This blog will be issued every Monday, Wednesday, and Saturday morning and updated if the weather is changing or critical or interesting weather events are occurring.
Clear skies and calm winds tonight will allow some areas in the north end of he valley to at or near freezing.
Over the next week the low pressure area in the Gulf of Alaska will continue to generate frontal systems and will also pull warm moist air northeastward to mix into them. However, at the same time a high pressure ridge will develop over the southwestern U.S. and will build northward. This will push the jetstream or storm track to our north and take most of the moisture with these systems to the north (see map below). This means just a few clouds and light precipitation as the storms move into the Pacific Northwest.
Clouds will increase Sunday as the first system approaches the Pacific Northwest. Sunday night and Monday the north state will be partly cloudy to cloudy with light rain or showers over the coastal mountains and areas north of Redding with scattered showers over the Sierra Cascades. Snow levels will be above 6000 feet. Tuesday there will still be a few showers over the north coast and near the Oregon border with partly cloudy skies elsewhere. Wednesday and Thursday we will see partly cloudy to cloudy skies with light showers over the areas west and north of the valley.
Friday through the weekend look partly to mostly sunny with above normal temperatures.
