...AVIATION UPDATE...

.SYNOPSIS...
Issued at 310 AM CST Tue Nov 21 2017

Patchy high clouds drifted across the area during the overnight
hours. A southwesterly breeze held temperatures up in the upper
30s to upper 40s.

.SHORT TERM...(Today and Tonight)
ISSUED AT 310 AM CST Tue Nov 21 2017

The main highlights of the short term forecast period are a
frontal passage today with strong winds and steady to falling
temperatures.

The front will push through the forecast area this morning,
accompanied by a 3-4mb pressure rise bubble. Strongest winds are
expected from 9 am into the early afternoon, with the northwest
counties favored for the highest gusts around 40 mph. Bufr
soundings indicate a few locations in the northwest could flirt
with advisory criteria for an hour or two, but for the most part,
winds are expected to stay a bit below criteria (sustained 30 mph
or gusts of 45 mph). Expect morning highs with temps falling off
slowly in the afternoon.

Tonight, the sky will clear with high pressure and a decreasing
wind. Lows will settle in the upper teens to low 20s.

.LONG TERM...(Wednesday through Monday)
ISSUED AT 310 AM CST Tue Nov 21 2017

Little change in the long term forecast as the week looks to be
quiet across the area.  Overall weather for travel across the region
looks to be quiet. Temperatures will fluctuate this week as cooler
highs on Wednesday will lead to a warming trend as a shrtwv trof
advects through the flow on Friday.

Model inconsistency exists between the timing and the strength of
the H5 wave for Friday.  The timing of fropa and possible precip
associated with this wave is still uncertain.  What is certain is
that temperatures in the 50s look likely.  There is also a chance
for highs in the 60s much like yesterday.

.AVIATION...(For the 12Z TAFS through 12Z Wednesday Morning)
ISSUED AT 527 AM CST Tue Nov 21 2017

sweeps through the area. Strongest winds, gusting over 30 kts,
will occur at KCID/KDBQ. Winds will diminish at or below 10 kts by
early evening.
