Labor Day Weekend Forecast: Will Storms Impact Holiday Travel, Plans?

By Linda Lam
Published: September 1, 2014

Will your last unofficial weekend of summer be rained out by thunderstorms or will you be able to bask in the summer sun?

Moisture from the Gulf of Mexico will be tapped by a system moving across the South and East this Labor Day weekend. This system will bring thunderstorms and warm temperatures ahead of it to the eastern third of the country. Locally heavy rain and dangerous lightning may accompany some of these thunderstorms.

Another vigorous frontal system will shift out of the Rockies into the nation's mid-section, not only triggering severe thunderstorms ahead of it, but ushering in a cool, fall-like air mass behind it

Northeast

High temperatures generally will be warmer than average on Labor Day and it will be humid as well. Plans may have to be flexible as the risk for thunderstorms will continue. Some of these thunderstorms will have heavy downpours, frequent lightning and gusty winds.

South

Labor Day thunderstorms should be less numerous than on Sunday in most areas, except the corridor from Virginia to northern Florida and in Louisiana and the Upper Texas coast. Heat and humidity will be widespread, as highs will top out at least in the 90s in most areas. Record highs may fall again in parts of West Texas, where temperatures will soar into the 100s.

(FORECAST: Atlanta | Miami | Dallas)

Midwest

Thunderstorms shift farther east on Labor Day and it may be a soaker from the Great Lakes to the mid-Mississippi Valley ahead of a cold front. Some of these storms will be severe with large hail and damaging wind gusts. Muggy mid-upper 80s (and a few low 90s) are possible in the Ohio and mid-Mississippi Valleys ahead of the front, while 70s and a few 60s will be the rule behind the front in the Upper Midwest and northern Plains, where a few showers can't be ruled out.

(FORECAST: Chicago | St. Louis | Minneapolis)

West

Dry conditions will prevail throughout most of the West on Labor Day, with just a few thunderstorms in the northern and central Rockies. It will feel more like fall in the northern Rockies where high temperatures will be below average and a few flakes of snow are even possible in some of the higher elevations. Otherwise high temperatures will be near to above average.

97L Sweeps Toward Lesser Antilles; Nida Approaching Philippines

By Dr. Jeff Masters
July 30, 2016

A flash flood watch is in effect for Puerto Rico and the U.S. Virgin Islands as Invest 97L sweeps westward toward the Lesser Antilles. 97L will have an increasing chance of development as it moves toward the western Caribbean next week. Meanwhile, Invest 96L is struggling in the eastern Atlantic; Invest 91E could become Tropical Storm Howard in the Eastern Pacific over the next several days; and Tropical Storm Nida will sweep through the northern Philippines this weekend en route to a landfall in southeast China, perhaps near Hong Kong, early next week.

Hottest Reliably Measured Air Temperatures on Earth

By Christopher C. Burt
July 22, 2016

As Jeff Masters mentioned in his recent blog, a temperature of 54.0°C (129.2°F) was observed at Mitribah, Kuwait on July 21st. According to the Kuwait Meteorological Department this was the hottest temperature ever measured in the country (a reading of 54.4°C/129.9°F observed at the same site on July 16, 2010 has been disallowed as a result of a faulty sensor). The 54.0°C reading also is a new record for Asia and ties a similar reading at Death Valley (on June 30, 2013) as the hottest reliably measured temperature on Earth. The key word here is ‘reliably’. Many hotter temperatures have been reported from around the world in years past. However, all of these have credibility issues. In that vein I am going to revisit a blog I first posted on WU in October 2010 listing all the various claims to temperature readings at or above 54°C (129.2°F). In the years since I made that post I’ve learned more about some of these claims and have thus updated my entries and ‘validity’ scores as a result.

An extraordinary meteorological event; was one of its results a 1000-year flood?

The confluence of meteorological ingredients the first weekend in October 2015 resulted in an extraordinary weather event with severe impacts. Was one of them a 1000-year flood?

Why the Arrest of a Science-Loving 14-year-old Matters

By Shaun Tanner
September 16, 2015

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
