Thursday Kicks Off with Targeted Risks

The Storm Prediction Center issued an Enhanced risk for severe thunderstorms across 19,272 square miles from the eastern Texas Panhandle into western Oklahoma.[1] Scattered storms developed late afternoon into evening, fueled by daytime heating and a surface dryline. Large hail up to 2-3 inches in diameter posed the primary concern, alongside damaging wind gusts and isolated tornadoes.

A broader Slight risk enveloped parts of southern and central Kansas plus northwest Texas, where supercells formed amid 40 knots of deep-layer shear and 1000-1500 J/kg of instability. Marginal risks extended farther, touching major cities like Oklahoma City and Wichita. Activity grew upscale overnight into intense clusters moving northeastward.[1]

Friday Heightens Dangers Across Wider Swath

Forecasters elevated the outlook for Friday, designating an Enhanced risk over 82,655 square miles in the southern and central Plains into the lower Missouri Valley.[2] This upgrade reflected stronger upper-level support from a 70-90 knot mid-level jet, boosting tornado potential in eastern Kansas, Oklahoma, and western Missouri. Very large hail exceeding 3 inches and severe winds emerged as top threats.

The Slight risk expanded to 258,291 square miles, affecting over 31 million residents from north-central Texas through the mid-Mississippi Valley. Supercells thrived on 1500-2000 J/kg MLCAPE and high storm-relative helicity. Population centers such as Kansas City, Tulsa, and Dallas fell within the zones. Evening line segments added widespread wind damage possibilities.[2]

Weekend Outlook Signals Continued Vigilance

Saturday brought a Slight risk to the Texas Coastal Plain and upper Ohio Valley, covering 129,935 square miles and 21 million people.[3] Wind damage dominated ahead of advancing cold fronts, with isolated large hail possible in southern Texas Hill Country. Storms shifted southeastward into western Louisiana before moving offshore.

Marginal risks persisted in the Southeast and Tennessee Valley, where short line segments threatened gusts amid weaker instability. Threats tapered but remained notable through early next week, including potential storms into Tuesday across North Texas.[4] The pattern echoed a five-day episode targeting the South and Plains.[5]

Key Threats and Safety Measures

Day	Main Risks	Areas
Thursday	Large hail (2-3″), tornadoes, winds	TX Panhandle, western OK[1]
Friday	Very large hail (3″+), strong tornadoes, winds	OK, KS, MO, north TX[2]
Saturday	Wind damage, isolated hail	TX coast, Ohio Valley[3]

Residents encountered large hail, damaging straight-line winds, and tornadoes as core hazards. Flooding accompanied heavy rain in some spots. The National Weather Service urged monitoring local alerts.

Secure outdoor items before storms arrive.
Prepare a safe room or basement for tornado warnings.
Charge devices and maintain emergency kits with water and non-perishables.
Stay informed via NOAA Weather Radio or apps.
Avoid flooded roads, turning around if encountered.

Key Takeaways
Friday carries the broadest Enhanced and Slight risks, impacting over 30 million.
New SPC intensity groups refine tornado and hail forecasts this season.
Multi-day pattern demands sustained readiness across Plains to Midwest.

This prolonged severe weather setup tested preparedness across a vast region, underscoring the value of timely warnings. What steps have you taken to stay safe? Tell us in the comments.
