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 Quad Cities, IA wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 14, 12:55 AM CDT, 1 hour 49 minutes earlier. Its key messages:

  • Scattered severe storms south of I-80 early this morning. A few strong to severe storms could redevelop this afternoon, mainly in the counties south of I-80.
  • Turning much colder late in the weekend with the potential for snow showers.
  • A warming trend is on tap for next week.

.MESOSCALE...
Issued at 1245 AM CDT Thu Mar 14 2024

A Severe Thunderstorm Watch continues across the southern CWA
through 6 AM this morning. The northern periphery of warm air
advection (WAA) aloft will continue to nose into the southern
CWA through the early morning, with slow-moving, regenerating
thunderstorms. Embedded MCVs and one stronger short wave to pass
near the Missouri/Iowa border region in the pre-dawn hours, will
act to keep some severe threat going through the night along
with a locally heavy rain threat where storms line up more
west-to-east. The flash flood threat though still looks on the
lower end due to primarily drier antecedent conditions.

In terms of the severe threat, hail will remain the primary
threat, with a good balance of deep layer shear (40 kt) and
MUCAPE (500-1500 J/kg). If any semi-organized storms from
northern Missouri can make it into the southern forecast area,
the boundary layer stability looks like it may be fairly shallow
based on observational trends, so isolated stronger winds might
be a concern if that occurs.

&&

.SHORT TERM /THROUGH TONIGHT/...
Issued at 301 PM CDT Wed Mar 13 2024

Other than some isolated showers in northwest Illinois, dry
conditions will be seen across the area through sunset. Attention
then turns to tonight.

Storms will initiate along the warm front across northern Missouri
during the evening with rain lifting north across the area
overnight.

At the same time flow coming off of Lake Michigan will be pushing
drier air to the west. This drier air will initially delay the
arrival of rain into the area until the late evening and overnight
hours and main push the stronger storms further to the south.

Right now the better risk for strong to severe storms looks to be
along and south of an Ottumwa, IA to Galesburg, IL line. The primary
risk is hail with damaging winds a secondary risk. A storm that
rides the warm front or is to the south and east of the low center
would pose a risk for a brief spin up tornado. If this were to occur
(which is under a 2 percent chance), areas south of a Keosauqua, IA
to Macomb, IL line would be favored.

On Thursday a widespread rain should be across most of the area at
sunrise. Depending upon the track of the surface low, the severe
risk 'may' pivot to the north between 6 and 10 AM putting a risk of
severe storms south of a Princeton, IL to Aledo, IL to Kahoka, MO
line. The main risk would be hail with damaging winds a secondary
risk.

By late morning the overall severe risk from the first round of
storms will end with the potential for rain ending from west to east
as well. The far northern and northwest parts of the area may see a
cold rain continuing through late morning and into the afternoon.

Boundaries left over from the overnight storms and the approaching
cold front will then provide the focus for re-development in the
afternoon.

Right now the overall timing of secondary storm development looks to
be early afternoon from northeast Missouri into western Illinois.
The window for any severe risk has narrowed, running from 3 to 7 PM
and mainly south of a Princeton, IL to Memphis, MO line.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Issued at 301 PM CDT Wed Mar 13 2024

Thursday night
Assessment...low to medium confidence

How storms develop and evolve Wednesday night into Thursday morning
will dictate how long precipitation remains across the area Thursday
night.

Right now the model consensus has a 40-50 percent chance of rain
across the entire area. However, there are newer runs of the very
short term models that suggest much of the area could remain dry
Thursday night. By late Thursday night mainly dry conditions should
be seen across the area.

Friday through Saturday night
Assessment...high confidence on dry conditions

The model consensus has dry conditions for the area with
temperatures initially above normal. A clipper system will move
through the Great Lakes and pull a modified arctic front through the
area on Saturday.

Very windy conditions will develop Saturday with gusts up to 40 mph
likely. The wind combined with the dry conditions will result in a
elevated fire risk across the entire area. The windy conditions will
continue Saturday night which will push wind chills into the teens
and lower 20s by sunrise Sunday.

Sunday and Sunday night
Assessment...high confidence on windy conditions

Windy conditions will continue across the area on Sunday as the core
of the cold temperatures aloft moves through the area. An associated
upper level disturbance will provide enough forcing for flurries or
even snow showers for areas generally east of the Mississippi and
north of I-80. Given the warm ground temperatures, only a localized
dusting of accumulation would be possible on grassy and elevated
surfaces in the strongest snow showers.

Monday through Wednesday
Assessment...medium to high confidence on a warm trend. Medium
confidence on dry conditions

The current model consensus has dry conditions across the area with
a warming trend through mid-week.

However, the CMC and ICON deterministic runs bring a clipper system
into the Midwest with snow. The CMC is further west which places the
snow over the area while the ICON model indicates southeast
Wisconsin and northeast Illinois. Interestingly the GFS/ECMWF
deterministic runs have no clipper system.

Interestingly there are some members of the ensembles of the
GEFS/CMCE that lend support the the CMC/ICON deterministic runs but
most of the ensemble members are dry.

&&

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1245 AM CDT Thu Mar 14 2024

Primary concerns with aviation are thunderstorms early this
morning, mainly prior to daybreak, and then IFR conditions a
good part of today for most of the TAF sites.

Showers with at least embedded storms will continue to expand
northeast through the early morning. Some of these will produce
temporary IFR visibility, although thunder should become a
little more spotty toward CID and especially DBQ (where
confidence in any TSRA is low). Shower coverage looks like it
will diminish between 12Z and 17Z, however areas of
drizzle/light rain with spotty showers are becoming more
probable. The regime is favorable for IFR ceilings to develop
and possibly IFR visibility, especially if drizzle is present.
BRL will likely remain south of these lowest conditions, but the
other TAF sites should be in them, with highest confidence at
DBQ where LIFR ceilings are favored at times.

As the weather system bringing the precipitation tracks across
the Missouri/Iowa/Illinois border region this afternoon,
scattered storms may develop near BRL. Otherwise, rain showers
are expected to the north, although confidence in what the
coverage and duration of this rain will be is uncertain.
Nonetheless, IFR ceilings are likely to persist and spread
southward to BRL through the evening hours.
