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.
