High pressure is still over the west and off the west coast. However, this morning's satellite picture (below) shows a weak low pressure trough dropping southward along the Canadian coast. This weak trough will remain over western Canada and the Pacific Northwest through the weekend. (see map below) The southern end of the system will sag southward along the coast. The main affect this system will have on our weather is to cool temperatures back to near normal and few clouds over the coastal and northern mountains Thursday and Friday. Light to moderate south to southwest winds will occur this afternoon and Wednesday afternoon with gusty north winds Wednesday night and Thursday.
The extended forecast maps show a strong high pressure ridge along the west coast through mid September. Sunny ...dry....above normal temperatures.
