KEY MESSAGES

Updated at 254 PM CDT Sun Jul 5 2026

- Strong to severe storms are possible this afternoon and evening across portions of southern Oklahoma and into western north Texas with large hail and damaging winds as the primary hazards.

- Hot and humid conditions expected to continue through next weekend with a risk for heat related illnesses.

NEAR TERM

(Rest of today and tonight) Issued at 254 PM CDT Sun Jul 5 2026

Storms have developed this afternoon in southern Oklahoma and have become more organized. Additional storms are expected to develop through the afternoon hours. Downdraft CAPE in analyzed between 1000 and 1400 J/kg in the southwest supporting strong downdrafts and the potential of strong winds, although hail will still be a threat with mixed-layer CAPE around 2500 J/kg. Deep layer shear is not particularly strong, so many individual updrafts may not be the most persistent, but the overall environment will still support some scattered severe storms. This activity will likely slowly push south and storms become less numerous this evening with diurnal stabilization.

SHORT TERM

(Monday through Tuesday night) Issued at 254 PM CDT Sun Jul 5 2026

The cold front aiding in the development for this evening's storms will push through the area overnight. And while the post- frontal airmass is not cold by any stretch of the imagination, it qualifies as "not-as-hot" and heat index values Monday and Tuesday afternoons will be closer to the 95-100 range as opposed to the 100-105 range. Some isolated showers/storms are not completely out of the question in the southeast tomorrow, but overall precipitation chances are rather low.

LONG TERM

(Wednesday through Saturday) Issued at 135 AM CDT Sun Jul 5 2026

By midweek, the upper ridge will build westward towards the Pacific Coast of Southern Cali. This will bring a return to northwesterly flow aloft and warm downsloping adiabatic heating. Thus, widespread near to above triple digit heat is forecast Wednesday and Thursday. Additionally, diurnally driven thunderstorms along the higher terrain to the west-northwest, driven by embedded disturbances in the flow across the Plains will bring increasing shower and storm chances to Oklahoma, especially western into northern Oklahoma, during the evening and into the overnight hours both days.

The ridge will build northward into the Rockies by the end of the week and into the weekend with a strong shortwave trough across the Plains. This may bring some relief to the triple digit heat and more widespread chances for rain across the forecast area.

AVIATION

(18Z TAFS) Issued at 1236 PM CDT Sun Jul 5 2026

Scattered shower and storms are expected this afternoon and evening in southern OK and western north TX, mainly impacting KDUA and KSPS with potential for strong and erratic winds in the vicinity of storms. Otherwise, VFR conditions and light east/southeast winds are expected to prevail across the area through Monday.
