A sharp blast of cold air is gripping the central and eastern U.S., bringing dangerous sub-freezing temperatures that could kill tender plants, harm early crops, and even damage unprotected outdoor plumbing.
The National Weather Service has issued Freeze Warnings and Frost Advisories across parts of the Midwest, Ohio Valley, Deep South and Mid-Atlantic. Here, expect overnight lows plunging into the mid-20s—putting gardens and agriculture at risk in what should be the heart of spring.
There will be several areas most at risk for freeze and frost on Wednesday morning. The first area includes eastern Illinois, southern Indiana and southern Ohio into most of Kentucky and western West Virginia. The next area is western Tennessee, northern Mississippi, the northern two-thirds of Alabama and northwestern Georgia. The third area stretches from south-central Pennsylvania, most of Maryland and the Delmarva Peninsula, into most of Virginia and northern North Carolina. In all three areas, morning low temperatures on Wednesday will generally range from 25 to 32 degrees.
This sudden cold snap is particularly dangerous because spring vegetation is not hardened against freezing temperatures. When the water inside plant cells turns to ice, it expands, rupturing cell walls and leaving plants withered and damaged. Delicate crops like peaches, tomatoes, and lettuce are especially vulnerable, while hardier varieties such as spinach, pansies, and some root vegetables may survive with minimal harm.
Gardeners and farmers should take immediate steps to protect their plants. Covering tender vegetation with blankets, tarps, or even a thick layer of mulch can help trap ground heat and prevent frost damage. Potted plants should be moved indoors if possible, and watering the soil before sunset can help retain warmth overnight. Homeowners should also take precautions for exposed outdoor plumbing, as pipes may freeze and burst in these harsh conditions.
For now, the message is clear: bundle up, cover your plants, and prepare for a few more nights of winter’s bite before warmer days return.
