Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1016 AM CST Tue Nov 14 2017 Valid 141630Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the contiguous United States today. ...Coastal Washington/north Oregon... Along an occluding front, morning CAMs consistently depict a QLCS gradually impinging on the Pacific Northwest coast tonight. Ahead of the front, low-level winds will strengthen as an upper low off the BC coast begins to accelerate east. But with paltry buoyancy along the coast, the offshore QLCS will likely weaken and be low-topped with little lightning. The risk for a waterspout moving ashore as a tornado appears negligible. ...Ozark Plateau to Illinois/southeast Iowa... Low-level warm advection will strengthen tonight with sufficient moistening to support weak elevated buoyancy and a risk for isolated to scattered elevated storms after 06Z. ...Florida East Coast... Moist northeasterly flow will support showers and isolated storms along the east coast convergence zone. ..Grams.. 11/14/2017 Read more
