That was a lot of rain

The total rainfall from Wednesday night to Thursday morning was 41.8 mm, breaking down to 25.1 mm on Wednesday and 16.7 mm on Thursday.

As the rain occurred over two days it is hard to tell exactly how many times we have had this much precipitation in February.

For instance we had 28.1 mm on February 4th, 2006, but only 10.1 mm the day before. So although the one day total was higher in 2006 there was more from this storm in total.

What I do know is that the highest one day February precipitation total was in 2001 on the 9th when we had 49.9 mm, not surprisingly it was also a rain event.

Looking back at the records going back to 1970 I wasn't able to find any other consecutive days with over 40 mm of precipitation. Thus I'm confident in saying that this was the second biggest storm we have seen in the area during February since 1970.
