Marine Weather and Tide Forecast for Louisville, TN

DISCUSSION
Issued at 1215 AM EST Sat Feb 28 2026

A gorgeous start to the weekend yesterday will continue into today with mostly sunny skies and high temperatures a few degrees warmer. Mid to upper 60s will be common with a few readings in the lower 70s. A rather weak frontal boundary will move through Sunday. However, precipitation will primarily remain to the north, with possible low end chances of rain for far northern reaches of the forecast area. Temperatures a touch cooler, with the greatest difference/noticeable change across the north, where the cold front will have already crossed at peak heating of the day.

Rain chances for the rest of the area return during the week next week, with repeated shortwave activity moving west to east across the middle of the country. A potentially more pronounced system moves in towards the latter part of the week, under a stronger shortwave trough. Monday onward will at least present a slight chance of precipitation each day through the end of the forecast period.

Though we are a ways out for specifics on next week's precipitation, something we're the most assured of are much warmer temperatures to come. The forecast period may round out with mid to possibly, upper 70s for the valley. 80 degrees may even sneak in there somewhere, especially for the southern valley.
This would be in the neighborhood of 15 to 20 degrees above normal for early March.
