When will the heat wave be over in US? Forecast and dates to know when it’s going to end

Large swaths of the US have been wilting under excessive heat over the past week. Relief is coming, at least to those in the Northeast, but first severe storms will pass over the area.

Meanwhile, the forecast for the Southern Plains and Lower Mississippi will continue to swelter with some place topping 100 degrees. At the same time the Northwest is bracing for triple-digit temperatures penetrating into the Columbia River Basin and Columbia River Gorge.

Heatwave outlook for Northeast

The extreme heat that has been stifling the Northeast for the better part of the past week will be on its last legs Monday. A cold front is moving over the area that will bring relief to those living in the Mid-Atlantic up to southern New England.

However, first a batch of severe weather, with damaging straight-line winds the most prominent threat, will decend on the Northeast through Monday early evening in some parts. But in its wake the temps will drop into the high 70s and low 80s which will feel a blessing after the highs experienced. Newark recorded five straight days over 100 degrees, the longest streak since records began in 1931, but that record is being contested as wrong.

Northwest will begin to bake

A strengthening upper level ridge over the northeast Pacific and western Canada will send the mercury rising from northern California up to the border with Canada through the week. Temperatures are expected to climb into the triple digits early in the week in the Columbia River Basin and Columbia River Gorge. Unfortunately, nighttime won’t bring much relief with lows hovering around 70 degrees.

Late in the week the thermometer could top 110 degrees in some locations and will remain high through the weekend. Early August could bring respite with temperatures dropping below average for much of the Northwest as the pocket of hot air moves over the Northern Plains.

The Southern Plains and the Lower Mississippi still scorching

Those living in the Central and Southern Plains and the Lower Mississippi Valley will continue to swelter under extreme heat with Heat Advisories and Excessive Hear Warnings in place across Arkansas, Louisiana, Missouri, Oklahoma, Tennessee and Texas.

Temperatures should be knocked out of the triple digits in Arkansas, Missouri and Oklahoma by the end of the week. However, although slightly lower, will be little changed for most of Texas and Louisiana.
