000 ACUS01 KWNS 200101 SWODY1 SPC AC 200059 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0759 PM CDT Fri Oct 19 2018 Valid 200100Z - 201200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not expected over the U.S. tonight. ...Discussion... Upper troughing is forecast to continue digging southeastward across the Great Lakes and Midwest overnight, with cyclonic flow surrounding the trough gradually expanding to encompass essentially the entire eastern two-thirds of the country by the end of the period. Elsewhere, ridging will persist in the West, though a large -- but weak -- upper cyclone will remain just off the CA coast through the period. At the surface, a deepening low will move gradually across western Quebec, while the trailing cold front continues to shift southward and eastward with time, reaching a position from roughly the Appalachians, across the Gulf Coast States, and into northern Mexico by the end of the period. Showers and thunderstorms continue over portions of the Gulf and portion of Mexico, but onshore lightning has been minimal over the past hour -- limited to the middle Texas coastal area. A few strikes will remain possible overnight across portions the Gulf Coast states -- particularly eastern parts of Texas and into western Louisiana, and possibly portions of the Texas Big Bend/Davis Mountains vicinity. However, most lightning should remain offshore over the Gulf, and south of the Rio Grande, through the end of the period. A strike or two may also occur across eastern North Carolina very late in the period, with possible convection developing ahead of the advancing cold front. However, greater convective development potential will remain offshore over the Gulf Stream. ..Goss.. 10/20/2018 $$
