Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1258 AM CST Sun Mar 09 2025 Valid 111200Z - 121200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Tuesday. ...Synopsis... Generally low-amplitude westerly mid/upper flow will develop over the Plains and Southeast on Tuesday ahead of an upper shortwave trough moving across the Southwest to southern Rockies. At the surface, a prior cold frontal passage deep into the Gulf and high pressure centered over the eastern Gulf will result in a dry airmass persisting for much of the period. Southerly low-level flow will increase across the western Gulf into the southern Plains late in the forecast period, allowing for some very modest northward transport of shallow Gulf moisture into south/coastal TX. However, thunderstorms are not expected in this warm advection regime as considerable dry air will remain in mid and upper levels through early Wednesday morning. ..Leitman.. 03/09/2025
