A line of showers and thunderstorms is moving across East-Central Colorado towards Western Kansas. Storms may become stronger tonight as they move across the area.
Another upper level disturbance will move across the region late Monday into Monday night, prompting the development of showers and storms over portions of the area. Severe thunderstorms and heavy rainfall are possible. Confidence in thunderstorm coverage and severe weather potential are below average. Residents and travelers are encouraged to monitor the severe weather forecast as the weekend progresses.
Thunderstorm activity this evening and overnight may greatly affect thunderstorm development, coverage and distribution on Sunday. As a result, confidence in severe weather potential and coverage remains below average. Latest available guidance indicates a scenario characterized by relatively low thunderstorm coverage over northwest Kansas and southwest Nebraska Sunday afternoon, suggesting that severe weather in the NWS Goodland warning area may be isolated in nature (i.e. not widespread).. mainly occurring between 3-9 pm MDT / 4-10 pm CDT. Very large hail and damaging winds appear to be the primary hazards. A brief tornado cannot be ruled out. Broadly speaking, guidance continues to indicate that severe weather potential increases with eastern extent into central Kansas. In other words, areas located along and east of Highway 283 are most at-risk.
Thunderstorms will develop along the Colorado Front Range and Palmer Divide late this afternoon (Saturday May 18, 2024). Thunderstorms are expected to increase in coverage and progress eastward into western Kansas this evening and overnight. A few severe storms are possible… mainly in the highlighted (yellow) area between 7 pm MDT this evening and 3 am MDT Sunday morning. Wind gusts up to 65 mph appear to be the primary severe weather hazard. A few instances of quarter sized hail are also possible. Locally heavy rainfall can be expected with any storms.
