An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) slides eastward to our northwest. Surface and upper level high pressure take over for while. Toward the weekend we see increased Zonal Airflow (west to east) across Oregon. The graphics for days 1-3 show a frontal system approaching from the north Friday. The graphics for Days 3-7 show a frontal system trying to push in from the northeast Sunday and another front from the north Tuesday, and still another frontal system coming from the northwest Thursday.
