Area Forecast Discussion
National Weather Service Quad Cities IA IL
314 AM CDT Sat Jun 25 2022

.SYNOPSIS...
Issued at 314 AM CDT Sat Jun 25 2022

Thunderstorms with heavy rain continued to expand across portions
of eastern Iowa during the early morning hours. Through 3 am, the
heaviest rainfall amounts around 3 inches had occurred from Belle
Plaine, through Marengo, to North Liberty. Early morning
temperatures ranged from the mid 60s around Freeport, to the mid
70s in southeast Iowa.

&&

.SHORT TERM...(Today and Tonight)
ISSUED AT 314 AM CDT Sat Jun 25 2022

Key messages:

1) Morning storms with heavy rain, then afternoon/evening
redevelopment.
2) Hot and humid today, especially south of Interstate 80.
3) Some potential for a few severe storms this afternoon and
evening, along and east of the Mississippi River

Today: Widespread thunderstorms will continue to push east this
morning, with the highest coverage along and north of Interstate
80. Thus far, the main threat is heavy rain and isolated flash
flooding. Max rainfall amounts of 3+ inches have fallen so far in
parts of Benton, Iowa, and Johnson Counties. Will continue to
watch closely for localized flash flood threat, particularly in
urban areas.

This afternoon, heat index values could approach 100 degrees along
and south of Interstate 80, depending on cloud cover. Cannot rule
out reaching advisory criteria in some places, but will defer to
day shift to re-evaluate.

By late afternoon, scattered storms are expected to fire along a
cold front near the Mississippi River. Latest CAMS favor storm
coverage near and east of the river, coincident with the SPC
marginal risk area. Right now, we're looking at a relatively low
risk of large hail and damaging winds.

.LONG TERM...(Sunday through Friday)
ISSUED AT 314 AM CDT Sat Jun 25 2022

Largely unchanged forecast for the period as a beautiful day Sunday
and Monday are still on track across the area.  After this the flow
turns to a more hot and humid pattern. Wednesday and Thursday
continue to show highs in the 90s ahead of a cold front.  This seems
to be a pattern as of late.  Cold front with milder temps, increase
in heat and humidity, then a front with pop chances. Guidance agrees
on the frontal passage sometime Friday.  This looks to be the next
best chance for pops in the extended.

&&

.AVIATION...(For the 06Z TAFS through 06Z Saturday Night)
ISSUED AT 117 AM CDT Sat Jun 25 2022

An area of thunderstorms will continue to expand across the region
through the early morning hours, before pushing east after 15z.
MVFR vsbys will be common in storms, with brief periods of IFR in
the most intense rain. Afternoon storm redevelopment is expected,
but there are questions on location and timing, with some
indications that this may occur east of the Mississippi River. So
for now will leave afternoon storms out of TAFs.
