Hail Storm

November 10, 2003, about 2:07 PM.
It did not hail everywhere in Livermore, as evidenced by the fact that there was a rainbow at this time also.
The hail was slightly larger than pea sized. As you can see there was quite a lot of it.
This photo was taken north of Concannon, east of Isabel, near Max Baer Park..

Notes:

Data is updated weekly, generally on Sunday Evening. It is often not updated when there has been no rain.
Monthly Totals and Monthly Compare will be filled in once the month begins, and will be partial data during the month.
Yearly Totals and Yearly Compare will always be listed for every month even before the month begins. This provides useful information, such as "where are we with respect for the entire year rainfall wise", or "where will we be at the end of next month if it doesn't rain any more until then".
Averages are calculated by averaging data from 1870 to present, and are adjusted each year. The averages listed do NOT include the current rainfall year. The 2013-2014 table average includes the data up through the 2012-2013 rainfall year, etc.
