Severe Storms

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0635 PM CST Sun Jan 21 2024 Valid 220100Z - 221200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast tonight. ...01z Update... Changes are not warranted to the 20z outlook. Isolated thunderstorm threat continues tonight across portions of TX, southeast AZ, and along the CA Coast. The greatest risk for lightning is within a strong low-level warm advection regime over the southern Plains, primarily along the I35 corridor in TX. LLJ will increase across the southern Plains this evening, and increasing PW values atop cool/stable boundary layer will aid buoyancy for elevated convection across this region. Steep lapse rates across southeast AZ may yet allow a few updrafts to generate lightning across this region, but lightning has proven very sparse with this activity. Isolated flashes of lightning may also develop along the CA Coast later tonight in response to a short-wave trough that will approach this region after midnight. ..Darrow.. 01/22/2024 Read more

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0156 PM CST Sun Jan 21 2024 Valid 212000Z - 221200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast through tonight. ...Discussion... No change was made to the previous convective outlook. ..Smith.. 01/21/2024 .PREV DISCUSSION... /ISSUED 1029 AM CST Sun Jan 21 2024/ ...Discussion... Overall thunderstorm potential will be fairly limited/confined, with severe thunderstorms not expected across the CONUS. Expansive surface high pressure will prevail across the eastern half of the CONUS, along with an accompanying cold continental airmass. Low-level warm advection will expand across the southern Plains into tonight, with a northward transport of higher theta-e air. This will support elevated destabilization, and the development of showers and thunderstorms across parts of central and eastern Texas tonight. In the West, multiple low-amplitude disturbances will spread inland and across the West and Southwest deserts through tonight. Pacific moisture and weak instability will support a few thunderstorms, across southern Arizona vicinity today, and portions of coastal California tonight. Read more
