Area Forecast Discussion National Weather Service Nashville TN 1115 PM CST Tue Mar 6 2018 .UPDATE... FOR 06Z AVIATION DISCUSSION. && .DISCUSSION... Cold front stretches from central IL southwest through eastern OK. this feature will move rapidly our way and clear our area by midnight. Meanwhile, a strong upper level trough axis will amplify and push across the mid state after midnight. The airmass is very dry but some light rain/snow could get squeezed out of an increasingly colder overnight. Amounts will be very light and will only include a low chance of measurable precip along the Plateau. Otherwise, flurries and sprinkles appear likely across the north and east. Moving on, a couple more weak impulses may bring additional flurries, to mainly our north and east through Wed nt. Temperature wise, it will be rather cold for early March. The appreciably low 850 mb temps of -6c to -9c...will prevent much of a warmup over the next 2 afternoons. After lows tonight in the lower to mid 30s, the mercury will hold in the 40s for Wed and Thu. Freezing temps are on tap for Wed nt and again on Thu night. This is quite typical for early March. In the extended forecast, The upcoming weekend storm system appears to be taking a more northerly track. Thus, pops are looking higher for that Sat through Sun period. Furthermore, with the more northerly track, instability looks a little better and thus, more in the way of thunder will be included. 1 to 2 inch rainfall amounts are still expected. The upper system is also looking as though it will take a more northerly track. Will therefore steer clear of any frozen precip inclusion. Temps through the extended are looking seasonal. && .AVIATION... 06Z TAF DISCUSSION. VFR conditions are forecast for the first part of the forecast period. However, as an area of stratocumulus ceilings sinks southeastward toward the Mid-State late tonight and early Wednesday, expect conditions at area terminals to become MVFR as we head toward sunrise, eventually recovering back to VFR ceilings after 17z and remain VFR for the rest the forecast period. Gusty west to northwest surface winds will continue through 00Z/THU forecast period, as a tight pressure gradient remains in place across Middle Tennessee. A few light flurries are possible at CSV late tonight, although probabilities remain sufficiently low so as not to require a mention of prevailing light snow in the TAF. A period of VCSH remains in use in the CSV TAF to highlight the timing of the best chance of seeing light flurries. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......13 AVIATION........19
