WALLA WALLA — This lengthy dry spell may finally splatter to a halt this weekend.
Starting Friday, a significant shift in the weather is in store thanks to a weather system now approaching the Pacific Northwest.
The system will aid the break down of the high pressure that has provided warm and dry weather for weeks on end. As a result, rain is in the forecast starting Saturday through next week.
According to the National Weather Service, the system will bring gusty winds and wet weather into the region through next week. Rainfall amounts could vary from a tenth of an inch to a half-inch in heavier-hit areas.
Winds are also expected to begin picking up Friday with gusts up to 28 mph by Saturday.
Temperatures will cool several degrees as well, but will remain in the 60s and lower 70s during the day with mid-50s to mid-60s in the mountain areas. Nighttime lows should be fairly mild due to significant cloud cover each night.
Snow levels are expected to remain above 7,000 to 8,000 feet elevation through Monday evening.
The dry spell began on July 18 and stretched through this month. The only measurable precipitation during the period occurred on Aug. 21 when .01 inch fell during an early morning thunderstorm. Other than that, only trace amounts were recorded.
