Update
A small area of thunderstorms was exiting the southern milwaukee
area. Isolated showers ending.

Marine
A small area of thunderstorms was moving across the near shore
and open waters between north point light house and wind point.

Gusts to 35 knots still possible til 10 pm. Otherwise gusty west
winds have diminished. Could see gusts to near 25 knots on Tuesday
again and may need another advisory. Gusts to around 20 knots are
likely Wednesday, staying just under advisory levels.

update...

aviation(00z tafs)...

scattered showers and isolated thunderstorms will diminish this
evening.

Clouds will decrease overnight, with a very similar setup expected
on Tuesday. Breezy winds, increasingVFR clouds, and an afternoon
chance of showers and isolated thunderstorms will occur once
again tomorrow.

Marine...

a small craft advisory has expired as the gusty west winds have
begun to diminish could see gusts to near 25 knots on Tuesday
again and may need another advisory. Gusts to around 20 knots are
likely Wednesday, staying just under advisory levels.

short term...

tonight and Tuesday... Forecast confidence is high:
scattered showers and isolated thunderstorms will slide into the
area mid to late afternoon, winding down early this evening.

Clouds will linger into the evening, with some clearing expected
overnight.

Tomorrow will be very similar to today as another wave moves
through. Expect increasing clouds, with another round of afternoon
scattered showers and isolated thunderstorms. Winds will be breezy
again as well, though probably a tad less than today. Temps
tomorrow will be fairly similar, maybe a couple degrees cooler
than today.

Long term...

Wednesday... Forecast confidence is high.

The trough with that upper low will shift off to the east and
southern wi will have dry weather with plenty of sunshine and
lighter west winds on Wednesday.

Thursday through Friday... Forecast confidence is medium.

A warm front will lift northeast into southern wi Thursday
afternoon and evening. This will be the focus for showers and
thunderstorms all the way through Friday as the front stalls over
our area. The setup looks favorable for decent instability, so
this will be the time period to watch for severe storm potential.

The front should sag south on Friday, although the 12z ECMWF keeps
it stalled over southern wi. Lighter winds should allow for a
lake breeze. Then northeast winds are expected to rush down the
lake Friday night.

Saturday through Monday... Forecast confidence is low.

There are several different scenarios for how the weather will
play out this coming weekend. A chance of showers and maybe some
thunderstorms in the forecast seems reasonable.

Aviation(18z tafs)...

still expecting scattered showers and isolated thunderstorms to
move in this afternoon, lingering into early evening as a wave
moves through. Ceilings will remainVFR. Breezy winds will ease
late afternoon into the evening hours.

Clouds will decrease overnight, with a very similar setup expected
on Tuesday. Breezy winds, increasingVFR clouds, and an afternoon
chance of showers and isolated thunderstorms will occur once
again tomorrow.

Marine...

a small craft advisory remains in effect into early evening when
gusty west winds will settle down. Could see gusts to near 25
knots on Tuesday again and may need another advisory. Gusts to
around 20 knots are likely Wednesday, staying just under advisory
levels.

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.
