level flow and moisture trapped near the surface and expect the
low level cloudiness to remain overnight. Temperatures will only
drop 5 to 10 degrees given the extensive cloudiness and lack of
overall near surface advection.

Monday PM - Tuesday PM Winter Weather Potential + Strong Wind
Potential...

Winter Weather...
21z GOES-R Water vapor imagery picking up on a very well-defined
closed upper low crossing into northern California via Oregon.
This low is slated to continue propagating southeastward towards
the Rockies- making it there by 12z to 18z Monday- while
continuing to push eastward through the upper Midwest. By 00z Tue,
this system should be near the Great Lakes region. The
temperatures will be challenging again. Similar to the previous
winter weather event, models are initializing poorly with 18z Sun
temperatures from source region (Kansas)... The GFS and especially
ECMWF, in particular, have initialized anywhere between 5 and 10
degrees too warm with these temperatures. The NAM and the Canadian
models have initialized the coolest and the best, so have leaned
towards them for hourly sfc temps from 12z Mon-00z Wed. Lastly,
upper jet dynamics are supportive as- similar to the previous
event- Iowa will be fairly coupled with the left exit region of an
upper jet over our south, and the right entrance region of a jet
to our north/northwest.

By 18z Mon, the sfc reflection low should be coming off the Rockies
in western Kansas. As this low comes off the Rockies, phased with it
will be a "warm" advection wing that extends w-e all the way into
the Ohio Valley region. From 12z-18z Mon, am expecting a
subsequent band of generally thermodynamically-driven precip to
form in southern Iowa and push northward throughout the daytime...
making it to the Des Moines metro by around noonish. With the
better moisture not arriving until the 18z Mon-00z Tue period, am
expecting more light freezing drizzle than freezing rain for
Monday morning through the early afternoon hours.

After 21z Mon, the better moisture arrives in Iowa, from south to
north, which will help saturate low-levels of the atmos and increase
precip intensity. Temperatures begin to cool as the night
progresses, helping change precip from a fzdz/fzra mix to pure snow.
Overall, forecast soundings of the various models support continued
snow after the fzra/fzdz --> snow transition occurs. So have knocked
down ice accumulations from inherited forecast back to where they
were previously yesterday afternoon... namely, in the Tr. to 0.05"
inch of ice accumulation range.

Major heads up with QPF in that the 12z Sun ECMWF and 18z Sun NAM
both came in with much higher QPF amounts across the area... with a
large swath of 1" to 1.5" QPF totals... practically double what we
have currently have forecast. Worth noting that these hypothetical
double QPF amounts would not 1:1 double the snow amounts due to the
supercooled water droplets and modification of snow growth
processes that would subsequently occur. As of now, it appears the
highest QPF totals will be during the 00z-06z Tue timeframe. Have
a Winter Storm Watch out now, with anticipation of it being
upgraded to a Winter Storm Warning either this evening or tonight,
especially along and north of I-80, including the Des Moines
metro. From 12z-18z Tue, there will likely be lingering snow &
flurries east of I-35... and by 18z-21z, effectively all snow
should be east of the DMX CWA.

Strong Winds...
In the past 24 hours, the track of the sfc low has shifted
southward considerably... In the 12z Sat model package, the
highest 3-hr pressure rises on the backside of this system were
located over northern Missouri. In the 12z Sun model package,
these highest 3-hr pressure rises are into southern
Missouri/northern Arkansas. While it will still be windy, this
will serve to keep the strongest winds to the south. However,
forecast soundings still show winds in the 35 to 40 kt range
through the transport/mixed layer, which will keep it windy.

Impacts...
Monday 7AM - 12PM: Light freezing drizzle may impact southern
Iowa during the late morning hours. Overall impacts should be
minimal during this time.

Monday 1PM - 6PM:  The afternoon/evening commute will likely be
impacted by snow across most of the state, especially along and
north of I-80. Travel conditions, quite frankly, could become a
mess. Snowfall amounts during this commute timeframe are expected to
be near Tr. to 2 inches, with the highest amounts in west-central to
southwestern Iowa. Poor visibility may be the worst driver of
impacts, as visibility may be down to 1/2 mile or less at times
during periods of more heavy snow/heavy fzra/sleet. Untreated, less-
traveled roadways may become snow-covered and slippery. If you plan
on traveling Monday afternoon/evening, certainly keep an eye on the
forecast and be prepared for increased travel times and reduced
travel speeds. PLEASE USE EXTRA CAUTION IF TRAVELING DURING THIS
TIME!

Monday 7PM - 6AM:  This is when most snow will fall across central
to northern Iowa. Along and north of I-80, snowfall amounts of 4 to
8 inches is expected, with the highest totals in northern Iowa.
South of I-80, 1 to 4 inches of snow is expected. Many roadways will
become snow-covered and slippery. If you plan on traveling during
this timeframe, certainly keep an eye on the forecast and be
prepared for hazardous travel conditions- leading to increased
travel times and reduced travel speeds over snow-covered and
slippery roads. PLEASE USE EXTRA CAUTION IF TRAVELING DURING THIS
TIME!

Tuesday 7AM - 12PM:  The winds will be very strong during this time
period, blowing from the NW @ 15-25 mph, with gusts to 35 mph. This
will likely lead to blowing and drifting snow... especially where
the highest snowfall totals occur- likely in northern Iowa.
Visibility could be incredibly poor at times, especially near
open fields where blowing snow will be more unrestricted. If you
plan on traveling Tuesday morning, certainly keep an eye on the
forecast and be prepared for increased travel times and reduced
travel speeds. Also prepare for areas of greatly reduced
visibility due to blowing and drifting snow.

----------------------------------------------------------------

Thursday-Saturday Winter Weather Potential...

Long range models suggesting yet another winter storms impacting the
Midwest sometime during this timeframe. As anticipated in
yesterday afternoon's AFD, models are beginning to tighten on a
solution and track... that actually looks somewhat similar to this
current system... only potentially stronger, with a sfc low
possibly dropping to 985mb and a 1030mb sfc high over the
backside. This would intuitively suggest a very strong wind
potential with wintry precip.

Tracing this system back to its source region takes us all the way
to the Gulf of Alaska. By 00z Mon... if this system holds... should
be much more well-defined and off the British Columbia coastline. So
am ultimately expecting an even bigger increase in model handling of
this system with the 00z Mon models... until then not worth getting
into details too much other than to say that this is something that
absolutely bears monitoring.

IFR conditions will continue through the TAF period at all sites
as ceilings around and below 1000 ft dominate and visibilities
drop during the latter half of the period as snow enters the
sites. Lingering patchy dense fog will continue to pester KOTM
overnight before subsiding as winds increase towards sunrise.
