...AVIATION UPDATE...

.UPDATE...
Issued at 859 PM CDT Thu Sep 22 2016

I have issued a flash flood watch for our Highway 20 counties in
northeast Iowa, where storms are already beginning to train and
move over the same locations repeatedly. With PWAT values around 2
inches overnight, these could easily produce rainfall amounts of 2
to 4 inches, possibly more in localized areas. The HRRR suggests
storms should continue to be active overnight, possibly through
mid morning, and that will be how long I carry this watch.

&&

.SYNOPSIS...
Issued at 345 PM CDT Thu Sep 22 2016

Remnants of the larger MCS last night in northern IA/southern MN
which dropped 4 to 10 inches of rain continues to fester in the
form of scattered showers and isolated thunderstorms in the dvn
cwa. This is mainly north of Interstate 80 along a CAPE gradient.
Extensive cloud cover was keeping instability in check in the
north with 3 pm temperatures in the lower to mid 70s. More
sunshine in the far south was allowing for temperatures near 90.

Looking to the west, skies were sunny in western and central IA
where the better low level convergence, stronger deep layer shear,
steeper lapse rates and higher CAPES were located. This is where
additional convection should fire later this afternoon. Haase

&&

.SHORT TERM...(This Evening through Friday)
ISSUED AT 345 PM CDT Thu Sep 22 2016

Forecast focus on thunderstorm chances mainly north.

Tonight: CAM's models indicated thunderstorms to fire across
northern/central IA later this afternoon and evening. These
storms should then push eastward across roughly the northern half
of the dvn cwa this evening and overnight. The ECMWF/GFS is a bit
farther south with the heaviest rain axis compared to the HRRR.
The better coverage of storms should be in eastern IA and northern
IL along and north of Interstate 80 so this is where the highest
pops will be. Some of the storms may produce locally heavy rainfall
of potentially at least an inch or two. Any repeating storms over
the same area may produce several inches of rainfall in a short
time with PWAT's approaching 2 inches. There is still uncertainty
of where exactly the highest rain amounts will fall tonight with
variance in the models. Later shifts can monitor convective trends
and adjust pops if needed. Minimum temperatures should be in the
mid to upper 60s.

Friday: Scattered thunderstorms are possible over most of the cwa
in the morning then the storms should shift northward as an upper
level ridge/building heights shifts into the area. This will push
the warm front northward into Wisconsin as the day progresses.
Much of the afternoon should be dry except we will still carry a
chance pop in the north. Highs should be in the upper 70s along
Highway 20 to the mid to upper 80s elsewhere. This will again be
a warm and humid day at most locations with dewpoints well into
the 60s.  Haase

.LONG TERM...(Friday Night through Thursday)
ISSUED AT 345 PM CDT Thu Sep 22 2016

Friday night and Saturday, an upper ridge will traverse the forecast
area with mainly dry and unseasonably warm conditions. Saturday
night and Sunday, active weather will return with sharp
southwesterly flow aloft and a slow moving cold front oriented
parallel to the upper flow. Precipitable water values are expected
to rise close to 2 inches once again. This scenario will be
favorable for additional heavy rain, especially across eastern Iowa,
which will be crucial regarding river flooding next week. The
potential for severe storms is minimal due to a number of factors,
including timing and relatively weak deep layer shear.  RPK

Sunday night...Latest trends(more progressive) on the various medium
range models suggest a post-frontal shower regime laying out mainly
along and east of the MS River Valley, which would ideally be away
from the swollen IA tributary rivers. Both the 12z NAM and ECMWF
mainly have light rainfall amounts of 0.15 inches or less in these
areas, while the 12z GFS is more bullish with post-frontal moisture
stream making for 0.25 to over a half inch of additional rainfall
from the MS RVR on eastward. For now will take a QPF blend and
migrate POPs more toward the east.

