SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1042 AM CST Tue Jan 27 2026 Valid 281200Z - 291200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected Wednesday. ...Synopsis... A series of upper shortwave troughs within broader northwesterly flow aloft will move across the Southeast and from the Rockies into the Plains on Wednesday. Lee cyclogenesis is expected to develop over the central High Plains in response to the ejecting upper shortwave trough, with the low eventually migrating toward OK. Southerly flow will increase across the southern Plains in response, but surface high pressure over TX into the Southeast will prevent modified Gulf moisture from returning northward. As a result, a cold, dry, and stable airmass will remain over much of the CONUS, precluding thunderstorm activity. ..Leitman.. 01/27/2026
