San Jose CA Long Range Forecast 2018-2019
I firmly believe that from San Jose CA south we will see a drier and warmer than normal Winter/Spring as Fall will be warmer and drier than normal. My theory is if summer has been warm and with the major wildfires CA has had and with predictions of more fires for the Fall the warming from the fires and particles could lead to a higher chance of a drought.
I think that CA from San Jose south may be in for another long stretch of dry weather despite the El Nino forecast. The resilant ridge of High Pressure that was in effect during our last multi-year drought and the lack of sunspots may constitute for the Old Farmers Almanac to rethink their Long Range Forecast.
If we have a lot fo sunspots during an El NIno/La Nina Year think 1998 more flooding will occur due to the Pineapple Express.
Do you predecct above normal percipitation in the form of major Pineapple Expresses with mudslides along Highway 1?
Will San Jose CA be in for a drier than normal winter/spring for 2018-2019?

This summer
What are we looking at for late July to early August? Do you anticipate very hot temps in San Jose (90s or higher) or will it be more reasonable - or can we just not predict that very accurately yet?
