March 14, 2025 Severe Weather Outbreak

Two day severe weather outbreak from Midwest into Southeast

What the month did

March 2025 was the 7th-warmest March in the 132-year national record (1895–2026), at 46.8°F against a 1991–2020 normal of 43.6°F (+3.3°F).

March 2025 was the 57th-driest March in the 132-year national record (1895–2026), at 2.4in against a 1991–2020 normal of 2.5in (-0.1in).

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.

Quick update to show current weather models for the major storm system and its 2 regional severe weather outbreaks. Later this evening into early Saturday, storms will fire over Missouri and radiate NE into the Great Lakes.

A sharp trough at mid-levels is co-located with a surface low with pressure down to 975 mb over the central Plains by Friday evening. This is very low for an overland cyclone. At the base of the [cold-core] trough, an intense mid-level (500 mb) jet stream over 110-knots will aid in the explosive development of thunderstorms and provide significant wind and shear for potential of rotating supercells embedded with Quasi Linear Convective System (QLCS) racing ahead of the low tracking into Minnesota.
