SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0158 AM CDT Sat Oct 31 2020 Valid 021200Z - 031200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not currently forecast across the contiguous United States on Monday. ...Synopsis... A long-wave mid-level trough will exit the East Coast into the western Atlantic as a ridge builds over the High Plains. Surface high pressure centered over the lower MS Valley will lead to tranquil conditions for a large part of the area east of the Rockies. Models show a weak mid-level trough over southern CA. A few high-based showers and possibly a thunderstorm could develop over southern NV and perhaps the far southern Sierra Nevada. However, the thunderstorm risk appears too negligible to warrant an areal thunderstorm highlight at this time. ..Smith.. 10/31/2020
