KEY MESSAGES

Updated at 1122 AM CST Thu Dec 11 2025

- Locally elevated fire weather concerns today due to low relative humidities and strong, gusty winds. - Roller coaster temperatures into early next week, with multiple cold fronts set to move through the region.

- The strongest cold front in the period moves through late Saturday afternoon into Saturday night. Single digit wind chill values Sunday morning north of I-40. - Precipitation chances remain very low over the next 7 days.

SHORT TERM

(Through tonight) Issued at 1112 AM CST Thu Dec 11 2025

Limited to locally elevated fire weather concerns exist this afternoon given the continued dry low levels and return to well above normal temperatures today aided by the development of strong southwesterly, downslope winds. The current forecast targets a small portion of east central Oklahoma /namely parts of southern Creek, Okfuskee and western Okmulgee counties/ for the worst combination of parameters, including 75th to 85th percentile ERC values. Conditions will improve late afternoon into the evening with the loss of daytime heating and an expected decrease in wind speeds /albeit a modest one/.

Attention then turns to the next cold front, which will move through late tonight/early Friday morning. Winds will shift to a northerly direction and increase in speed for areas north of I-44 by daybreak Friday, although morning temperatures should remain on the high side for this time of year in most locales.

LONG TERM

(Tomorrow through Thursday) Issued at 1112 AM CST Thu Dec 11 2025

The aforementioned cold front will continue to move southward into the day Friday, likely clearing the entire area by midday. A gradient in daytime temperatures is likely to occur, with above normal values hanging on for the southern half of the area and noticeably cooler values for the northern half, especially when considering the increase in wind speeds behind the front. Wind speeds and gusts have been adjusted upward from the NBM initialization using the NBM 75th percentile values for sustained speeds and by mixing in the 90th percentile for the gusts.

Light southerly winds will make a return Saturday to portions of the area but not enough to lead to much of a warmup in most areas compared to Friday. There remains a very low chance of light precipitation Saturday afternoon and evening in southeast Oklahoma and perhaps into west central Arkansas, with the overall chance remaining below mentionable levels for now.

The much advertised strong cold front remains on track to move into the area beginning late afternoon Saturday and continuing into Saturday night. Data trends continue to point more toward the colder solutions, with forecast temperatures combined with strong and gusty winds behind the front leading to apparent temperatures Sunday morning in the single digits for areas north of I-40. Wind speeds and gusts behind the front have been adjusted upward using a similar process to those with the Friday front.

The center of the surface high behind the front will pass well to the north and east of the area, with the surface ridge axis pushing through Sunday night. Southerly winds will return to much of the area by daybreak Monday and likely a non-diurnal low temperature trend Sunday night and into Monday in most spots. The post-frontal airmass looks to be cold enough that highs on Monday should still be below normal despite the south winds. However, above normal temperatures look to return by Tuesday and certainly by Wednesday, continuing through the end of the work week given a reduced meridional flow component in the upper level pattern.

AVIATION

(18Z TAFS) Issued at 1133 AM CST Thu Dec 11 2025

VFR conditions are likely to persist through the forecast period for all sites with FEW to SCT high cloud. Sfc winds remain gusty this afternoon before decreasing overnight ahead of an approaching cold front. LLWS is expected to develop across the region as the LLJ strengthens overnight. The front begins to move through the area by 10z, with winds shifting out of the north and northerly LLWS developing across NE OK sites. By late morning, sfc winds strengthen with gusts again near 20 kts, especially in NE OK.
