Marine Weather and Tide Forecast for Louisville, TN

DISCUSSION
Issued at 236 PM EST Fri Nov 6 2026

Visible satellite imagery highlights scattered stratus and cumulus over the region. These are tied to a broad trough over the Great Lakes region within the northwest cyclonic flow. Moisture is limited and precipitation is not expected outside of a few sprinkles. High temperatures will top out in the mid to upper 60s this afternoon.
Forecast soundings hint at a non-zero chance for patchy dense fog development in SW VA and NE TN, but scattered skies likely linger overnight tonight that could help limit fog development.

On Saturday, there is a signal for weak frontal passage that will bring another round of scattered clouds Saturday afternoon and evening. A few sprinkles can't be ruled out but dry low level air will likely limit actual precipitation. Temperatures top out in the low 60s. Sunday will be similar, but slightly warmer and mostly clear skies. The week ahead starts out with mild & dry weather conditions as we will have to look upstream for signals of a pattern change. The pattern begins to change on Wednesday as a deep trough digs in across the West Coast mid-week. This will amplify the mid- level pattern to with an impressive ridge forming over the west- central NOAM. We will see an trough drop out of Great Lakes region and cut off over the SE CONUS as an omega-like blocking pattern takes shape. Where this trough is centered over will likely see cooler, cloudier pattern with an increase chance of showers. For us, our highs will cool from the upper 60s in the first half of the week to the upper 50s and lower 60s in the second half. We'll monitor the situation to see how the finer details play out, but it's safe to expect cooler, cloudier weather as we head into next weekend.
