...18z Aviation Forecast Update...

.SHORT TERM...(Today and Tonight)
Issued at 0200 AM CST THU FEB 11 2016

Canadian high pressure will build southward into the region today
in the wake of the clipper system that tracked from the upper
Midwest and across the Ohio River valley on Wednesday.
Temperatures will be seasonably cold today with readings leveling off
if not falling this afternoon across central Missouri.

Another clipper system will slide southeastward from the northern
Plains toward the Ohio River Valley later today and tonight within
the persistent northwesterly flow aloft. This system will bring
light snow to eastern Missouri tonight but expect this activity to
remain east of the Ozarks. However clouds will brush by central
Missouri into the eastern Ozarks at times through tonight.

Forecast certainty is high trough tonight.

.LONG TERM...(Friday through Wednesday)
Issued at 0200 AM CST THU FEB 11 2016

Yet another Canadian high will build southward Friday into
Saturday in the wake of the latest clipper. Temperatures will be
near seasonal levels Friday but below normal Saturday when highs
will remain below freezing across a good portion of the area. Lows
will again fall into the teens Friday night with some single
digits possible in the eastern Ozarks.

As we head into the later part of the weekend, models continue to
depict a progressive upper level trough to impact the region.
Latest model runs are farther north with the primary shortwave and
better lift. However a warm air advection pattern and isentropic
upglide are still progged to provide at least some lift Sunday.
At this time it looks like a good chance of light precipitation
Sunday and Sunday night. The precipitation type remains rather
uncertain but a wintry mix still looks plausible. Any accumulation
looks to be light at this time. Stay tuned to forecast as we head
into the weekend.

A more zonal pattern and a gradual warming trend is expected during
the middle and later part of next week.
