Severe thunderstorms are likely on Saturday across the Southern Plains. Heavy to excessive rainfall is possible across the Pacific Northwest.
With a strong low intensifying over the Southern Rockies, southerly flow across much of Oklahoma and Texas will allow for ample moisture to be present. With unseasonably warm temperatures, as the cold front associated with the low pressure system moves east through Saturday, severe thunderstorms will be possible across portions of the Southern Plains. Storm initiation in the form of supercells are forecast during the early afternoon with hail, damaging winds, and tornadoes possible. Thunderstorms will quickly evolve into a squall line, posing a mainly damaging wind risk.
With the area of low pressure off the coast of the Pacific Northwest, heavy to excessive rainfall is forecast to continue. Accumulations of 2-4 inches will be possible, with locally higher amounts in excess of 6 inches.
