open lake forecast for lake michigan national weather service milwaukee/sullivan wi 920 pm cdt Wed apr 23 2025
for waters beyond five nautical miles of shore on lake michigan.

Synopsis -
a weak cold front will work across the open waters of lake michigan overnight into Thursday morning, allowing winds to shift north to northeast. Some fog may develop over portions of the lake overnight into early Thursday morning as well. The north to northeast winds will continue through Thursday night, as high pressure around 30.4 inches builds into the northern great plains.
low pressure around 29.9 inches will then move northeast across southern lake michigan on Friday morning, bringing gusty northerly winds behind it for Friday afternoon and night. Gales appear unlikely at this time. Breezy conditions will continue through Saturday, with winds tapering Saturday night, as strong high pressure around 30.5 inches builds in from the northern great plains.

Area Forecast Discussion National Weather Service Northern Indiana 511 PM EDT Wed Apr 23 2025
KEY MESSAGES
- Above normal temperatures will dominate the vast majority of the next 7 days, with briefly "cooler" temperatures in the wake of each disturbance.
- A period of showers and storms remains likely Friday, but some timing difference exist. Severe weather is not expected at this time.
- A threat of strong to potentially severe storms exists Tuesday into Tuesday night. Timing, coverage and overall intensity details remain uncertain at this point in the forecast.
DISCUSSION
Issued at 243 PM EDT Wed Apr 23 2025
Remnants of small area of showers from this morning has finally worked inland, but higher cloud bases and little more than an occasional sprinkle confirm the dry layer is holding strong. While this may continue to progress east over the next couple of hours, don't anticipate measurable precip with it. The cloud cover from this area has limited heating in NW sections with temperatures in the 50s to low 60s versus other areas currently into the 70s. A quick warmup should occur once the cloud break up or shift east but 70s could be a bit of a challenge.
The remainder of the forecast will be dominated by impacts of a a longwave trough still well off the western US coast that will move east over the next several days, eventually developing a closed low that tracks across the SW US late in the weekend into early next week. Upper level heights will increase further with a period of generally above normal temperatures as a persistent SW flow remains in place. A weak disturbance still is set to work into the area Friday, but models are differing somewhat on exact timing of the best chances for showers/storms with some of the CAMs indicating the best chance associated with an area of increasing lapse rates in the morning, with this activity then suppressing development in the afternoon. Others show the best coverage in the afternoon. With triggering features rather subtle and overall flow/instability is sufficient but also not overly strong, have no choice for now but to maintain the likely to cat pops with an anticipation of further refinement in timing in coming forecasts. Severe storms do not appear to be a concern at this point.
A brief cooldown occurs behind this feature for Saturday, with upper level heights quickly recovering as the closed low works slowly east. We should remain dry until Tuesday as the main stream of better lift and dynamics remains west through Monday. While signals are there for plenty of moisture ahead of the trough as it pushes closer by Tuesday, med range models differ somewhat on the filling of the trough with an overall weakening trend likely to take place with time. New model blend reflects this with previous likely pops now more in the mid to high chc range, which is preferred in these later periods when confidence is lower with regards to convection.
SPC placed the area in a Day 7 (Tuesday) 15% severe prob. Northern extent of this could be somewhat overdone, but of any of the systems in the next 7 days or so this has the best potential to bring strong to severe storms. For now, monitor later forecasts.
AVIATION /18Z TAFS THROUGH 18Z THURSDAY/
Issued at 505 PM EDT Wed Apr 23 2025
A large area of high pressure will remain east of the region as a weak cold front moves south and becomes stationary just to the north of SBN. Kept winds light out of the south for now at SBN with the front just to the north by the end of the TAF period.
The low and mid layers of the atmosphere will continue to be very dry and not be able to support much in the way of clouds through Thursday.
