More than 230 million Americans will reach above-average temperatures before cold weather reaches most of the country

• Cities across the country are expected to experience above-average weather conditions due to the region’s upper level pattern
• Nearly 235 million Americans are expected to face temperatures 5 to 20 degrees above normal before the weather cools over the weekend.
• A strong El Niño will cause a dramatic change in winter weather conditions this year

The weather across the United States will make dramatic shifts this week, with cities from Arizona to New York expected to see above-average temperatures in the coming days before cold air brings back the feel of winter.

More than 235 million Americans will see temperatures 5 to 20 degrees above average for early November on Tuesday, FOX Weather reported.

This is a dramatic change from last week’s record snowfall in the Rockies, Great Lakes and New England.

According to the Weather Channel, the region’s upper-level pattern, which is when weather systems move parallel to latitude, will keep temperatures mild at the start of the week.

Warm weather will start in the southwest and spread east into Texas and the southern Plains.

These areas can expect to see highs in the mid to upper 80s, while the Mississippi and Tennessee valleys, as well as the Gulf Coast, will remain at around 80.

Cities in the South, such as Nashville and Chattanooga, Tennessee, and Huntsville, Alabama, could see record days with temperatures in the low 80s.

Cold winds are expected to blow from the west, bringing temperatures back to average by the end of the week.

St. Louis is expected to see a high of 83 degrees on Wednesday and a low of 61 degrees on Thursday, CNN meteorologist Allison Chinchar reported.

Denver is expected to see highs of 75 degrees on Tuesday and then reach a projected high of 48 degrees on Thursday with the possibility of snow.

Sudden temperature changes are common in Denver and the eastern slopes of the Rocky Mountains, according to AccuWeather.

Warm winds and dry conditions are expected to blow through Tuesday from the west and southwest.

By Wednesday into Thursday, winds in the Mile High City are expected to shift toward the east or northeast and the air will rise and cool causing temperatures to drop to 20-40 degrees within a few hours or less.

In Arizona, temperatures in Phoenix are expected to see above-normal conditions, remaining in the upper 80s and lower 90s through Wednesday, according to the National Weather Service.

“We expect fairly calm conditions, but (Monday) will be very hot and we will actually be very close to record high temperatures,” meteorologist Matthew Hirsch told the Arizona Republic.

The record set in Arizona on Nov. 6 is 94 degrees, which was set in 2007. According to Hirsch, there was a 50 percent chance of tying that record.

It’s a dramatic change from last week when snow fell on the ground in 17.9 percent of the contiguous United States, according to the National Oceanic and Atmospheric Administration.

The average temperature in the lower 48 states was 31.3 degrees, more than 10 degrees below average.

Cities across Texas, Oklahoma, Kansas and Missouri broke record lows. This included an 8-degree ice drop on Tennessee’s LeConte Mountain, the site’s first single-digit low on record.

The El Niño phenomenon is expected to hit the world hard this year, leading to a drastic change in weather conditions compared to average.

NOAA has published maps showing how much snow you can expect to fall on your state this winter based on average snowfall from past years — with record amounts of snow expected in the coming months.

During strong El Niño winters, more snow falls than average in the Midwestern United States and western states such as Colorado, New Mexico, Arizona, and Utah.

New England experiences much less snow than usual during severe El Niño seasons, and New York, Vermont and parts of Maine are likely to see much less snow this winter than the 1991-2020 average.

The El Niño phenomenon results from a change in the distribution of warm water in the Pacific Ocean around the equator.

This change in air and ocean currents around the equator can have a significant impact on weather patterns around the world by creating pressure anomalies in the atmosphere.
