Severe thunderstorms are not expected on Sunday. ...Synopsis... A strong shortwave trough will lift northeast across the northern Plains on Sunday while evolving into a closed upper low, as several weaker perturbations move quickly east within a strong mid-level jet from the Pacific Northwest into the central Rockies. An associated surface low will lift north from the northern Plains into Manitoba during the day. Despite very minimal instability, isolated thunderstorms will be possible across the upper Midwest where strong deep-layer ascent will develop via low-level warm advection and lift with the upper trough. Isolated lightning strikes may also occur near the coast from northern CA northward. Scattered thunderstorms will be possible in the general vicinity of a surface front from FL west to the central Gulf Coast, where weak instability (generally less than 750 J/kg) is expected to be present. Although low-level moisture will increase across eastern portions of TX/OK Sunday within strengthening southerly low-level flow, a pronounced capping inversion will be present and this is likely to preclude thunderstorm development despite gradually increasing instability. ..Bunting.. 03/01/2024 Read more View the full article Quote Link to comment Share on other sites More sharing options...
