forecast discussion for routine afternoon forecast issuance

Short term Tonight and Friday
issued at 324 pm cst Thu nov 15 2018
a clipper low pressure system and associated cold front will move
through the region tonight into early Friday. This system appears
to be moisture-starved, and rh timesections only show a brief
period (2-4 hours) of saturation at any given location during the
event. Will carry low-end likely pops, as it appears most places
will see a few hours of light snow, but accumulations should be a
half inch or less. The exception will be over vilas county, where
lake-effect snow showers will persist into Friday and boost
totals to around an inch in the northern part of the county.

Will continue the trend of the previous forecast, and mention
only snow for precipitation type. Moisture may shallow out enough
after the steadier snow ends to remove ice crystals from the
saturated layer, but subsidence should preclude development of
freezing drizzle.

Northwest winds will gust to 20 to 30 mph in the wake of the cold
front on Friday.

Lows tonight should drop into the middle to upper 20s, except
lower 30s near the lakeshore. Highs on Friday should range from
the lower 30s northwest to upper 30s in eastern wi.

Long term Friday night through Thursday
issued at 324 pm cst Thu nov 15 2018
the main highlights from this forecast period are the potential
for some light snow showers at the start of the period and the
transition to a northwest upper-level flow.

For the start of this forecast period, a surface low pressure
system will track southeast across iowa, which will impact
southern wisconsin with snow showers. All of the forecast area
should see some snow, with the higher accumulations of 1 to 2
inches focused across vilas county and central and east-central
wisconsin. Snow showers will exit the region to the east by
Saturday afternoon.

A surface high pressure system will then push into the upper
mississippi valley as the low tracks further southeast for the
remainder of Saturday. Aside from the small chances of lake
effect snow across vilas county throughout the weekend, dry
conditions will prevail for the region until Monday afternoon.

This is partially due to the transition to a northwest upper-
level flow beginning Sunday afternoon.

Entering into Monday afternoon, model guidance is not in agreement
with the track of a weak clipper system that may influence the
area. The GFS has the low pressure system tracking across iowa and
is also slightly more aggressive with moisture. The ECMWF has the
low positioned further west over the iowa nebraska border with
very little moisture. Due to the uncertainty, kept slight chance
and chance pops in for Monday afternoon and evening for portions
of central and east-central wisconsin.

For the rest of the forecast period, the northwest upper-level
flow will remain dominate over the upper mississippi valley,
leaving dry conditions to prevail across the area.

Temperatures will remain below normal through much of the forecast
period with an slight increase to near normal temperatures for
Wednesday and thanksgiving.

Aviation For 18z TAF issuance
issued at 1142 am cst Thu nov 15 2018
MVFR ceilings will linger along the lakeshore for another couple
hours, otherwiseVFR conditions are anticpated until late evening.

A clipper low pressure system and associated cold front will bring
light snow to the region starting late this evening (north central
and central wi) and ending early Friday morning (along the lake
michigan shoreline). The snow will probably only last 3-4 hours at
any given location. MVFR local ifr flight conditions will accompany
the steadier snow. Northwest winds will increase and become gusty
after the cold front passes through Friday morning.

Grb watches warnings advisories
None.

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.
