Area Forecast Discussion
National Weather Service Quad Cities IA IL
655 PM CST Sat Feb 23 2019

.UPDATE...
Issued at 625 PM CST Sat Feb 23 2019

High moisture pooling in the warm sector ahead of the surface low
has been causing dense fog to develop. The most extensive coverage
of the dense fog currently is over northeast Missouri into west
central Illinois. Expecting the fog to lift northward and stay
just ahead of the surface low as it lifts to through Iowa
overnight. The dense fog advisory will be in place until 10Z,
however it is likely that the southern and western areas will see
improvement prior to that time.

&&

.SYNOPSIS...
Issued at 140 PM CST Sat Feb 23 2019

Record moisture transport into our are overnight resulted in a
widespread rainfall event of 0.75 to 1.25. That rain has resulted
in extensive field flooding, and rises on area creeks and rivers.
The intensifying low is now located in central Kansas, and is set
to move up over the CWA this evening. This next round will have
even more moisture than last night, which is mind boggling, but
will also be much more progressive in nature, thus rain amounts
will likely be lesser than last night. From a climate standpoint,
this will fall in the same calendar day, resulting in many
locations seeing record precipitation for the day, and possibly
flash flooding.

&&

.SHORT TERM...(This Evening through Sunday)
ISSUED AT 140 PM CST Sat Feb 23 2019

Incredibly, though rains will be locally heavy, most of this
evening will not see high winds, but rather fog as a potential
hazard, as the low moves overhead. Our forecast is already very
complicated and do not plan on issuing a dense fog advisory, but
will focus on shorter term SPS for the fog. The rain event is
already underway, which may locally improve conditions at times,
but in the end, the main story for the evening remains focus on
flood threats, followed by wind overnight into Sunday. I have
increased confidence that some snow falls after midnight in the
northwest, which should be falling on freshly iced up wet fields.
Any snow falling on the frozen landscape will be capable of
blowing in the very strong winds. Winds are forecast to be
sustained 25 to 30, with gusts around 50 to 55 mph. Bufkit
sounding show around 40 to 45 kts at the top of the mixed layer
tomorrow morning when we see the strongest surge of winds. That
paints this as a high end advisory, one where we'll need to watch
for a possible upgrade to high wind warning.

Winds remain strong through 00z Sunday, and current products run
through 03Z, which still seems a good fit. The Winter weather
advisory will match this, but if the blowing snow threat
diminishes, or doesn't verify, we can always revert back to a wind
based headline.

Temperatures will continue to slowly rise this evening, as will
dewpoints. The low pressure should pass over DBQ between 03 and
06Z, and right after that, winds from west to east will greatly
increase. Temperatures will quickly crash to the lower 30s, and by
early morning, mid 20s west, to mid 30s east. By sunrise, falling
readings to upper teens west to upper 20s east will also serve as
the high temperature for Sunday, when steady or slightly falling
temperatures are expected in the strong winds. Wind chills, all
day will remain in the -5 to +5 range.

.LONG TERM...(Sunday Night through Saturday)
ISSUED AT 140 PM CST Sat Feb 23 2019

Sunday night: Winds will be diminishing but temperatures will be
much colder, with lows in the single digits, maybe just below zero
in our far nw counties. Wind chills will be dipping to 10 below to
20 below along and north of Interstate 80, but a wind chill advisory
looks marginal at this time.

Monday through Thursday: Well below normal temperatures for much of
this upcoming week, with highs in the teens and 20s common. Lows
will drop into the single digits and teens. Low confidence at this
time concerning timing/intensity/track of upper level disturbances
in the nw flow. There doesn't appear to be any significant storm
system's to impact the dvn cwa, but can't rule out some minor
accumulations if an upper level disturbance can manage to come
across the area. Models suggest the bulk of the pcpn to stay north
or south of the cwa.

Friday into next weekend: The GFS remains the more aggressive model
depicting a strong upper level trough coming across the area, with
the potential for significant snow. However, the ECMWF does hint at
some snowfall developing in the cwa but then quickly moves off our
east as the surface low deepens well to our east. There is certainly
a phasing issue being this is a week away so the best approach is to
stay tuned. Following this system much colder arctic air returns
with 850 mb temperatures dipping to -20c to -25c into our area.

