There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS THIS EVENING ACROSS PARTS OF NORTHWESTERN/WEST CENTRAL OKLAHOMA SUMMARY Evolving clusters of storms may still pose a risk for producing strong to severe wind gusts across parts of the south central Great Plains tonight. 01Z Update.. A weak lee surface cyclone centered across the northern Texas Panhandle and remnant surface boundary, reinforced by convective outflow and differential afternoon surface heating, appear likely to provide the primary focus for strongest thunderstorm development into the overnight hours. Forcing for ascent associated with low-level convergence and warm advection to the east of the low has supported an evolving cluster of storms now propagating east-southeastward into western Oklahoma, in the presence of 20 kt westerly deep-layer mean flow. Due to veering of wind fields with height in lower to mid-levels, deep-layer shear is strong, and further intensification still appears possible as the surface cold pool continues to strengthen, and updraft inflow increasingly emanates from a boundary layer over west central Oklahoma characterized by seasonably high moisture content with sizable potential instability. Upstream, forcing for ascent associated with a weak mid-level perturbation appears to be contributing to increasing thunderstorm development across parts of southwestern Kansas into the Texas Panhandle. This activity may continue to grow upscale this evening, with stronger convective development perhaps becoming focused along outflow trailing the preceding cluster by late this evening, while developing southeastward. Some risk for a couple of tornadoes continues, but the risk for strong, damaging wind gusts will increasingly become the primary potential severe hazard through mid to late evening. Otherwise, though it is appearing more uncertain, the remnant baroclinic zone to the east of the surface low could still become a focus for another evolving cluster of storms later tonight, as it remains quasi-stationary or shifts slowly northward across parts of northern Oklahoma/southern Kansas.
