Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE SOUTHERN PLAINS SUMMARY Isolated strong to severe thunderstorms could produce hail and gusty winds this evening into the overnight hours across portions of the southern Plains. Southern Plains An upper trough this morning over southern CA/eastern Pacific to the west of Baja California will move east into the southern Rockies by early Saturday morning. Strengthening south-southeasterly 850mb flow is forecast to advect richer moisture northwestward from the Hill Country (50s dewpoints) into parts of west TX northeastward into western/central OK. Steep 700-500 mb lapse rates sampled at 12 UTC this morning in Midland, TX (7.7 deg C/km), will aid in the development of 500-1200 J/kg MUCAPE as the moist plume gradually moistens/heats today. Forecast soundings shows strong to very strong effective shear (50-70 kt), which will support storm organization. Initially, isolated storms are forecast to develop on the northwest periphery of moisture return over parts of northwest TX late this afternoon. As the upper trough approaches the region this evening into the overnight, a more extensive southwest to northeast corridor of convection is expected. One or more clusters will likely evolve into linear bands and move east-northeastward near an eastward-moving Pacific front and from prior storm-generated cold pools. One of these linear clusters seems likely from parts of the Permian Basin vicinity into northwest TX tonight as deeper large-scale forcing for ascent pivots into the southern High Plains. A predominately hail risk with the strongest storms this afternoon/evening will probably transition to a mix of hail/wind potential during the overnight as the storm mode becomes more linear. Strengthening low-level warm-air advection over OK tonight will favor primarily elevated strong to locally severe storms capable of a hail risk into perhaps as far north as southern KS during the pre-dawn hours on Saturday.
