URGENT - WINTER WEATHER MESSAGE
National Weather Service Quad Cities IA IL
315 PM CST Mon Dec 28 2020

...Winter Storm Tuesday Afternoon into Wednesday Morning...

.A strong winter storm will spread moderate to heavy snow and 
mixed precipitation into the area Tuesday afternoon. The heaviest
snow, with a band of 6 to 9 inches is forecast to set up for 
areas along and north of a line from Milledgeville to Iowa City to
Sigourney. Storm totals of 3 to 6 inches are possible immediately
south of this band to include roughly the I-80 corridor, with 
lower amounts across the far southern outlook area. During the 
heaviest period of snow, from late Tuesday afternoon through 
midnight, peak snowfall rates are likely to reach 1 to 1.5 inches 
per hour, especially for locations north of I-80. The time window 
for these heavy snowfall rates will decrease from north to south 
through the forecast area because of the expectation for a rapid 
changeover to sleet and freezing rain in the counties along and 
south of I-80. The sleet may reach as far north as the highway 30 
counties later Tuesday night as temperatures warm aloft. A tenth 
to a quarter inch of ice accumulation from freezing rain is 
possible mostly south of I-80 before precipitation changes to all 
rain late Tuesday night. A thin glazing could extended as far 
north as the highway 30 corridor before the steady precipitation 
comes to an end early Wednesday morning.

328 AM CST Tue Dec 29 2020

...Winter Storm This Afternoon into Wednesday Morning...

.A strong winter storm will spread moderate to heavy snow and
mixed precipitation into the area Tuesday afternoon. The heaviest
snow, with a band of 6 to 10 inches is forecast to set up for 
areas along and north of a line from Sigourney, Iowa to Iowa City
to Clinton, and Milledgeville, Illinois. Storm totals of 3 to 6 
inches are possible immediately south of this band to include 
roughly the I- 80 corridor near the Quad Cities through Sterling,
Illinois. Heavy sleet is also possible within that band near
Interstate 80. To the south, lower amounts of snow and sleet are
forecast, generally under 3 inches. During the heaviest period of
snow, from late afternoon through 10 PM, peak snowfall rates are 
likely to reach 1 to 1.5 inches per hour, especially for locations
north of I-80. The time window for these heavy snowfall rates 
will decrease from south to north through the forecast area 
because of a rapid changeover to sleet and freezing rain in the 
counties along and south of I-80. The sleet may reach as far north
as the highway 30 counties later this evening as temperatures 
warm aloft. A tenth to a quarter inch of ice accumulation from

...Winter Storm This Afternoon into Early Wednesday Morning...

.A strong winter storm will spread moderate to heavy snow and mixed 
precipitation into the area during the early and mid afternoon. The 
heaviest snow, with a band of 6 to 10 inches is forecast to set up 
along and north of a line from Sigourney, Iowa to Iowa City to 
Clinton and Milledgeville, Illinois. Storm totals of 3 to 6 inches 
are forecast immediately south of this band to include roughly the I-

During the heaviest period of snow, from the late afternoon through

freezing rain is possible along and south of the I-80 corridor. A 
thin glazing could extend as far north as highway 30 before the 
steady precipitation comes to an end after midnight. Dangerous

...18z AVIATION UPDATE...

.SYNOPSIS...
Issued at 248 AM CST Mon Dec 28 2020

As of 2 AM, a low pressure area was over the Great Lakes region
while high pressure was building southeastward into Iowa. Locally, a
stratus deck was blanketing much of Iowa, northern Missouri, and
northern Illinois, with a pocket of clear skies from Clinton to
Macomb. Temperatures were in the mainly in the mid and upper 20s,
but Clinton dropped into the teens with the clearing. Dew points
were mainly in the upper teens to mid 20s.

