URGENT - WINTER WEATHER MESSAGE
National Weather Service Quad Cities IA IL
1154 AM CST Thu Feb 7 2019

...Another Winter Storm with Mixed Precipitation...

.The rain and freezing rain will continue to transition to sleet and
then snow before ending from west to east by mid afternoon through 
sunset. Additional ice accumulations of up to a tenth of an inch 
will be possible east of the Mississippi River. Meanwhile, snow 
accumulation of around inch possible northwest of a Cedar Rapids, 
Iowa to Dubuque, Iowa line. Strong northwest winds gusting 30 to 40 
mph may lead to blowing snow and periods of reduced visibilities 
over portions of northeast Iowa even after the snow has ended. As 
these strong winds develop further southeast there is potential 
for tree damage and power outages where significant ice accumulation
occurred. In addition, much colder air will lead to a freeze up of 
moisture leading to slick surfaces and hazardous travel into this 
evening. The gusty winds and cold temperatures will also lead to 
dangerous wind chills of 15 below to 25 below zero tonight through 
much of Friday morning.

Area Forecast Discussion
National Weather Service Quad Cities IA IL
315 PM CST Wed Feb 6 2019

.SYNOPSIS...
Issued at 313 PM CST Wed Feb 6 2019

Mostly cloudy skies were in place across the region thanks to
moisture and WAA along a warm front stretching from central Oklahoma
to central Indiana. This WAA was also creating enough instability
aloft, allowing for the development of thunderstorms across portions
of east central Iowa this afternoon, which were even producing hail
up to pea size! Temperatures changed little at the surface due to
the cloud cover and light winds, and as of 3 PM ranged from 27 in
Dubuque, to 33 in the Quad Cities.

&&

.SHORT TERM...(This Evening through Thursday)
ISSUED AT 313 PM CST Wed Feb 6 2019

Very challenging forecast shaping up for the short term period with
mixed precipitation moving in this afternoon and tonight.

First wave of precipitation now moving across the region in response
to increasing WAA aloft taking place across southern IA. Sleet,
freezing rain and rain will be possible with the activity as it
moves through, with the potential also existing for hail up to a
half inch in thunderstorms. This wave will move north through this
evening, giving much of the region a quick break through 9-11 PM.

The main forcing arrives around midnight as a deep trough and
embedded vort maxes move into the eastern Great Plains. Surface
low will develop ahead of this trough over central Oklahoma, and
will quickly dash north into the Midwest late tonight. Copious
amount of warm air aloft and moisture to build north ahead of the
surface low thanks to strong 850 mb transport, LLJ and the warm
front, which will set up nearby across central IL. This front and
subsequent warm air aloft will continue to wreak havoc with
precipitation type forecasting heading into Thursday.

Primary precipitation types look to be freezing rain and sleet once
again across eastern IA due to the warm air aloft, and is supported
by global and high-res forecast soundings across the area. Further
east, warming surface temperatures will allow most NW Illinois to
see mix with or change over to all rain tomorrow morning. As the
system moves east and colder air wraps around the surface low,
expecting precipitation to gradually wind down and change to all
snow. Counties along and northwest of Highway 151 will have the
potential to see 1-3 inches of snow by Thursday evening where
colder temperatures will stick around longer.

Now to headlines. After collaboration with surrounding offices, have
gone ahead and upgraded portions of southeast Iowa and northeast
Missouri from a Winter Weather Advisory to an Ice Storm Warning as
QPF amounts across the area have increased. Ice amounts across this
area may approach 0.3 inches through Wednesday evening. Winter
Weather Advisories remain in effect elsewhere where expected ice
amounts will remain model. There is the potential for heavier ice
amounts further northeast along the Mississippi River, but have held
off on potential upgrades due to lower confidence on amounts and
potential for rain to mix in.

