..no severe thunderstorm areas forecast... 


... 
showers and thunderstorms will affect The Four Corners states during 
the day on Sunday...and may spread as far east as the Central Plains 
Sunday night and into Monday morning. 


... 
As the eastern U.S. Upper trough shifts off the middle/southern Atlantic 
coast and across New England...the more slowly advancing western trough 
will remain over the western half of the country. In between...a 
slow-moving ridge will remain aligned roughly along the MS valley. 


With a cool/Continental surface airmass in place over the eastern half 
of the country and high pressure spreading across the northwestern states in 
the wake of an advancing cold front...deep/moist convection should 
be largely confined to The Four Corners states during the day in 
advance of the approaching upper trough. Later...as a nocturnal 
low-level jet increases across the plains...some potential for 
elevated convection may spread as far east as the Kansas/Nebraska vicinity 
through the end of the period.
