Marine Weather and Tides
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

The forecast remains on track for this afternoon.
Vfr conditions will prevail through Saturday.
Could see an isolated shower storm through late this afternoon,
with a better chance for scattered storms this evening. Chances
currently look highest along and southwest of a line from the
wisconsin dells to madison to janesville... From mid evening into
early tonight as a shortwave moves through.
It should turn dry overnight into Saturday morning. Not much
forcing for storms on Saturday. Could see a storm or two try to
fire along the lake breeze in the afternoon.

warm temperatures well into the 80s are still on track for this
afternoon. There could be an isolated thunderstorm or two by late
afternoon, but overall still looks like the better chance for
storms will hold off until evening.

mainlyVFR conditions for the TAF period. MVFR conditions are
possible with any showers or thunderstorms. There is a small
chance for a brief shower or thunderstorm for south-central
wisconsin early this afternoon. Confidence is not high enough to
include in tafs. There is a better chance for thunderstorms for
south-central wisconsin after 6 pm and for southeast wisconsin
after 9 pm. Dry weather is expected after midnight. Southwest
winds of 15 to 20 knots are expected today with lighter winds on

showers and thunderstorm activity currently over northwest wisconsin
will weaken as it moves east, staying out of southern wi. The low
level jet will be weakening and there is lower instability to the
There is a chance for showers and thunderstorms, mainly during
the evening. Meso models are trending later with a line of showers
and thunderstorms moving through during the late evening. This is
expected to develop across southern mn and NW wi along weak
surface convergence and within a weak shortwave. The surface
boundary stalls to our west keeping us within the southwest flow.
Regardless, there is plenty of CAPE with 20 knots of 0-6 km shear
to fuel thunderstorms. A few storms may be strong to severe,
mainly toward the west where there is greater instability. We will
lose instability as the evening GOES on and with other dynamics
lacking, showers and thunderstorms will struggle to make it to
Precip chances wind down after midnight.|
Saturday and Sunday... High forecast confidence.
Near record high temperatures are expected Saturday and Sunday,
with highs Saturday around 90, and in the low to mid 90s on
Sunday. A few showers may linger across the far eastern portion of
the forecast area Saturday morning, but otherwise, dry weather
should prevail. Heat indices on both days should top out in the
Monday and Tuesday... Medium to high forecast confidence.
Upper level ridging will nose into the area from the southwest
during this time, keeping temperatures well above normal. A few
thunderstorms may try to sneak into the western portions of the
forecast area, but overall, conditions look dry. Highs Monday will
again be around 90, with slightly cooler (but still well above
average) highs in the upper 80s expected for Tuesday.
Wednesday through Friday... Low forecast confidence.
From Wednesday onward, much of the forecast will be dependent on
the evolution of the tropical disturbance currently located in the
gulf of mexico. Extended guidance differs as to whether this
feature will be shunted off to the east through the ohio valley,
or if it (and a considerable amount of moisture) will be absorbed
by the western trough as it lifts into the great lakes
Wednesday Thursday. A relatively cooler and wetter pattern would
prevail if that feature can make it this far north; otherwise,
above average temperatures and just scattered thunderstorms can be
expected to end the workweek.
Aviation(09z TAF update)...
mainlyVFR conditions expected through the TAF period. Scattered
showers and thunderstorms are expected during the evening,
especially for south-central wi. MVFR conditions are possible with
the showers. Southwest winds will dominate into Saturday.
winds and waves will remain below small craft levels into early
next week. Southwest winds of 15 to 20 knots on Friday
will push wave to 2-3 feet this afternoon. This weekend,
temperatures will be in the upper 80s and dew points will reach
well into the 60s over land. As this air advects over the cool
lake, dense fog remains a possibility.
temperatures will approach record levels over the next few days at
milwaukee and madison. Below are the record high temperatures and

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
