Today marks day eight of the heat wave over much of California, but it really has been a whole month of well above-normal temperatures away from the beaches.
For many of the valleys of southern California, today marks the eighth-straight day of triple-digit heat. Triple digits are not that uncommon this time of year. What is uncommon is that it persists this long without some sort of break. This is despite our computer models that showed some break in the hot weather from last week for early this week. However, the high pressure area has dominated, and it does not look like it is going to give up much the rest of the week. There might be a little drop in the temperatures after tomorrow, perhaps not quite getting to 100 in some of the valleys Wednesday and Thursday, but it is likely to stay well above normal. If it is shy of 100, it will be only by a couple to a few degrees. If anything, it will warm up a bit again Friday and Saturday. The same can be said for the coastal valleys of Central California and the Central Valley. The high heat continues all week even if temperatures drop off a little at midweek. No real relief for anyone.
As I earlier said, this has been a month of heat for California. Below is a chart of the departure from normal of temperatures up through midnight last night. You will notice quite the difference from the immediate coast to interior areas.
All of my friends gripe factor is reaching a feverish pitch (no pun intended), and it looks like I will not be a very popular person this week either. Oh, the woes of being a weatherman.
A prolonged rain-free pattern is setting in.
By this time in 1998 there was twice as much rain that had occurred to date compared to 2015-2016.
Could an unusual El Nino precipitation pattern be as simple as looking at the state of water temperatures?
One thing that I find interesting is that the pattern since fall has not been your typical El Nino storm pattern.
There are signs of a possible stormier pattern beginning the week of Jan. 18.
The cumulative effect of the series of storms will mean flooding, mudslides and debris flows are going to be a problems for much of the week
