KEY MESSAGES

Updated at 144 PM CDT Mon Aug 3 2026

- Elevated fire weather conditions are possible this afternoon and Tuesday across portions of western Oklahoma and western north Texas.

- Low shower and storm chances late Tuesday and Wednesday across northern Oklahoma with increasing chances late this week.

NEAR TERM

(Rest of today and tonight) Issued at 144 PM CDT Mon Aug 3 2026

Temperatures are quickly rising today towards the 90s to triple digits. Drier dewpoints are mixing eastward this afternoon with a strengthening lee trough and breezy southerly surface winds, especially across the western third of the forecast area. Breezy south winds of 10 to 20 mph with gusts up to 25 to 30 mph possible, along with minimum relative humidity values as low as the upper teens to 20s. These dry and breezy conditions may give way to elevated fire weather concerns this afternoon and into the evening across portions of western Oklahoma into adjacent western north Texas.

Convection will develop along a front moving southeastward across the higher terrain late tonight with a shortwave translating eastward across the Northern Plains. Showers and storms will develop along the front move southeastward into southwest Kansas and the Oklahoma Panhandle. The chances are very low for any showers and storms to make it into northwest Oklahoma late this evening into the overnight hours.

SHORT TERM

(Tuesday through Wednesday night) Issued at 144 PM CDT Mon Aug 3 2026

As the upper ridge continues to expand eastward into Oklahoma, expect widespread triple digit heat to return Tuesday. The weak cold front from Monday night will be moving slowly across southwest Kansas and the Oklahoma/Texas Panhandles with dry southerly surface flow ahead of the boundary. Similar to today, lower dewpoints will mix eastward with relative humidity values dropping into the upper teens to 20s. Dewpoints were lowered from the NBM to account for this trend in drier air mixing across the forecast area. Temperatures and heat indices will be borderline Heat Advisory criteria and therefore no headline was issued for Tuesday given the uncertainty in how hot temperatures will rise and a potential for stronger dry air mixing than currently forecast. Showers and storms may develop along the front through the day Tuesday, but chances are low for the activity to push into northwest Oklahoma through the afternoon and evening hours. Low chance (10%) PoPs were added to accommodate any isolated shower or storm that moves into northwest Oklahoma. Cloud bases will be very high based and the main threats would be gusty to strong winds, especially with collapsing updrafts. Additionally, cloud-to-ground lightning could pose a risk for fire starts given low end elevated fire weather returning again across portions of western Oklahoma and adjacent western north Texas due to the hot and dry conditions.

Wednesday, the front will be stalled near the KS/OK state line with similar conditions to Tuesday. However, the dry air mixing may not be as strong with increased chances for a Heat Advisory being needed across portions of the area with widespread triple digit heat. Increased chances for showers and storms to develop Wednesday afternoon and evening across northern Oklahoma along the stalled frontal boundary. Once again, very high cloud bases with a well mixed boundary layer will give way to mostly virga and/or light rain showers with strong wind gusts and dry downbursts as the primary hazard.

LONG TERM

(Thursday through Sunday) Issued at 312 AM CDT Mon Aug 3 2026

Showers and thunderstorm chances increase to 30% on Wednesday night, 40% on Thursday, and at least 60% on Thursday night as the front pushes into northern Oklahoma and becomes nearly stationary. Medium probabilities (to near 40%) extend to the I-40 corridor by Thursday evening. Severe storm potential is being monitored for Thursday, as well, as inverted-V soundings could lead to gusty winds with any storms.

Given the increasing trend in POPs, it is not surprising that uncertainty in high temperatures is also increasing on Thursday through Saturday. High temperatures have decreased over northern Oklahoma on Thursday, and may continue to trend that way if precipitation chances hold or increase. A nearly stationary front setup has an inherent risk of leading to excessive rainfall, but the current uncertainties (e.g., frontal location, timing, and rain chances) are too high at this point to say flash flooding will be a concern.

Other than low rain chances this weekend (primarily Saturday), seasonable temperatures are anticipated.
