423 am cdt Fri sep 20 2019

Short term
Today through tonight... Forecast confidence is medium to high...

areas of dense fog will continue to impact most of southern
wisconsin this morning before lifting 2-3 hours after sunrise.

Milwaukee, racine, and kenosha counties should avoid significant
reductions in visibility as there is a bit more cloud cover and
larger dewpoint depressions. Otherwise mostly quiet conditions are
expected today into tonight. There is a slight chance for a
few thunderstorms this afternoon across most of the area.

Questions will be if we can break the cap in place. Some warm air
advection seen at 850mb this afternoon may help provide some lift
for thunderstorm development. Summer temperatures will continue
this afternoon with highs expected to get into the low 80s for
most of the area.

Saturday and Sunday... Forecast confidence medium.

A strong upper trough over the WRN usa will lift newd through the
nrn great plains and then ewd across SRN canada for the weekend.

Its associated cold front will move across SRN wi for late Sat nt
into sun. Another upper trough will then approach from the great
plains on Sun and across the area Sun nt-mon am. Showers are
likely with scattered tstorms for Sat as a weak band of PVA and an
increasing LLJ and moisture transport move into the region. More
widespread convection and heavy rain is then expected Sat nt-sun
am especially over far SRN wi which saw flooding rains last week.

Very high pws of 1.5-2.0 inches are forecast. While the mean flow
will be fairly strong, the LLJ is aligning with the upper flow
allowing for weak corfidi vectors. Training showers and storms are
expected and a flash flood watch may be needed for far SRN wi.

Long term Monday through Thursday... Forecast confidence medium.

The upper trough will be moving away on Mon but will have to watch
for broken stratocumulus formation as least for the morning hours.

500 mb height rises through the day should lead to sunny skies
for later in the afternoon. A sfc ridge will shift ewd across srn
wi for Mon nt.

Another strong and large low pressure area will move across srn
canada for tue-wed, aiding swly flow and warm advection for SRN wi.

The weak cold front will then pass Wed aft-nt. High pressure will
follow for thu. Another warm advection pattern may quickly move
back into the area for later thu. Only low pops are forecast at
this time for Tue nt-thu.

Aviation(09z TAF update)
Areas of dense fog are impacting most of southern wisconsin.

Expect lifr visibilities and ceilings to continue for most of
southern wisconsin until it lifts by 15z. Mke and sites nearby
may only see visibilities reduce briefly to MVFR around sunrise as
the air is not as saturated. Other than the fog this morningVFR
conditions are expected with southerly winds below 10 knots.

Marine
Southerly flow continues across lake michigan today through
Saturday. Today conditions will be quite calm, but Saturday as the
low approaches expect winds up to 30 knots across the lake. A
small craft advisory will likely be needed for Saturday afternoon
and night. Rounds of rain and thunderstorms are also expected
before the front pushes through Sunday afternoon and evening.

Winds will also decrease and shift to the west to northwest into
Monday.

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.
