...Snow, Freezing Rain, and Wind Friday into Saturday...

...Periods of Moderate to Heavy Snow Will Transition to Mixed 
Precipitation This Afternoon Followed by Gusty Winds Creating 
Blizzard to Near-Blizzard Conditions Over Portions of Iowa on 
Saturday...

.Snow continues to move northeastward through central Iowa late this 
morning. While the snow may start light, the rate will increase with 
periods of moderate to heavy snow, which will cause the visibility 
to drop under a half a mile at times. Winds from the southeast 
gusting between 30 and 40 mph will also aid in lowered visibility. 
Snow reports so far range from between 1 and 3 inches over
southeast Iowa with additional snow accumulations expected across
the state.

Through this afternoon, snow rates will decrease with a transition 
to freezing drizzle with minor ice accumulations expected. Then, 
strong winds from the northwest gusting over 45 mph will develop 
early Saturday along with falling temperatures, which should 
result in a flash freeze on roadways. The gusty winds will also 
create widespread blowing snow with visibility under one-quarter 
of a mile at times over parts of northern Iowa.

with blizzard conditions still occurring across portions of
northern Iowa in rural areas. Winds will begin to diminish some

What forecasters said that day

The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Des Moines, IA wrote its last area forecast discussion before this winter storm warning went out at Jan 16, 12:17 PM CST, 1 hour 47 minutes earlier.

Area forecast discussion, Jan 16, 12:17 PM CST, 1 hour 47 minutes before
Area Forecast Discussion
National Weather Service Des Moines IA
1217 PM CST Thu Jan 16 2020

.UPDATE...
Issued at 736 AM CST Thu Jan 16 2020

Update...

Though the Wind Chill Advisory will expire at 9 am, wind chills
will likely remain near to below criteria through noon this
morning.

Am becoming increasingly concerned with hazardous impact potential
for late Friday/early Saturday as potent cold air gradient +
strong winds punches southeastward across Iowa. The impacts could
be like that of a snow- squall warning... Temperatures may fall
around 20 degrees in less than 3 hours, accompanied by the
leading surge of 40 kt wind gusts. This may ultimately lead to
rapid freezing on surfaces... especially untreated surfaces... and
potentially very hazardous travel through Saturday morning. If
snow were to concurrently fall, this would reduce visibility on
top of the above impacts.

Also, wanted to increase mention of potential issues to power lines
and tree branches... If this were a "stand-alone" event with just
one-tenth of an inch, the concurrent strong winds would notably
amplify impacts. With snow ahead of this system, central to southern
Iowa may have higher-impact potential if the snow falls as more
wet/heavy snow.

Increasing confidence in high winds for Saturday. Cannot completely
rule out High Wind Warning criteria being neared across northern
Iowa. The strong northwesterly winds alone would create hazardous
travel conditions... but adding in the potential for icing/blowing
snow may amplify hazardous travel through Saturday afternoon and
evening. Will monitor this closely over the next few forecast
updates.

.DISCUSSION.../Today through Wednesday/
Issued at 441 AM CST Thu Jan 16 2020

...Multiple Hazards Possible Over the Next Few Days...

Key Points:

 1.) Multiple precipitation types likely across our area Friday
through Saturday morning...

 2.) Strong, hazard-level winds at times will play a major role
in contributing to worsening impacts...

 3.) Potentially hazard-level wind chills are forecast for Sunday
and Monday mornings...

Discussion:

1.) Multiple precipitation types likely...

 What:  Snow/Blowing Snow --> Freezing Rain/Ice --> Blowing Snow

 Where: Our entire forecast area

 When: Snow should arrive in SW Iowa shortly by around 4 to 6 am,
spreading northeastward through the morning hours... likely
arriving near the Des Moines metro between 6 to 8 am... and the
Waterloo area between 8 to 10 am.

Snow will likely last most of Friday morning and early afternoon.
Then snow will transition to freezing rain/ice in SW Iowa by mid
afternoon, the Des Moines metro area near the evening commute, and
then the Waterloo area later in the evening. The periods of freezing
rain/ice should last until around sunrise, when it will transition
to light snow and blowing snow. New snow accumulations should be
around 1 inch or less on Saturday.

On a side note, would recommend shoveling before bedtime Friday
evening... with freezing rain/icing appearing plausible overnight,
this would make any fallen snow more difficult to remove.

2.) Strong winds will play a major role in worsening impacts...

