Area Forecast Discussion
National Weather Service Quad Cities IA IL
1221 PM CDT Wed Jul 14 2021

...AVIATION UPDATE...

.SYNOPSIS...
Issued at 210 AM CDT Wed Jul 14 2021

All was quiet across eastern Iowa, northwest Illinois and far
northeast Missouri early this morning. Other than an isolated rain
shower over northwest Illinois, skies were largely clear to partly
cloudy thanks to a weak ridge of high pressure overhead.
Temperatures were warm thanks to renewed southerly flow, with
temperatures as of this hour in the upper 60s to low 70s area wide.

Off to the west, showers and storms were ongoing from South Dakota
to Nebraska; fueled by a strong LLJ and shortwave centered over
southeast Montana. Hints of a developing surface low were apparent
on MSAS pressure fall maps across northeast Colorado. These features
will all come together and impact our weather heading into the short
term period.

&&

.SHORT TERM...(Today through Thursday)
ISSUED AT 210 AM CDT Wed Jul 14 2021

[Key Messages]

*Threat for severe thunderstorms today and Thursday as cold front
and shortwave slowly move through the area

*All severe hazards possible including torrential rainfall
which could produce flash flooding

[Discussion]

A busy short term period is expected across all of eastern Iowa,
northwest Illinois, and far northeast Missouri. Showers and storms
currently in place from South Dakota to Nebraska will work their way
east, eventually finding their way to northeast Iowa, southeast
Minnesota and southwest Wisconsin. These should be elevated for the
majority of the duration as they feed off off a fairly potent and
moisture filled eastward moving 30-40 kt LLJ.

These storms are progged by the CAMs to reach that area during the
midday hours (11am-2pm), and should have decent coverage to them as
the LLJ is forecast to not lose too much strength despite the
increasing daytime heating. Storms are likely to impact areas mainly
along and north of the Hwy 20 corridor before eventually moving out
of the area by the mid-afternoon. These could become strong as they
move into an area untapped with some heating and become surface
based, but this threat is likely to remain more into southwest
Wisconsin. This activity should leave an outflow boundary behind
across the area, which will be the focus for additional storm
development during the late afternoon and evening.

While clouds are expected to increase across the area thanks to the
morning convection, they should not pose much of a hindrance to
afternoon/evening development. This is due to the approaching
shortwave in northwest flow aloft, with some pockets of CVA due to
move into the area during this time frame. Forecast soundings show
mid-level lapse rates steepening in response to the approaching
shortwave, and when combined with added convergence from the remnant
outflow boundary, approaching surface front and deepening surface
low moving into Iowa this should be enough to induce late afternoon-
evening storm development.

Think where that outflow boundary sets up will be crucial to where
severe weather is most favored across our area. As is typical in
most of these situations, CAMs are not in good agreement on
placement of the late afternoon/evening formation in the latest runs
due to disagreements on handling of the morning MCS activity. But
there are a couple of potential scenarios:

1) There is a signal in some CAMs that the outflow boundary sets up
around the Hwy 20 to Hwy 30 corridor, in a zone that will be
relatively uninterrupted by morning storms. If this were to hold,
potential would be there w/ the increased convergence of discrete
storms to start (latest runs of the HRRR showing this potential).
Surface instability forecast to climb into 2000-3000 J/kg range with
increasing shear due to the approaching shortwave and LLJ would
favor all severe hazards to start. Eventually, developing storms
would merge and pose more of a damaging wind and torrential rain
threat into the evening hours as cold pool processes take over.

2) With the deepening low pressure to our west, there is an added
option that the leftover outflow boundary gets shunted back north by
strengthening southerly flow near to or just north of the Hwy 20
corridor. This would favor more discrete storms and the favored
tornado/hail threat back into northern and northeast Iowa, with our
area more likely to be impacted by damaging winds and torrential
rain during the late evening. This is the scenario I'm leaning
more towards with this package.

Therefore, much of today's severe threat is deeply tied to the
mesoscale and will likely undergo more changes as the morning
progresses. As of early this morning, the Storm Prediction Center
maintains a Level 3 (enhanced risk) for severe thunderstorms
generally along and north of Hwy 30, with a Level 2 (slight risk)
north of a line from Sigourney IA to Dixon IL.

Eventually, the severe threat should wane overnight as precip
transitions into a more typical MCS setup for the area. Activity
should focus more on the convergence zone of the LLJ and southward
moving cold front, which is forecast to reach the northwest CWA
during the early morning Thursday. The threat will then turn to
torrential rain, as the added convergence of the LLJ/front a
moisture filled PWAT feed from the south focus on the area.

There is good news and bad news. The good news, is that area FINALLY
gets some needed rain. However, it's going to be falling all at once
and quickly, given the deep warm cloud depths and high amount of
moisture. Because the soil is hard and not as permeable due to the
drought conditions, there is likely to be more runoff than not,
making for a higher potential for flash flooding concerns. This is
reflected well in the WPC excessive rainfall outlook, which paints
areas north of I-80 in a Level 2 (slight risk). Given CAM
uncertainty of where the favored convergence zone sets up, decided
against a flash flood watch for the level 2 area at this time.
However, this will be further analyzed later.

Thursday is likely to be a raw day for most of us as the cold front
slowly moves through the area. The persistent LLJ will add
convergence along the front, meaning POPs are going to remain at
"likely" or higher for most of us during the day. Late in the
afternoon, there is potential for a new round of strong and severe
storms, with a focus on I-80 south. The Storm Prediction Center
maintains a Level 1 (marginal risk) for this area in their Day 2
outlook. This will need to be watched closely, as the stronger lift
with the shortwave and jet equatorial entrance region will be
overhead and will work with the front. Debris from earlier activity
is the main thorn in this potential as it could hinder some
development, but think the added lift could fire activity
regardless. All severe hazards will be in play, especially potential
for flash flooding given this area has been hit pretty hard w/
rain in recent weeks.

.LONG TERM...(Thursday Night through Tuesday)
ISSUED AT 210 AM CDT Wed Jul 14 2021

Key messages:

1. Change in pattern to a more quiet weather period.
2. Temperatures in the 80s return for the weekend.

Discussion:

Largescale ridging is forecast to move into the area at the beginning
of the period.  This ridging is forecast to last through the period,
bringer quieter weather with it.  Guidance has one of the NW flow
waves become cutoff south of the area.  This cutoff low may lead to
chances for pops just south of the area.  The placement of this low
could change and with it our chance for precip in the extended.

Friday looks the 'best' day for precip in the extended with the cold
front just south of the area.  While we will be north of the surface
front, a NW flow wave along with the left entrance region of the jet
could be enough for some showers across the area.  QPF looks like
and should not be all that impactful across the area.

From a sensible weather aspect, temperatures are forecast to be in
the 80s with current blend Tds just below 70.  With the corn, these
Tds may be too low.  Summer heat and humidity look to be the main
story next week.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon)
ISSUED AT 1214 PM CDT Wed Jul 14 2021

Showers and thunderstorms are ongoing as of 18Z, impacting near
DBQ and MLI. These will continue through 20Z, with a break until
this evening. These storms are bringing along MVFR conditions,
with IFR in some of the heavier storms. Also, some of the storms
this evening can lead to gusts up to 50 KTs and hail. Winds will
stay from the south through tonight and tomorrow morning, with
gust upwards to 20-25 KTs. Again tomorrow, widespread showers and
storms are expected.
