May 9, 2025 Friday Weather Update

Low pressure in Gulf similar impacts to tropical storm

What the month did

May 2025 was the 27th-warmest May in the 132-year national record (1895–2026), at 61.7°F against a 1991–2020 normal of 61.0°F (+0.7°F).

May 2025 was the 12th-wettest May in the 132-year national record (1895–2026), at 3.7in against a 1991–2020 normal of 3.1in (+0.6in).

NOAA/NCEI Climate at a Glance, contiguous United States. This is the observed record for the month, not a score of anything said in this piece — the forecast ledger begins 2026-08-17 and cannot reach earlier posts.

A sprawling area of low-pressure with embedded “tropical depression” like circulation will spin across the Gulf coast and Southeast for the next 5-days, at least.

Today, a surface low pressure (1002 mb) nears landfall in Southeast Louisiana. We’ll see if the convection organizes enough around the center of circulation perhaps to gain a TD designation.
