Advisories: NONE AT THIS TIME.
________________
For the rest of the week into the weekend another upper air trough of low pressure (“U” shape on yellow line) will be offshore pumping moisture our way, then it will start to move inland. A frontal system moved through, then a series of frontal systems like this one will keep at least a chance of precipitation around. Mountain snow levels have fallen well below pass levels, but there is not much of an immediate threat of serious snow in the passes.
