Opposing air masses affect America: scorching heat in the south and polar cold in the north.

Arab Weather - Meteorologists at the Arabia Weather Center indicated that the latest computer modeling outputs indicate that large areas of the United States, especially the south and west, will continue to be affected by the heat dome phenomenon. This phenomenon is accompanied by an air mass with high surface heating, resulting in extremely hot conditions, especially with the increased air heating caused by the Foehn effect. This is accompanied by the rush of polar air masses towards the north of the continent, causing rainstorms and snowfall.

Tropical high strengthens, fueling heat dome over North America (temperatures exceed mid-40s)

According to computer simulations, an upper wave is expected to cross northern North America, leading to the intensification of a tropical high south and east of the continent. This will fuel a heat dome phenomenon, bringing hot to extremely hot weather across various states, especially the southern ones. Daytime temperatures are expected to exceed the mid-forties Celsius in some areas, particularly in plains and low-lying areas.

The rising temperatures and warming of the air are further exacerbated by a climate phenomenon called the "Foehn wind," which will also play a significant role in the severity of the heatwave in the United States, particularly in the plains, slopes, and valleys east of the American mountain ranges.

This hot weather is also accompanied by unstable weather conditions, leading to heavy to very heavy rainfall in various regions, especially in the states bordering the Gulf of Mexico.

North America is affected by an extremely cold polar mass and winter storms.

In stark contrast, North America is being affected by a very cold polar air mass coming from the Arctic. Due to the presence of water bodies and the influence of lake phenomena, large atmospheric pressure differences form between the polar air mass and the warmer, more humid air, creating deep depressions and storms bringing strong winds, leading to a significant drop in temperatures and heavy rainfall in many regions. The Rocky Mountains in Canada and Alaska, as well as northern Canada, are also expected to experience heavy snowfall in the coming period.

And God knows best.
