High pressure is still over the western U.S. Today we will see some afternoon cumulus over the mountains with the chance of an isolated thunderstorm along and east of the Sierra Cascade Crest. Temperatures will be couple of degrees cooler, which is still well above normal. Northwest to north winds will increase this afternoon. Thursday and Friday will be clear with temperatures a little hotter. Locally gusty north winds will occur Thursday with light winds Friday.
Saturday the high pressure area will begin to shift back to the west and this will allow temperatures to cool a few degrees. Sunday a low pressure area will be over the Pacific Northwest (see map below). This low will move southeastward into the Great Basin. The system doesn't have much moisture with it, but it will drop our temperatures to below normal Sunday and Monday. The big affect will be wind, with strong and gusty north winds Saturday night through Monday.
Tuesday through the end of next week high pressure will be along the coast. We will see more clear skies and normal or a few degrees above normal temperatures.
