The episode as NWS HUN wrote it up.
Unstable and tropical air interacted with the remains of the circulation of former Tropical Storm Cindy to produce numerous showers and thunderstorms from late morning into the early afternoon hours. A few of these thunderstorms produced wind damage. Locally heavy rainfall of 1 to 3 inches in few spots produced brief excessive runoff and flash flooding.

Area Forecast Discussion National Weather Service Huntsville AL 1159 AM CDT Fri Jun 23 2017 .UPDATE... For 18Z TAFS. && .NEAR TERM...(Rest of Today) Issued at 946 AM CDT Fri Jun 23 2017 It will be an active day weather wise across the TN Valley as the remnants of TD Cindy begin to shift E/NE across northern TN. This morning we were dealing with a weak convergence axis that spawned some light to moderate showers out ahead of the main band of precip that remains off to the west. We are starting to see some breaks in the cloud cover and as a result temps are warming into the lower 80s across the western half of the area. The threats for today will be tornadoes and flooding. The warmer temps and slightly steeper lapse rates compared to yesterday should allow for instability to range from 300-700 J/kg. In addition to this, the strong S/SW winds out ahead of the system has resulted in a bulls-eye of 30-40kts of effective shear and helicity values upwards of 400 m2/s2. These values are very favorable rotation and any stronger storms that do form will be able to tap into these values and a few tornadoes are certainly possible later this morning into the early afternoon hours. There is a chance that a Tornado Watch might be needed for our area later today but we will continue to monitor the conditions and coordinate with SPC on that. In terms of the threat for flooding, thankfully we had a break in the rainfall overnight, which has allowed for some recovery runoff wise. However, the storms moving into the area later will be in an environment where PWATs are between 2.3-2.5 inches. These storms are going to be able to produce very intense rainfall rates over a short period of time and that combined with the now saturated ground could result in some instances of flooding. The only thing that might help to limit flooding is that storms will be moving very quickly and the intense rainfall rates may not linger over an area for very long. Plus, the heaviest rainfall is forecast to occur in NW AL, which missed out on the bulk of the rainfall yesterday. Tweaked the timing of the PoPs and modified the trends in temps a bit but otherwise the forecast hasn't changed much. Outside of the storms it will be windy with gusts of 25 to 35 mph possible. .SHORT TERM...(Tonight through Sunday) Issued at 445 AM CDT Fri Jun 23 2017 As alluded to in the last paragraph, the threat for a few strong/svr tstms will continue into the evening hrs, as the remnant low makes its way across mid TN, before merging with a cold front out of the nw and lifting into the OH Valley states. This cold front should move sewd and eventually clr the local area during the day Sat. Num/wide showers/embedded tstms well ahead of the front tonight will become more sct in nature on Sat, as rainfall eventually diminishes across the cntrl TN Valley from the nw during the afternoon hrs. Cloud cover will then begin to gradually diminish with this onset of the evening period Sat night, as a strong dome of high pressure out of the nrn Plains begins to build sewd into much of the SE region. With the passage of the front and drier air mixing into the area from the n, afternoon highs Sat/Sun look to trend slightly below normal, with highs mainly in the lower/mid 80s, while lows Sat night fall into the lower 60s given the diminishing cloud cover. .LONG TERM...(Sunday night through Thursday) Issued at 445 AM CDT Fri Jun 23 2017 At the beginning of this period, surface high pressure sprawled across the northern Great Plains will be building to the southeast. This area of high pressure with origins from the Yukon and Northwest Territories will bring a cooler than normal start - temperature wise for the Tennessee Valley. A deeper than normal eastern CONUS trough will also be in place, helping to bring the Canadian high pressure towards the southeast. After night-time lows Sunday night into the upper 50s to around 60, highs later that day will only warm into the lower 80s. Average high/low temperatures for next Monday are 90/69. Standing record low temperatures early next week were in the low/mid 50s, and will likely survive this upcoming cool period. This trend will continue into the middle of the week, with highs by Wednesday rising to the mid/upper 80s - closer to seasonable norms. Dry weather will also continue through Wednesday. During Wednesday and Thursday, the surface high should be positioned east of the region. This will of course result in winds returning from the south, helping to bring a warmer trend. Along with the heat, moisture from the Gulf of Mexico will also return. This moisture and resulting instability could lead to isolated shower/thunderstorm development next Thursday. Highs then will be in the mid/upper 80s. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1158 AM CDT Fri Jun 23 2017 A band of showers/storms associated with the remnants of TD Cindy have moved into NW AL as of 17z. These and additional storms streaming N/NE out of eastern MS will cross the TN Valley from now until around 23z this afternoon. IFR cigs/vis are possible with the storms and a brief period of LIFR might occur under the heaviest storms. Gusty S/SW winds up to 30-35kts are possible for much of the area outside of any of the storms. After storms move off to the east there is some uncertainty in whether or not showers/storms will move back into the area as a cold front drops in from the NW. Have kept precip out of the TAFs for now but switched the wind direction up to the NW closer to 12z Saturday morning. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.

Hazardous Weather Outlook National Weather Service Huntsville AL 447 AM CDT Fri Jun 23 2017 ALZ001>010-016-TNZ076-096-097-240100- Lauderdale-Colbert-Franklin AL-Lawrence-Limestone-Madison-Morgan- Marshall-Jackson-De Kalb-Cullman-Moore-Lincoln-Franklin TN- 447 AM CDT Fri Jun 23 2017 This Hazardous Weather Outlook is for north Alabama and portions of southern middle Tennessee. .DAY ONE...Today and Tonight... Thunderstorm coverage will increase across the Tennessee Valley into the evening, as the remnants of Tropical Depression Cindy approach the area. Some of the storms could become strong to severe in intensity, with damaging wind gusts and a few brief tornadoes the main threats. In addition, very high amounts of moisture associated with this system could result in very heavy rainfall, and a risk of flooding or flash flooding. Additional rainfall totals through late tonight should range from 1 to 1.5 inches, with locally higher amounts possible. .DAYS TWO THROUGH SEVEN...Saturday through Thursday... Thunderstorm coverage and intensity will diminish during Saturday, and should end Saturday evening, as a cold front moves across the region. Isolated thunderstorm chances return next Thursday, as Gulf moisture and instability return to the Tennessee Valley. .SPOTTER CALL TO ACTION STATEMENT... Activation of storm spotters and emergency management personnel may be needed today and tonight. RSB
