KEY MESSAGES

Updated at 608 PM EST Thu Jan 8 2026 - Fog is forecast to develop once again tonight into early Friday, 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.

UPDATE

Issued at 111 PM EST Thu Jan 8 2026

No major alterations were made to the previous forecast. The NBM (National Blend of Models) output continues to under-do daily rain chances across South Florida in the current weather regime. While model soundings continue to depict a mid-level subsidence inversion aloft, there will be enough low- level moisture for intermittent periods of isolated (10-20%) shower activity across the region through Sunday, and the forecast has been updated accordingly. The latest CAMs (convection allowing models) show this well depicting light to moderate shower activity advecting across the region from time to time, focusing on the east coast of South Florida later in the work week into the upcoming weekend. Accumulations will remain light across the region as any shower activity will be vertically capped by the subsidence inversion and dry air above.

SHORT TERM

(Today through Friday) Issued at 240 AM EST Thu Jan 8 2026

Persistent upper level ridging will remain in place over the southeastern United States, promoting generally dry and benign conditions across the area through the period. This ridge will maintain a mostly dry air mass and continued subsidence over the region, limiting chances for rainfall. That being said, easterly surface flow could advect enough low level moisture for some stray showers over the local Atlantic waters and the East Coast later this afternoon.

Areas of patchy fog could be possible across the interior once again early this morning given light winds and sufficient low-level moisture. SREF and HREF guidance suggests coverage could become dense in nature in some spots over the interior, with visibility in some areas dropping below one quarter of a mile at times, resulting in hazardous commuting conditions.

LONG TERM

(Friday night through Wednesday) Issued at 240 AM EST Thu Jan 8 2026

The benign weather conditions will extend into the weekend, with near zero rain chances and warm temperatures forecast for Saturday and Sunday. However, a pattern change approaches as deep longwave troughing develops over the Rockies and gradually erodes the ridge on its way east. An associated front will drop along the peninsula early next week, bringing lower temperatures to the region. Highs will max out in the low 70s, while lows could dip into the upper 40s to mid 50s near the interior and in the lower 60s along the East Coast. Guidance at this time shows meager moisture available ahead of the front, which would make for a fairly dry frontal passage.

AVIATION

(00Z TAFS) Issued at 608 PM EST Thu Jan 8 2026

Winds will remain overnight, remaining out of a southeasterly component at terminals along the east coast. Isolated SHRA remains possible at all east coast terminals through the end of the TAF period but confidence in coverage still remains too low for inclusion of VCSH at this time. Patchy FG/BR is also possible across the western half of South Florida tonight into Friday between 06z-15z.

MARINE

Issued at 240 AM EST Thu Jan 8 2026

A light to gentle breeze is expected across the local waters for the next several days as high pressure remains the area. A few isolated showers are possible at times but chances will remain low each day.
