Rain and thunderstorms disturbed Mother's Day across the eastern third of the United States, while the South Central states welcome much-needed drying and heat relief comes to the Pacific Northwest.

After enduring yet another day of flooding rain and severe thunderstorms, drier air will finally sweep across most of the South Central states on Sunday.

Some sunshine will give residents an opportunity to start storm cleanup and even celebrate moms with a picnic.

However, those living along rivers will still have to contend with rising water.

The same storm that brought the soaking and stormy start to the weekend in the South Central states will spell trouble farther east.

On Sunday, rain is expected to make for a chilly and dreary day across the mid-Atlantic and southern parts of New York and New England. Some rain and drizzle can also dampen the southern Great Lakes, including around Detroit.

Dry weather should hold on across northern New England on Mother's Day.

In the warmer air to the south, locally severe thunderstorms can endanger those outdoors from southern Virginia to the east-central Gulf Coast.

The better time for outdoor festivities along the southern Atlantic coast will be during the morning hours before thunderstorms erupt in the afternoon and evening.

A thunderstorm or two may also force anyone enjoying Mother's Day in Miami or at the attractions in Orlando to seek shelter for a time later Sunday. Thunderstorms, however, should avoid areas from Tampa to Naples.

A separate, weaker storm will drop into the Heartland with showers on Mother's Day. While showers with this feature are likely to be rather spotty, they can be locally robust with a drenching downpour, small hail, thunder and lightning.

In the West, a topsy-turvy weather pattern will continue.

A storm in the upper levels of the atmosphere will cause showers and locally gusty thunderstorms to erupt on Sunday afternoon over the mountains of California and across Arizona, New Mexico and neighboring parts of Colorado, western Texas and Utah.

People with outdoor plans in this swath should be prepared to take shelter. Those with hiking in mind should use extreme caution over the ridges, due to the risk of lightning strikes, and in the canyons, due to the potential for flash flooding.

Despite the unsettled conditions, there will be breaks of dry weather over the region which may allow some outdoor activities to take place.

SW Sunday May 11


No rain is expected in Downtown Los Angeles and San Diego, where typical mid-May temperatures are anticipated.

Some of the best weather for outdoor conditions across the nation will be in the Northwest.

An end to the heat wave will be an extra gift for moms along the Interstate-5 corridor, including in Seattle and Portland, Oregon. After temperatures soared well into the 80s and challenged records on Saturday, highs will be held to the 70s on Sunday.

Unusual early-season warmth will hold across the interior Northwest. Following the severe cold over parts of Montana this winter, the warmth is well-earned.

NW Sunday May 11


Those who attempt to cool off in area lakes and streams this weekend should use extreme caution as water temperatures are still very cold and pose a significant danger.

Even with the forecast of rain in some areas and ongoing flooding in others, all of us at AccuWeather wish you nothing but the best on this Mother's Day weekend.
