national weather service milwaukee/sullivan wi
330 am cdt thu apr 3 2025

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...

low pressure of 29.3 inches over lake superior will pull away to
the northeast today, while high pressure of 30.2 inches begins to
build in from the west. gusty west to southwest winds are expected
today as a result, especially this morning into early afternoon
when a gale warning is in effect. lighter winds are expected
friday under the high, as it strengthens to 30.4 inches. breezy
winds are expected at times over the weekend as low pressure and a
cold front swing through the region.

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...

a surface low of 29.2 inches will progress toward lake superior
over the next couple of hours, moving into ontario by early 
tomorrow morning. at this time, some areas of patchy fog are 
present over the lake, with the lowest drops invisibility along 
the western shoreline. winds will turn southwesterly after 
midnight tonight & mix areas of fog out.

30.1 inch high pressure will build into the northern great plains
tomorrow afternoon, allowing winds to turn more westerly across 
the open waters. there is increasing potential for a period of 
gales in the far north early tomorrow lasting into the afternoon.
thus we have issued another gale warning for the northern parts 
of the lake from 9-19z. winds will become light & variable
tomorrow night as the high crosses lake michigan. winds will 
shift out of the northeast on friday as low pressure forms in the 
southern great plains. winds will increase during the day on 
saturday as the low moves into the ohio river valley. gales aren't
forecast at this time, though trends will be monitored. periods 
of rain will accompany the approaching low friday afternoon 
through saturday, with a few thunderstorms possible over far 
southern lake michigan.
