SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0744 PM CDT Mon Oct 18 2021 Valid 190100Z - 191200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for severe thunderstorms appears negligible across the U.S. tonight. ...01Z Outlook Update... Forcing for ascent and mid-level cooling, associated with a closed low migrating across the eastern Great Basin into the Wyoming and Colorado Rockies tonight, may continue to support destabilization marginally supportive of convection briefly capable of producing lightning. Isolated, brief weak thunderstorm development might also still be possible this evening across the mountains of southwest Texas, beneath difluent, cyclonic mid/upper flow. Otherwise, dry and/or stable conditions will generally prevail across much of the rest of the U.S., with negligible risk for thunderstorms. ..Kerr.. 10/19/2021 Read more LIVE:
