Marine Weather and Tide Forecast for Lake Michigan Beach, MI

DISCUSSION
Issued at 126 AM EST Sat Feb 28 2026

A cold front will continue to work its way through the area during the overnight hours, leading to a steady decline in temps to the upper 20s / low 30s by daybreak. A disturbance dropping out of the northern plains will bring the chance for snow this afternoon and evening, primarily across Michigan. There should be a pretty sharp gradient on the southern edge of the precipitation initially where low-level saturation is not aided by isentropic accent and Fgen forcing (likely around the MI/IN border). Accumulation of roughly an inch or less can be expected, with minimal impacts. By late evening, PoP coverage will expand south and east as scattered rain/snow showers move into the area thanks to an uptick in PWATs and synoptic forcing.

Surface high pressure dominates the northeast and Upper Ohio Valley to start the week. This will help to shunt a disturbance just to our south Sunday night into Monday morning, with a bulk of the weather remaining over central/southern Indiana. While some slick spots along and south of US-24 can't be ruled out for the Monday morning commute, the expectation is little to no snowfall accumulation will occur.

The rest of the week looks active as several chances for precipitation occurs under a gradually warming temperature regime. Monday night into Tuesday will feature mixed precip types, followed by a transition over to rain as the precip type through the remainder of the week. With 2-3+ inches of QPF possible by the end of the week, it will be a welcome sight for the many drought stricken places in central Indiana and northwest Ohio. Our attention will then need to shift to the possibility of spring flooding as we are expected to remain in a wet pattern through much of March.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/
Issued at 1116 AM EST Sat Feb 28 2026

A low amplitude frontal wave will swing through the lower Great Lakes later this afternoon into this evening. More organized precip associated with an elevated fgen response will pass north of the terminals during this time with dry low levels likely resulting in nothing more than a few sprinkles or flurries expected in northern IN. Cigs will eventually lower into MVFR this evening into early Sunday morning otherwise with northerly winds near 10 knots.
