...AVIATION UPDATE...

.SYNOPSIS...
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 12Z TAFS through 12Z Wednesday Morning)
ISSUED AT 609 AM CDT Tue Apr 24 2018

Mid and high level clouds will be common through the day with a
north wind near 10 kts. Lower ceilings of 5000-7000 ft agl are
expected by early evening at KDBQ/KCID. There is a low probability
of a light shower at these locations during the late afternoon.
