Hard Freeze Overnight, Stronger Midweek Storm, Warm Holiday Weekend Ahead

Overview

• Residents are urged to cover plants as a hard freeze settles in Monday night into Tuesday morning, with many spots dropping into the mid to high 20s and colder valleys near the teens.
• Temperatures rebound Tuesday afternoon into the 60s with some sun and a light breeze after the morning cold.
• Forecast guidance now shows a stronger system arriving late Wednesday on a slightly farther south track that increases the chance for a broad area of rain and high-elevation snow.
• Northeasterly winds aloft will push moist air up mountain slopes, favoring snow in the high country and rain in lower valleys, with 40% to 90% odds of at least a quarter inch from Rosebud County through Billings.
• After the midweek disturbance moves through, outlooks call for a dry, warmer Memorial Day weekend with highs in the 70s and 80s and plenty of sunshine.
