KEY MESSAGES

Issued at 648 PM CDT Sat Oct 17 2026

- Winds will gradually diminish over land areas tonight but remain strong over the marine areas.

- An increased wildfire risk will potentially continue into Sunday across portions of the forecast area.

- A High Risk of dangerous rip currents return to area beaches tonight and continue into early next week.

UPDATE

Issued at 648 PM CDT Sat Oct 17 2026

Evening surface analysis indicates a 1032mb high pressure system centered over Missouri and a deepening low pressure over the Gulf Stream just east of the North Carolina Coast. The pressure gradient between these two features will keep the pressure gradient tight along the coast with the continuation of brisk winds overnight. Over the marine areas, strong mixing associated with enhanced boundary layer instability beneath the subsidence inversion will keep gale and small craft advisory conditions ongoing.

Further inland, the pressure gradient will begin to relax with these locations in closer proximity to the surface high. This should allow for winds inland to diminish through the evening. Clear skies can be expected to persist through the near term forecast period with low temperatures tonight ranging from the middle 40s over the interior, to lower 50s along the I-10 corridor, and middle to upper 50s along the beaches.

The primary forecast focuses for this evening will be the potential for gale conditions to continue over the 20-60nm offshore Gulf waters through the night and potential high fire danger persisting into Sunday. We will continue to monitor these potential impactful weather situations closely this evening and provide additional updates as needed. /JLH

DISCUSSION

Issued at 154 PM CDT Sat Oct 17 2026

Tonight through Tuesday...A deep, upper level shortwave trough along the East Coast moves offshore and organizes into a closed system (read nor'easter) near the Carolina coast. An upper ridge over the Plains shifts east, to over/near the Mississippi River and builds. This upper ridge will not progress eastward in response to the developing low pressure system off the coast of the Carolina's. Shortwave energy dives into the Southeast U.S. into the mean upper trough trailing south along the East Coast, but with a dry airmass over most of the region, no precipitation is expected. An item to watch is some guidance advertising a shift in the winds to east then southeasterly in the 850-700mb layer early in the coming week. This may bring increased moisture inland over the I-10 corridor on Monday with a potential uptick in rain chances. Northeasterly boundary layer flow is expected into the coming week, helping to temper greater moisture return further inland away from the coast.

A cold airmass that has moved over the forecast area has dropped temperatures well below seasonal norms this weekend. High temperatures will see a rise in the coming week, with around 70 to low 70s Sunday rising to the mid 70s to near 80 by Tuesday, with warmer temperatures over western portions of the forecast area, closer to the upper ridge. Low temperatures are expected to be governed by the dry airmass allowing for efficient nighttime radiational cooling and the light northeasterly flow continuing to bring cooler air southwest over the forecast area. Low temperatures in the mid 40s well inland to low 50s near the coast are expected through Tuesday night.

Wednesday through Saturday, the latest guidance is advertising shortwave energy continuing to dive into the East Coast upper trough. This should maintain upper level troughing along the East Coast with upper ridging further west. This should allow high temperatures to increase to near 80 over eastern areas to the mid 80s over the western half of the forecast area through late next week. Low temperatures will also increase, but still remain just below or near seasonal norms.

Taking a look at the Rip Risk on area beaches, a Moderate Risk is expected to transition to a High Risk as northerly winds over the Gulf transition to northeast to easterly and remain strong. /16

AVIATION

(00Z TAFS) Issued at 648 PM CDT Sat Oct 17 2026

A tight pressure gradient will persist across the area, especially near the coast and at our TAF sites. This will keep brisk north winds blowing overnight into Sunday with sustained winds between 8-13 kts with a few higher gusts up to 20 kts, especially at KPNS and potentially KBFM with greater exposure to the nearby warm waters of Mobile Bay and the Gulf. Winds will again increase by mid Sunday morning as deep mixing commences helping to bring down higher winds aloft in gusts beneath a strong subsidence inversion. Otherwise, expect VFR ceilings and visibilities to persist through the forecast period. /JLH

MARINE

Issued at 154 PM CDT Sat Oct 17 2026

Strong northerly winds will transition to a light to moderate northeasterly over protected waters, strong northeast to easterly over open Gulf waters. The current Gales over marine waters will transition to a Small Craft Advisory tonight. Strong winds over open Gulf waters will mean a SC.Y or SCEC over open Gulf waters into mid week. /16
