A wildfire outbreak in western and central Nebraska has burned more than 243 000 ha (600 000 acres) since March 12, 2026, according to state officials, including the Morrill Fire, which Gov. Jim Pillen described as the largest wildfire in Nebraska history.

The fires have also burned parts of Crescent Lake National Wildlife Refuge within the Sandhills, a region regarded as the world’s most intact temperate grassland.
A Moderate Risk (Level 4 of 5) for severe thunderstorms has been issued across parts of the Mid-Atlantic United States for Monday, March 16, 2026, as a powerful multi-hazard storm threatens over 100 million people across the U.S. Fast-moving storms capable of producing damaging winds and a few strong tornadoes are forecast to develop from the Carolinas into Virginia and Maryland during the afternoon and evening hours. A Moderate Risk is an unusually high severe weather category for the Mid-Atlantic and is not issued often for this region. The National Weather Service office serving the Washington, D.C. area described the setup as a “quite rare Day 2 Moderate Risk area” ahead of the event.
Heavy snowfall caused multiple vehicle spinouts and crashes on I-90 at Snoqualmie Pass in Washington, forcing authorities to close the highway in both directions on March 13 and keep it closed overnight into March 14, 2026.

A major winter storm is affecting the Northern Plains and the western Great Lakes in the United States on March 15–16, bringing heavy snowfall, strong winds, and widespread blizzard conditions. Snowfall rates of up to 7.5 cm (3 inches) per hour and wind gusts of up to 95 km/h (60 mph) are forecast across parts of eastern South Dakota, Wisconsin, and Michigan as a strengthening low-pressure system moves toward southeastern Canada. Travel conditions are expected to become extremely dangerous across the affected region.
Strong winds and very dry air behind a powerful storm system are creating critical fire weather across parts of Texas, New Mexico, Oklahoma, and Colorado on March 15, 2026, prompting Red Flag Warnings across multiple forecast areas. Wind gusts may reach 105 km/h (65 mph), while relative humidity is forecast to fall as low as 6 to 15 percent in some areas, supporting rapid fire growth and spread.
Freeze Warnings and Watches have been issued for parts of eight southern U.S. states as sub-freezing temperatures are forecast from March 16 into March 17, 2026. Temperatures could fall as low as −12°C (10°F) in the coldest parts of Arkansas, while many other areas are expected to bottom out in the −7°C to −2°C (19 to 28°F) range. Frost, freeze conditions, and gusty post-frontal winds may damage sensitive vegetation and, in the coldest areas, affect exposed outdoor plumbing.
