The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Huntsville, AL wrote its last area forecast discussion before this special weather statement went out at Aug 19, 6:57 PM CDT, 59 minutes earlier.
Area forecast discussion, Aug 19, 6:57 PM CDT, 59 minutes before
Area Forecast Discussion...UPDATED National Weather Service Huntsville AL 657 PM CDT FRI AUG 19 2016 .UPDATE... For 00Z TAFs. && .DISCUSSION... (Issued 356 PM CDT FRI AUG 19 2016) A moisture plume extending from northern Mexico to the southern Mid Atlantic and Carolinas continued a feed of deep moisture across the southern states. This moisture and daytime driven instability has set the stage for scattered to numerous showers and t-storms across parts of the Tennessee Valley. With precipitable water amounts ranging in the 1.8 to 1.9 inch range, some of the showers and storms have produced locally very heavy rainfall. One has produced flash flooding in parts of central DeKalb county. Given the high amounts of moisture into the mid atmosphere, not as much lightning has been realized with most of the heavier showers. Additional cloud cover, showers and deeper moisture have helped reduced temperatures across the region compared to the past few days. Highs so far have risen into the mid to upper 80s in the rain-free spots, and in the low/mid 70s in/near shower activity. More passing upper level systems (mainly to our north and south) could help more showers/storms form this evening. Night time cooling and a more stable atmosphere should result in convection fading later this evening and during the late night. Places that receive a good wetting rains and/or have less cloud coverage could be affected by fog near daybreak. Given that any fog formation will be patchy - did not put it in the forecast. More daytime heating in a moisture atmosphere should bring more widespread shower/thunderstorm development during Saturday. Model indicated precip water amounts in the 1.9 to 2.2 inch range of course means locally heavy rains, along with a potential for water ponding or flooding cannot be ruled out. Forecast soundings from the NAM/GFS look similar to today's (with the GFS a bit drier in the mid levels), thus somewhat greater odds of gusty winds in the ~40 mph range and more lightning production in the heavier showers. The approach of a cold front will keep high rain chances going Sat evening. The front should move in a NW-SE manner across the region during Sunday, ending rain from north to south during the day. Dry weather with slightly cooler than seasonable temperatures (highs in the mid/upper 80s) will start a new week. High pressure should build southward from the northern plains, reaching the Mid Atlantic by the middle of next week. The front south of the region will return northward after midweek, bringing more shower chances back to the area. RSB && .AVIATION... For 00Z TAFs: Oscillating VFR to IFR conditions are expected for portions of N AL (especially near KHSV) for the next couple of hours (through 02Z) as TSRA/SHRA continue at times. Then, may have more isolated to scattered TSRA/SHRA btwn 20/02Z-09Z as another upper level disturbance moves across the region. In addition, fog formation and possibly MVFR/IFR cigs may occur after 20/09Z. sl.77 && .HUN Watches/Warnings/Advisories... AL...NONE.
