AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
1136 AM CST Mon Dec 17 2012

...UPDATED AVIATION DISCUSSION...

.DISCUSSION...

Near term focus is on the very low clouds in place, and the potential
for this moisture to build down a few hundred feet and cause
widespread dense fog to develop. This was the reasoning behind the
dense fog advisory that was issued yesterday evening when models were
indicating that this would happen. While this has not yet occurred,
it's not out of the question that we could still see a repeat of
yesterday's foggy conditions right around sunrise when temps could
cool off a degree or two. Therefore will hold onto the current
advisory in case this does occur since this would have a high impact
on the morning commute. If visibilities do not worsen by sunrise then
the advisory will likely be dropped.

Fog or not, today looks to be another day of low clouds sticking
around longer than models indicate which will keep temperatures
cooler than model guidance. However, the passage of a mid-level
shortwave and a low-level ridge that will build in behind it should
finally bring some clearing this afternoon. A few light showers ahead
of this shortwave may clip parts of western and central Missouri
through the morning. Broad ridging will build into the area on
Tuesday with mostly clear skies and temps rebounding into the 50s.

Turning to the potential winter storm for Wednesday night, not a lot
has changed in the past 12 hours regarding the global models (ECMWF,
GFS and GEM) and their respective ensembles, all of which remain
fairly tightly clustered on a surface low track from northern
Oklahoma into eastern Missouri Wednesday night. This maintains
above average confidence that rain will overspread the area Wednesday
afternoon, changing to snow across northeast Kansas and northern
Missouri overnight. However, NAM remains a stubborn outlier, taking
the low track further north across northwest Missouri instead. This
would result in mostly rain for the entire forecast area aside from
some light snow on the very back side. Its outlier status against
the tightly clustered solutions of the other models make it difficult
to give it much weight. However, similar scenarios have unfolded the
past few winter seasons in which a southwest low ended up maturing
further north and west than model consensus, so I wouldn't throw out
the NAM solution just yet. That being said, will continue to weigh
the forecast toward a ECMWF/GFS blend which would suggest the best
chances for a few inches of accumulating snow from the St. Joseph and
northern KC metro into north central Missouri, tapering to a dusting
across central MO where the changeover to snow would not occur until
the system pulls out late Weds night. Regardless of which model
solution ends up verifying, one of the biggest concerns with this
system will be the strong northwest winds behind it which could gust
as high as 40 mph Thursday morning. This will likely lead to blowing
snow concerns wherever snow ends up falling, even if there's only an
inch or so on the ground. Should the southern solutions verify, we
could be dealing with a significant blowing/drifting snow event
Thursday morning especially across northern MO.

Broad ridging will be quick to build into much of the Central U.S.
behind this system and maintain its hold on our weather for the
remainder of the extended. This will spell dry weather and
temperatures near or slightly above average heading into the pre-
holiday weekend.

.AVIATION...

For the 18Z TAFs: stratus continues to erode early this afternoon,
and should completely dissipate early this afternoon at all locations
other than STJ. Into this evening and overnight, VFR conditions will
prevail as southerly winds begin to increase. Mid-level clouds will
begin to stream eastward in response to a weak clipper system moving
through NE/IA.
