SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0112 AM CST Sun Jan 18 2026 Valid 201200Z - 211200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Tuesday. ...Synopsis... A shortwave embedded within broader-scale upper troughing will move southeast across the Rockies into the Plains on Tuesday. As this occurs, lee cyclogenesis is expected over the central High Plains. This low will develop south/southeast into TX overnight and ensuing low-level south/southeasterly winds will transport modest Gulf moisture northward into portions of south TX late in the period. Forecast soundings suggest moisture will be relatively shallow and warmer midlevel temperatures will limit instability. While some warm advection showers could occur over TX Tuesday night into early Wednesday ahead of an southeastward advancing cold front, thunderstorm potential appears low. ..Leitman.. 01/18/2026
