The heat wave is expanding into the Midwest and Northeast this week
- Hotter than average temperatures expand into the Midwest and Northeast this week.
- The Southwest will continue to be very sweaty.
- The expanding dome of high pressure is the cause of heat diffusion.
A record-breaking heat wave in the U.S. Southwest is spreading to parts of the Midwest and Northeast this week.
This persistent excessive heat has prevailed over the country’s southern layer, from the southwestern desert to Florida, for most of this month. It was the hottest start to July on record in Phoenix, Baton Rouge and Miami.
Now that the heat has spread toward the northern tier over the coming days, high temperatures will rise toward 100 degrees in some Midwestern cities and into the 90s in the Northeast.
Heat alerts are in effect for millions of people. The National Weather Service (NWS) has issued extreme heat advisories and heat advisories for the West and Plains. This means that outdoor activities should be limited in these areas now and in the coming days due to the potential for heat-related illness.
More heat advisories are likely to be issued over the next few days.
The heat is spreading to the Midwest and Northeast this week. After waiting for a lull in mid-July, a heatwave is on the way.
By Tuesday, high temperatures above 90 degrees will cover much of the Plains and Midwest. By Wednesday and Thursday, high temperatures could reach the upper 90s to near 100 degrees in the Plains from Kansas to as far north as the Twin Cities, and perhaps even Fargo, North Dakota.

The Northeast will also experience higher temperatures and humidity through the end of the week.
Highs will jump into the mid to upper 90s from New York City to Washington, D.C., for a while as the week comes to a close.
The heat index can peak near 100 degrees or more in the Northeast urban corridor as well as in parts of the Midwest.
Heat records in the Southwest continue to be broken. Even by the standards of the desert southwest, this heat wave broke records.
We’ve already seen all-time record highs in Reno, Nevada (108 degrees), and Grand Junction, Colorado (107 degrees). The temperature in Las Vegas, New Mexico, reached 100 degrees for the first time in records dating back to 1940.. The city’s airport is located at 6,867 feet above sea level, nearly 1,600 feet higher than Denver’s elevation.
In other cities, it is the longevity of the heat wave that has broken records.
In Phoenix, Sunday was the 24th straight day in which the temperature reached 110 degrees or higher, continuing the longest streak of its kind in the city’s weather records. They also had 14 straight days (through Sunday) in which their lows didn’t dip below 90 degrees, including The warmest low temperature on record was 97 Last Wednesday.

El Paso has surpassed its previous longest 100-degree streak since 1994 by more than 10 days, with its last day with a high below 100 degrees coming more than a month ago on June 15. Its highest level was 111 on Wednesday Last time in the summer they recorded a high of over 110 degrees And their hottest day in six years.
This potentially scorching heat will continue to impact the Southwest and Great Basin this week, including Albuquerque, New Mexico, Phoenix, and Salt Lake City.
Here’s how to stay safe: Hot conditions will be particularly dangerous for vulnerable groups, such as the sick and the elderly. The NWS has helpful thermal safety tips that can be incorporated into your daily routine when extreme heat sets in:
-Work sites: Stay hydrated and take breaks indoors as much as possible.
-Inside: Checking on the elderly, the sick, and those who do not have air conditioning.
-In vehicles: Never leave children or pets unattended – look before you close the door.
-in the fresh air: Limit stressful activities and find shade. Drink plenty of water and avoid alcohol.

That’s why we expect heat expansion: A strong high pressure area in the upper atmosphere is the main cause of this heat wave. Height causes air to fall toward the ground, compressing the air and making it warmer.
In this case, the heat dome will extend from the southwest to the plains during the next week.
This will spread extreme heat across the Plains, Midwest and Northeast while keeping areas from Texas to the Southwest hot.
