Halloween weather outlook: Storms may prowl central US as rain is likely to chill the Northwest

This year's traditional, door-to-door masquerade across the United States may be taken up in wet weather from the southern Plains to the Great Lakes and in parts of the Northwest.

There will be some safety concerns in the two wet weather zones, mostly due to poor visibility, but also the potential for locally robust thunderstorms in the middle of the nation.

Elsewhere, any haunts will likely be done by the creepy critters and not the weather.

Series of storms to continue in the Northwest

While the storm train in the Northwest will be far from earth-shattering and in some cases beneficial in terms of drought easement and stirring out pollutants, the timing of the storms may be such to put a damper on Halloween this year.

Parents of the little ghosts and goblins may want to toss a plastic rain poncho over the kids' outfits in the Northwest, including in Deadwood, Oregon, during Wednesday evening.

In this area, a modest storm is forecast to roll inland from the Pacific Ocean with rain focused in coastal Washington and Oregon. However, rainy conditions are also in store for northern Idaho, western Montana and the northeastern parts of Washington and Oregon.

Patchy fog may accompany the rain in the higher elevations of the Northwest.

Showers, thunderstorms to slice through middle of the nation

Farther east, showers and thunderstorms are forecast to progress eastward along a 1,300-mile-long stretch from eastern Texas to southern New York and a portion of New England.

The thunderstorms that may accompany the rain in some areas may do more than just add to a spooky feel for the evening in Spider, Louisiana.

Parents may want to keep up-to-date on the forecast in the south-central zone as there is a chance of a few of the storms becoming severe from eastern Texas to Louisiana.

Lightning flashes may be accompanied by high wind gusts and flooding downpours in such a case.

Even in the absence of severe thunderstorms, the rain may be heavy enough to cause flooding and/or washout trick-or-treating along a swath of the Tennessee or Ohio valley.

Dry conditions likely for East, northern Plains and Southwest

The weather is forecast to cooperate with trick-or-treating, fall festivals and for those traveling to masquerade parties on Halloween in the Southeast, mid-Atlantic, northern Plains and Southwest states.

A warm coat may be needed or at least a few layers of clothes beneath the costume in Spirit, Wisconsin, and in Devils Lake, North Dakota, due to the chill that will hold AccuWeather RealFeel® Temperatures in the 30s.

Seasonable temperatures are likely in Shadow Hills, California, with temperatures starting off the evening in the lower 70s. A creepy breeze may stir in Tombstone, Arizona, during the evening hours.

Characters in the Northeast may be able to get by with a light jacket.

A mild night is possible from the northern Gulf coast to the mid-Atlantic. Temperatures are likely to fall slowly through the 50s in Seven Devils, North Carolina, and may hover in the 60s in Scary, West Virginia.

Short sleeves should be just fine in Deadman Landing, Florida, where temperatures will start in the upper 70s to near 80.
