SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0146 PM CST Thu Jan 01 2026 Valid 012000Z - 021200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected through tonight. ...20Z Update... The potential for lighting flashes with low-topped convection across parts of southern CA has generally diminished, as a shortwave trough continues northeastward across northern/central CA this afternoon and evening. Cooling mid-level temperatures and modest daytime heating may still support sufficient MUCAPE for isolated thunderstorms across parts of central CA for a few more hours this afternoon, before this potential diminishes this evening. ..Gleason.. 01/01/2026 .PREV DISCUSSION... /ISSUED 1019 AM CST Thu Jan 01 2026/ ...California... A shortwave trough will continue to move inland along coastal north-central California early today, and toward the Sierra and other parts of Nevada late this afternoon into tonight. With minimal buoyancy noted in 12z observed soundings, convective potential will further diminish across far southern California coastal areas today via frontal passage. More immediately preceding the aforementioned shortwave trough, potential for a few low-topped thunderstorms will exist through the afternoon across the central Valley.