 What/Where: Very high confidence in strong winds Friday,
followed by even stronger winds on Saturday. Winds on Friday
roughly along and north of Highway 20 should be SE @ 20 to 30 mph,
with gusts nearing 45 mph. Winds south of Highway 20 will be
around 15 to 25 mph, with gusts nearing 35 mph.

On Saturday, winds across much of our area will likely be in the 25
to 35 mph range, with gusts over 45 mph. The strongest winds will be
in northern Iowa.

 Impacts: During periods of snow Friday afternoon, the strong
winds may reduce visibility to less than 1/4 to 1/2 mile at times
in northern Iowa... and less than 1/2 mile at times in central to
southern Iowa. Further, the strong winds will likely lead to
blowing and drifting of snow back onto roadways... especially in
northern Iowa during Friday.

For Saturday, the strong winds will lead to travel difficulties...
especially for high-profile vehicles, and especially for those
traveling on N-S routes such as Interstate 35. Further, the
strong winds and cold air surging southward may lead to "wheel-
track glazing/black ice" conditions, where the accumulated
snow/ice may re- freeze/freeze on surfaces (especially untreated
ones), potentially leading to icy surfaces and roadways.

3.)  Very cold air may lead to hazard-level wind chill values Sunday
and Monday mornings...

Confidence is very high in cold air surging across Iowa Saturday
through Monday. In fact, temperatures will likely begin to fall
after sunrise Saturday morning, bottoming out Sunday morning near 0
to minus 5 or so degrees across much of Iowa. Factoring in the wind
speeds, wind chill values of -20 degrees may make it as far south as
Interstate 80, with far northern Iowa potentially nearing wind chill
values of near -30 degrees.

For Monday morning, winds should be closer to 10 mph or so, but
actual air temperatures will likely be in the -5 to -10 degree
range... producing wind chill values of -15 to -25 degrees across
most of Iowa. Frostbite to exposed skin can occur within 30 minutes
with wind chills in this range.

Temperatures on Tuesday morning will likely be near to slightly
below zero once again, with wind chill values in the -10 to -15
degree range. In short, temperatures for much of Iowa may not be
above freezing from Saturday morning until the end of next week.

Scientific discussion...

Friday's snow ratios with this event will absolutely be worth
watching. With notably different temperatures profiles from southern
to northern Iowa, snow ratios along and south of I-80 may be closer
to the 5-7:1 range, whereas snow in northern Iowa may be closer to
the 12-15:1 range. Should this play out, the impacts would be
notably different... especially given the strong winds in northern
Iowa. Prior to the transition to freezing precip, northern Iowa may
contend with notably more blowing snow than central/southern Iowa.

Looking at forecast soundings, there appears to be strong saturation
in the -2C to -5C range... which would support crystal habits of
dendrites. In central Iowa, this would be big, wet flakes. In
northern Iowa, the potential large flakes would amplify vsby
reductions. Surface temperatures will be interesting... with fresh
snow, have nudged down temperatures... keeping wind chill values
lowered.

For winds have not seen this favorable of a strong wind setup as is
shaping for Saturday in quite some time. Sfc pressure gradient of
3mb/50km met with a huge swath of +10 mb/3hr pressure rises behind
this system that covers much of northern through central Iowa. With
strong CAA, it should not be difficult to transport mixed layer
winds of 40 to 50 kts to the sfc. If not for potential wintry
impacts, would likely have a wind advisory out. Will see how the
winter weather plays out... but for now, am thinking handling with a
Winter Weather Advisory is the correct path to take... given the
icing potential.

The long-term generally looks quiet. Sunday night into Monday
morning, the 00z operational GFS is trying to kick a very compact,
fast-moving shortwave from NW to SE across Iowa. At this point, the
GFS is an outlier in this solution, so do not have precip mentioned
during this timeframe... but certainly bears watching as Monday
could be a travel day for many. There may be another winter system
for next weekend to contend with... also bears watching.

.AVIATION.../For the 18Z TAFS through 18Z Friday afternoon/
Issued at 1213 PM CST Thu Jan 16 2020

VFR conditions with diminishing wind through 10Z. After 10Z
clouds start to roll back in ahead of a major winter storm.
Impacts to western TAF's will occur after 12Z with impacts to
eastern TAF's closer to the end of the TAF forecast period. Expect
quick deterioration to at least MVFR conditions with increasing
wind and icing possible.
