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.
Ref question for the comments...The wave length of the large scale features in the atmosphere is usually about the width of the U.S. Therefore many times when there is a strong high pressure ridge over the west there will be a trough or cooler weather in the east. In the summer the large scale flow shifts northward.
High pressure will continue to dominate our weather for at least the next week and probably longer. The high pressure ridge is currently building over the west coast. This will keep skies mostly clear and daytime temperatures will warm to 10 to 15 degrees above normal Tuesday through Thursday. The gusty north winds will continue through midday Tuesday.
The high will move back just off the coast Friday through the weekend as a low pressure area drops southeastward across Western Canada and the Pacific Northwest (see map below). The only affect this system will have on the north state is to cool temperatures to just a few degrees above normal and bring more gusty north winds into the area starting late Saturday and Sunday.
