KEY MESSAGES

Updated at 257 AM EST Fri Jan 9 2026 - Fog is forecast to develop once again early this morning and again on Saturday morning primarily across SW Florida and the Lake Okeechobee region. Some of this fog could become locally dense.

- Daytime temperatures will remain above average into the weekend, but below any record values.

SHORT TERM

(Today through Saturday) Issued at 257 AM EST Fri Jan 9 2026

The axis of a persistent upper level ridge will begin to gradually shift east today as stout troughing progresses eastward across the country. Nevertheless, its influence will continue to be felt as we head into the weekend as plentiful dry air remains in place across South FL, and subsidence continues to inhibit any chances for convective activity. Strengthening easterly-southeaterly flow near the surface will continue to advect some low-level moisture into the region as depicted by HREF and ensemble forecast soundings. This moisture will be sufficient to once again present a threat of patchy to dense fog each night, especially over interior portions of the CWA where winds are most likely to decouple. The resulting visibilities could drop below one mile at times with visibility in some areas dropping below one quarter of a mile at times, resulting in hazardous commuting conditions.

The warming trend continues through the short term period, with highs in the low to mid 80s each day, and lows in the mid 50s over the interior, and mid 60s across the East Coast.

LONG TERM

(Saturday night through Thursday) Issued at 257 AM EST Fri Jan 9 2026

A cold front will approach the region Sunday into Monday as the aforementioned trough moves over the Eastern US, bringing increasing chances for rain and cooler temperatures for the entire CWA. Guidance has come into better agreement regarding increasing moisture ahead of the front, and sufficient support to allow for isolated showers and a few thunderstorms mainly along the East Coast and local Atlantic waters. To that effect, kept PoPs in the 20-40% range for Sunday night into Monday. Northerly flow behind the front will advect slightly cooler air over the region through the first half of the week, with highs in the low 70s, and lows in the upper 40s to mid 50s near the interior and in the lower 60s along the East Coast.

The forecast becomes less certain as the week progresses, with some guidance keeping enhanced moisture over the area and trying to develop disturbances over the Gulf, all of which could result in persistent chances for rain Tuesday-Thursday, and generally cool temperatures thanks to the increased cloud coverage. The NBM depicts this scenario fairly well while also accounting for the remaining uncertainty, so we left it fairly unchanged with this forecast cycle.

AVIATION

(06Z TAFS) Issued at 257 AM EST Fri Jan 9 2026

VFR conditions should prevail through the period. Light southeasterly winds will strengthen in the late morning, reaching the 10-15kt range. Some patchy fog could develop across the interior early this morning, but confidence regarding impacts to terminals remains low at this time.

MARINE

Issued at 257 AM EST Fri Jan 9 2026

A moderate easterly-southeasterly breeze is expected across the local waters through the first half of the weekend as high pressure remains the area. A few isolated showers are possible at times but chances will remain low each day. Conditions will evolve towards the back half of the weekend, with winds and seas building ahead of a frontal passage.
