new information added to update section

Update
Issued at 658 am cst Wed dec 12 2018
precip band has come together during the past couple hours. But
saturation is deep enough that it is almost all snow. Still expect
some dz fzdz, but probably behind the main band when it will have
less impact. Edged snow totals up a little to account for this. Will
leave the advisory intact since roads will still get slippery.

Temperatures in east-central wisconsin will hover near freezing,
so that should help with efforts to treat the roads there.

Synopsis
Issued at 309 am cst Wed dec 12 2018
a mild period with a wintry mix of light precipitation today, and
possibly again on Thursday night.

The forecast period will begin with strong zonal flow across
virtually the entire pacific, and the westerlies splitting upon
reaching north america. Some buckling of the flow increase in
amplitude will occur over the pacific during the latter part of
the period, though that probably won't be sufficient to have a
significant impact downstream over north america.

The westerly flow will maintain modified pacific air across most
of the conus. That will result in temperatures about 6-12f
degrees above normal across the forecast area. Opportunities
for precipitation will be limited as southern stream systems
with access to gulf moisture remain south of the area, with the
result being below normal precipitation for the period.

Short term Today... Tonight... And Thursday
issued at 309 am cst Wed dec 12 2018
no change to forecast headlines this morning.

A strong, compact shortwave will cross the region today. Despite
strong QG forcing, very dry air through a significant depth of the
troposphere has prevented precipitation from breaking out thus
far. Estimated soundings from central wisconsin continue to trend
toward saturation, so anticipate some precipitation beginning in
western wisconsin in the next few hours. The precipitation should
expand as it shifts east northeast. Determining precipitation type
remains problematic. The strongest lift and heaviest
precipitation is likely to occur with deep saturation, and thus
fall as snow. But lighter precipitation both at the onset and
ending of the event may fall as a combination of snow and
drizzle freezing drizzle (depending on surface temperatures). Will
leave the posted headline intact, though at this point the
likelihood of having a period of fzdz fall heavily enough to ice
over roads and sidewalks has waned since the headline was
originally posted.

Plenty of low clouds and patchy fog will linger tonight as the
system pulls away. The quiet weather will persist Thursday as the
chance for precipitation with the next shortwave isn't expected
until Thursday night.

Stayed close to a broad-based blend of guidance products for
temperatures, with a slight reduction in the diurnal range due to
the expected cloud cover.

Long term Thursday night through Tuesday
issued at 309 am cst Wed dec 12 2018
precipitation chances and types on Thursday night are the main
concerns during this part of the forecast. Flow aloft is expected
to be pretty progressive across the northern CONUS for the end of
this week through early next week. This should help to prevent any
strong surges of cold air from reaching the forecast area, so
temperatures are expected to be well above normal.

A mid level trough is forecast to cross the region as a closed
500 mb low passes to the south. An inverted surface trough will
bring a chance for precipitation to eastern and parts of central
wisconsin Thursday night. There is a slight chance for freezing
drizzle or freezing rain in parts of central and eastern wisconsin
due to a lack of ice crystals, but the model blend emphasizes
snow over any freezing precipitation. No measurable ice is
forecast, but locations generally from the fox valley east to lake
michigan could pick up from 0.1" to 0.4" of snow after midnight.

Precipitation chances come to an end by the start of the day on
Friday and the rest of the forecast is generally dry.

Aviation For 12z TAF issuance
issued at 309 am cst Wed dec 12 2018
low clouds with bases ranging from low-end MVFR to lifr were
fairly widespread across the area, though there were a few breaks
in the low clouds over east-central wisconsin. Anticipate
primarily ifr conditions today as light precipitation moves
through the area, then ceilings will likely lower to lifr over
most of the area tonight as low-levels remain moist and winds
decrease.
