open lake forecast for lake michigan national weather service milwaukee/sullivan wi 257 am cdt Mon sep 7 2026
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 -
high pressure around 30.2 inches will allow for light and variable winds this morning through this evening. Meanwhile, low pressure around 29.8 inches over the northern high plains this morning will deepen to 29.5 inches as it lifts northward through the canadian prairies into Tuesday morning. This will allow for gradually increasing southeasterly winds late tonight through Tuesday. Gusts around 30 kt are expected across the northern half Tuesday afternoon through Tuesday night. As low pressure enters the hudson bay Tuesday night, winds shift southwesterly, then westerly on Wednesday as a cold front pushes southeastward through the lake. Winds become northwesterly behind the front, gradually weakening through Thursday and Thursday night. Winds shift to southerly again and increase into Friday as low pressure develops in the northern plains.

- Mostly sunny today, cool tonight
High pressure stretching from western Quebec southwest across the western Lakes will bring another day of tranquil weather with seasonal highs in the upper 70s, followed by lows in the lower to mid 50s tonight. The ridge will then begin to drift eastward tonight.
- Chance of showers/storms Tuesday night/Wednesday, weekend
South winds will increase Tuesday as the surface high moves east and the upper ridge moves overhead. What we'll see is an increase in heat and humidity as temperatures climb into the lower to mid 80s dewpoints rise into the 60s. The upper ridge will be flattened by a short wave moving across the northern tier of states behind a surface cold front. The LLJ increases to 40 kts Tuesday night ahead of the cold front. As precipitable water values increase to 2 inches, we may see some heavy rain develop as convection develops along/ahead of the front. Latest RRFS progs show convection developing over the northern half of the cwa after 06z Wednesday. This is also where the nose of the LLJ is and highest MUCAPE. It's worth noting the GFS is not bullish on CAPE Tuesday night and the RRFS has backed off a bit too. That said, we'll need to watch for localized flooding as the upper flow becomes more parallel to the frontal boundary, which could lead to training echos.
Given the high PWATs, upper short wave, and approaching cold front, PoPs in the 90 percent range seem reasonable late Tuesday night and Wednesday. Once the front moves south Wednesday afternoon, the precipitation will go with it, leading to a couple of dry days late in the week. Highs will fall back into the 70s and dewpoints will retreat to the 50s.
The next cold front will approach Saturday. At this point, models show the best upper dynamics well north into Canada which may result in lower PoPs...20-30 percent...late Saturday into Sunday.
AVIATION /12Z TAFS THROUGH 12Z TUESDAY/
Issued at 617 AM EDT Mon Sep 7 2026
Some patchy fog is possible for the first hour or two before temperatures begin to rise. High clouds are spilling over the ridge and will be present through the period. Fog is again possible after midnight tonight at JXN.
MARINE
Issued at 300 AM EDT Mon Sep 7 2026
High pressure overhead will result in winds and waves well below advisory criteria. However, as the high drifts east late tonight, south winds will begin to increase and a small craft advisory will likely be needed Tuesday afternoon into potentially Thursday.
GRR WATCHES/WARNINGS/ADVISORIES
MI...None.
