Dangerous fever spreading from central US to northeast
The dangerous heat continues from the Great Lakes to the Gulf Coast, with hot advisories and extreme heat warnings from millions.

- Many in the US can feel like New York, Philadelphia and Washington are over 100 degrees, but much in the US is under extreme heat warnings and recommendations.
- Heavy rain, flash floods and harsh weather could be July 24th from the Central Plain, from the Midwest to the Great Lakes.
ARLINGTON, Va. – The relentless heatwave expanding eastward through the Midwest on July 24th, with temperatures approaching 100 degrees in New York, Philadelphia and Washington, DC promised by July 25th.
Over 130 million Americans had already received heat warnings, surveillance or consultation early on July 24th under a “heat dome,” which mixes high-heat and humidity cocktails and pushes heat indexes above 100 degrees in many regions. Thermal index measures how it actually feels when considering humidity.
“The heat wave in late July will continue to expand east later in the week, in a humid condition from the lower Mississippi Valley to the Midwest to the northeast and the Middle Atlantic,” writes Peter Marinax, a meteorological future meteorologist with the National Weather Service.
Mullinax said record high temperatures in parts of the northeast are likely to be “challenged” over the next two days, and that all affected areas are likely to have broken record lows.
Mulinax said on July 24th, the 100-105 thermal index will appear somewhere between 100-105 from the Southern Plains, the Midwest and the Great Lakes on July 24th. A local thermal index could probably approach 110.

head Torrential rains, flash floods and bad weather could be July 24th from the Central Plain to the Midwest to the Great Lakes.
“While west had ‘relatively quiet’ weather forecast, fire weather threats were effective due to lightning in parts of Northern California, Nevada, Utah, Oregon, Idaho and Wyoming.
The sheriff and emergency management coordinators of Carr County, Texas, were both asleep when a fatal flash flood overwhelmed the Guadalupe River in a sudden hour on July 4th. Leesa asked if he knew if coordinator William “Dub” Thomas was working at the time, and told CNN, “I’m sure he’s asleep at the time,” adding that he was asleep too.
Thomas is also a deputy sheriff under Leesa and did not immediately respond to requests for comment from USA Today.
The National Weather Service has begun issuing a July 3 warning that the storm could cause “severe flashes and city flash floods.” On July 4th, at 1:14am, weather services upgraded the clock to flash flood warnings, and an alert using the term “disaster” was used at 3:08am.
A flash flood emergency was declared at 4:23am. Thirty minutes later, reports of rooftop rescue began.
Leesa said the county emergency business center was not operating between 1am and 3am, causing the worst flooding.
The stubborn high-pressure systems fuel heat domes in the Midwest, but the low-pressure systems in the northeastern Gulf mean much of Florida, with parts of the northern Gulf potentially receiving even more heavy rain on July 24th.
In its July 24 recommendation, the National Hurricane Centre said the low-pressure areas “currently produce a wide area of disturbed showers and thunderstorms.” Forecasters said the system is expected to move generally west across the north-central and north-eastern parts of the bay for the next day or two days when some slow development is possible. By the end of the weekend, the system is expected to move inland and end its development potential.

According to William Galls, a professor of meteorology in the Department of Geology and Atmospheric Sciences at Iowa State University, heat domes are generated when permanent areas of high pressure trap heat in the area.
“Heat Domes can extend to several states and remain for days to weeks. People, crops and animals leave to suffer from a stagnant hot air that feels like an oven,” Gallaus said in a conversation article. Click here for details.

The heat dome does not dissipate immediately. The weather department says dangerous heat is expected in parts of the central and southeastern areas. Accuweather said high temperatures reach the west and west almost every day when they reach 100 degrees from Texas to West Tennessee.
The northeastern area was given several days: highs and relatively low humidity in the 80s. However, the dome spread throughout the region on July 25th, driving high temperatures deep into the 90s.
