KEY MESSAGES

- Drier air today and Saturday will keep maximum heat index values in check although afternoon highs will remain in the mid to upper 90s. Dewpoints will increase again Sunday.

- Precipitation chances will be near zero this weekend and very low through next week as high pressure remains centered nearly overhead

- A weak "frontal" boundary will bring some drier air back into the region Wednesday through late next week.

DISCUSSION

(Today through Friday) Issued at 1231 AM CDT Sat Sep 19 2026

An upper ridge has helped to suppress showers and bring in the somewhat drier air. Albeit it above normal, we are experiencing more pleasant conditions this early morning with temps in the 70s and dewpoints mostly in the 60s. Fortunately we will have another day with somewhat drier air before moisture works its way back in on Sunday. The upper ridge will weaken somewhat as it shifts westward, and an upper trough will move westward off the Florida Gulf Coast.

As we see a gradual return of moisture, we could also see isolated PoPs return to the forecast. Chances overall will remain low due to the influence of the upper ridge, however it will not completely shut out the chance of some diurnally driven activity.

Mid next week, we will have another shot at drier air as a weak boundary sweeps through the area. With antecedent conditions being a bit drier, not much in the way of showers and storms are expected as the boundary quickly sweeps through. However, northerly winds will prevail from then to the end of the week, with temps finally falling.. To only 4 to 7 degrees above normal instead of 6 to 13 degrees above normal.

AVIATION

(06Z TAFS) Issued at 1231 AM CDT Sat Sep 19 2026

VFR conditions prevail through the TAF period with calm to light variable winds expected.

MARINE

Issued at 1231 AM CDT Sat Sep 19 2026

Light east to southeasterly winds and low seas will prevail through Tuesday along with very low precipitation chances as high pressure remains in place across the northern gulf. A weak frontal boundary will push through the coastal waters mid week, with breezy northeasterly winds developing in it's wake.

FIRE WEATHER

Issued at 1231 AM CDT Sat Sep 19 2026

Drier air will remain in place across the region through today with minimum RH values ranging from 30-40% away from the immediate coast this afternoon. Moisture will increase once again Sunday into Monday.

With little to no rainfall expected through the period, it will not be out of the realm of possibility to see worsening drought conditions.