.LONG TERM...(Thursday Night through Wednesday)
ISSUED AT 313 PM CST Wed Feb 6 2019

Thursday night...Wrap around light snow and flurries mainly along
and north of Hwy 30 through mid evening with little or no additional
accumulation, but the main story will continue to be the brisk
northwest winds gusting to 35 MPH during the evening, and strong
cold air advection. With ambient temps making it down into the
single digits above and below zero, combined with the winds
widespread wind chills of 15 to 25 below still on track. Wind Chill
advisory criteria looks to be reached from midnight on through at
least 10 AM Friday morning along and northwest of a line from Iowa
City, to Clinton IA, and to Freeport IL. The western Hwy 20 corridor
may even have wind chills pushing 28 below. With the winds, will
maintain some areas of drifting and blowing snow in the northwest Thu
evening in areas that get a few inches of new snowfall.

Friday and Saturday...Harsh wind chills Friday morning, with the
rest of the day a cold blustery one, but wind decreasing late making
for a very cold night into early Sat morning. Some 5 to 10 below
values possible north of I80 where there is some lingering snow
cover, other areas around zero to a few degrees below zero possible.
High temp recovery into the upper teens and 20s Sat afternoon.

Sunday...12z medium range model runs continue to advertise a sfc low
skirting to the south with inverted trof sweeping acrs the area.
Light to moderate snow amounts possible by Sunday evening across
much of the DVN CWA.

Monday through next Wednesday...A low confidence period, but the
longer range guidance continues to suggest a stronger low pressure
wave to roll up somewhere acrs the Midwest, with either significant
amounts of snow or wintry mix possible. The track will be pivotal,
with the 12z GFS bring it up far enough to the northwest that the
southeast half of the CWA sees mainly rain on Tuesday. Strong winds
may wrap in behind the system as well if the sfc low deepens as much
as the ominous 12z ECMWF suggests.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon)
ISSUED AT 1114 AM CST Wed Feb 6 2019

Complicated TAF period with poor flying conditions expected overall.
Persisting low clouds will keep MVFR/IFR conditions in place through
the remainder of the afternoon. Late this afternoon and evening, our
next winter system will arrive and spread precipitation across the
region. Precipitation types will vary by site, with high confidence
KCID/KDBQ will remain cold enough to see all -FZRA. Low confidence
exists for KMLI, where -FZRA initially will change to all -RA as
temperatures climb slightly above freezing this evening. High
confidence KBRL will remain warm enough during the period to see -RA
as temperatures remain above freezing across the area. The potential
also exists for thunder to impact KMLI/KBRL/KCID as several high-res
models show weak instability aloft building across the region.
However, will only mention here due to low confidence on exact

departing system will allow for -SN to mix in with -FZRAPL at

.HYDROLOGY...
Issued at 313 PM CST Wed Feb 6 2019

Area rivers continue to respond to recent snow melt induced run-
off, as well as ice action/jams. Significant rises continue with
minor to moderate flooding ongoing or forecast on many area
tributary rivers, as well as on the Mississippi at Gregory
Landing. But ice jams breaking up have allowed a few sites to drop
off as well over the past 12 to 24 hours. Still, additional ice
action will have to be kept in mind as it may produce sudden
fluctuations from the expected river levels at many sites through
the end of the week. Also, the potential for seasonably high
rainfall across portions of the area tonight and possibly
aggravating ongoing flooding, or creating new flooding situations
will have to be kept in mind.

Emergency management reported a levee had failed on the north side
of the Green River between Colona and Geneseo Illinois due to an
ice jam. Flooding is ongoing mainly on the north side of the Green
River and surrounding the Hennepin Canal. Some roadways in Henry
County in the Colona area are closed due to flooding with
moderate flooding ongoing along the Hennepin Canal State Trail. An
Areal Flood Warning has been issued for this area through this
coming Sunday.

The Rock and Pecatonica River basins: Flood warnings for
moderate flooding continue on the Rock River at Joslin and
Moline. Ongoing ice action combined with the recent snow melt is
having a large impact in holding up river levels, and this should
continue into early next week. Also, bouts of rain tonight and
into Thursday will run-off and contribute to the high water
levels and possibly aggravate ongoing ice jams. A flood warning
continues for the Pecatonica River at Freeport, where the river is
forecast to reach flood stage by Friday evening.

