Area Forecast Discussion
National Weather Service Quad Cities IA IL
1207 PM CDT Tue Apr 24 2018


Issued at 302 AM CDT Tue Apr 24 2018

A few light showers and sprinkles persisted overnight across parts
of northwest Illinois. Clouds were most widespread along and east
of the Mississippi River. Early morning temperatures ranged from
40 degrees at Independence, to 54 at Keokuk.


.SHORT TERM...(Today and Tonight)
ISSUED AT 302 AM CDT Tue Apr 24 2018

A few light showers or sprinkles may graze the far eastern portion
of the forecast area early this morning with remnant lift and
moisture near with the exiting upper low. Shortwave ridging will
then move across the area with a northerly surface wind at 10-15
kts. Am expecting similar afternoon temperatures as Monday,
generally 69 to 72 degrees, perhaps tempered slightly by some
increasing mid-level clouds associated with another weak upstream
wave. Several CAMS are suggesting this disturbance may support a
few light showers in the far northwest counties late this afternoon.
Have kept any precip out of the forecast for now as day shift can
re-evaluate near term trends. For tonight, expect dry conditions
with near normal lows in the upper 30s to upper 40s.

.LONG TERM...(Wednesday through Monday)
ISSUED AT 302 AM CDT Tue Apr 24 2018

Little change to the long term forecast as quiet weather conditions
with warming temperatures are expected.  The system on Thursday
still is there in the guidance.  Latest runs have slowed the system
down, so temps on Thursday should remain seasonal. With the system
slowed down, it appears most of the area will see precip Thursday
night into Saturday.  Current forecast is for the whole area to see
up to 0.10 inches of rain.

Largest forecast concern for the long term is how warm to go with
temps.  Pattern is forecast to remain Spring and actually warm
dramatically to temps above average.  Temperatures this weekend
could be close to 80 across the area.  Do believe that our green up
will occur quick.


.AVIATION...(For the 18Z TAFS through 18Z Wednesday Afternoon)
ISSUED AT 1204 PM CDT Tue Apr 24 2018

VFR conditions to prevail through the period with some periods of mostly
mid clouds tonight into Wednesday. Winds will be northerly at 5 to 10+
mph through the period.
