1.    DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638



High pressure will dominate the region's weather today with mostly dry conditions.  Dense fog will be a problem this morning in some valley locations.  A strong storm system developing in the eastern Pacific Ocean will move closer to the Pacific Northwest during the day today and increase clouds over the area.  Precipitation should hold off until tonight with periods of snow and gusty winds developing overnight tonight and tomorrow.  Tomorrow will see a wintery mix of weather over the region.
