.SHORT TERM /Through Saturday Night/...

Issued 213 PM MDT WED MAY 6 2026

Warm, dry weather will continue the next several days due to a

nearly stationary ridge of high pressure aloft along the coast.

A faster-moving upper trough in the mid Pacific will weaken as

it moves eastward through the ridge and into our area Friday 

evening. A dry cold will pass through our CWA Friday afternoon. 

Thursday and Friday should be 2-4 degrees warmer than today. 

Daytime winds Thursday and Friday will be from the west or 

northwest 10-20 mph with afternoon gusts 25-30 mph (in the 

Snake Basin). Nighttime winds will be west or northwest 4 to 8 

mph, with enough mixing to keep low temperatures near normal.



&&



.LONG TERM /Sunday through Thursday/...

Issued 213 PM MDT WED MAY 6 2026

Slightly cooler temperatures on Saturday will give way to a 

prolonged period of hot and dry conditions as an upper ridge

builds over the western US. Temperatures will rise to 15 to 20 

degrees above normal by Sunday, with highs of 85 to 90 degrees 

in the Snake Basin and in southeast Oregon. This will bump 

HeatRisk levels into the minor category - primarily affecting 

those who are extremely sensitive to heat and without 

cooling/hydration.
