Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
210 PM CDT Tue Apr 4 2017

.UPDATE...1030 AM CDT...

No big changes for the morning update. Drizzle will ease across
the area in the coming hour in wake of departing low pressure.
There could be some brief breaks in the clouds, but there are
some additional clouds rolling south from Wisconsin ahead of an
afternoon wind shift which will even bring some cooling to lake
areas.

Expect just cloudier but precip free conditions until
precipitation chances ramp back up considerably later tonight into
Wednesday.

KMD

&&

.SHORT TERM...
340 AM CDT

Through Tonight...

A somewhat quiet short term compared to midweek. The 992mb low
pressure across lower Michigan is on its way east, with
wraparound of its broader upper low continuing patchy light
rain/drizzle across the forecast area. Should see some of this
continue to after daybreak along/north of I-80 with a quick fade
in this by mid-late morning as the column begins to dry.
Unfortunately it will not dry enough to void our clouds, as any
afternoon breaks in low cloud cover will quickly be blanketed by
incoming high clouds. Northwest winds and the anticipated clouds
should limit much of a temperature rebound, with only about a 10
degree climb forecast. As the pressure gradient weakens by mid-
afternoon, winds along the lakefront will turn onshore, bringing a
drop likely to the lower-mid 40s.

The next system in this wave train will be moving east across the
central/southern Plains this evening, with a 50 kt low-level jet
developing ahead of it within an area of pronounced upper/mid-
level height falls. Model guidance is in better agreement with
robust 600-850mb warm advection expanding into north central
and possibly northeast Illinois overnight within very favorable
coupled upper jet support. Mid-level frontogenesis in the region
along with indications of convective symmetric instability (CSI)
should produce an area of moderate precipitation expanding east-
northeast into the western forecast area. The column will
initially be warm enough to support rain, but there could be some
snow mixing in across north central Illinois prior to daybreak if
forcing is robust enough for diabatic cooling. Higher potential
arrives during the morning, as noted below.

MTF

&&

.LONG TERM...
340 AM CDT

Wednesday through Monday...

A very active Wednesday-Thursday with a multi-faceted system with
potential impacts of a late season burst of wet snow, moderate to
heavy rain, strong winds, and lakeshore flooding. One of the
primary changes to the forecast this morning was to increase the
area of snow mention on Wednesday morning for locations mainly
along/north of a LaSalle/Peru to Schaumburg line, as well as
issuance of a Lakeshore Flood Watch.

Ongoing strong warm and moist advection in the mid-levels Wednesday
morning should be supporting widespread precipitation. The
potential vorticity (PV) anomaly with this system has a classic
boot shape on all NCEP models as it moves into the area Wednesday
morning, which align with the system center deepening and
acquiring a slight negative tilt already by this time. There is
some spread on where the heaviest axis of precipitation and its
associated dynamic cooling will be, most favored somewhere over
north central Illinois. Within that area, forecast soundings
indicate the column could easily become cool enough for a
changeover to a wet but heavy snow. It appears conditional on that
heaviest axis being enough duration to cool the column. If this
occurs, warm surface conditions in the immediate low-levels will
likely limit impacts on paved surfaces.

While still plenty of forcing for precipitation Wednesday
afternoon, ingredients for mesoscale forcing for snow will likely
wane, and so have mainly rain during that time. While 0.50-1.25
inches of rain are forecast across the area during Wednesday and
Wednesday evening, where the heaviest stripes are will have to be
resolved as we near the event. Precipitable waters are high (around
an inch), but not off the charts. The wet antecedent conditions
are what cause some concern for flooding issues. Think this will
not be a flash flooding situation, but more of fields,
creeks/rivers, and low-lying areas that could see problems.

There is fairly good agreement on the surface low being near
Terre Haute by early evening Wednesday. The low-level warm sector
would remain to our south, but potential for convection will be
realized north, and cannot rule out some hail during the day in
the southeast with this.

An increasing northeast wind, with afternoon gusts to 35 mph will
make it feel raw for April, and see most areas in the north
struggling to reach the low 40s. The winds will further increase
as they turn more northerly Wednesday night, with gusts to 40 mph
probable, and gusts to 50 mph likely along the lakefront areas as
Wednesday night progresses.

A second upper jet axis will dig in behind the upper low Wednesday
evening, which is forecast to cause a second push to a system
negative tilt over the Lower Great Lakes region by Thursday
morning. Model guidance is in good agreement with this, with the
00Z EC having trended further north/northwest, which is key as
that had been a bit of an outlier. This Wednesday night into
Thursday morning time will be when the forecast area is under the
system deformation. With the increasing unidirectional northerly
flow, the column looks to cool from north to south across the CWA
Wednesday night, and see snow becoming more likely, especially in
an area where frontogenesis and instability can be realized in
this deformation. Right now, northeast Illinois and northwest
Indiana overnight Wednesday night and early Thursday morning are
in an area where that is juxtaposed on several model solutions.
Have trended with more snow mention in the forecast, but again
with accumulation it is highly dependent on enough forcing to
overcome warm near surface air and surface temperatures. Snow
ratios will be very low, with any snow being very wet. But in an
axis of heavier, slightly longer duration forcing, could see a
quick few inches of snow in a localized area. In looking at CIPS
analogs, over half of them for this system have some accumulating
snow in part of the CWA.

