Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF WESTERN/CENTRAL OKLAHOMA SUMMARY Widely scattered severe thunderstorms capable of large to very large hail, locally damaging wind gusts, and perhaps a few tornadoes are possible in parts of western into central Oklahoma Saturday afternoon and evening. Sparser large hail and damaging wind occurrences are possible across the Gulf Coast states, the northern and central High Plains, the Great Lakes, and possibly mid-Atlantic. Plains A flat upper ridge will be present today over the southwest states and southern Rockies, while stronger flow aloft extends from the northern Rockies into the mid MS Valley and eastern states. The cold front that triggered convection over OK on Friday has stalled over north TX and will slowly return northward through the day today. Despite relatively weak low-level winds, dewpoints will climb through the 50s across western OK leading to an axis of moderate CAPE by late afternoon. Strong heating along/behind a diffuse dryline will likely lead to isolated thunderstorm development. Steep mid-level lapse rates and strong deep-layer shear will promote supercell storm structures capable of large hail. Given the weak forcing aloft, storm coverage is likely to be rather sparse through the evening. But those storms that can persist will be in a progressively more moist and sheared environment that could support the risk of a tornado or two. Elsewhere farther north, steep low and mid-level lapse rates will promote a risk of scattered high-based afternoon thunderstorms capable of gusty winds and hail from eastern WY/CO into western NE/KS. Gulf Coast Clusters of thunderstorms are ongoing this morning over parts of LA/MS/AL. This activity will persist through the day and spread eastward. Limited heating and rather weak shear profiles will limit the overall severe threat. But nevertheless a few storms may occasionally become intense - capable of gusty/damaging winds and hail. Lower Great Lakes and Mid Atlantic A large upper trough will track from Ontario into Quebec today, while the associated cold front sweeps southeastward across the lower Great Lakes region. Sufficient instability is forecast to support a line of thunderstorms forming over Lakes Erie/Ontario and spreading into parts of OH/PA/NY this evening. Gusty winds and small hail are expected, with a few reports of severe wind/hail possible. A corridor of moderate surface heating will extend from central VA into NJ today, helping to destabilize this region and lead to widely scattered afternoon thunderstorms. CAM solutions suggest the storms that form will struggle to organize/intensify, but there will be sufficient CAPE/shear to support some risk of a damaging wind gust or two through early evening.
