Area forecast discussion, Dec 23, 1:33 PM CST, 7 hours 28 minutes before
Area Forecast Discussion National Weather Service Nashville TN 133 PM CST Sat Dec 23 2017 .DISCUSSION... Cold front has finally cleared the mid state with high pressure now building in from the northwest. Still, considerable low clouds remain, and Middle Tennessee won't actually scatter out until after the next shortwave passage tomorrow evening. The deepest moisture will stay to our north with this next system, although the mid state will get a glancing blow, mainly across our north, with a chance of light rain tomorrow afternoon and possibly some light snow across the Cumberland Plateau on Sunday evening. High pressure will remain situated to our west for the foreseeable future so that the cold air will be reinforced beginning tomorrow night as lows drop well into the 20's. In fact, we won't see any appreciable return flow until sometime after the 7-day forecast period. That means temperatures from tomorrow through at least next Saturday will remain entirely below normal by several degrees. The GFS & ECMWF start to diverge toward the end of next week, but both suggest some sort of active system by Thursday or Friday that would include wintry precipitation, although confidence in timing and impact is quite low at this time. && .AVIATION... 18Z TAF DISCUSSION. Passing frontal boundary now near CSV...with associated heavy precip well east. In its wake however...Deck of low CIGs extents well up stream...as well as light showers/patchy drizzle. lingering deep low-level moisture expected to keep conditions MVFR/IFR mainly with CIGs today...and both CIGs/VSBYs tonight as fog/drizzle development again probable. VSBY may improve after 14z/SUN but CIGs likely to remain low. && .PRELIMINARY POINT TEMPS/POPS...
