Thunderstorms are not expected across the USA Sunday. ...Synopsis... A low amplitude, mostly zonal, mid-level flow regime will persist across the US Sunday, as weak ridging over the central states shifts eastward. A shortwave trough, embedded within strong westerly flow aloft, will eject into the central Plains as a second, weaker trough approaches the West Coast early Monday. A lee low should steadily deepen over the central Plains and Midwest ahead of the advancing shortwave trough, while high pressure remains steady over the Southeast. Weak moisture return is expected across parts of the Plains and ArkLaTex as the low deepens and moves east. However, low and mid-level lapse rates will remain poor, with strong inhibition negating thunderstorm potential. Elsewhere, little to no buoyancy is expected across the CONUS outside of the near coastal waters of WA and OR. Given the poor lapse rates and weak inland moisture advection, any low-topped thunderstorms that do develop are expected to remain transient and offshore. ..Lyons.. 11/22/2024 $$
