The ideas I put forth yesterday still hold for today. The stormy pattern remains from parts of northern California on north into Friday before charging south for the weekend throughout California.
I am going to show you a few charts today. The first two are the amount of rain or melted snow that accumulated in the 24-hour period in Washington and Oregon from yesterday morning to this morning.
As for additional precipitation, I will bring you what the GFS is showing for additional precipitation for the time periods listed.
From this morning through Friday morning:
From this morning through Sunday late afternoon:
I think the GFS is probably underforecasting rain amounts in south-central and southern California for the weekend. The European is locally heavier than the GFS but not everywhere. I still want to wait for more models to try to predict precipitation in the Southwest. However, what I had from yesterday for the Northwest is looking good.
More on these storms as the week progresses.
The remainder of the week a large building ridge of high pressure takes over
There will be more showers and thunderstorms are likely that can produce very heavy downpours in Arizona.
This rain caused problems with flash flooding producing some damage and there were a few swift water rescues.
Computer models are insistent that a rather strong piece of energy will move through California Tuesday, bringing more widespread rainfall.
This will make for a very hazardous period for firefighters into early Friday night.
