What to Know About Next Week’s Weather Across the U.S.


Five Things You Need to About Next Week's Weather
  • Heat relief and storms are ahead for the Midwest, Northeast.
  • Scattered showers and thunderstorms will rumble across much of the South.
  • Monsoon activity will likely decrease later next week.
  • The Northwest will experience a stretch of hot temperatures.

A pattern change will bring notably different weather across much of the U.S. next week.

This pattern change will begin midweek when an upper-level ridge of high pressure shifts and builds into the West. In addition, a trough or southward dip in the jet stream will build over the Midwest and East.

Changes in temperature and precipitation are expected across much of the U.S. in response to the pattern shift. 

Tropical activity is not expected in the Atlantic, a break after Beryl and Chris.

Here’s closer look at what each region across the U.S. can expect in the week ahead.


Above-average temperatures and humid conditions will start the week across the Northeast. Highs in the upper 80s and 90s will be common and lows will only dip into the upper 60s and 70s.

A cold front will approach the region Monday and showers and thunderstorms are expected ahead of this system near the eastern Great Lakes. 

The front will continue pushing eastward Tuesday and will be off the Northeast Coast by late Wednesday. Showers and thunderstorms will accompany this cold front and a few strong to severe storms cannot be ruled out. 

Midweek Forecast

(Contour on the map is precipitation forecast for Tuesday.)

High pressure will build in behind this system and bring dry conditions. In addition, it will feel cooler as temperatures return to near average for late week and humidity levels drop.

Highs will generally range from the mid-70s to the mid-80s late next week and lows will drop into the 50s and 60s.


The week will start with warm temperatures and elevated humidity levels before a cold front moves through late Sunday through early Tuesday.

Scattered thunderstorms and a few severe storms are possible across the Great Lakes, Midwest and into parts of the northern and central Plains on Sunday and Monday.

Mid-to-late week another cold front will slide into the northern Plains and Upper Midwest while a system will also push into the mid-Mississippi and Ohio valleys. As a result, shower and thunderstorm activity will return beginning late Wednesday.

Temperatures will be near-to-below average for much of next week. Highs will be comfortable, especially for mid-July, generally in the 70s and lower 80s.

Lows will range from around 50 degrees near the Canadian border to the mid-to-upper 60s toward the mid-Mississippi Valley.


The notable pattern change later next week will result in an increase in precipitation across the Southeast. Before this shift, scattered afternoon and evening thunderstorms will develop each day across the region.

A frontal system will approach midweek and enhance shower and thunderstorm activity from the lower Mississippi Valley into the Southeast.

Temperatures will be near average. 

South Forecast

(Contour on the map is precipitation forecast for Tuesday.)

The southern Plains will remain generally dry and hot, with temperatures increasing later next week. 

Highs will be near-to-slightly-above average and will climb into the upper 90s to lower 100s.


A ridge of high pressure will bring above-average temperatures early next week to the Pacific Northwest. 

Onshore flow will likely keep temperatures along the coast cooler than locations farther inland. Highs in the upper 80s to lower 100s will be common into midweek.

The National Weather Service noted that Seattle could see a stretch of six consecutive days with highs of 85 degrees or higher, beginning late this week. There have been only four longer streaks in more than 120 years of records.

An upper-level trough will move into the Northwest late next week returning temperatures to near average for mid-July. 

Mainly dry conditions will also persist across the region, although a disturbance could bring a few showers to the Northwest late Sunday and again late next week.


Monsoon moisture will continue to bring showers and thunderstorms to the Southwest into at least midweek.

However, high pressure will shift during the second half of the week, which will affect where thunderstorms will develop.

Rainfall Forecast

(Locally higher rainfall amounts are possible.)

Moisture levels are expected to decrease later next week across much of New Mexico and Arizona resulting in less shower and thunderstorm activity across parts of the region.

As moisture decreases temperatures will increase here.

Isolated showers and thunderstorms will remain possible through late week, including in southern California and southern Nevada.
