KEY MESSAGES

- Continued warm, dry, and breezy through Friday.

- Dry cold front Friday afternoon leading to slight cooling Saturday.

- Warming trend Sunday through Tuesday and staying hot and dry through the week.

SHORT TERM /Through Friday Night/

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 /Saturday through Wednesday/

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.
