northeastern Oregon Friday morning, before shifting into Idaho Friday evening.
That will maintain considerable shower activity with increasing northwesterly
winds ushering drier air, from west to east, across the region during the
afternoon and evening. Maximum temperatures will remain well below normal with
the snow level staying near 6000 feet. Cool air aloft will maintain good
daytime smoke dispersal conditions. A transitory and weak upper-level ridge is
forecast to bring mostly dry weather to northeastern Oregon Saturday and
Sunday. Clearing skies will make for chilly overnight periods with inversions
forming. Daytime smoke dispersal conditions will be fair to good with maximum
temperatures recovering close to normal by Sunday.<o:p></o:p></span></p>
