DAY 1 SLIGHT SEVERE WEATHER RISK THIS EVENING OVER PORTIONS OF CENTRAL KANSAS…FORECAST SYNOPSIS…ISSUED MAY 14, 2026…11:50 A.M. EDT – Image for illustrative purposes only (Image credits: Unsplash)
Central Kansas – A slight risk of severe thunderstorms has been outlined for this evening across portions of the region, with the potential for large hail and damaging winds. The Storm Prediction Center issued the update this morning, highlighting favorable conditions for isolated supercells despite a strong capping inversion that could limit overall coverage. Residents from central Kansas into parts of Missouri and west Texas should monitor developments closely as temperatures climb into the mid and upper 90s.
Why the Risk Emerges Today
A diffuse dryline will stretch from western Kansas into western Oklahoma, setting the stage for hot and unstable air to the east. By late afternoon, forecast parameters align for supercells capable of producing large hail and strong gusts, though weak large-scale forcing keeps confidence in widespread development low. Any storms that do form could turn severe quickly, with the main threats centered on hail and wind rather than widespread tornadoes.
Further south into west Texas and Oklahoma, high-based thunderstorms may develop over hot, dry areas west of the dryline. These cells could produce dry microbursts or occasional clusters with damaging winds, though a strong capping inversion is expected to weaken them as they move east this evening.
Key Parameters Point to Isolated Intensity
Analysis of multiple models shows moderately to very unstable conditions within the outlined area. Surface-based CAPE values range from 500 to 3500 joules per kilogram, while mixed-layer CAPE sits between 250 and 3000. Storm-relative helicity in the lowest kilometer reaches 100 to 200 square meters per second squared, supporting the chance for rotating updrafts.
Significant tornado parameter values remain low at 0.0 to 1.6, consistent with a less than 2 percent tornado probability. Any twisters that develop should stay weak, rated EF0 to EF1 at most. Supercell composite parameter readings climb as high as 35 in spots, underscoring the potential for strong, long-lived storms where initiation occurs.
Timing and What to Watch For
The strongest activity is expected from late afternoon through early evening, when instability peaks. Hail up to two inches or larger remains possible in the hatched areas, alongside wind gusts exceeding 65 knots in the most intense cells. Coverage is likely to stay isolated, meaning not every location will see storms, but those that do could experience rapid intensification.
Forecasters note that the cap east of the dryline will play a decisive role. If it erodes enough in localized spots, supercells could mature; otherwise, activity may remain suppressed or short-lived.
Staying Ahead of the Threat
Local National Weather Service offices will issue updates throughout the day, including any mesoscale discussions or watches. Residents are encouraged to have a safety plan ready, including access to sturdy shelter and a reliable way to receive alerts. The forecast remains subject to change as new data arrives, so checking official sources regularly is essential.
Even with the limited coverage expected, the combination of heat, moisture return, and shear creates an environment where one or two storms could produce significant impacts. Preparation now reduces risk later.
