Comments:
The storm system that moved through the area from November 30th to December 1st, was quite impressive to say the least. Most locations around the valley received over one inch of rain, with some areas receiving over four inches! Due to the impressive rain totals we have rated this storm in the significant category.

The large amount of rain was due mainly to a cut-off low which formed and stayed stationary for several days off the coast of Baja. As the cut-off sat over the Pacific, it was able to draw up a copious amount of subtropical moisture. As the low moved closer to the area, this moisture was pushed into the state. As the low itself moved through, it had very good dynamics to interact with the moisture allowing for a large area of light to moderate rain, with periods of heavy rain, to move through the valley. Click on the water vapor loop at the bottom of this page to view the evolution of this storm system from November 27th to December 2nd.

The rain at our location started around 11:30am on November 30th, with continuous light to moderate rain being recorded until 12:30am on December 1st. This portion of the storm gave us 2.03in. of rainfall. Another area of light showers moved through the area around 6:15am on December 1st, adding an additional 0.02in. to the total. During the day on December 1st, a shortwave trough moved through the area creating periods of showers and thunderstorms across the valley. During the day two storms moved through the area. The first occurred around 9:30am lasting until around 10:15am with a rain total of 0.08in., and the second more intense storm moved through the area from 1:00pm to 1:45, leading to an additional 0.32in. of rainfall. The overall storm total from November 30th to December 1st for our location was 2.45in.. This is the most rainfall we have recorded from one storm system since we started keeping records in April 2001.

Below you will find several radar loops along with a water vapor loop which shows the evolution of the storm. You will see the cut-low pressure system sitting off the coast of Baja, and then is will move up to the NE through the state, as a trough develops and moves down the west coast of the United States and then eventually into our area.