Haase

.AVIATION...(For the 00Z TAFS through 00Z Sunday Evening)
ISSUED AT 625 PM CST Sat Feb 23 2019

Messy weather for aviation concerns tonight. A strong storm system
is currently centered over eastern Kansas and will lift northeast
tonight. Overnight, dense fog will be observed at the terminals
along with rain and generally LIFR or IFR ceilings, while
scattered thunderstorms will be observed. Winds will follow later
tonight as the system moves through, first picking up from the
southwest and then to the northwest on the backside of the system.
The northwest winds will be quite strong through the day Sunday,
with sustained winds of 25 to 30kts, with gusts up to 50 kts at
times. Winds will begin to diminish by late afternoon Sunday, but
will still be high through the 00Z time. Visibilities and ceilings
also will be improving through the day on Sunday. There could be
periods of light snow, mainly through Sunday morning. In these
snow showers, visibilities will drop due to the strong winds.

&&

.HYDROLOGY...
Issued at 1114 AM CST Sat Feb 23 2019

Confidence has increased to upgrade the following locations from a
Flood Watch to a Flood Warning due to recent rainfall:
Wapsipinicon River near De Witt, English River at Kalona, and the
Skunk River at Augusta, Rock River near Joslin, and the Rock
River at Moline. 24-hr rainfall amounts between three quarters of
an inch to one and a quarter inch has fallen across much of
southeast Iowa and portions of northwest Illinois. Additional
rainfall is forecast Saturday afternoon between a half inch to
three quarters of an inch, and when combined with snowmelt and
runoff, will result in forecast rises on rivers.

With river levels already running higher than normal, flooding is
again possible through the weekend due to runoff or break up ice
jams. Much of the water in the soil will freeze Sunday afternoon
and evening which will slow the runoff going into rivers. This
may impact rises on rivers and later river forecasts.

A Flood Warning has been issued for the Mississippi River at Gregory
Landing due to an ice jam downstream and recent rainfall. If the
ice jam were to break free as result of increased flow, the stages
would likely drop despite the rising flow on the river to a lower
crest than what is currently forecast.

Moderate flood stage is forecast for the Wapsipinicon River near
De Witt, Rock River near Joslin, and the Rock River at Moline.

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...TODAY AND TONIGHT

A Winter Weather Advisory remains in effect for areas along and
north of Highway 30 through 10 AM for freezing rain and some
sleet. Ice accumulations up to around two tenths of an inch are
expected.

A Wind Advisory is in effect for the entire area from late
tonight after Midnight, through Sunday evening.

A Flash Flood Watch has been issued for the entire area today
through this evening.

Rounds of moderate to locally heavy rain will move across the area
today through this evening. By this evening, much of the area may
have received rainfall amounts generally of a half inch, up to
two inches. This kind of rainfall combined with some snow melt
will produce the threat for flash flooding and general flooding.
Otherwise ponding of water on roads and drainage ditches is likely.
Urban and small stream flooding may also occur as the day
progresses.

Isolated to scattered thunderstorms are possible from roughly 2
PM to 8 PM. There is a marginal risk for severe storms this
afternoon across far southeastern Iowa into west central Illinois.
Hail and damaging winds would be the primary threats from any
strong to severe storm that may develop. Any storm will also be
able to produce locally heavy downpours and add to the flash flood
potential.

Saturday night, the rain is expected to change to snow from west
to east before ending. Snowfall amounts of 1 to 3 inches will be
possible by Sunday morning mainly northwest of a Cedar Rapids to
Manchester Iowa line. Areas to the east and south of those areas,
down to Interstate 80 will get less than an inch of snow.

Very strong west to northwest winds will develop late tonight
through Sunday. Sustained winds of 25 to 35 mph are expected with
gusts up to 50 mph. Higher gusts over 55 MPH may occur during a
couple of hours either side of daybreak Sunday morning. The high
winds may cause blowing and drifting snow in the areas that get a
few inches. Also, the strong winds combined with still falling
snow will produce significantly reduced visibility or even near
blizzard conditions in rural areas.

Run-off from all the rain, as well as snow melt may lead to
considerable rises and possible flooding along area rivers.
Breakup ice jams will also be a concern.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

Very strong winds of 25 to 30 MPH and gusts to 50 MPH will
continue Sunday through Sunday evening. Higher gusts will be
possible in the morning. A Wind Advisory is in effect through
Sunday evening.

Wind chills may approach 20 below zero by Monday morning along
the Highway 20 corridor.

.SPOTTER INFORMATION STATEMENT...

There is a low chance that spotter activation will be needed this
afternoon. Reports of significant ice accumulations or flooding will
be appreciated today.
