National Weather Service Issues Warnings as Massive Cold Front Sweeps Across U.S.
A massive cold front is sweeping across the United States, affecting regions from Texas to New York. The National Weather Service (NWS) has issued frost advisories and freeze warnings for the Southern Plains, Midwest, Northeast, and Mid-Atlantic. Nighttime temperatures are expected to drop below freezing in some areas, posing a risk to early-season crops and sensitive vegetation. This cold surge is attributed to a polar vortex that occurred in March and April, creating conditions for cold air to move south from Canada. The coldest temperatures are expected in western and southern Wisconsin, with lows reaching 23 degrees. While some areas may not see temperatures fall below 32 degrees, frost remains a risk due to radiational cooling.
