Short term (today and tonight)
issued at 342 am cst Wed dec 12 2018
at 3 am, the nighttime microphysics satellite loop was showing
mainly water clouds west of the mississippi river and ice clouds
across the remainder of the area. As the upper level low moves
across the area, the ice in the clouds will gradually dissipate
this morning across the remainder of the area. Soundings continue
to suggest there will be some light icing at the onset along the
mississippi river. This precipitation will then transition to
snow along and north of the interstate 90 corridor. As the low
pulls away during the mid to late morning, there could be another
period of freezing drizzle. With the system being a bit slower to
saturate, the precipitation, snow, and ice totals were lowered
some. The freezing drizzle will produce a light glaze of ice.

Snowfall total will be up to an inch with the highest totals in
central wisconsin. With a slippery commute still expected for some
this morning, no changes were made to the existing winter weather
advisory.

Long term (Thursday through Tuesday)
issued at 342 am cst Wed dec 12 2018
on Thursday and Thursday night, the 12.00z models continue to
struggle on whether there will be any interaction between the
northern and southern streams. The ECMWF and gem are a bit
further north with its precipitation on Thursday afternoon.

Soundings suggest that any precipitation during this time period
would be mainly rain.

On Thursday night, there is general consensus that some
precipitation will fall across southwest and central wisconsin.

The NAM even has some precipitation spreading into northeast iowa.

It also much higher with its QPF with totals up to a quarter of
an inch. At this time, thinking the NAM is an outlier so went with
a blend of the gfs, gem, and ecmwf. Some guidance suggests that
there maybe even some light icing. However, soundings suggest that
there will ice aloft, so went with just a dusting of light snow.

The next chance of precipitation may be Tuesday as a shortwave
trough moved through the region. However, with the GFS being the
only model to have it, confidence is very low that it will even
occur.

Throughout this time period, temperatures are expected to be
mainly above normal.

Aviation (for the 12z tafs through 12z Thursday morning)
issued at 547 am cst Wed dec 12 2018
a weather system moving through the area will bring a mix of
sn fzdz this morning at klse as bands of precipitation form and
shift north through the site. A light glaze of ice is possible.

Further west, only low-level saturation is expected with a lack
of cloud ice. Thus, icing and a supercooled liquid layer will be
found over krst through the morning. Should the air mass closer to
krst be able to produce larger drops, some fzdz could occur.

Confidence is not high enough to include the fzdz in the krst
forecast this morning.

After 18z, the TAF will be dry at both locations as the system
shifts east. Overnight there are some signals for ifr clouds and
fog to develop. Krst looks to be in a more preferred location but
for now have hung MVFR clouds in the forecast. Later forecasts
could include ifr conditions by Thu morning.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
