Update
Aviation(12z tafs)
Scattered light rain showers from middle level clouds may affect
taf sites over the next few hours, before dissipating. Otherwise,
expect an increase in clouds by late morning into the afternoon,
with any ceilings around 6000 feet this afternoon.

Another chance for showers are forecast for this afternoon into
early this evening. A slight chance for thunderstorms exists, but
left mention out of tafs due to low confidence in thunder
occurring. Gusty west winds are expected by later this morning
into this afternoon, with gusts to 25 knots at times.

Clouds should gradually move out of the area tonight, with light
west southwest winds. Gusty west southwest winds are anticipated
for Tuesday, with gusts to 25 knots at times.

Prev discussion (issued 324 am cdt Mon may 29 2017)
today and tonight... Forecast confidence is medium.

Models are in pretty good agreement with showing a 500 mb low
sliding southeast across portions of lake superior and ontario
canada today. This feature then shifts to the east tonight.

Cyclonic flow across the region is expected at 500 mb, which will
bring an initial vorticity maximum through the area early this
morning. There may be a few showers with this feature in southern
portions of the area.

Another vorticity maximum should then slide southeast toward the
area later this afternoon, moving through in the evening. Area
forecast soundings, adjusted for the expected temperatures and dew
points, support chances for showers and slight chances for
thunderstorms this afternoon. Mesoscale models may be overdone
with areal coverage, as they tend to be in these situations.

Area of clouds should slide southeast into the area later this
afternoon into this evening, before retreating to the north
tonight. Gusty west winds are expected today as well. Highs today
should reach the upper 60s, with lower 70s across far southeast
wisconsin. Lows tonight should be in the upper 40s to lower 50s.

Tuesday... Forecast confidence is medium
the mid level and surface lows will lift north across of ontario.

Several waves of vorticity will move through the region and weak
frontogenesis and some instability results in shower and thunder
chances. It will be a tad cooler. 850 winds will be 25-30 knots and
steep low level lapse rates will promote mixing and breezy west
winds.

Wednesday and Thursday... Forecast confidence is high.

Surface high pressure will slide south of the state bringing mainly
dry weather and sunny skies on Wednesday. Temperatures will rebound
slightly as the upper low loses its grip. Behind the high, southwest
flow will bring a push of warmer and more moist air. Precip and
thunder chances return Thursday night.

Friday and Saturday... Forecast confidence is medium.

A frontal boundary looks to be over the region on Friday bringing
precip and thunder chances. As high pressure moves north of the
state a cold front will push south across the region. Precip chances
linger through Friday evening with convergence along the front. High
pressure will continue slides south across the great lakes on
Saturday. Another surge of cooler air looks possible with the cool,
northeast flow.

Sunday and Monday... Forecast confidence is low.

Models have been flip flopping for this period showing either high
pressure of or a surface low and precip. As a result, a lot of
uncertainty with temperatures too. Easterly flow will keep
temperatures cooler near the lake.

Aviation(06z tafs)...

sct mid level clouds will move across SRN wi early Mon am while
sct-bkn040-050 is expected from late Mon am into Mon eve. Small
chances of showers and a slight chance of a tstorm from late mon
am and through the afternoon. Gusty wly winds expected for mon.

Marine...

a small craft advisory is in effect from 15z today to 00z Tuesday
across the nearshore waters of lake michigan. A tight pressure
gradient will develop during this period, along with robust low
level mixing. This will result in gusty westerly winds. Frequent
gusts to 25 knots are expected. Any high waves will be over the
open waters, given the offshore flow.

Gusty west southwest winds are possible on Tuesday, as the
pressure gradient remains tight, and low level mixing continues.

The gusts may not be as high as today, so there is some
uncertainty. A small craft advisory may be needed for Tuesday. Any
high waves will remain over the open waters once again.

Mkx watches warnings advisories
Wi... None.

Lm... Small craft advisory from 10 am this morning to 7 pm cdt this
evening for lmz643>646.

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.
