Weather reports on whatever I decide to report on.

Some drizzle was observed in the Tri-Cities area Thursday and Friday as a low pressure system worked its way through the region. That low is on its way east to bring some snow to the Plains and Canadian Prairies (with sharp temperature drops in places like Winnipeg). The Columbia Basin will be in between regional […]
