KEY MESSAGES

- Dense fog will be possible for southern portions of the area this morning, and perhaps again Friday morning.

- There is an increasing fire danger threat for Saturday.

- Mostly warm and dry weather will continue early to mid next week.

DISCUSSION

Issued at 350 AM CDT Thu Mar 26 2026

A mostly warm and dry weather pattern will continue in our region through early to mid next week, thanks in large part to a strong subtropical ridge centered over northern Mexico and Texas.

Concerning dense fog potential: In the near term, the primary concern will be for early morning fog, and potentially dense fog over southeast portions of the area. It is there that recent guidance strongly favor dense fog development in the more humid southerly flow pattern with advection of coastal fog. Have made no changes to the previous limited/elevated fog threat areas in the HWO graphics. Another graphic may be needed for Friday morning.

Concerning fire weather danger: A strong polar cold front will manage to drop in Friday afternoon, and then push through the entire region by Friday evening. Any rainfall associated with the front will be very light and inconsequential. This will set the stage for increased fire danger due to much drier (minimum RH < 25%) and breezy conditions (peak gusts up to 30 mph) following the front as we go through Saturday. With this in mind, we have included an elevated fire danger threat in the HWO graphics, and it is not out of the question that we'll eventually need a Red Flag Warning, especially if mixing overachieves and allows for stronger wind.

Otherwise, the cooler temperatures Saturday should be brief as warm advection increases again and continues through early to mid next week. This should help to boost rain chances, but only for disorganized, and diurnally enhanced shower activity as the subtropical high shifts to our southeast and becomes centered near the FL peninsula. Expect the next polar front to move toward the area late next week with perhaps greater moisture to work with. /EC/

AVIATION

(12Z TAFS) Issued at 533 AM CDT Thu Mar 26 2026

A layer of stratus has made its way over most of the souther TAF sites coming in from the Gulf. As such we have a fog graphic over the effected regions. The stratus layer is expected to dissipate by about 9am this morning, although a thin layer lingering for an hour or two longer can not be ruled out. The other sites are not expected to see any excitement for the period. There is also potential for another bout of stratus for our southern sites tomorrow.
