...AVIATION UPDATE...

.SYNOPSIS...
Issued at 300 AM CST Thu Nov 23 2017

An area of light mixed precipitation, including some brief sleet,
moved over parts of eastern Iowa into northern Illinois during the
overnight hours. A mostly cloudy sky and south breeze held
temperatures up mainly in the low 30s.

&&

.SHORT TERM...(Today and Tonight)
ISSUED AT 300 AM CST Thu Nov 23 2017

Brief mixed precipitation will end shortly over the northwest
Illinois counties. There are no travel impacts with very little
precipitation reaching the ground from the mid-level cloud deck.

Otherwise, expect a surface trough passage with modest WAA and
afternoon highs in the 40s to around 50 degrees far southwest.
Southerly winds will increase tonight ahead of the next frontal
boundary, with lows from 30 to 35 degrees.

.LONG TERM...(Friday through Wednesday)
ISSUED AT 300 AM CST Thu Nov 23 2017

Few changes to the long term forecast as the end of November into
the beginning of December will be quiet across the area.  Overall
quiet weather pattern is forecast.  Mid next week a wave is forecast
to advect into the area.  There are discrepancies between different
models so confidence in precipitation is low.  The main forecast
concern will be potential record high temperatures on Friday.
Current guidance has temperatures just below record highs in the
upper 50s to mid 60s.  There is real potential that we could break
these records, especially if we mix deep enough.

.AVIATION...(For the 12Z TAFS through 12Z Friday Morning)
ISSUED AT 630 AM CST Thu Nov 23 2017

A southwest wind will become westerly through the day as a surface
trough passes. High clouds will be common with VFR conditions
through the TAF period.
