Warm weather is expected to develop across most of the eastern US this week thanks to an unseasonable pattern change that will likely lead to above-average temperatures, with daytime highs getting into the 70s and 80s, for more than 200 million Americans.

As the jet stream reconfigures itself early this week, a dome of high pressure is expected to develop across the central and eastern US.

That will allow for the much warmer air to infiltrate areas of the Rockies, leading to what could be a taste of summer-like warmth.

According to the FOX Forecast Center, record-high temperatures will be broken across the country this week, particularly across the Southwest and the Rockies on Tuesday.

Temperatures could also climb into the 80s as far north as southern New England this week, with 70s likely into northern New England.

Dozens of record-high temperatures will risk being shattered in the Northeast this week.

As a result, the West will cool down again, especially the Pacific Northwest, where NOAA’s Climate Prediction Center forecasts the highest likelihood of below-average temperatures this week.

The spring warmup is important as some are still recovering after weeks of relentless severe weather.

The weather pattern change also means those regions where snow-fatigue has officially set in will get a much-deserved break from the relentless snow.

Most places from the West to the northern Plains, Upper Midwest and northern Great Lakes are predicted to see little to no snow into at least early this week.

This dry pattern could increase the risk of wildfires in some areas, particularly in parts of the South where drought conditions are present.
