Marine Weather and Tide Forecast for Florence, AL

NEAR TERM
(Today)
Issued at 359 AM CST Sun Nov 8 2026

Surface high pressure will remain centered across the Ozarks and adjacent parts of the southern Plains through the near term period, with a ridge axis extending eastward from the parent high into the central/southern Appalachians. Although the resultant pressure gradient has enabled a light NNE wind to persist for much of the night, flow has recently become calm at several of our local ASOS/AWOS sites. With an optimal environment for radiational cooling expected to continue through sunrise, conditions will be favorable for development of a patchy-areal coverage of frost, and a Frost Advisory remains in effect until 7 AM CST. In addition to the frost, patchy but locally dense fog will also impact mainly valley locations in northeast AL/southern TN early this morning.
Over the course of the day, the pressure gradient will expand, with winds expected to become calm later this afternoon. Although the coverage of cirrostratus clouds (originating from the southern Plains) will likely increase this afternoon, sufficient insolation should occur prior to this for highs to reach the l-m 60s.

SHORT TERM
(Sunday night through Tuesday)
Issued at 937 PM CST Sat Nov 7 2026

Another medium chance of widespread frost will be forecast Sunday night into Monday as high pressure continues to promote clear skies with calm winds and lows drop into the mid 30s once again.
An additional frost advisory issuance is likely within the next forecast package update. Otherwise, as the Tennessee Valley remains sandwiched between an upper level ridge in the southwest U.S. and an upper level trough in the northeast U.S., sfc high pressure should continue to prevail through the early work week with subsequent dry conditions. Highs are forecast to continue to reside in the upper 60s to around 70 degrees with overnight lows dropping into the upper 30s to lower 40s.

LONG TERM
(Tuesday night through Saturday)
Issued at 937 PM CST Sat Nov 7 2026

A powerful trough will be digging into the eastern CONUS Wednesday into Thursday. This will bring a sharp cold front through Wednesday night or Thursday. Only a low chance of a shower or thunderstorm exist with the front before blustery north-northwest winds occur behind the front. After highs in the 60s Thursday, overnight lows will dip into the lower to middle 30s Thursday Night. Highs on Friday will only reach the lower 50s in valleys and upper 40s atop the Cumberland Plateau. This will be about ~15 degrees below normal. The first widespread freeze of the season will take place Friday night into Saturday morning with lows in the upper 20s to around 30. High pressure will shift southeast into the Gulf States late Saturday, with overnight lows in the upper 20s to lower 30s.

AVIATION
(12Z TAFS)
Issued at 547 AM CST Sun Nov 8 2026

There have been no significant changes to previous aviation forecast reasoning, as conditions will remain VFR at the HSV/MSL terminals for the duration of the valid TAF period. However, based on latest satellite data, we have increased the coverage of high clouds to broken beginning this aftn (and this will likely continue into the early morning hours on Monday). Lgt NNE sfc winds are still expected to become lgt/vrbl-calm by early this aftn.
