..no severe thunderstorm areas forecast... 

thunderstorms will be possible across the Southern Plains and 
southern New Mexico Friday...however severe storms are not expected. 

A blocking pattern will result in little change to the large-scale 
flow aloft on Friday with an upper-level low remaining over the 
Great Basin and ridging aloft over the Gulf of Mexico/southeast U.S. 
Stronger flow aloft will remain from the southern rockies east to 
the southern/Central Plains. A strong cold front will continue 
moving south and extend from the southern Great Lakes southwest into 
central/southwest Texas by Friday evening. 

Latest guidance remains in agreement in developing generally weak 
instability in the vicinity of the cold front over central Texas 
Friday afternoon...where widespread cloudiness should limit diurnal 
heating despite middle-upper 60s surface dew points. In addition...this 
area will be generally south of the more favorable deep-layer shear. 
A few thunderstorms are expected near the front...however the severe 
threat appears low. 

Behind the front...precipitation will be widespread from the 
southern rockies east across the Southern Plains and middle-Mississippi 
Valley...and an isolated lightning strike is possible across 
Texas/southern Oklahoma in the presence of weak elevated
