.AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon)
ISSUED AT 1121 AM CST Thu Nov 23 2017

VFR conditions will be seen through 18z/24 as a weak front and
high pressure move quickly through the Midwest. The 12z/23 model
runs have started to suggest the potential for LLWS developing
09z-15z/24 across eastern Iowa. Given that this trend is new,
LLWS was not included in the 18z/23 TAFs. If this trend continues
to be suggested, LLWS may be needed in later TAFs.
