Mother's Day forecast brings storms to South and triple-digit heat
Multiple rounds of rain and storms, some severe, will move through the South on Mother's Day, giving outdoor plans a weather problem from the start. The forecast also calls for scattered showers in the Northeast while the Interstate 95 corridor from Boston to Washington stays dry during the daytime hours.
For families trying to keep Mother’s Day plans outside, the shift comes quickly: the South faces the wettest stretch, while Las Vegas and Phoenix are set for triple-digit heat. The practical choice for the South is an indoor backup plan.
South on Mother's Day
The South is the main focus of the forecast, with multiple rounds of rain and storms expected and some of them severe. That puts the day’s busiest hours at risk for interruptions across a broad region, especially for anyone planning meals, travel, or gatherings outdoors.
The forecast does not point to one brief burst of rain. It shows repeated rounds, which can stretch the timing of impacts across the day and make a single outdoor window harder to count on.
Boston to Washington
Along the Interstate 95 corridor, daytime conditions from Boston to New York City, Philadelphia, and Washington look dry on Mother's Day. That gives much of the Northeast a clearer stretch for daytime plans, even as scattered showers remain possible elsewhere in the region.
The Northeast therefore sits in a narrower window than the South: dry for the daytime hours along the corridor, but not a uniform dry day everywhere. Travelers and anyone moving between cities still have to work within that split forecast.
Las Vegas and Phoenix
The West has the opposite problem. Highs are forecast to reach the triple digits in Las Vegas and Phoenix on Mother's Day, adding heat to a holiday already shaped by weather.
That leaves the country split three ways: storms in the South, scattered showers in parts of the Northeast, and extreme heat in the West. For anyone making plans, the best move is simple — keep the South indoors and use the dry corridor farther north only during the daytime hours.
