...AVIATION UPDATE...
.SYNOPSIS...
Issued at 336 PM CDT Mon Jun 8 2020
18Z surface data has tropical depression Cristobal in southeast
Arkansas while a very diffuse frontal boundary ran from southeast
Missouri up through central Iowa. Dew points were in the 50s across
the Great Lakes and Ohio Valley. Dew points were in the 60s and
higher from the Gulf coast up into the Tennessee Valley and then
into the Plains.
&&
.SHORT TERM...(This Evening through Tuesday)
ISSUED AT 336 PM CDT Mon Jun 8 2020
Headlines:
A Flash Flood Watch remains in effect from 12Z Tuesday til 03Z
Wednesday for potential flash flooding as the remnants from the
tropical system lifts north through the region with anomalously
high moisture levels leading to heavy rainfall rates. The
northern half of the watch area maintains a later, 18z start time,
following the timing of the onset of heavy rain. This watch area
was expanded eastward a row of counties this morning, based on
uncertainties with the track of the system.
Discussion:
Quiet and dry conditions will be seen through midnight. Attention
then turns to the remnants of Cristobal.
After midnight humidity levels will slowly increase as Cristobal
approach the area. Downward motion ahead of the system should result
in dry conditions through 4 AM Tuesday. Starting around dawn Tuesday
rain should begin moving into the far southern areas with it perhaps
reaching an Ottumwa, IA to Galesburg, IL line by 7 AM.
On Tuesday a large area of rain with overspread the area from south
to north during the day with it 'possibly' ending in the far south
by late in the afternoon. The possibility does exist that the
northeast half of the area 'could' remain dry until mid to late
afternoon. Whether or not this occurs will depend upon the track of
the low pressure center.
Those areas that do not see rain until the afternoon hours will have
the potential to warm into the mid 80s. Where the rain persists
temperatures will likely hold in the 70 to 75 degree range with high
humidity levels.
Right now the strongest winds look to be across the eastern half of
Illinois. But some wind gusts to 35 mph are possible east of the
Mississippi.
Thunderstorms will be possible Tuesday but given should be generally
isolated and embedded within the larger rain band.
As for the overall severe risk; hail is doubtful given the extremely
high freezing levels. Localized damaging winds 'may' be possible if
precipitation loading occurs in the stronger downdrafts. While the
tornado potential is there given the amount of wind shear with
height, it 'may' be dependent upon how much heating can occur during
the day and where a storm develops in relation to the larger rain
shield.
.LONG TERM...(Tuesday Night through Monday)
ISSUED AT 336 PM CDT Mon Jun 8 2020
The influence of the remnants of Cristobal and strong upper level
system that follows will provide continued unsettled conditions
Tuesday night into Wednesday. An upper level northwest flow, then
upper level ridge will then provide an extended stretch of dry
weather with below normal temperatures gradually moderating to near
to above normal early next week.
Tuesday night: The near model consensus now has Cristobal's remnant
low lifting from WI to upper MI, while a new low pressure center
advances from the west under the strong upper low moving through the
central plains. The lack of surface convergence and shortwave
subsidence aloft between these systems will likely keep most of the
area precipitation-free through the night, once the exiting band
moves out of the north in the evening. Thus, pops have been lowered
to slight chances for most of the night, with chances for showers
and possible thunderstorms increasing in the west and southwest
toward morning as the upper level forcing develops ahead of the the
advancing upper level trough. Cooler and slightly drier air may
begin to filter into the area toward morning and forecast lows are
in the upper 50s to lower 60s. With the deeper moisture out of the
area, there will be no significant threat of heavy rainfall.
Wednesday should see a band of showers and isolated thunderstorms as
the main lift ahead of the sharp upper level shortwave moves
through, taking on a slightly negative tilt. This could bring
another quarter to half inch rainfall over mainly the northwest
during the morning. While the surface pressure gradient will
increase during the day, the signal for strong winds is less clear
than earlier model runs. This is due to a weaker, less defined
surface pressure gradient with the surface troffiness in the
morning under the phasing upper level system. Winds will begin to
ramp up by afternoon, possibly into the 20 to 30 mph range, but the
confidence of gusts over 40 mph has diminished. Clouds and low level
cool air advection will hold temperatures in the 70s. Gusty west
winds will continue through Wednesday night night with temperatures
cooling into the mid to upper 50s.

.AVIATION...(For the 06Z TAFS through 06Z Tuesday Night)
ISSUED AT 116 AM CDT Tue Jun 9 2020
Bands of heavy rain will impact the terminals on Tuesday as
tropical moisture overspreads the area. Anticipate MVFR/IFR in
periods of heavier rain and as the low ceilings linger into the
evening. Isolated thunder is possible but did not include in TAFs
with this update due to low confidence on the coverage. Breezy ESE
winds during the morning will abruptly switch around to the WSW
during the afternoon or evening.

.HYDROLOGY...
Issued at 759 PM CDT Mon Jun 8 2020
Rainfall forecast for this system continues to show uncertainty.
This afternoons forecasts moved the heaviest rain west of the area
while some guidance still has our area to get some of the highest
amounts. As a result coordinated with the RFC to keep the
forecasts the same as this AM. This forecast has the heavier rain
in our area. If this doesnt occur then river forecasts would be
too high.

Please see the latest Flood Statements and Flood Warnings for details. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY Periods of heavy rain are likely on Tuesday as the remnants of tropical storm Cristobal move through the region. A Flash Flood Watch is in effect Tuesday for all of eastern Iowa, northeast Missouri and much of far west central and northwest Illinois along the Mississippi River. A widespread rainfall 1 to 3 inches is possible in the watch area with isolated amounts near 4 inches. The heavy rainfall may result in areas of flash flooding and eventual river flooding. There is a slight risk for flash flooding area-wide, but lower rainfall amounts are forecast along and east of the Mississippi River. Also on Tuesday, there is a marginal risk for severe weather area-wide. The primary risk is brief spin up tornadoes. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed today or tonight. DLS
