December 2018 Weather Pattern Forecast For Southern California Released; Pending Major Pacific Storm RIPPER


It is that time again, the release of yet another month long forecast for the pattern across Southern California.  What does December hold?  Also am currently monitoring a powerful storm system for mid-next week, surrounding December 5th and 6th so read on for details …

Before I get into this.. There is a Winter Weather Advisory issued here for the Kern County Mountains for snow-wording on Saturday evening into Sunday …

The November forecast went extremely well.  Ended up with 1.6″ of rainfall in Downtown Los Angeles for the month, just over an inch from the last system Major Pacific Storm QUINTIN.  The average for Downtown Los Angeles is 1.25″ so we are now trending above average for October and November thus far.  Despite the rainfall, we ended up above average in temperatures, which was in the official November 2018 forecast here at Southern California Weather Force.  Now what about December?

Well .. December looks like it’ll have a number of storm systems hitting as well, with more powerful ones than November had.  We are now in a Moderate El Nino, trending evenly.  As stated in my forecast months ago… Moderate El Ninos tends to bring us better seasons and thus far this looks like it is maintaining.

The first December storm system will be the next name on the Southern California Weather Force 2018-2019 storm season list.  The next name after QUINTIN is RIPPER.  Major Pacific Storm Ripper is pending at the moment.  The system’s surface low on December 5th into the 6th (Wednesday and Thursday) is much further south than the last one.  This means that the storm itself will provide low level southeasterly flow in our metro areas.  Such a flow would bring the risk of severe weather, including thunderstorms, high winds, heavy rainfall, and even the risk of tornadoes.  These surface lows positioning just north or north-side of the Martin Storm Diamond is something that will need to be closely watched.  The rain model in the member section will be updated daily and today’s update is the main article image you see above.  More on that later…

There will be a break in Mid-December sometime between storm patterns before we get it elevated again around the mid-end of the month.  The Christmas time-frame may be stormy and feel a lot like Christmas this go around.

Overall the pattern is telling me we will have average to below normal temperatures region-wide for the month along with 2-4″ of rainfall.   The average for December is 2.49″ of rain and we should be above that mark by the time New Years Eve is over.

So.. with that being said.. stay tuned to Southern California Weather Force
