Marine Weather and Tide Forecast for Pottawattamie Park, IN

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 /06Z TAFS THROUGH 06Z SUNDAY/
Issued at 1222 AM EST Sat Feb 28 2026

Cold front is currently passing through the area and primarily VFR conditions are expected through the day Saturday. There is some chance for MVFR stratocu during daytime heating but suspect degree of dry air in place will keep any lower clouds scattered.
Some weak fgen is expected to move across the area Saturday evening and could bring some brief rain/snow and MVFR ceilings but here again degree of dry air and overall weak forcing lowers confidence in impacts. Much better chance of MVFR ceilings is expected late Saturday night as CAA ramps up.
