A sudden drop in air pressure – not common for the Inland Northwest – could hit the region on Sunday. The National Weather Service is saying a crash of moist Pacific air and cold polar air could create high winds, rain and snow on Sunday – The Spokesman Review reports.
Called a “weather bomb” the clashing of warm and cold air could cause problems for the region.
Forecasters are mixed on just how the strong the winds will be – one forecaster said perhaps 45 to 50 mph but the other forecasters did not agree with them. They all agreed, however, that Sunday’s storm will mean snow in the lower elevations just before cold polar air hits and brings sub-freezing temperatures.
