Happy Thursday, Central Oregon!
An upper-level ridge has moved into Central Oregon and will remain over the region through Saturday, then will begin to flatten.
Overnight lows will range from the mid-teens to low 20s.
Friday's daytime highs will warm up a bit, into the high 40s to low 50s.
The ridge will eventually flatten enough that by late Saturday night and Sunday, a cold front will sweep across the region under a northwest flow.
This will favor the Cascades for precipitation, but not so much along the east slopes of the Cascades.
Snow levels will lower late Sunday and overnight, getting down to 3,000 feet.
As mentioned, the northwest flow will favor the Cascades. With precipitation and with lowering snow levels, there will be some snow accumulations to deal with Sunday night for travelers over the mountains.
A cold front will have shifted south and east by Monday, but we can expect mountain snow showers to continue through Monday night.
Snow levels will start off around 3,000 feet and drop to 500 feet by Wednesday night, with a 50-70% chance of snow leading up to Thanksgiving.
