SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1257 AM CST Fri Nov 10 2017 Valid 111200Z - 121200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the U.S. on Saturday. ...Synopsis... Initially zonal flow aloft over the U.S. will gradually amplify on Saturday, as an upper trough off the western Canada coast moves slowly south while evolving into a large closed low. As this occurs, downstream ridging will increase across the Rockies in the wake of an also-amplifying short-wave trough moving out of the Rockies and into/across the north-central states. At the surface, high pressure will remain predominant across the country, with only a weak surface reflection of the aforementioned short-wave trough crossing the center of the country. While showers are expected over parts of the West, the only risk for inland thunder should remain confined to the Florida vicinity. Here, easterly/onshore low-level flow may result in a couple of thunderstorms evolving -- particularly during the afternoon near an east-coast sea-breeze boundary. Severe weather is not expected. ..Goss.. 11/10/2017 Read more