The Maquoketa, Skunk and Wapsipinicon Basins: Recent snow melt
combined with ice action will keep the Wapsi near De Witt
hovering above flood stage through the weekend, unless the ice
jam breaks or gives way. On the Maquoketa River at Maquoketa, the
ice jam has given way and river levels there continue to fall
below the flood stage.  Ice jams continue to force river levels
up on much of the North Skunk and Skunk Rivers as well. At Augusta
where a large ice jam forced water to the major flood category
yesterday, it is falling now but still in moderate flood levels.
Will have to watch these sites as continued ice in the river
channel may cause further fluctuations in the river levels through
Thursday.

Iowa and Cedar River Basins: The Cedar River near Conesville is
cresting below flood stage and thus the flood warning has been
cancelled there. Ice action will cause the Iowa River at Marengo
to fluctuate around the moderate flood stage through tonight,
before falling. The Iowa River at Lone Tree has crested below
moderate flood stage and is falling. The latest forecast for the
Iowa River at Oakville, has the river level rising around the
flood stage by Thursday morning. Most other sites on the Iowa
will experience within bank rises near or above action stages
through the weekend.

Mississippi River: A confirmed ice jam is keeping water levels
high just above the flood stage at Gregory Landing on the lower
Mississippi River. Will keep the river in a flood warning trough
the weekend, with ongoing ice action and incoming flow keeping
levels up at that site. The ice jam there may produce quick river
level fluctuations(rises and falls) of several feet over the next
several days as the ice shifts and adjusts. Elsewhere on the
Mississippi, as ice and run-off from the tributaries move into the
mainstem, more localized ice impacts may continue on other
locations for river level fluctuations.

High water from snow melt and ice will continue to keep the La
Moine River near Colmar IL fluctuating around the flood stage
through tonight. More rainfall tonight may hold up river levels
or produce additional rises from the expected levels through
Thursday night.

This Hazardous Weather Outlook is for portions of north central
Illinois...northwest Illinois...west central Illinois...east
central Iowa...northeast Iowa...southeast Iowa and northeast
Missouri.

.DAY ONE...THIS AFTERNOON AND TONIGHT

Two waves of freezing rain and sleet will impact the area tonight.
One will move northeast through the outlook area late this
afternoon and very early this evening. Road temperatures are near
freezing, and patchy icy roads can be expected, mainly on
untreated surfaces with this early wave of freezing rain. After
the rains move out by 6 PM, several hours of freezing drizzle can
be expected, which will again bring the risk for slick
conditions.

After midnight, a large area of freezing rain, sleet, and even a
few thunderstorms will move up over the entire area. Ice
accumulations over a quarter inch are expected over portions of
southeast Iowa, where a Ice Storm Warning is in effect the day
Thursday. The rest of the outlook area to the east and northeast,
a Winter Weather Advisory is in effect through Thursday where ice
accumulations will be one to two tenth of an inch. Sleet is also
possible over the entire area, with up to a half inch possible,
mainly where thunderstorms occur.

Area rivers are experiencing flooding. Please see the latest
Flood Statements and Flood Warnings for details.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

The winter mess will continue to bring hazardous travel through
Thursday.

Bitterly cold weather with strong winds, and possibly blowing snow
will sweep in Thursday afternoon and night. Winds will gust up to 30 MPH
Thursday afternoon into Friday as colder air moves into the
region. The wind and cold temperatures will create wind chills of
15 to 25 below zero late Thursday night into Friday morning.
Colder than normal temperatures will continue into the weekend.

Another storm system will impact the region Sunday with snow and more
snow is possible Monday and Tuesday. Due to uncertainty in storm
tracks, it is too early to estimate any potential snowfall
amounts.

.SPOTTER INFORMATION STATEMENT...

Spotter reports of ice amounts over one tenth inch will be
appreciated.
