The episode as NWS BMX wrote it up.
A slow moving cluster of thunderstorms along the I-20 corridor east of I-65 produced localized heavy rainfall.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Birmingham, AL wrote its last area forecast discussion before the first event at Jun 10, 5:58 PM CST, 3 hours 32 minutes earlier.
Area Forecast Discussion National Weather Service Birmingham AL 658 PM CDT Sun Jun 10 2018 .UPDATE... Evening Update and 00Z Aviation. && .SHORT TERM... Central Alabama sits in a weakness int he upper ridge. 850-300mb mean winds are very weak and were west to northwest. Due to the weak winds through the layer, the storm motion is relying more on the outflows and propagation with them. Therefore, we have storms moving northward, eastward and southeastward. The overall slow movement will lead to brief torrential rain under the heavier cells. Mean relative humidity is higher both north and south, but the boundary convergence should allow for scattered development the next few hours. Downdraft CAPE is high while CAPE is also high, therefore a few wind gusts into the 40-50 mph range are possible. CAPE aloft will also allow for some small hail. The late afternoon start was due to the mixing up of the atmosphere from yesterdays storms. 75 Previous short-term discussion:Through Tonight. Much less activity this afternoon probably due to convective overturning from yesterdays storms. One area to watch is a convective line across Etowah and Cherokee counties that is tracking southeast into an airmass that is fairly unstable. Do not expect explosive development that occurred after sunset on Saturday, but mostly isolated storms weakening throughout the evening hours. 58/rose .LONG TERM... Monday through Saturday. Central Alabama will remain within a broad weakness in the subtropical ridge through the extended period with overall weak flow and no significant air mass changes. Temperatures will run near to a couple degrees above seasonal averages. Low- level ridging over the northern Gulf will prevent prolonged direct onshore flow, but sufficient moisture will still be in place for daily scattered to at times numerous showers/storms especially during the afternoon/evening in a typical summertime pattern. Some strong storms with gusty winds will be possible each day as well. Overall there aren't any big synoptic features to base the PoP forecast on, as mesoscale boundaries and weak waves/MCVs aloft will be the main influence. For Monday, could see slightly better coverage in the far eastern counties near a departing upper trough axis and in the southern counties where PWATs approach 1.9 inches. Multiple models actually try to show an uptick in activity Monday night after midnight in the southern/western counties, possibly due to an MCV, and will keep chance PoPs going overnight in those areas. PWATs continue to to creep up to around 1.9 to 2.0 inches Tuesday/Wednesday, with likely PoPs in some areas both days. The GFS continues to not have any support from the ECMWF or its ensembles with a tropical system forming in the Gulf late next week, and therefore continues to look like an extremely unlikely solution. The ECMWF does indicate deep tropical moisture moving into TX/LA towards the end of the period, with more typical summertime moisture/rain chances continuing for Central Alabama. 32/Davis && .AVIATION... 00Z TAF Discussion. Generally VFR forecast outside convection and brief patchy fog around daybreak. No atmosphere change and we remain situated in a weakness in the upper ridge. This will keep the same general pattern going into Monday. Therefore, leaned on persistence with this forecast. Started off a few terminals with VCTS as the convection will probably last another few hours before diminishing. Patchy fog will once again be around the area and hit the most likely suspects. Thunderstorms are expected again Monday afternoon and added PROB30 all locations. Gusty winds and torrential rain possible under the storms. Winds remain rather light and out of the southwest. 75 && .FIRE WEATHER... Scattered to numerous showers and storms expected each afternoon through mid week. Cannot rule out at least isolated coverage during the overnight hours. Light fog is possible each morning, and most likely will be near locations that receive rainfall the previous day. RH values remain above critical values. There are no fire weather concerns at this time. && .PRELIMINARY POINT TEMPS/POPS...
