A Freeze Warning has been issued for a large part of Iowa, with sub-freezing temperatures as low as 26°F expected early Thursday morning, October 23, 2025. The warning is in effect from midnight to 9:00 AM CDT Thursday. If you’re in the affected areas, now is the time to prepare for the cold and protect your sensitive vegetation and outdoor plumbing.
What to Expect:
- Low Temperatures: Overnight lows will dip into the upper 20s to near 30°F across much of the state. Widespread frost and a hard freeze are expected in many locations.
- Timing: The coldest period will occur between 2:00 AM and 9:00 AM CDT Thursday, when clear skies and light winds will allow temperatures to plummet.
Impacts:
- Vegetation: Frost and freeze conditions could damage or kill crops, flowers, and other tender plants. If you have a garden or recently planted vegetation, take steps to protect them before the freeze sets in.
- Outdoor Plumbing: Unprotected outdoor pipes, including hoses and irrigation systems, are at risk of freezing and could suffer damage. Drain or insulate outdoor plumbing to avoid potential issues.
How to Prepare:
- Cover Plants: Bring potted plants indoors and cover garden beds with blankets, sheets, or frost cloths to shield them from the cold.
- Insulate Pipes: Drain any hoses and outdoor faucets, and consider wrapping exposed pipes with insulating materials to prevent freezing.
- Stay Informed: Keep an eye on weather updates, and stay informed about the latest conditions in your area.
