The heat is going into the West as the East cools off the this weekend into next week. With the blocking pattern developing and a potential tropical system along the East coast, the heat will head into the West.
As you can see on the temperature map above, temperatures will be well into the 90s and low 100s all way into Washington and Idaho.
The Southwest and Central Valley will have highs up to 110 degree F. The heat will even impact coastal areas of California where highs will be in the 90s.
Seattle and Portland will have highs in the 80s.
Scattered thunderstorms will develop over the mountains during this time which will impact hikers and campers. Lightning strikes could cause some fires to break out which is another concern during this heatwave.
