Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Lake Charles, LA wrote its last area forecast discussion before this severe thunderstorm warning went out at Oct 27, 3:09 PM CDT, 1 hour 20 minutes earlier.

Area forecast discussion, Oct 27, 3:09 PM CDT, 1 hour 20 minutes before
Area Forecast Discussion
National Weather Service Lake Charles LA
309 PM CDT Wed Oct 27 2021

.DISCUSSION...

.SHORT TERM [Today through 12Z Saturday]...

A very robust weather pattern is ongoing across the CWA this
afternoon as a strong low pressure system moves across the Lower
MS River Valley. Across the western half of the CWA, rain is
coming to an end this afternoon and skies are beginning to clear.
On the other hand, the eastern half of the CWA, especially across
Acadiana, will continue to see strong thunderstorms through the
next few hours as this storm system continues to propagate
eastward. Looks like the potential for tornadoes has largely died
off with the main concern continuing to be damaging straight line
winds along and ahead of this squall line. The squall line will
finally move out of the CWA through the next couple of hours,
with the trailing stratiform rain coming to an end through
evening hours shortly thereafter. Once the rain comes to an end
this evening dry weather can be expected through the end of the
short term period.

Tonight into tomorrow, strong northwesterly flow in the wake of
today's cold front will bring a cooler and drier airmass into the
region. Temps will fall through the evening and overnight hours,
with lows expected to bottom out in the mid to upper 50s tomorrow
morning. Tomorrow and Friday, afternoon highs will top out in the
upper 60s to mid 70s, amid sunny skies, while lows will fall into
the mid 40s to low 50s overnight. Only concern through the next
couple of days will be strong gusty winds as the pressure
gradient overhead tightens behind the departing low pressure
system. Sustained winds around 15-20kts and gusts to around
25-30kts can be expected tomorrow especially through the
afternoon. Winds will remain elevated into Friday, before
gradually calming Friday night into the weekend.

17

.LONG TERM [Saturday through Wednesday]...

As we start the extended period, the area will remain under the
influence of nwrly flow aloft behind the departing mid/upper-level
low, while sfc high pressure gradually builds ewd over the wrn Gulf
Region. The combo of all this will maintain our dry/cooler
conditions through the weekend with near-seasonal lows in the
40s/50s and highs in the 70s.

By Monday, the high is progged to push ewd past the forecast area,
allowing a return flow to re-develop. The increasing srly flow will
allow a warmup to commence with temps pushing 80F that afternoon. A
weak disturbance passing aloft will likely increase cloud cover, but
forecast soundings indicate insufficient moisture to allow for any
convective development. This pattern looks to continue into Tuesday
at this time.

Rain chances return to the area for Wednesday as a mid-level
shortwave pushing ewd toward the Mississippi Valley drags another
front toward the region, while forecast soundings indicate better
moisture in play. The enhanced cloud cover and precip should hold
temps back a little with highs expected to run in the mid 70s for
the bulk of the forecast area.

25

&&

.MARINE...

Strong gusty winds and elevated seas will be a concern across all
marine zones through the end of the week as the pressure gradient
overhead remains tight. Sustained winds around 20-25kts overnight
tonight will increase to around 25-30kts tomorrow, with
accompanying gusts upwards of 40kts possible. At the same time,
seas around 5-8 feet with higher swells especially in the beyond
20nm waters will be possible. Winds will still be very breezy on
Friday but will finally begin to relax Friday evening into early
Saturday, falling to around 10kts by Saturday afternoon.
Northwesterly flow will shift north, northeast and eventually
eastward by the end of the weekend as high pressure settles over
the SE US.
