Memorial Day outlook: Storms to threaten Great Lakes region

By Renee Duff • May 27, 2019 at 11:34 AM

As millions head outdoors for the unofficial start of summer, plans in the central and western United States could be jeopardized by stormy weather while heat persists in the Southeast.

The American Automobile Association (AAA) expects nearly 43 million Americans to travel by cars, trains and airplanes for the long holiday weekend, a 3.6 percent increase from last year and the second-highest travel volume since 2000 when record-keeping began.

 

In Norwalk, showers and thunderstorms are likely Saturday, mainly between 5 and 9 p.m. Otherwise it will be partly sunny, with a high near 86. There will be a southwest wind of 14 to 18 mph, with gusts as high as 30 mph, according to the National Weather Service.

On Sunday, showers and thunderstorms are likely, mainly after noon. It will be cloudy, with a high near 77. At night, there will be mostly cloudy skies and a 60-percent chance of showers and thunderstorms before midnight. The overnight low will be 56.

At this point, the forecast for Memorial Day in Norwalk looks good — partly sunny skies and a high near 75. The nighttime low will be around 63.

Tuesday will be warmer, with a high near 81 and a low of 66.Partly sunny, with a high near 81.

 

Central US to remain focal point of rain, thunderstorms

The nation's midsection will remain in the grips of a stormy weather pattern with rounds of rain and thunderstorms expected each day from today through Memorial Day.

There may be the risk of severe weather once again across the central and southern Plains, according to AccuWeather Senior Meteorologist Tom Kines.

While an outbreak on par with Monday is not anticipated, the severe storms can add insult to injury to areas still reeling from days of violent weather.

The morning and early afternoon hours may be the best times for outdoor activities before the bulk of the storms fire up late in the afternoon and evening.

The rounds of rain and storms can create new and/or worsening flooding problems across areas of the nation's midsection that have received above normal precipitation this month.

Northeast to endure occasional storms as record heat persists in South

An area of high pressure that will spur on a surge of heat in the Southeast later this week is forecast to remain firmly in place for Memorial Day.

This will result in mainly dry, sunny weather persisting for the holiday weekend, but there will also be a continuation of dangerous heat.

"It will feel like summer has already begun across much of the Southeast with record-challenging heat," Kines said.

Temperatures in the 90s to near 100 degrees Fahrenheit will be common with oppressive humidity levels pushing AccuWeather RealFeel Temperatures even higher.

The heat will make for great weather to hit local pools, lakes or streams, but it will make it necessary for anyone spending any length of time outdoors to drink plenty of water and wear light-colored, loose-fitting clothing.

The bubble of high pressure will protect the South from the storm systems originating over the Central states, instead directing them into the Great Lakes and Northeast.

"There will be the opportunity for showers and thunderstorms from the western Great Lakes to the Northeast," Kines said. However, he does not anticipate any one day of the holiday weekend to be a total washout.

Still, anyone attending ceremonies and cookouts or going camping and hiking will want to be wary of the threat for storms to pop up and produce dangerous lightning.

Cool, unsettled weather to persist in the West

A persistent dip in the jet stream will keep most of the West in an unusually cool, unsettled pattern into Memorial Day weekend.

"Memorial Day is the unofficial start to summer, but it will feel more like April from California to Arizona and Utah," according to AccuWeather Senior Meteorologist Kristina Pydynowski."

Showers and thunderstorms are likely to pop up each day of the extended weekend, mostly over interior locations but occasionally dampening coastal communities as well.
