open lake forecast for lake michigan national weather service milwaukee/sullivan wi 304 am cdt Thu jun 20 2024
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 -
patchy dense fog is possible across the southern half early this morning. Patchy dense fog is possible once again overnight tonight into early Friday morning.
light northeast winds will continue across the lake tonight into Thursday night as high pressure around 30.4 inches sits over lake superior. Low pressure of 29.6 inches developing in the central high plains Friday will then allow a stationary front to develop across the open waters, producing periods of Thunderstorms. Low pressure will lift into southern minnesota on Saturday, leading to gusty southerly winds and continued periods of Thunderstorms across the lake. Winds shift southwesterly into Saturday night, and westerly on Sunday as low pressure departs to the east.

KEY MESSAGES

- Continued hot/humid with scattered storms

- Very warm and windy Saturday; Heat Advisory extended

- Showers and Thunderstorms Saturday night

- Dry and somewhat more comfortable Sunday through Tuesday



DISCUSSION
Issued at 340 AM EDT Thu Jun 20 2024

- Continued hot/humid with scattered storms

Radar shows scattered storms moving east of US-131 and north of I-96. These formed southwest of GRR earlier in an area where low level lapse rates were maxed around 5.5 c/kg and LI's were around -5c. These storms will move out of the cwa by 12z.

Surface obs indicate a weak cold front is located near M-46 and moving south. Convergence near this boundary coupled with various weak outflow boundaries will continue to produce convection today.
Additionally, northeast winds behind the frontal boundary will converge with lake breeze boundaries that develop behind the wave of low pressure that the GFS/ECMWF have for a couple of days showed that moves ENE along the frontal boundary and that will likely result in more showers/storms today. PWATs are progd close to 2 inches again this afternoon, so a heavy rain threat exists.
Indeed, local probability matched mean from the 00z HRRR shows the potential for 1-2 inch rainfalls in the heavier cells that develop. The rain loading could also result in some stronger wind gusts.

South of the frontal boundary, heat and humidity will remain with heat indices 95-97 degrees.

Temperatures will fall to around 60 tonight over the northern cwa that will be influenced by the northeast winds from Lake Huron.
Elsewhere lows will fall into the upper 60s. Generally dry conditions are expected tonight.

Friday will see highs 85 to 90 with heat indices 94-96 degrees.
The weak frontal boundary from today will move north Friday generating more scattered convection. Given PWATs aoa 2 inches, a heavy rain threat will exist.

- Very warm and windy Saturday; Heat Advisory extended

Breezy warm sector will overspread Southwest Michigan on Saturday as a warm front lifts into nrn Lwr MI with a cold front situated to our west from near MSP to DSM. Southwest wind gusts of 30-35 mph possible in the afternoon once deeper mixing gets going within tightening, cyclonic sfc pressure gradient. Much of the day should be dry, at least near and south of I-96, with highs in the lower 90s away from Lk MI. The heat advisory over srn sections has been extended into Saturday to account for this final surge of hot air.
Highest pops will be up near U.S. 10, closer to the sfc warm front.

- Showers and thunderstorms Saturday night

A shortwave preceding the primary H5 trough approaching from the northwest comes through on Saturday night along with the sfc cold front. While deep layer shear values around 35 kts would support the possibility of strong to severe storms, it's questionable how much instability will be available given the late-night frontal passage.
Either way will have high pops (60-90 percent) during this time.

- Dry and somewhat more comfortable Sunday through Tuesday

We eventually dry out on Sunday behind the cold front with temps and dew points falling to more comfortable levels. A surface high moves in for Monday and that may keep things dry into Tuesday as well.
However pops ramp up again by midweek as the next cold front and H5 trough drop in from the northwest. An even cooler air mass looks to follow that front by around Thursday of next week with dew pts dropping into the 40s.l move north Friday and spur scattered convection. Once again heavy rain will be possible given PWATs aoa 2 inches.



AVIATION /06Z TAFS THROUGH 06Z FRIDAY/
Issued at 153 AM EDT Thu Jun 20 2024

VFR prevailing much of the time over the next 24 hours although brief periods of MVFR/IFR are possible if and when any of the widely scattered showers and storms impact a terminal. The most likely timeframe for thunderstorms is later today between roughly 20Z and 02Z, and mainly near and south of a GRR to LAN line. MKG should be excluded from the thunder threat later today due to a stable onshore/lake breeze. Scattered showers and storms weakening and ending after sunset then the main concern will become areas of fog and stratus developing overnight, especially where rain occurred.

MARINE
Issued at 340 AM EDT Thu Jun 20 2024

High pressure over Lake Superior will produce a very weak pressure gradient during the next couple of days resulting in low wave heights. Southwest winds will increase Saturday ahead of the next cold front and may pose a threat to boaters and beachgoers.


GRR WATCHES/WARNINGS/ADVISORIES
