Marine Weather and Tide Forecast for Madison, MS

DISCUSSION
Issued at 122 PM CDT Thu Oct 3 2024

Light southeasterly winds will continue to advect Gulf moisture into the region overnight as evidenced by our dewpoints which will creep back into the mid to upper 60s (with PWATs climbing into the 1.5" to 2.0" range -- especially along/south of the I-20 corridor). A weak disturbance riding a stalled frontal boundary along the Gulf Coast will help trigger low to medium (20-50%)
chances for light rain showers late tonight and through most of the day on Friday. The more favored areas for light precipitation will be locations along and south of the I-20 corridor, especially the Pine Belt where coverage will be highest. Rain chances will diminish significantly by Friday evening/night as the boundary sags back to the south and high pressure builds back in from the north. The weekend will be characterized by mostly sunny to partly cloudy conditions, with light easterly to southeasterly breezes maintaining the warm/humid air mass -- with highs ranging from the mid 80s to lower 90s both days.

Sunday night into Monday, a deepening mid/upper trough will shift from the lower Ohio Valley/Great Lakes into the Mid Atlantic, sending a strong cold front through the lower Mississippi Valley.
This will usher in a much more autumn-like cooler, drier air mass as evidenced by dewpoints dropping upper 40s to lower 50s early to mid week. As a result, highs will range from the mid to upper 70s (north) and the lower 80s (south). Model soundings show a very dry profile, so expect rain-free conditions and sunny/clear skies each day.

AVIATION
(00Z TAFS)
Issued at 615 PM CDT Thu Oct 3 2024

VFR flight categories will prevail at most area TAF sites over the next 24 hours. As tropical moisture lifts into southern portions of the area from the gulf, both low clouds and rain chances will be on the increase at namely KHBG and KPIB early Friday morning and through the afternoon. This will result in categories at both locales falling to MVFR/IFR flight categories.
Winds will be calm to light with an easterly component around 3 knots tonight, increasing to between 5-10 knots by late Friday morning. /19/
