Numerous roads will be flooded and impassable. Rivers and creeks will rapidly rise and overflow their banks. PRECAUTIONARY/PREPAREDNESS ACTIONS... Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. && $$

The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Morristown, TN wrote its last area forecast discussion before this flash flood watch went out at Mar 26, 4:06 PM EDT, 3 hours 4 minutes earlier.
Area forecast discussion, Mar 26, 4:06 PM EDT, 3 hours 4 minutes before
AREA FORECAST DISCUSSION National Weather Service Morristown TN 406 PM EDT Fri Mar 26 2021 .SHORT TERM (Tonight and Saturday)... Our fair weather will not last long. Frontal boundary well to our south has brought in plenty of sunshine, but it will lift northward rapidly and bring a new round of rainfall with it for Saturday. Mesoscale indications support a threat of heavy precip Saturday in a band oriented west to east from Middle TN to near Knoxville. There is low confidence on the exact placement of this forecasted precip, as well as the amount. Don't be surprised (if the heavy rain forecast holds firm) if a Flood Watch is issued tonight. But will have to look upon further model updates and coordinate with surrounding offices. There is also the issue of the warm front's progress. Haven't the last two stalled to our south longer than anticipated? Will this one? Again, the confidence in these details is a bit low. Even so, our soils are quite saturated already, and after whatever rainfall we receive Saturday, a second round of potentially heavy rain will occur with the main cold frontal passage late Saturday night and Sunday. Those details follow below. GC .LONG TERM (Saturday Night through Friday)... Key Messages: 1. A line of strong to severe storms will cross late Sat night into Sun morning, but the exact timing is low confidence. 2. The biggest impact will be areas of flooding across the Plateau and S Valley. 3. The storms will be weakening as they cross, so the areal coverage of severe weather is low confidence, but strong dynamics and at least some surface instability pose a threat for pockets of damaging winds, small hail, and an isolated tornado, mainly W of I-75. 4. Drying out Sun afternoon through Mon with cooler temps by Mon. 5. Warming trend again Tues and Wed with periods of showers and thunderstorms, but not a washout. 6. Much colder Thurs into Fri with temps 10-15 degrees below normal. Discussion: Saturday Night and Sunday Morning... Overview A strong northern stream mid/upper trough will progress through the Mid MS Valley Sat night and through the Great Lakes and OH Valley Sun with an attendant surface low deepening to about 990 mb as it lifts NE into Ontario Province. This will force a strong cold front through the TN Valley and S Appalachians late Sat night through Sun morning. Guidance is in agreement that the warm front will at least make it into NE TN Sat night with a tongue of surface based instability working into the Plateau, most of the Valley, and SE TN/SW NC. However, as we have seen in recent events, the warm front can be slow to move off the Plateau and fully lift NE through our region, especially if there are showers ahead of it and some CAD east of the Appalachians, so how quickly the surface based instability can work NE (and how far) remains in question. The system will be dynamic with a 125-130+ kt upper jet rounding the base of the aforementioned northern stream trough across KY and the OH Valley. The right entrance region of this jet max will enter the S Appalachian region late Sat night with the associated strong upper divergence creating large scale forcing for ascent and strong frontogenesis ahead of the cold front. In response to this upper forcing, a southwesterly low-level jet will also strengthen to 60 kts late Sat night into Sun morning. Convective Evolution and Timing The dynamics and thermodynamics will support a line of strong to severe convection propagating into the region from Middle TN. The exact timing that this line will reach the Plateau is low confidence with the NAM, WRF, and other CAMs and HREF guidance differing from pre-dawn hours of Sun to mid morning/early afternoon Sun. The greatest chance of severe weather will be W of I-75 where surface instability will more likely be in place (a few hundred joules of surface CAPE), but with the late night/early morning timing, expect storms to gradually lose their punch as they move E. With this being said, areal extent of severe weather is uncertain, but strong 60-70 kt deep layer shear and 40 kt low-level shear will pose a risk of damaging winds if the line can tap into the available surface CAPE. Hail CAPE does not look too impressive, but mid level LR around 7 C/Km could support some small hail. Due to the linear nature of the convection, generally weakening state, and high LCL heights, tornado potential is low, but an isolated tornado or two cannot be ruled out since 0-1 Km SRH is progged to be over 300 m2/s2. Expect the storms to weaken as they move E of I-75 with much less severe potential in those areas Sun morning. Rainfall Amounts and Flooding The far more certain aspect of this forecast is that there will be some flooding. Heavy rains of generally 1-3 inches from the S Plateau through the S Valley into SW NC yesterday saturated the ground with a couple of rivers still above flood stage. The strong low-level jet Sat night into Sun will transport anomalous moisture northward with IVT progged to reach the 97th percentile to possibly max daily climatological value by Sun morning leading to PWATs of 1 to 1.5 inches which is around the 99th percentile. This will lead to heavy rainfall rates as the squall lines comes through. The good news is that the line will be progressive with little to no training expected, but the above mentioned southern areas have low FFG's due to the wet antecedent conditions, so areas of flooding can be expected. Mountain Winds As the low-level jet strengthens Sat night, expect at least advisory level wind gusts in the E TN mountains and foothills. The flow will be more SW than ideal across the terrain, and the strongest jet (60 kts) holds off until Sun morning, so held off on a High Wind Watch for now with that being period 4. The higher peaks of the Smokies will likely see gusts over 50 kts by Sun morning for a few hours. Sunday Afternoon through Monday... Drier air will quickly fill in behind the cold front Sun afternoon, so dropped PoPs from W to E. Surface high pressure and NW flow on the backside of the exiting mid/upper trough Sun night and Mon will keep the region cooler with lows falling into the mid 30's/low 40's Sun night and highs in the low 60's Mon. Areas of frost are possible from the N Plateau through NE TN/SW VA Mon morning. Monday Night through Friday... A mid/upper ridge will amplify over the eastern CONUS Mon night into Wed as a deepening longwave trough moves from the Rockies into the Plains. This will rebound highs into the upper 60's/low 70's Tues and Wed. A lead shortwave impulse will bring scattered showers Mon night through Tues morning, followed by a better chance of both showers and thunderstorms ahead of a strong cold front as the longwave trough moves E on Wed. Behind this front Wed night through Fri, an unseasonably deep mid/upper trough will dig into the eastern CONUS with temps 10-15 degrees below normal. Any lingering showers could mix with snow showers in the higher elevations late Wed night into early Thurs before ending as drier air moves in during the day Thurs. Garuckas && .AVIATION... 18Z TAF DISCUSSION. VFR will prevail most of the night. But moisture will return from the south. Late in the period, MVFR cigs will start to build into CHA, with rain arriving around 12Z, and spreading northward through midday. GC && .PRELIMINARY POINT TEMPS/POPS...