Monday and Tuesday...Large model descrepancies start popping up with
the major medium range players the 12z GFS and ECMWF early next
week. The GFS blocks a nearly stacked cyclone acrs far northern MN,
while the new ECMWF is further north and more progressive with the
upper trof migrating the main axis toward James Bay by Monday
evening. Both models are basically dry for Monday for different
reasons, the GFS with the CWA under in-whirling dry slot into the MN
cyclone center, while the Euro starts exiting out broad cyclonic flow
in favor of upstream ridging. Highs mainly in the 60s on Mon.
Model differences really apparent on Tue with The GFS wrapping
around instability showers acrs the northern half of the CWA Tue
afternoon, while the 12z ECMWF maintains dry, in-building ridge
regime and near normal temps in the upper 60s to lower 70s. For now
will have to maintain low/slight CHC POPs with the descrepancies but
at least that is a drier trend. With a cloud clear out, Tue night
lows will be down in the 40s for most of the area.

Wednesday and Thursday...Longer range trends are for an Omega Block
type pattern to set up shop acrs the mid CONUS somewhere, which
would translate to welcome mainly dry weather and seasonable temps
for the mid to late week period. But again, the latest run medium
range models especially the GFS/ECMWF, vary in placement of their
mean axis. The GFS keeps a trapped/blocked cut-off upper low far
enough to the west acrs the western GRT LKS to spiral more showers
back acrs the area Tue night into Wed, while the Euro progresses the
Omega Block axis eastward to the MS RVR Valley basin by late Wed
night and continues a basically dry regime into day 7 of the
forecast. Again with the descrepancies, will keep low POPs for
showers mainly acrs the northeastern to eastern half of the CWA Tue
night and Wed, then dry for Thu. But if additional model runs
continue to progress with the incoming pattern regime, see the drier
ECMWF solutions winning out for mid next week. Temps may generally
be in the 60s to around 70 for highs, and lows in the 40s. Clouds
will make for cooler highs and milder lows in spots if cyclone wrap
around stratocu maintains more or hangs on with higher coverage than
currently expected.    ..12..

.AVIATION...(For the 06Z TAFS through 06Z Friday Night)
ISSUED AT 1146 PM CDT Thu Sep 22 2016

Thunderstorms will continue to move over the Highway 20 corridor
in northeast Iowa through the night. The DBQ TAF is primaryimpacted
by this, and flash flooding will affect many areas in that region.
Otherwise, VFR conditions should persist south of these
thunderstorms, with only a few spotty showers found. Some early
morning light MVFR fog is possible in southeast Iowa toward
sunrise, before another VFR day spreads over all of the area south
of Highway 20. The tremendous rainfall event overnight in the
north may keep some MVFR clouds around through late morning there
along with some shower activity. ERVIN

.HYDROLOGY...
Issued at 345 PM CDT Thu Sep 22 2016

Overview: Repeated rounds of very heavy rain have occurred over
northern Iowa, southeastern Minnesota, and western Wisconsin over
the past three days. A widespread 3 to 5 inches of rain has fallen
with isolated amounts of 6 to 9 inches. Additional heavy rainfall
is possible tonight and again Saturday night in the same general
area.

These extreme rainfall amounts will result in significant river
level rises downstream into eastern Iowa, including the
Mississippi River, into next week.

The majority of local river sites are now under either a flood
warning or flood watch as significant rises are forecast to begin
this weekend or early next week.

Warnings:

On the Cedar River, Iowa River, Wapsipinicon River (De Witt 4S),
and Mississippi River (sites Dubuque LD11 and Dubuque)

Confidence...Moderate on river level forecasts. Uncertainty arises
with respect to forecast crests, not on whether river levels will
exceed flood stage. How high rivers rise above moderate or major
flood stage is dependent on the downstream propagation of upstream
runoff. As new data is gathered over the coming days, forecast
confidence will likely increase.

Watches:

on the Mississippi River (all sites except Dubuque LD11 and
Dubuque) and Wapsipinicon River (Independence and Anamosa).

Confidence...Low to Moderate on river level forecasts because
river levels will depend on the amount of runoff that is routed
downstream through several tributary rivers. As new data is gathered
over the coming days, forecast confidence will likely increase.
