shift eastward and undergo modest deamplification. Several 
shortwave troughs will traverse the southern periphery of the 
eastern Continental U.S. Troughing, helping to send a reinforcing push of cold 
air into the central and eastern Continental U.S.. 


Consequently, cool and stable conditions will prevail across the 
majority of the lower 48 states. The only exception is along the Texas 
and la coasts where a stalled cold front may interact with modest 
low-level moisture to support showers and thunderstorms. Meager 
instability will preclude any severe threat. 


..maximum risk by hazard... 
Tornado: <2% - none 
wind: <5% - none 
hail: <5% - none
