...HYDROLOGY UPDATE...

.SYNOPSIS...
Issued at 244 PM CDT Tue Jun 19 2018

18z surface data has an implied low in northwest Iowa. A front
extended from the low to just south of KMLI and then east into
northern Indiana. A possible meso low was along the front between
KMLI and KC75. Dew points were in the 70s from the Ohio Valley into
eastern Nebraska on south to the Gulf Coast. Dew points were in the
50s and 60s from the Great Lakes into the northern Plains.

&&

.SHORT TERM...(This Evening through Wednesday)
ISSUED AT 244 PM CDT Tue Jun 19 2018

Through sunset, forcing from last nights nocturnal thunderstorm
complex will move east toward Indiana. Areal coverage of showers and
thunderstorms will slowly decrease from west to east. Due to the
high moisture content in the atmosphere, any storm will be capable
of producing heavy rainfall. Based on radar trends, storms will
probably remain progressive which should prevent rainfall from
becoming excessive in any one location.

After sunset, showers and thunderstorms will be possible through
sunrise Wednesday. Another nocturnal thunderstorm complex is
expected to develop. However, all models disagree on where this
development will occur. RAP trends point toward central and eastern
Illinois. The UKMET tries to develop a nocturnal complex in eastern
Nebraska/western Iowa that slowly moves east southeast.

Giving a nod to the UKMET, will go with the idea of another
nocturnal complex developing in western Iowa that moves southeast
into northeast Missouri.

For Wednesday the key will be where the frontal boundary stalls.
This stall will be influenced considerably by the thunderstorm
complex from Tuesday night.

Internally the models suggest the boundary stalling across the
southern third of the area. If correct this boundary would then
provide the focus for storms to persist/develop during the day. As a
result, the highest pops Wednesday are across the southeast half of
the area.

.LONG TERM...(Wednesday Night through Tuesday)
ISSUED AT 244 PM CDT Tue Jun 19 2018

Turning cooler with episodes of showers and non-severe storms through
the period.

Long Term Forecast Confidence Assessment...fair to poor or average
to below average. Main issue is coverage and amount of precipitation
Thursday and Friday. Amounts may be locally up to 1 plus inches over
a 48 hour period with impacts on area highs and lows. Forecast highs
and lows may be off by 5 plus degrees over one or more days depending
on cloud cover with unsettled conditions into next week.

Thursday and Friday...lots of clouds with areas of showers and storms
with heaviest amounts likely along and south of I-80 corridor. Forecast
highs in the 70s seem reasonable with surface low passing south of area
with mins upper 50s to lower 60s. Best estimates are light amounts
far north with moderate to locally low end heavy amounts over a 24
plus hour period with little or no water issues and helpful for area
plant growth.

Saturday through Monday...mostly fair and seasonably cool with highs
mostly in the 75 northeast to around 80 degree range south sections
with moderate humidity levels. Mins in mid 50s to some lower 60s south
sections or slightly below normal with isolated showers and maybe a
brief storm in Northwest upper level flow.

Tuesday...next short wave to arrive with areas of showers and some
thunderstorms suggested with limited instability suggested attm.
Confidence better known on timing in next 24 hours but moderate to
lower end heavier amounts are in long waver trough with mostly
instability to our south.

&&

.AVIATION...(For the 18Z TAFS through 18Z Wednesday Afternoon)
ISSUED AT 1240 PM CDT Tue Jun 19 2018

MVFR/VFR conditions with scattered convection will continue
through 00z/20 with localized LIFR conditions at KDBQ. After
00z/20 the models are unclear as to what will happen. The
scattered convection potentially will grow upscale into another
organized TSRA complex with the potential for IFR/MVFR conditions
through 18z/20.

&&

.HYDROLOGY...
Issued at 244 PM CDT Tue Jun 19 2018

Wapsipinicon River near DeWitt has crested and should fall below flood
stage in about 48 hours or late Thursday or Thursday evening. Heavy
rains of up to 6 inches in Stephenson County impacting the Rock River
which may cause minor flooding at Joslin and Moline in next 36 hours.
A Flood Watch has been issued for these two points as rivers have yet
to respond with a chance a Flood Warning being issued in the next 12
hours as confidence and response becomes better clarified.

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

Scattered thunderstorms are expected to occasionally move across
the Outlook area today and into tonight. The coverage is expected
to be higher along and south of Interstate 80 by this afternoon
and evening. A few storms may become strong to severe with
damaging winds the primary threat. The Storm Prediction Center has
placed areas along and south of the Highway 20 corridor in a
marginal risk for severe weather today.

A more widespread threat will be from very heavy rainfall and
possible flash flooding where the thunderstorms occur repeatedly.
Again, areas more favored for this potential appear to along and
south of the Interstate 80 corridor this afternoon and evening.
The highway 20 corridor which received very heavy rainfall last
night especially in northwestern Illinois, is more prone to flash
flooding should widespread heavy rain-producing thunderstorms can
move across these areas again. But currently only isolated to
widely scattered storms are expect across these northern areas
today and tonight.

Although not quite reaching heat advisory criteria, some areas
south of the Interstate 80 corridor may have heat index readings
in the mid to upper 90s before storms hit and cool things down
later in the afternoon.

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

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

Expect periods of thunderstorms from Wednesday through Friday. The
severe weather risk is low, but additional rounds of moderate to
heavy rainfall may lead to flooding problems.

Flooding is expected to continue on some tributary rivers.
Rounds of heavy rainfall may also cause additional river sites to
rise later this week. Please see the latest Flood Statements and
Flood Warnings for details.

.SPOTTER INFORMATION STATEMENT...

There is a low chance that spotter activation will be needed today
and tonight. Any reports flooding or high water would be
appreciated.
