Area Forecast Discussion
National Weather Service Quad Cities IA IL
309 AM CDT Mon Oct 15 2018

.SYNOPSIS...
Issued at 308 AM CDT Mon Oct 15 2018

The band of frontogenesis driven light rain/light snow has been
moving through our area since mid evening, and is now mainly east of
the Mississippi River. No ground accumulation has been reported, but
a bit of slush did accumulate on our cars in the parking lot, and
it appears that DVN did have some of the heavier rates around 1 AM.
While the area is seeing cold advection that has lowered
temperatures to the lower 30s, we have not fallen below freezing as
of 2 AM. Clouds remain widespread over the region, well behind the
cold front, and now appear to remain over the area through mid
morning, especially in the north half.

&&

.SHORT TERM...(Today and Tonight)
ISSUED AT 308 AM CDT Mon Oct 15 2018

The light snow band should be well east of the area by sunrise, so a
dry day is in store for the area today. It will begin with plenty of
clouds, but clearing does appear on the way for later this morning
and the afternoon. The clearing will last through much of the night,
resulting in a good potential for a rapid temperature drop this
evening, with temperatures near freezing by 9 PM. The winds will
remain light through early morning, but will increase to 10 to 15
mph by sunrise. That will limit the lows from falling much below the
2 AM temperatures, but could actually make the freezing conditions
more pronounced, as sheltered areas see sub freezing temperature mix
in as well. In any case, until the local area sees a widespread
freeze take place, and since morning isn't working out, we'll have
to issue another freeze warning for tonight.

ERVIN

.LONG TERM...(Tuesday through Sunday)
ISSUED AT 308 AM CDT Mon Oct 15 2018

Long term looks to be a quiet pattern with below average
temperatures.  Largescale flow should remain northwest through much
of the week before it turns southwest for the end of the week.  This
weekend, northwest flow will return to the area and bring cooler
temps for the weekend.  The main forecast concern in the period will
be temperatures and any chances for precip at the end of the work
week.

Friday, an open H5 wave is forecast to move southeast across the
Great Lakes region. At the surface, a cold front will swing
southeast across the region.  Convergence along the front looks weak
and will likely not contribute to much forcing for rain. That said,
while largescale ascent looks enough for precipitation, models show
a dearth of moisture. As a result, the overall chance for
precipitation will be low.  Past this, there appears to be no other
chance for precipitation in the long term.

Model temperature spread is about 5 to 7 degrees for highs.  As a
result there is room for slight changes to temperatures in the long
term.

&&

.AVIATION...(For the 06Z TAFS through 06Z Monday Night)
ISSUED AT 1157 PM CDT Sun Oct 14 2018

Light precipitation in the form of rain and snow along and behind
a passing cold front will change to light snow before ending late
tonight. Low clouds and reduced visibilities due to precipitation
will keep MVFR conditions in place through much of the night. BRL
and MLI appear likely to see a period of IFR conditions before
09z with a round of very light snow. Monday...all sites are
expected to improve to VFR as skies become mostly clear in the
morning.

350 PM CDT Sun Oct 14 2018

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

Bands of rain mixed with snow, and turning over to all snow, will
move across much of the Outlook Area this evening and tonight.
Light snow accumulations up to a half inch are possible especially
west of the Mississippi River mainly on grassy and elevated
surfaces. Although ground temperatures are still mild and will
melt much of the snow, some heavier bursts of snow may still
produce some slushy light accumulations on roads later tonight.
Also with freezing temperatures settling into the area by late
tonight, some localized slick spots may develop on bridges and
overpasses by Monday morning.

With the freezing temperatures and threat to sensitive vegetation
by late tonight, a Freeze Warning has been issued through 9 AM CDT
Monday morning for much of the Outlook area except portions of
west central Illinois.

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

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

More cold nights are on the way, with frost and freezing
conditions likely each night through at least Tuesday night. Once
an end to the growing season has been determined, this threat
will no longer be mentioned in the forecast.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed through tonight.
