.DISCUSSION...
ISSUED 1013 AM CST Fri Feb 21 2014

Tweaked grids a little this morning. Gradient remains strong
between retreating low over Lake Superior and high pressure
centered over the lower Mississippi River Valley. Winds have been
gusting near 45 mph at times along the I-74 corridor. As low moves
further away, winds should gradually drop off this afternoon.

Current highs are in line with new MAV guidance and will not make
any changes at this time.

.AVIATION...
ISSUED 1128 AM CST Fri Feb 21 2014

Pressure gradient weakens through the remainder of the day and
winds should slowly diminish as surface low over Lake Superior
continues to gradually push away. Weak fast moving lobes of
vorticity rotating around deep James Bay upper low will bring
brief periods of cigs and possible -SN to area TAFs late tonight
into Saturday morning. As might be expected, timing between models
differ substainially. Will broadbrush at this point with a PROB
group for the I-74 terminals. Late in the period, windshift to
300-350 degrees is likely as next cold front pushes into
Illinois. Will include at KPIA but leave out elsewhere as shift
should occur close to end of TAF valid times.

.PREV DISCUSSION...
ISSUED 323 AM CST Fri Feb 21 2014
Dynamic storm system moved through the region yesterday and
overnight with the main cold front well out to the east and the
occluded low center over nrn Wisconsin this morning. A small wave
rippling around this morning in the wake of the cold front
bringing some light snow and may continue through the morning
hours. Other than that, forecast is mainly a slow chill beyond
today and tomorrow as another push of cold air comes to the
Midwest. As far as precipitation, several shortwaves are hinted in
the models, but timing is not very consistent. Best consistency is
for Monday/Monday night, with the chance for accumulating snow.
Beyond Monday, temperatures fall below normals in the extended for
next week. At this point the forecast in the extended is dry, but
as it is also increasingly NWrly flow, expect to eventually see a
couple of short waves creep into the forecast.

SHORT TERM...Today and tomorrow...
A short break in the frigid temperatures as the max temps will
climb above freezing heading into the weekend. Clearing this
morning should result in a sunny afternoon, but clouds redevelop
for tomorrow so partly cloudy skies will keep temps from
increasing too much over todays max. Tonight and tomorrow night, a
quick shot for snow across the northern tier of the CWA as
shortwaves ripple through in the wake of the exiting low. Both
shots at precip should result in less than a half of an inch of
accumulation.

LONG TERM...Sunday through Thursday...
Relatively dry but beyond the weekend the operational models are
shearing out some energy across the center of the country and
setting up a weak boundary in parallel flow. Agreement btwn GFS
and ECMWF for the existence of a Monday/Monday night system, with
major issues with the timing. At the end of the NAM run, but the
NAM is leaning into the same solution. Just another quick shot of snow
with a clipper-like system from the WNW. Colder air moving in as
well, as flow amplifies and Midwest sees northwesterly flow
reestablish Tuesday night/Wednesday. Temperatures from midweek on
drop below seasonal normals again.
