Middle Tennessee is getting a break in the rain today and even
some peaks of sun are being noted on visible satellite. Upper
ridging is moving in from the west with the axis over us early
this afternoon. This morning`s upper air run shows ample low level
moisture lingering and models are holding onto this for today.
Scattered to broken low level clouds can be expected today along
with a couple peaks on sun. A light sprinkle can`t be completely
ruled out under the low clouds but those would not be anything
measurable. Overall forecast is on track. Pops were adjusted for
the morning hours to take out the slight chance everywhere except
the plateau where a few light showers have been picked up on
radar. Highs in the low to mid 60s still look reasonable.



Models hanging onto below VFR ceiling thresholds thru 21/12Z BNA
but punching thru the VFR ceiling threshold at least for a portion
of the forecast period CKV/CSV. However, believe the VFR
thresholds will punched thru at BNA also as drier works in from
the south, with sustained sfc winds 5 to 10 kts expected thru
21/12Z, before yet another slug of low level moisture works into
the mid state region 21/06Z-21/12Z. Some VFR fog with some passing
light shwrs in vcnty of terminals thru 20/15Z expected also.
Predominate MVFR ceilings should become VFR around 5 kft
20/18Z-20/20Z. As above mentioned slug of low level moisture
from the south works into region after 21/06Z, ceilings should
return to MVFR thresholds with MVFR/IFR vsbys possible CSV
approaching 21/12Z.
