Marine Weather and Tide Forecast for Monterey, IN

DISCUSSION
Issued at 242 AM EDT Mon Mar 23 2026

The region will continued to be plagued with these dramatic changes in temperature as upper level ridging across the SW U.S expands east through the week, limiting significant amplification of a series of northern stream waves that will move east in the coming week.

In the wake of the departing trough, some weak convergence and lingering post frontal moisture has resulted in an area of drizzle across central portions of the area. Have added patchy drizzle for the time being with temps likely hovering near or just above freezing. CAA will continue with highs today 20 to 30 degrees or more colder (mid 30s near Lk MI to mid 40s inland)
than yesterday. Temps then rebound into mid week with the next trough set to move in Thursday/Thursday night. Ahead of this, temperatures will likely be in the 70s and med range models hinting at better low level moisture (60 degree or higher dewpoints) and a more favorable timing of the cold front to possibly pose a threat of more widespread showers/storms and may some strong to severe storms. Plenty of time to watch, but something to monitor in the coming days.

In the wake of this system, yet another large drop in temps occurs Friday with slow moderation into the weekend.



AVIATION /06Z TAFS THROUGH 06Z TUESDAY/
Issued at 121 AM EDT Mon Mar 23 2026

Cold advection takes over tonight and an MVFR stratus layer hangs tough into this morning as a result. With high pressure working into the area, plenty of dry air takes over and expect VFR conditions to prevail by midday at FWA and earlier at SBN.

With the northwest winds, sustained winds stay greater than 10 kts and gusts will be stronger than 20 kts until the evening. The approaching high pressure center allows trajectories to turn more easterly after 00z tonight.
