Highs near 100 F (37 C) can be expected most days throughout.
Constant temperatures in that range are forecast for the South West, & a continuous heat wave up the Eastern Seaboard. /8
The South West has often born the brunt of U.S. heatwaves and this one is no exception. Only at night will temperatures fall briefly below 70 F and then only in the north. #HeatDome
In this forecast you can see that the heat wave moves north and digs in. Extreme temps can be expected till 23rd July at a minimum, assuming the Heat Dome forecast is accurate. /10 #HeatDome
