Time and Day: 1045 Monday

The Snapshot:  Intermittent rain showers today changing to light snow tonight.  Dry tomorrow and Wednesday, with snow Thursday night. 

The Science:  This morning’s radar has the first of several weak bands of moisture moving into the mountains.  A cold front approaching from the northwest will produce cooler temperature with continued light precipitation tonight.   The precipitation will taper off in the wake of the cold front early tomorrow morning with Tuesday and Wednesday trending dry and clear.

4-7day Long Range:  A cold front on Thursday will provide a good chance of measurable snow for Friday morning.  High pressure (I am getting sick of those two words) will once again, produce dry and clear weather for the PNW over the weekend.

Precipitation: Water by 4am = .25  Snow equivalent = 0-2   Total inches of water by noon tomorrow = .25 Total inches of snow by noon tomorrow = 1-3   Trends and Timing: Light intermittent rain showers changing to light snow is expected through the next 24 hrs.  Tomorrow trends dry.
