June 28 rainfall

We got some significant precipitation in the area on June 28th.  At the UW weather station we recorded 43.8 mm during the day, the most intense part occurred between 2:15 and 2:45 pm when 16.8 mm came down.

This translates to what is referred to as a 1 in 2 year rainfall, that is not something that normally result in the numerous flooded streets and parking lots in the region.  Thus it is probable that a storm of this nature had areas of more intense rain that caused the localized flooding.

May 2013 Summary

A warm month with average precipitation

If you take a look at the graphs for this month, you can see that the temperature went back and forth between extended warm and cold spells.  As the warm spells lasted longer than the cold ones, it was 1.3 degrees hotter than average for the month overall.  This makes it the first warmer than average month since January.

Most of the precipitation for the month happened during just 3 days (the 10th, 28th and 29th).  This was enough to make it almost a perfectly average month (73.3 mm in May compared to the average of 75.7 mm).

Even with this average month, we are still about 100 mm over the precipitation we expect at this time of the year (340.2 mm compared to 448.3 mm).
