Marine Weather and Tide Forecast for Winamac, IN

DISCUSSION
Issued at 152 PM EDT Fri Apr 10 2026

Active weather pattern ahead with a Southeast US ridge sending Gulf moisture poleward, channeled against a desert Southwest trough.

A cool, crummy day to the north of a slow-moving cold front. Here, temperatures have fallen into the 40s with a steady northwest wind.
Farther south, 60s prevail with a continued chance (20-40%) of rain until the boundary clears this evening. High pressure, currently over the Missouri River Valley, moves overhead resulting in a chilly and event frosty night with lows in the 30s. We're still short of our median final spring freeze, and the most recent Michigan fruit reports depicts sensitivity in the 20s, so, we'll continue on headline-free. Warmth in the coming week will rapidly accumulate growing degree days, likely activating the growing season in the days to come.

As high pressure shifts east Sunday, the first of many upper-level impulses lifts through Texas and spills atop the retreating high.
We'll continue to carry 20-30% chance POPs, but know Sunday will not be a washout. Showers, and even thunderstorms, are more widespread Monday as a warm front lifts in. The morning time of arrival and a lack of instability ought to preclude the overall severe weather risk locally. Instead, attention will turn to Tuesday (and Wednesday to a lesser extent) where the Storm Prediction Center is already highlighting a severe weather risk. A much better colocation of ingredients builds Tuesday as low pressure lifts over the Midwest and instability exceeds 1,000 j/kg and shear exceeds 40 knots. This is several days out, and it certainly looks like a scenario where morning showers and clouds needs to clear before any afternoon or evening storm initiation. Stay tuned. The trailing cold front clears our area Wednesday, bringing a continued chance for showers and thunderstorms.

In the wake of this front, little change in the upper-air pattern resulting in a continued flow of disturbances across a Southeast US ridge.

A stalled boundary currently bisects the area from northwest to southeast, extending from Toledo, OH to Fort Wayne, IN to Champaign, IL. A few isolated showers are ongoing out ahead of the front as it slowly sinks southeast, but KFWA and KSBN should stay dry for the rest of the day as the front has already passed. Behind the boundary, winds are coming from the northwest and will gradually diminish after sunset. MVFR ceilings currently persist area-wide and will for the next few hours, although visible satellite imagery shows that clearing is ongoing to our northwest. Expect clearing skies throughout the afternoon and evening, with VFR ceilings returning by 00Z tonight. Light northerly winds and few clouds will make for a very quiet overnight.
