.DISCUSSION...
Issued at 401 PM CST FRI FEB 5 2016

Short Term (Tonight - Sunday):

Shortwave trough moving down into eastern NE will track southeast
and through the CWA overnight. A generous supply of mid/high clouds
will overspread the region. An area of snow which formed ahead of a
separate h7 vorticity max will advance eastward with the southern
edge skirting across the far northern tier of counties. Progged
soundings reveal the snow will be battling a very desert-like sub-
cloud airmass. So, snow amounts will be quite light. Further south
where above freezing temperatures are noted some sprinkles are
possible over west central MO. By mid/late evening most if not all
of the precipitation should have evaporated.

Otherwise, clouds will clear from west to east Saturday morning
with shortwave ridging quickly moving in across the plains. Should
see some modest warming with max temperatures well into the 40s.

Medium/Long Term (Sunday night - Friday):

Fast on the heels of Saturday`s deamplifying shortwave ridge is
a fast moving shortwave trough that will quickly amplify/deepen
Sunday night into Monday in response to a couple of upper level speed
maxima in excess of 100kt. The resulting amplified flow will tap
into a very cold airmass over northern and central Canada. Blended
forecast has trended colder and believe it may not be cold enough.
Have gone a bit below guidance for Monday min/max temperatures,
especially considering extensive stratus cloud cover and the
likelihood of flurries/snow showers.

Fortunately, the cold shot looks of short duration as temperatures
should begin to moderate by mid-week as the Canadian high pressure
moves east of the CWA. Thinking close to seasonal values by
Wednesday, then a bit of warm air advection to get us into the 40s.
After Monday night the rest of the forecast looks dry.

.AVIATION...(For the 06Z TAFS through 06Z Saturday Night)
Issued at 1133 PM CST FRI FEB 5 2016

Weak cold front entering far northwest Missouri will cause winds to
veer to the west-northwest over the next few hours. Moisture is
lacking below 8000 feet so no low-clouds or precipitation is expected
with this front. MVFR ceilings over southeast Nebraska could briefly
make it as far south as STJ or the KC area Saturday morning, but VFR
appears more likely.