The winds look to be their strongest overnight Wednesday into
Thursday morning with gusts of 40+ mph, especially over northeast
Illinois and far northwest Indiana. Near the lake front will
certainly see higher given a northerly orientation off the
frictionless lake. About an 8mb gradient is forecast across the
southern half of the lake Thursday morning, similar to the
northerly flow Oct 31, 2014 event which brought 50+ mph gusts
near the lake front along with some isolated tree damage in
northwest Indiana. So will need to monitor for high wind
conditions and a watch will have to be considered today. Would
see at least an advisory being needed.

The winds will be oriented very well with the fetch of the lake,
in fact likely a little better than that Oct 31, 2014 event,
which brought lakeshore flooding to parts of Chicago and far
northwest Indiana. In addition, lake levels are running slightly
higher than that event, and the precursor onshore flow of
Wednesday will likely build a baseline wave level/surge higher
than that event started with. So given those concerns have felt
comfortable enough to issue a Lakeshore Flood Watch for Cook and
northwest Indiana for late Wednesday night through Thursday
evening, just to raise awareness of that potential.

Precipitation will be ending from west to east during Thursday as
the system pulls away. Sun is expected on Friday, and in classic
spring fashion in the Midwest, we then head into what looks like a
significant warm up for the weekend. Southwest flow in global
guidance brings 850mb temperatures to +15C or higher by Sunday,
which this time of year can support 70. Have highs near or at that
on Sunday and Monday.

.AVIATION...
For the 18Z TAFs...

Concerns
- MVFR clouds today
- Rain starting tonight w/ t-storms possible late into early Weds
- Cigs lowering to IFR and possibly LIFR
- Increasing northeasterly winds
- Mixed precipitation near RFD

Aviation concerns initially are limited, but ramp up considerably
later tonight and through the day Wednesday and even into
Thursday. MVFR clouds will continue to stream southward this
afternoon in wake of departing low pressure. High pressure behind
this low will nose in from the northwest and will shift winds to
north-northeast through tonight while the clouds then slowly lift.

Focus will turn to a strong upper low across the Texas panhandle
that will shift to the Great Lakes region Wednesday. Expect a band
of showers to break out ahead of this low tonight. Instability is
limited initially, but there could be a few thunderstorms late
tonight into early Wednesday. The main push with this first batch
of precipitation will be through midday. Snow may mix in near KRFD
but it will be rain most areas and no accums are expected.

Surface low pressure will strengthen through the period and shift
to central Illinois Wednesday afternoon. Expect northeast winds to
respond with gusts in the afternoon in the 30s. Expect off and on
rain through the day.

For the flying radar screen: Expect to see snow falling in some
areas as early as later Wednesday evening, but will save those
details for a future discussion.

.MARINE...
209 PM CDT

A strong system will impact the Great Lakes beginning
Wednesday and continuing into Friday. Expect an extended period of
gale force winds with an embedded period of storm force winds. The
peak winds expected late Wednesday night into Thursday.

A strong low pressure system over the southern plains will
strengthen as it moves to south of Lake Michigan Wednesday night
into Thursday. Expect northeast gales as early as Wednesday later
afternoon. The low will move into northwest Indiana late Wednesday
night into Thursday, which will shift winds to northerly. This will
also be the period where storm force winds are most likely. Expect a
rapid buildup of waves across southern Lake Michigan, approaching
20 ft. Expect gale warnings and storm warnings to be issued.

This low will strengthen further as it moves to the eastern Great
Lakes, and therefore gales will likely continue through at least
midday Friday. High pressure will bring some relief later Friday
into early Saturday, with winds shifting back to southerly for the
weekend.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

.DAY ONE...Today and Tonight.

  No hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.

Wednesday...
  Limited Flooding Risk.
  Limited Severe Thunderstorm Risk.
  Elevated Non Thunderstorm Wind Risk.
  Limited Snow Risk.
Thursday...
  Elevated Non Thunderstorm Wind Risk.
  Elevated Frost Risk.
  Limited Snow Risk.
Friday...
  Elevated Frost Risk.

DISCUSSION:

A large weather system will move over the area Wednesday into
Thursday, with the primary impact most will experience being
wind. Gusts will reach 40 to 45 mph late Wednesday night
into Thursday morning, with gusts of 50 to 55 mph near the lake
shore. This will produce high waves near the lake front,
potentially causing lakeshore flooding.

Rainfall on already wet ground may cause localized flooding, as
well as likely bring increases on area rivers which are already
running high.

There is potential to see late season snow with this system. On
Wednesday morning, this is for areas mainly north of a Peru to
Chicago line, where sharply reduced visibility could occur. For
Wednesday night and Thursday morning, snow is possible area wide,
with the better chances for sharply reduced visibility and some
accumulation east of a Woodstock to Pontiac IL line.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be necessary through tonight.
