National Weather Service Issues Warning About 'Unsettled Weather' in Major States Through May 5, From Snow Flurries to 90-Degree Temps

The National Weather Service is warning that "unsettled weather" is about to strike multiple states on Sunday, May 3, 2026, through Tuesday, May 5.

The inclement weather could hit parts of Florida, California, and other states. Weather cross the country will be volatile, with some areas receiving thunderstorms, others receiving snow flurries, and some facing soaring temperatures.

Southeastern Florida Can Expect 'Showers & Thunderstorms'

According to the National Weather Service, people in southeastern Florida can expect bad weather.

"Showers and thunderstorms near a stationary front could bring heavy rain across southeastern Florida later on Sunday," NWS wrote. "Unsettled weather will spread into northern California, the Great Basin, and the northern to central Rockies to start the new work week."

However, some areas could see warmer weather.

"Another night of frost/freeze expected over the east-central U.S. but unseasonable warmth for the Pacific Northwest followed by cold air intrusion for the northern U.S. on Monday," NWS wrote.

"A cold front sliding farther south into the Gulf and off the coast of southeastern U.S. will continue to spread organized showers and thunderstorms across the Florida Peninsula through tonight," the statement said. "Some of the thunderstorms could contain severe weather across the central portion of the Florida Peninsula Saturday afternoon into the evening. The front is forecast to slow down on Sunday and become nearly stationary by Sunday evening."

Floridians should expect some heavy rainfall.

"The showers and thunderstorms will begin to linger across southern Florida, and it is possible for southeastern Florida to receive some heavy rainfall from some of the slow-moving or back-building thunderstorms later on Sunday or Sunday night," the post added.

"Some showers are expected to linger into Monday for South Florida but drier air from the high pressure ridge moving off the East Coast should keep the showers relatively light on Monday."

Parts of New England Can Expected 'Isolated Snow Showers'

Even though it's May, some areas of the country aren't out of the woods when it comes to snow.

"As the aforementioned cold front moves off the East Coast tonight, a low-pressure system is forecast to rapidly intensify over the Gulf Stream and track just off the coast of New England on Sunday," NWS wrote.

"While the core of the system is expected to remain offshore, a round of rain is forecast for southeastern New England with gusty winds tonight, followed by eastern Maine during the day on Sunday," the statement added. "Isolated snow showers could brush the higher elevations of interior New England on Sunday before showers associated with a clipper system passing north of the Great Lakes move into the interior Northeast on Monday."

The Sierra Nevada & Great Basin Were Also Mentioned in the Forecast

Meanwhile, NWS wrote, "an upper-level trough off the West Coast is forecast to evolve into a cut-off low and become slow-moving as it becomes disconnected from the main jet stream. A frontal boundary will be slow to move through the Southwest for the remainder of the weekend into early next week."

Northern California, Sierra Nevada and into the Great Basin "will see unsettled weather spreading into the region through Monday. Meanwhile, cold air from central Canada is beginning to surge southward and is forecast to spread into the northern U.S. on Monday with falling temperatures and increasing chance of showers for the northern to central Rockies," the post added.

Temperatures are rising in some areas of the country.

"In the eastern half of the country, another night of frost/freeze is expected over the east-central U.S. before a quick warm-up into the 70's is forecast on Monday," the statement said. "In the Southeast, temperatures are anticipated to stay in the low to mid-60s, while the Great Lakes region should see highs recovering into the 50s on Sunday. Meanwhile, in the Northwest, temperatures will remain well above average."

Concluded the forecast: "Parts of Washington and Oregon could see highs approaching and potentially exceeding 90 degrees on Sunday. A cooldown is then set to begin for most of the West as the aforementioned upper low/trough moves inland, with the exception of the Pacific Northwest, which will remain unseasonably warm through early next week."
