SPC 1730Z Day 2 Outlook Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1122 AM CST Sat Jan 20 2024 Valid 211200Z - 221200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the contiguous United States on Sunday or Sunday night. ...Synopsis... Broad mid-level troughing over the Desert Southwest and northern Mexico will feature a few weak perturbations moving through the base of the larger-scale trough. Farther east, a mid-level ridge will migrate east from the MS Valley to the East during the period as a trough departs the Northeast. In the low levels, surface high pressure over the OH Valley will become centered over the Mid-Atlantic states by early Monday morning. Southeasterly low-level return flow will strengthen Sunday night across TX commensurate with a warm-air advection regime. Showers will gradually become more prevalent Sunday night with a few elevated thunderstorms becoming increasingly possible. Weak instability will preclude a severe risk. ..Smith.. 01/20/2024 Read more View the full article

SPC 1630Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1023 AM CST Sat Jan 20 2024 Valid 201630Z - 211200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected across the CONUS today. ...Synopsis... Aloft, progressive and mostly zonal flow is expected to persist through the forecast period. A broad, low-amplitude shortwave trough over the East Coast will move offshore through the day, while a trailing shortwave ridge moves into the central CONUS. To the west, a Pacific trough will approach the coast of southern/central CA late tonight into early D2/Sunday. At the surface, a 1042 hPa high over the central Plains will migrate slowly eastward, reaching the mid MS Valley by the end of the forecast period. Associated with a continental polar air mass, sub-freezing, dry and stable conditions will suppress thunderstorm potential over much of the CONUS. An isolated lightning flash is possible across parts of coastal CA, but weak buoyancy, owing to poor mid-level lapse rates, and the late arrival of the upper-level forcing for ascent should keep chances well below 10% coverage thresholds. ..Lyons/Guyer.. 01/20/2024 Read more View the full article
