Went with a compromise latest model GFS/ECMWF solution. Will 
continue to keep the mid state dry thru Fri morning per ridging
influences. Best chance of rainfall continues to look like it
will be during the Fri night time frame with some mdt rainfall 
possible. Increasing chances of light shwrs from the west as Fri 
afternoon progress. Decreasing chances of light shwrs from the 
east to west as Sat progresses. Sfc frontal passage expected 
during the day on Sat and again during the day on Tue providing
reinforcing cold air advection shots to the mid state region. 
Mentioned patchy frost Sat night across the Cumberland Plateau 
Region and much of the mid state on Sun night with overnight low 
temps expected in the mid 30s across these locations. Some 
differences noted in the depicted model solutions late week when 
it comes to the expected evolution of the wx pattern between the 
latest GFS/ECMWF solutions. Leaned toward the drier ECMWF solution
at this point for forecast consistency. Leaning toward this 
solution will keep the mid state dry thru at least the first half 
of next work week. Only mentioned a slight chance of light shwrs 
Wed night into Thu night. Afternoon high temps and overnight lows 
will continue to remain below seasonal normal values thru the 
second half of next week. Exception to this will be n Fri night 
with lows in the upper 40s to lower 50s.
