645 FXUS64 KOHX 080657 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 157 AM CDT Sat Jun 8 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today through Sunday night) Issued at 126 AM CDT Sat Jun 8 2024 Quite the pleasant night across Middle Tennessee with current temperatures in the mid 50s to mid 60s with comfortable dewpoints in the mid to upper 50s. This pleasantry will gradually come to an end today as clouds and low level moisture begin increasing ahead of an incoming but dying MCS approaching from the northwest. Still appears a few showers will move across at least northern parts of the cwa late this morning into the afternoon with the remnants of the MCS, so will keep a slight chance pop through then but the evening looks dry. Rain chances will increase significantly after midnight tonight into Sunday morning as widespread showers and thunderstorms arrive from the northwest thanks to a passing shortwave trough. Highest pops will be across the northern two-thirds of the forecast area, which is in line with the latest HRRR model runs. Could see a couple strong storms as well with gusty winds as forecast soundings show fairly strong deep layer shear for early June up to 50 knots, but instability appears weak which will keep any threat low. Bulk of showers and storms will move out of the area by midday Sunday, but some scattered activity is still likely through the afternoon - and again can`t rule out a strong storm or two. Cold front will sink southward through the midstate Sunday night and end precip chances from north to south. && .LONG TERM... (Monday through next Saturday) Issued at 126 AM CDT Sat Jun 8 2024 Forecast for next week looks unusually quiet for mid-June due to a building upper level ridge along the Gulf Coast and weak northwest flow aloft, both of which will keep us high and dry. Post-cold front airmass for early next week will make it feel quite nice for this time of the year, with highs only in the mid 70s to low 80s and comfortable dewpoints down into the 50s. Unfortunately, low level moisture and temperatures will begin rising by midweek as low level flow becomes more southerly and upper ridging strengthens, so we will enter our more typical hot and humid summertime weather regime as we reach mid June. Highs look to heat up back into mid 80s to low 90s from Thursday onward as dewpoints increase into the 60s and low 70s, which will create uncomfortable heat indicies in the mid to upper 90s. && .AVIATION... (06Z TAFS) Issued at 1223 AM CDT Sat Jun 8 2024 Expecting mainly VFR conditions for all terminals through the TAF period. Some MVFR fog will be possible at KSRB overnight, and could also occur at KCSV. Short term models do develop some showers moving in from the northwest after 12Z, and could impact KCKV/KBNA/KMQY, but model confidence is low on coverage, so kept VFR conditions at those terminals for now. Southerly winds around 5 to 10 knots will return by 15Z at all terminals and continue through the early evening. && .PRELIMINARY POINT TEMPS/POPS...
