SPC 2000Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0140 PM CST Mon Nov 08 2021 Valid 082000Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the contiguous United States today. ...20Z Update... Based on recent short-term guidance, a small adjustment has been made to the southern extent of the general thunderstorm area across parts of northern/central CA. Occasional lightning flashes still appear possible later tonight into early Tuesday morning across this region, but weak elevated instability should keep the overall threat for lightning fairly isolated. ..Gleason.. 11/08/2021 .PREV DISCUSSION... /ISSUED 1028 AM CST Mon Nov 08 2021/ ...Northern California/southwest Oregon... Amplifying cyclonic westerlies will occur along the West Coast through tonight. Low-level moistening and destabilization, along with a late-period steepening of mid-level lapse rates, will support the possibility of isolated lightning flashes tonight in association with inland-spreading precipitation. A stronger or more organized/sustained thunderstorm or two might occur near the northern California and/or far southwest Oregon coasts late tonight, although severe storms are not expected.
