Area Forecast Discussion National Weather Service Morristown TN 231 PM EDT Sat Jun 7 2025 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This evening through Sunday night) Issued at 230 PM EDT Sat Jun 7 2025 Key Messages: 1. An approahcing MCS will track across the area this evening, with damaging winds and flooding being the primary hazards, mainly south of I-40. 2. Scattered showers/storms continue into Sunday morning, exiting to the east through the day. Discussion: A moist and unstable air mass is in place across East TN this afternoon, especially south of I-40 where morning heating has allowed temperatures to rise into the mid 80s. This, along with increasing deep layer shear, will help maintain the approaching MCS as it reaches our area. The threat for damaging winds will exist for the Plateau and southern and central TN Valley between 4 pm and 8 pm EDT. Wind gusts of 70-80 mph will be possible. A low-end hail threat will be present as well, and an isolated tornado cannot be ruled out near the GA border, where the HRRR shows some UH tracks. Expect that a SVR Watch will be issued soon. A flooding threat will also exist due to high rainfall rates and moist ground conditions from yesterday's rainfall. As the MCS tracks east, the northern portions of it to the north of I-40 will encounter a less favorable air mass north of a boundary where cloud cover has been greater, and it should lose its strength. Additional showers/storms will likely continue overnight as we will have a jet streak and shortwave trough that will move through the region through Sunday morning. The lack of instability will keep the threat of strong to severe storms low this period. There will also be some midlevel drying, and PW values will be falling overnight to near 1 inch by Sunday afternoon, so the flooding threat should be diminishing tonight, although training cells are possible given the unidirectional winds through the column. Coverage should mainly be scattered Sunday morning, falling to isolated to nothing in the afternoon. && .LONG TERM... (Monday through next Saturday) Issued at 230 PM EDT Sat Jun 7 2025 Key Messages: 1. An approaching surface front will continue the chance for showers and storms Monday afternoon through Monday night. Chances for severe weather are marginal at this point, with isolated flooding possible due to the repeated rounds of activity over multiple days. 2. Conditions trend drier and gradually warm Tuesday through Wednesday. Discussion: An upper trough axis swings into the the Great Lakes and Ohio Valley region to kick off the new work week. Bouts of vort lobes rounding the base of the trough, diurnal heating, and an approaching surface front will continue the chance for showers and a few thunderstorms Monday. Latest guidance trends, including the NAM, suggest the frontal passage may occur more so Monday evening into the overnight hours. The NAM is often times bullish with instability and latest model derived soundings struggle to reach 750 J/kg of mixed layer CAPE among marginal bulk shear of 25-30kts. Thoughts remain that strong to severe chances are more marginal at best but we will continue to monitor trends. This has NBM PoPs trending lower for Tuesday afternoon as high pressure builds in from the northwest and the upper trough lifts northeast. We will finally be seeing a drying trend from Tuesday afternoon through Thursday afternoon, though some areas may see light activity lingering briefly Tuesday. Increasing upper level heights will promote a warming trend through this period as well. By Thursday, most locations throughout the East Tennessee Valley will be approaching the upper 80s. Roughly 5 degrees above normal for early to mid June. Shower and thunderstorm chances return late week into the weekend as surface high pressure drifts eastward over the Atlantic. && .AVIATION... (18Z TAFS) Issued at 121 PM EDT Sat Jun 7 2025 A comples of thunderstorms is moving east across northern AL, and is expected to reach CHA around 21Z. It will bring MVFR to IFR conditions with heavy rainfall, and gusty winds to around 40 kt. It should reach TYS around 23Z, but in a slightly weaker state as it moves into less unstable air. TRI will see increasing TS chances with the remnants of the system around 01Z. A moist air mass over the area tonight is expected to result in low clouds, likely at MVFR levels, gradually lifting and scattering tomorrow morning. && .PRELIMINARY POINT TEMPS/POPS...
