September 13, 2023 report

September 13, 2023

Summary  The weather pattern over the eastern Pacific and western US remains rather flat with no real dominating high or low pressure system. As a result, our weather will be typically dry with near average temperatures. By Sunday, a weak low center will approach the northern California coast, deepening the marine layer and allowing temperatures to slowly head south. An autumn style trough of low pressure will move out of the Gulf of Alaska, engulfing most of the western US by Tuesday for a refreshing stretch of weather well down into the 80s Monday through Thursday of next week. any precipitation this time of year will be well north with the possible exception of some light showers over the summit of the Sierra Nevada Tuesday through Thursday afternoon. By Thursday, a large high will be off the west coast and will begin to build inland, resulting in a warming trend weekend after next.    

Forecast Mostly clear skies through Saturday night. Mostly clear Sunday through Wednesday.

Two Week Outlook:  September 20  through September 26: This model is showing a broad area  of low pressure over and along the coast, resulting in below average temperatures. The chance for precipitation will remain extremely low.  

August:  This model indicates temperatures over the next 30 days will be near to slightly above seasonal averages. Dry weather will continue, although we will have to keep a watchful eye to the south for possible tropical activity. 

August, September, October: This model shows above average temperatures for much of the west, particularly the Desert Southwest. It also points to below average precipitation over the Desert Southwest, possibly meaning a less active monsoon season. The chance of precipitation for central California appears to be near average.

Wind Discussion:  Winds will be at or less than 15 mph through Saturday during the afternoons and evenings and generally at or less than 10 mph during the nights and mornings with periods of near calm conditions.
