What happened

The episode as NWS HUN wrote it up.

Heavy rainfall occurred across the entire NWS Huntsville County Warning area, as well as damage from thunderstorm winds and a few tornadoes.

While heavy rainfall reports were spread out across the CWFA, the most significant flash flooding occurred in Fort Payne and surrounding areas in Northeast Alabama.

Intense rainfall of 6-6.5 inches fell in DeKalb County along Big Wills Creek.

A new Flood of Record crest of 17.94 feet occurred, surpassing the old Flood of Record (14.36) by a whopping 3.5 feet! More than 50 roads were shut down, with extensive flooding that occurred on Hwy 35 leading up to the Hwy 35/I459 interchange.

.NEAR TERM...(Rest of Today)
Issued at 907 AM CDT Sun Apr 12 2020

No major changes to the previous forecast. SPC did expand the
moderate risk category farther north including most of NW AL as well
as the Huntsville metro area. Showers/thunderstorms over NW AL will
continue to lift north and east the morning, but given SFC
temps/dewpts in the 50s not expecting these storms to exceed severe
criteria.

Previous discussion:

Not a significant severe threat with the morning showers and
thunderstorms as the stable layer near the surface will inhibit
downdrafts from reaching the surface, and updrafts from tapping into
the low-level wind shear. As the warm front continues to slowly move
northward, however, we will see that inversion near the surface
become shallower and shallower which will slowly increase the
potential for gusty winds and hail.

During the day today, our hi-res convective allowing models still
don't seem to be in agreement on how far north the warm front gets
before it stalls. Most of these models really tend to support the
theory that the showers through the morning hours will help to hold
the warm front mostly south of the Tennessee Valley until the cold
front gets closer during the evening hours. During the day, before
around 5-7 pm, the primary threats will likely be wind and hail.

.SHORT TERM...(Tonight through Monday Night)
Issued at 345 AM CDT Sun Apr 12 2020

Now for the tonight period. Most of the convective allowing models do
actually lift the warm front north through at least Northeastern
Alabama, if not all of northern Alabama and southern Middle
Tennessee. This will be out ahead of the main cold front. The HRRR
appears to be the main outlier with probably our "worst-case"
scenario, lifting the warm front north of the AL/TN border during the
afternoon. The earlier this warm front lifts north, the more
instability the cold front will have to work with to generate
stronger storms across the Tennessee Valley. This would probably mean
some form of QLCS feature develops with bowing segments producing
damaging winds and embedded circulations possibly generating
tornadoes. The "best-case" scenario, on the other hand, doesn't
have the warm front lift north into the Tennessee Valley really at
all, which keeps most of the severe weather with the more dynamic
cold front to our south. Models showing this scenario still clip Sand
Mountain with a stronger storm or two, but leaves NW Alabama pretty
much out of the severe thunderstorm threat. We will have to watch the
warm front very closely through the day today. The likely scenario
will probably be somewhere in between.

We have a second frontal boundary that is more associated with the
base of the upper-level trough and a secondary surface low
developing along the occlusion. This may bring one final line of
showers and thunderstorms through just behind the stronger cold
front around 10 PM to 2 AM. This could possibly be another round of
severe thunderstorms. Main question with this line will be will the
environment be "tapped out" by the time it arrives? Will the strong dynamics
with the cold front aided by the upper-level trough help these storms
stay strong and overcome a lesser amount of instability? There will
still be a significant amount of low-level and bulk shear. At this
time it's hard to say what to make of this second cold front. All I
can say at this point is continue to be weather aware going into
Sunday night.

Now for winds. This dynamic system generates a fairly strong pressure
gradient out ahead of the surface low, setting up across most of
Alabama and Middle Tennessee. This will mean gusty southerly winds
are expected to develop with the strengthening pressure gradient this
afternoon through late tonight. The gradient really doesn't relax
until the base of the upper-level trough swings through, which might
not be until after midnight tonight. In Northeast Alabama, the
gradient might not relax until as late as 7 AM Monday morning. We
have a wind advisory out until midnight tonight, however this may
need to be extended in NE Alabama depending on how the low actually
tracks.

The cooler air finally arrives behind the second cold front after
midnight Monday morning. Showers and Thunderstorms will be moving off
to the east, and skies will be clearing. Northwesterly winds, while
they will be bringing in cooler air, the friction generated by wind
will help keep temperatures from plummeting Monday morning. Lows will
probably only drop into the low-to-mid 50s. Highs Monday afternoon
will probably only get up into the low-to-mid 60s under sunny skies
with northwesterly winds gradually weakening through the afternoon
and evening hours.

.LONG TERM...(Tuesday through Saturday)
Issued at 345 AM CDT Sun Apr 12 2020

The medium range models continue to show an unseasonably cool
weather pattern early next week, followed by a modest warming trend.
Continental scale trough will continue to dominate the CONUS, with
the southeast region remaining in a west-northwest flow regime as a
result. An upper trough axis will bring mostly mid level clouds and
perhaps a few showers Tuesday Night. However, most precip will be
well southeast along the frontal system from the central Gulf Coast
through the Carolinas. Then, dry weather is foreseen through Friday
with lows in the u30s Wed-Thu mornings. Highs Wed will be in
u50s-a60, with 60s on Thu. As high pressure shifts off the southeast
coast on Friday, southerly flow will bring modest warm advection and
highs closer to normal with u60s-l70s. A fast moving frontal system
will arrive either Friday night or Saturday (variance in the models).
This will bring only very light precipitation at most for our area
with deeper moisture and convection remaining nearer to the Gulf
Coast.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1227 PM CDT Sun Apr 12 2020

Several rounds of rain and thunderstorms are expected during the TAF
period. The first round at the start of the period will bring rain
and TSRA through 20z. After a brief break in thunderstorms, a
stronger band of thunderstorms will move from SW to NE between 23z to
03z. Gusty winds up to 35 kts is possible along with CIGS and VSBY
reductions into IFR criteria. Have also included wind shear in the
TAF with 50 kts not too far above the surface. Gradual improvement
overnight with a return to VFR by sunrise.

The tornado continued from Etowah County west of Highway 431, south of Denson Avenue. It quickly intensified to its peak strength as it crossed Highway 431 and plowed through a neighborhood north of Roden Road. Nearly every single home (dozens) in this neighborhood experienced some degree of damage. The most intense damage was noted from two separate single family homes. The first home, with the most devastating damage, was completely destroyed and was mostly taken off its foundation with only two small interior rooms remaining, where the residents took shelter. It was noted however that the anchorage system for the home appeared to be non-existent with no bolts observed to the foundation crawl space piers. The second heavily damaged home on Lee Avenue, experienced a collapse of exterior walls, likely occurring after the roof was taken off. The tornado continued on an east to northeast track across and along Bethsaida Road causing numerous trees to snapped or be uprooted. Several houses appeared to have had shingle roof damage. The tornado continued into DeKalb County.
