Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0319 AM CST Fri Dec 12 2025 Valid 151200Z - 201200Z ...DISCUSSION... Strong high pressure will dominate the eastern CONUS on Monday with offshore flow across then entire Gulf Coast and East Coast. This dry, continental polar airmass across the eastern CONUS will result in no thunderstorms east of the Rockies on Monday and Tuesday. Some thunderstorms are possible along the coastal Pacific Northwest where some weak instability may be present. By the middle of next week, moisture return should resume across Texas. This may result in some thunderstorm activity by early Wednesday in the east Texas vicinity. Beyond Wednesday, model uncertainty increases substantially. However, severe potential will still remain too low as even the most favorable mid-long range guidance indicates minimal instability and low severe weather threat.
