Melissa’s Forecast Discussion:
The large trough of low pressure that brought in the arctic air for most of the western half of the U.S. is now starting to slide east. This cold air brought sub freezing temperatures for pretty much everyone above 4,000 feet west of the Rockies. Central Oregon dropped into the upper 20s Thursday morning while Eugene dropped into the upper 30s! (That’s about 13° below normal)
Along with the Cascades, the mountains outside Flagstaff Arizona got their first snow of the season. Winter Storm Warnings and Winter Weather Advisories are out for parts of Montana, Idaho, Nevada, Wyoming, Utah, Colorado and even New Mexico!
As that deep trough of low pressure moves on to the east, we’ll see the jet stream move back into southern Canada. This shift of the jet stream will warm us up about 10 degrees.
Friday is the transition day, which means we’re starting out with clouds and showers, but should finish with sun breaks and dry weather. Highs will still be on the cool side in the low 60s.
High pressure will return to the Pacific Northwest Saturday, which will clear out some of the clouds, dry us out and bring our temperatures up closer to average, in the mid to upper 60s. (perfect timing for the Beavs!)
This is all going to be short lived though! The next storm is lined up for Sunday. This one is on the weak side and will mainly stay to the north of us. I’m expecting showers Sunday morning, but dry for the afternoon. Temperatures shouldn’t be affected too much, so we should make it back into the mid 60s.
Another storm will roll in on Monday. This will bring showers Monday night and Tuesday.
Once we get through this second cold front, we’ll be in the clear Wednesday and Thursday. Highs should get back into the upper 60s
Have a great Weekend!
