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.
This is some serious and dangerous heat. Outdoor activity is just not at all recommended during the daytime.
A strong ridge of high pressure in the West brings the highest heat of the season so far to a large area.
Combine the cold with the wind and some precipitation and there is a real danger of hypothermia.
Any shower and thunderstorm can contain heavy downpours, heavy enough to cause temporary, low-lying ponding.
According to all long-range models, the warmest area in North America compared to average will be over the Northwest.
No matter where you are, the sunshine gets more intense and causes quicker burning
