The National Weather Service says warm, moist air from the jet stream could cause flooding in southwestern Oregon.
The Mail Tribune reported that meteorologist Charles Smith of the NWS Medford office says the weather system will cause about 1.3 inches of rain to fall over parts of Jackson County early Thursday through Friday night.
A weather service bulletin earlier this week reported near-saturated soils and low-altitude snow pack could cause streams and rivers to rise rapidly. It could cause flooding and high water levels in small streams and low-lying areas.
Up to 6 inches of snow is expected for parts of the Cascade range and around Crater Lake Wednesday night through Friday.
