OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
342 PM CDT Sun Aug 25 2019
FOR WATERS BEYOND FIVE NAUTICAL MILES OF SHORE ON Lake Michigan.
Waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.
.SYNOPSIS...
Persistent southeast winds are expected tonight into Monday
between departing high pressure of 30.3 centered over the
northeast US this morning and an approaching low. This will result
in building waves, especially across western portions of Lake
Michigan. Winds will pick up tonight, with gusts to 25 knots
possible.
Gusty south and then west winds are likely Monday night into
Tuesday as the low deepens across southwest Ontario and drags an
associated cold front through the area. Westerly wind gusts of
25 to 30 knots will be possible Wednesday as the low to the north
slowly moves eastward.

A frontal system will then bring periodic chances for rain showers Monday into Tuesday. Thunderstorms are possible. Expect highs in the 70s Monday, and in the upper 70s and low 80s Tuesday. Short term (tonight and Monday) issued at 221 pm edt Sun aug 25 2019 newd pivot of lead convectively augmented SW disturbance over ERN ks this aftn will allow warm frontal zone and attendant deep moisture surge to overspread the region on Monday. Leading warm advection wing should focus remain west overnight as predicated in most model guidance. Otherwise showers likely Monday with lead SW trough warm front lifting through. Long term (Monday night through Saturday) issued at 221 pm edt Sun aug 25 2019 slightly faster consensus solution wrt to ewd cold frontal progression Monday night early Tuesday warrants further pop reductions Tuesday aftn. Poor frontal timing and general cloud contamination should preclude thunder. |
Thereafter robust post frontal drying cooling spreads across the great lakes oh valley through Thursday. Secondary moisture starved cold front follows Friday before pattern aloft briefly flattens and warms early next week. Aviation (for the 18z tafs through 18z Monday afternoon) issued at 154 pm edt Sun aug 25 2019 vfr conditions are expected at both ksbn kfwa through the first portion of the TAF period thanks to high pressure overhead. Warm air moisture advection ramps up overnight as a warm front lifts northward, bringing increasing chances for showers and maybe even a few thunderstorms through Monday.

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. |
