Severe Storms

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0630 PM CST Mon Jan 22 2024 Valid 230100Z - 231200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected. ...01z Update... Several southern-stream short-wave troughs will influence convective potential from coastal CA into the lower MS Valley tonight. One weak short wave is ejecting across OK/east TX early this evening while a secondary disturbance is advancing across northern Mexico. Isolated thunderstorms have developed along the southern influence of the lead feature along the upper TX Coast where modified Gulf air mass has returned. Additional convection is now developing across northern Mexico, south of the Big Bend, within the left exit region of an approaching midlevel speed max. While the primary LLJ will shift into the lower OH Valley with the lead trough, southerly 850mb flow is expected to persist across TX tonight. Additional elevated convection is expected to develop in response to the northern Mexico feature as it approaches southwest TX later tonight. The boundary layer will likely remain a bit too cool along the TX Coast to warrant much potential for surface-based storms, thus the severe risk appears minimal. Upstream, isolated thunderstorms have developed across portions of CA, in a regime of steepening lapse rates ahead of a short wave trough. Convective threat will spread southeast tonight as the short wave digs into northwestern Mexico and the lower CO River Valley. ..Darrow.. 01/23/2024 Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0354 PM CST Mon Jan 22 2024 Valid 241200Z - 301200Z Fire concerns will be limited for the extended forecast period. Fuels are wet across the CONUS and additional wetting rain is expected for much of the CONUS this week. The only dry regions will be the northern Rockies/northern Plains where extensive snowcover is present with below freezing temperatures. ..Bentley.. 01/22/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0154 PM CST Mon Jan 22 2024 Valid 222000Z - 231200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected. ...20Z Update... Minor changes have been made to the general thunderstorm area, but otherwise the previous outlook reasoning remains valid. See the previous discussion below for more details. A few stronger storms are possible this afternoon/evening near the upper TX coast, and perhaps late tonight near the Edwards Plateau region, but the severe threat still appears limited through the end of the period. ..Dean.. 01/22/2024 .PREV DISCUSSION... /ISSUED 1036 AM CST Mon Jan 22 2024/ ...South-central CONUS including coastal Texas... Surface high pressure and cold stable conditions will exist over the eastern half of the CONUS, but multiple low-amplitude mid-level disturbances and a prevalent warm conveyor over the south-central CONUS toward the Ozarks/Midwest will influence widespread showers across that same region with continued elevated thunderstorm potential especially across east/southeast Texas toward Louisiana and the ArkLaTex. Weak surface-based destabilization should gradually occur near the upper Texas coast, beginning this afternoon and more so tonight. Within a favorable kinematic environment, a few stronger near-surface-based storms could occur as early as this afternoon across the upper Texas coast, but the overall severe thunderstorm potential is still expected to remain low through tonight. ...Western States... Showers and occasional lightning flashes will be possible from portions of southwest Oregon and California into southern Arizona. This convection will be associated with a pronounced mid-level trough embedded within broader cyclonic flow, with steepening lapse rates. Read more
