NWS Des Moines, IA wrote its last area forecast discussion before this river flood warning went out at Apr 26, 6:56 PM CDT, 1 hour 16 minutes earlier.

...Updated for 00z Aviation Discussion...

.SHORT TERM.../Tonight through Saturday Night/
Issued at 405 PM CDT Fri Apr 26 2019

Active Weather Through Saturday Night

Short-wave trough will be kicking off the Rockies with surface Lee
Cyclogenesis taking place. This storm system will be moving rather
quickly across central/northern Plains into the Upper Midwest.
Biggest change in today's 12z runs have been a southward shift in
both the GFS and ECMWF, the NAM track did not change all too much.
From a synoptic perspective, this system is looking to be in rather
good health for strengthening with plenty of warm-moist air to
provide fuel for diabatic processes to allow the surface low to
deepen rather quickly. Although the mid-level trough does not dig
far south, the PV anomaly associated with it is rather impressive.
Large scale lift will not be hard to come by with this system, as by
early Saturday morning most of Iowa will be within the left-exit
region of 100 knot jet streak at 300mb. Along the warm front, all
models are in good agreement that isentropic ascent will be rather
strong. In addition, there is no shortage of strong frontogenetical
forcing along the temperature gradients with this system. With that
being said, precipitation will be very widespread and abundant
across the entire forecast area, with the heaviest axis of QPF
across northern and northeastern Iowa. With respect to snow, this is
where the forecast gets tricky. Temperatures will largely determine
the actual snow amounts and snow accumulation that occurs. GFS and
ECMWF came in with surface temperatures closer to 40F. The NAM was
the cooler model from the 12z runs today. For temperatures on
Saturday, have elected to use NAM temperatures and bump them down a
few degrees, given strong dynamic cooling likely. If the
temperatures are able to cool during the afternoon, then the heavy
accumulating snow is likely. Another limiting factor to snowfall
could potentially be where the best lifting occurs. As already
established, there is no shortage of lift. However, examining model
cross section analysis does reveal that the bulk of lift may occur
below the DGZ. Model soundings also are not showing the best DGZs
from the 12z runs, which could be another concern. So even despite
the strong lift, if this does not occur in the DGZ this could
certainly limit snowfall amounts across the north. Thus with this
low confidence and multiple factors that could reduce snowfall, have
opted to stick mainly with a Winter Weather Advisory instead of
Warning for the northern counties, with the exception of Worth
County which has the best potential to see 6-7 inches of snow within
a 12 hour period. The other story with this system will be the winds
across most of the state. In the areas with heavy snowfall, wind
gusts will be up to about 30 miles per hour, which will present
impacts to visibility. However, in southwestern Iowa where the
precip will be mostly rain, wind gusts could reach up to 40-45 MPH.
This may push Wind Advisory criteria, but for now have held off. A
Special Weather Statement will likely be needed for southwest Iowa
tomorrow afternoon for gusty winds.

For Sunday, high pressure will come in and clear skies just as quick
as this storm system came in. Temperatures will be cooler than
normal for this time of year. With heavy rainfall from Saturday,
flooding may be an issue along some rivers and streams across the
forecast area.

.LONG TERM.../Sunday Through Friday/ Issued at 405 PM CDT Fri Apr
26 2019

Active pattern stays the course through the long term period,
beginning with another shortwave trough quickly passing through
the northern Plains Sunday. Upper level QG forcing phases with low
level thermal advection to generate widespread rain showers by
Sunday evening, continuing into the overnight hours before
tapering off early Monday. Precip trends remain on track from
previous forecast as models wavered little with their latest runs.
QPF amounts look to be on the lighter side for most of the
forecast area, but some in southern Iowa may see 0.50"-1" where
elevated instability could support some convective activity.

Early next week the synoptic pattern transitions to a southwesterly
flow regime over the western two-thirds of the CONUS. Several
shortwaves propagating through the mean flow look to deliver
multiple periods of showers and storms to the state. The first such
wave ejects out of the Four Corners on Tuesday/Wednesday and
deamplifies as it crosses the central Plains. Heaviest precipitation
and convection likely remains along and south of a stationary front
draped across OK through MO. Isentropic ascent north of the frontal
boundary should generate rainfall over the cwa, highest chances
residing across the south. Limited instability north of the front
will suppress most potential for severe weather, but can't rule
out some rumbles of thunder in our area. Significant model
difference arise past Wendesday which lends to high uncertainty
with the forecast. Low chances PoPs remain scattered through the
Day 5-7 periods, but is more an artifact of the blends. PoPs
should become more focused as models begin to hone in on a common
solution.

&&

.AVIATION.../For the 00Z TAFS through 00Z Saturday evening/
Issued at 657 PM CDT Fri Apr 26 2019

VFR conditions will deteriorate into MVFR as low pressure swings
through the region bringing rain showers to the area. Colder air
will cause the rain to mix with snow at ALO and change to snow at
MCW during Saturday and this will likely bring at least IFR
conditions. Strong, gusty winds will also accompany this storm
through much of the day before decreasing after 00z Sunday.
Restrictions will improve into VFR late in the afternoon over
northern and western Iowa.
