West coast storm remnants bring rain and cooler temperatures by end of week

Weather

(WOWK) — As the “atmospheric river” that hit the west coast moves inland and weakens, the area of low pressure that once was a prolific rain maker will cross the Rockies in weakened fashion before generating back into a low pressure center that will bring chilly rain into our area toward the end of the week.

After Wednesday, the low is projected to reorganize into a low pressure center that will move over our region before being stalled by a blocking high pressure center to the north. The result will mean that the low meanders across our area Friday and Saturday before finally lifting away to the northeast on Sunday.

The result of the low stalling out here will mean plenty of rain late Thursday into Friday with lingering light showers on Saturday.

Temperatures will also run cooler than normal by several degrees thanks to the lingering low pressure, the clouds, northerly breeze and light showers on Saturday.

Very long range models also now finally show a push of much colder air making it into the region in about 10 days. The GFS model shows lows closing in on the freezing mark early Wednesday, November 3.
