Area forecast discussion, May 7, 2:16 PM CDT, 3 hours 12 minutes before
Area Forecast Discussion National Weather Service Nashville TN 216 PM CDT Sun May 7 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This afternoon through Tuesday Night) Issued at 213 PM CDT Sun May 7 2023 Current regional mosaic showing The large area of showers and storms moving southward across KY. We also see a developing complex across se MO and northern AR. NBS pop data has been ticking upward and the latest Hrrr and nam nest data showing increasing confidence levels as well. So, the showers and storms across KY will impact our area beginning around 2 PM or so. The developing complex west of the MS river will be gaining strength and will intensify the existing complex as it reach our area this evening. Furthermore, latest instability parameters showing the most favorable areas across across western TN and extending into our western and northwestern areas. The higher downdraft capes are situated along the TN River at this time. The storms to our north do have an earlier history of some low end wind damage across northern KY. SPC has recently upgraded basically our entire western half from marginal to slight risk of severe. Wind and hail still look to be the likely threat beginning this afternoon and into this evening. Additionally to all of this is the potential for some localized flooding in our northwest this evening and overnight. This will depend largely on the trajectory of the aforementioned complex to our west. If this can slam into the western flank of the southward moving system, rainfall amounts will likely be enhanced. As it stands right now, 2 inches of rainfall could be rather common across our northwest by sunrise Monday. Local amounts of 3 inches can not be ruled out. Note that there is not enough confidence to hoist a flood watch. Also, understand that the short term model qpf maximums are rather isolated and across our northwest. There also appears to be some uncertainty as to the arrival of the developing MCS to our west. Moving on, the mcs pattern will remain into Monday as another system moves through. The airmass will need to refuel in order for a second round of severe to be possible. This looks somewhat questionable. We are in a marginal for now. The primary cold front should move through on Tuesday. We are not outlooked at this time. Improving conditions will begin Tuesday night. For the near term temps, it will be rather soupy and warm for early May. Lows in the 60s with highs lower to mid 80s. && .LONG TERM... (Wednesday through next Sunday) Issued at 213 PM CDT Sun May 7 2023 In the extended forecast, models are a little more bullish with leaning toward some upper ridging for our area. There is some progressiveness and the ridge looks rather narrow in scope. That said, some shortwave impacts cannot be ruled out for Thursday and Friday. We will see our shower and tstm chances climb into the chance category for that time frame. Otw, continued mild and soupy. Lows 60 to 65 and highs 80 to 85. && .AVIATION... (18Z TAFS) Issued at 1237 PM CDT Sun May 7 2023 At 18Z watching a northern MCS coming down from KY. More is expected to develop later this afternoon. This will mean ample showers and thunderstorms in and around the TAF sites through the overnight hours. Tried to time the best -TSRA with a TEMPO group for the TAF sites. CIGs/VIS are currently VFR expect this to become MVFR/IFR in and around the stronger storms. Gusty S winds turning a bit SW. && .PRELIMINARY POINT TEMPS/POPS...
