This system will have the potential to bring a few strong to severe storms with all modes of severe weather possible, and the entire area will have the potential of seeing strong to severe storms. Residents should continue to monitor the forecast for updates as this threat evolves.

AVIATION

(18Z TAFS) Issued at 1155 AM CDT Tue Mar 10 2026

Most locations are currently at MVFR conditions with lower ceilings being the driver. These will fall through the night possibly reaching LIFR due to decreased visibilities. Overall, conditions overnight are expected to be much like last night. If lowered visibilities do occur, they will last through the mid morning hours before clearing to MVFR to VFR.

MARINE

Issued at 1155 AM CDT Tue Mar 10 2026

The low pressure to the west and high pressure to the east drive onshore flow through the timeframe of the frontal passage Wednesday night. Wind speeds will increase from teh current 5-10 kt to around 15 kt immediately preceeding the frontal passage. SCY conditions will quickly develop and we could even see a period of Gale conditions. Showers and thunderstorms will accompany the front as it moves through the coastal waters Wednesday evening into the overnight hours. These storms could also bring very strong localized marine winds and even a few waterspouts.
