forecast discussion for routine afternoon forecast issuance

Short term Tonight and Thursday
issued at 223 pm cst Wed nov 22 2017
mid to high level clouds ahead of the next fast moving clipper
system already spreading over the state this afternoon. At 2
pm, scattered snow showers were noted upstream over northern
minnesota and far western wisconsin primarily along the 850
baroclinic zone. Little or no snow accumulation noted upstream so
far this afternoon. Best WAA or isent lift region arriving a bit
faster this afternoon so started chc pops a bit faster over
central wisconsin later this afternoon. These snow showers were
moving into a rather dry air mass so the start time will continue
to be challenging.

This dry air mass both at the surface as well as periods of mid
level drying at the onset and then as the system WAA wanes late,
may produce some light freezing type overnight. Since the progs
measurable pcpn has backed off from previous runs, will also back
off a bit on the mention of a freezing type at this time in terms
of a time period. The drier low levels may be just too much to
overcome. Upstream reports indicate all snow at this time as well.

Surface ridging and gradual upper height increases on Thursday
will produce decreasing clouds. Redeveloping WAA pattern later
Thursday ahead of the next system over the northern plains will
start another warming trend.

Long term Thursday night through Wednesday
issued at 223 pm cst Wed nov 22 2017
low amplitude flow aloft across the northern CONUS is forecast
through at least early next week. Model solutions start to diverge
early in the week.

Warm advection ahead of an approaching surface system, along with
a mid level short wave, will bring a chance for rain showers to
the area on Friday. Much warmer than normal temperatures are also in
store, with highs forecast to be about 15 degrees above normal. A
passing cold front will keep temperatures mainly in the 30s across
the area on Saturday, and some lake effect snow showers are
possible in north central wisconsin. Another round of warm
advection ahead of the next surface system will bring much warmer
temperatures back again for Monday.

More uncertainly surrounds the rest of the forecast as models
start to diverge, but the blended solution has a cold front moving
through wisconsin on Tuesday with chances for rain and or snow
across much of the area during the day. Snow chances remain,
mainly in north central wisconsin, on Tuesday night into Wednesday
morning. Highs Wednesday should be close to normal.

Aviation For 18z TAF issuance
issued at 1044 am cst Wed nov 22 2017
patchy MVFR CIGS were persistent across parts of
far northern and northeast wisconsin late this morning.

OtherwiseVFR mid level clouds will prevail across the area
through this afternoon. A quick moving clipper type of system
dropping into the area tonight may generate a brief period of MVFR
cigs and vsbys due to snow showers.

Grb watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