.SHORT TERM...(Today and Tonight)
ISSUED AT 248 AM CST Mon Dec 28 2020

High pressure will build into the area today providing the region
with mostly sunny skies and a west breeze at 10 to 15 MPH.
Temperatures will be near normals, with highs in the upper 20s to
lower 30s. Clouds will spread into the region from the southwest
late tonight, but with light winds and initially mostly clear skies
temperatures will drop into the low teens north to upper teens
south.

.LONG TERM...(Tuesday through Sunday)
ISSUED AT 248 AM CST Mon Dec 28 2020

A significant winter storm is forecast Tuesday into Wednesday.

Changes:

1. A shift southward in all global model data has been noted,
resulting in a longer duration of snow and ice in our area.

2. The southern shift has the axis of heaviest snow falling through
the northern 1/2 of the CWA, rather than clipping our far north.

3. The threat for a period of icing has increased, during the midway
portion of the event, which could bring several tenths of a inch of
ice, especially along an Ottumwa to Sterling Illinois line.

Discussion:

A strong moist warm advection period will commence in our area by
late morning Tuesday, as indicated by all model data. This should be
driven over deep layer, with low levels still quite cold. I feel the
first few hours of precipitation in all areas will be snow, possibly
heavy. The band of moderate to heavy snow will push northeast
through our area Tuesday afternoon and evening, persisting longest
along Des Moines, to Iowa City/Cedar Rapids, to Freeport axis.  As
time goes on Tuesday evening, a warm nose is forecast to transition
snow to sleet and freezing rain, especially in the 9 PM to 8 AM time
frame.  In that period, of precip, it will be dark. Roads will
likely remain cold, and surfaces able to accumulate ice more
efficiently than daytime.  Thus, I feel snow and ice are a balanced
threat for this storm through early Wednesday morning.

Snow amounts of 4 to 8 inches appear likely along and north of a
line from Fairfield to the Quad Cities to Sterling, while just south
of that axis, a band of 2 to 3 inches is expected, where a
transition to ice is expected earlier.  The far south and far east,
a quicker yet transition, with more marginal temperatures should
keep amounts of ice and snow more minimal, less than 2 inches.

In the end, this is probably a headlined event for all areas, with
warning north, and advisory south, but the time frame now has us
thinking a winter storm watch for all but our far south and east.
This should highlight the areas most prone to seeing significant
snow and ice.

While our attention is placed on the Tue-Wed storm, there is yet
another potential winter event forecast for Thursday PM through
Friday AM. The ECMWF remains bullish on forecasting a large
deformation zone event. We will begin highlighting that possible
storm in the coming day,  but with the notable day 2-3 storm, we
will not be able to message that one directly yet.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
ISSUED AT 1121 AM CST Mon Dec 28 2020

Low MVFR stratus will continue to impact BRL/MLI terminals this
afternoon before dissipating/advecting out of the region. Winds
will switch out of the east Tuesday morning along with an increase
in VFR clouds ahead of approaching winter storm to impact the
terminals Tuesday afternoon and evening, just beyond the 18z TAF
period.

Missouri.

.DAY ONE...TODAY AND TONIGHT

No hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

A winter storm watch has been issued for nearly all of eastern
Iowa, and portions of northwest Illinois, from Tuesday Noon,
through Noon Wednesday. This watch has been issued for the
potential for both significant accumulating snow, as well as sleet
and freezing rain.

A winter storm will spread snow over the area Tuesday afternoon.
Snow will become heavy at times through Tuesday night, especially
along and north of a Fairfield Iowa to Quad Cities, to Sterling
Illinois line. At this time, it appears 3 to 8 inches of snow is
likely to fall along and north of that line. South of that line,
snow will change to a mix of snow, sleet, and freezing rain
Tuesday evening and overnight. Travel is expected to become slick
and difficult Tuesday afternoon through Wednesday morning.

Slick travel conditions are possible throughout the entire
outlook area Tuesday afternoon through Wednesday morning.

Another storm system may spread snow over the area Thursday
afternoon through Friday. It is too early to determine the snow
potential for that storm, but it is likely to bring travel impacts
to much of the Midwest.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
