Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0638 AM CST Sun Feb 23 2025 Valid 231300Z - 241200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are forecast across portions of Louisiana and immediate surrounding areas today. Additional isolated thunderstorms may occur in portions of Oregon/Washington. No severe weather is expected. ...Synopsis and Discussion... Satellite imagery shows a well-defined shortwave trough moving through the southern stream across TX. This shortwave is forecast to continue eastward throughout the day, progressing through the Lower MS Valley and ending the period over AL. Another shortwave trough will follow in the wake of the first wave. This second shortwave, which is currently over the central Rockies, is expected to continue quickly southeastward, reaching central TX by early tomorrow morning. Recent surface analysis places a low just off the Upper TX/southwest LA coast, with a cold front extending southwestward from this low through the northwest Gulf. This low is expected to move eastward ahead of its parent shortwave trough, remaining just offshore while gradually deepening. With this low expected to remain offshore, little if any airmass modification in anticipated onshore with offshore flow maintaining cool and stable surface conditions. Even so, moderate low-level warm-air advection (supported by 850 mb winds from 20 to 30 kt), will persist, supporting a broad area of mostly showers from the Lower MS Valley across the central Gulf Coast. Buoyancy will be limited by moist profiles and poor lapse rates, but cool mid-level temperatures should still support enough buoyancy for isolated to scattered thunderstorms throughout the day. Highest thunderstorm coverage is expected over LA Coast. Isolated thunderstorms are also possible across portions of OR and WA amid the strong westerly/southwesterly upper flow and cooling mid-level temperatures anticipated throughout the period. Greatest thunderstorm chances are expected after 00Z across WA, as a shortwave trough and associated large-scale forcing for ascent move through the region. ..Mosier/Grams.. 02/23/2025
