3/2/2014 7:00 AM 0.07 M M M M Seems silly to try and measure depth as the wind moved the snow on in a lot of places. Seriously cold out.

3/12/2014 7:00 AM 0.01 M M M M I was conflicted about this entry. No ice made it into the gauge during the hit-and-run blizzard, so I melted what was frozen on the side, mostly out of curiosity since there was no visible accumulation by the time I got home, but very evidently moisture. It should count, right?
4/3/2014 7:00 AM 0.43 3.5 M M M The drainage behind my house is full and running fast.
4/14/2014 7:00 AM 0.41 M M M M I was gone over the weekend. This is the melted total of whatever fell Sat/Sun?mon
4/20/2014 7:00 AM 0.20 M M M M It rained for a very long time. I'm a little shocked this is all that accumulated in the gauge.
4/24/2014 6:00 AM 0.07 M M M M Nice rain, nice light show. But it froze again. Fruit tree blossoms look OK but there was full-on ice on the side of my gauge this AM
5/8/2014 6:00 AM 0.24 M M M M Somehow, after all the drama, I thought we would have more accumulation.
5/9/2014 6:00 AM 0.30 M M M M foggy today
5/11/2014 7:00 AM 0.78 M M M M still coming down hard here. City of Lafayette drainageway No. 2, behind my house, is full full full. Not yet into my back yard, but it's full.
5/12/2014 6:00 AM 1.07 3.0 M M M 7 a.m. - 1 p.m. 5/11= 0.52 in -- rain and snow 1 p.m. - 7 p.m. 5/11 =0.20 in -- rain 7 p.m. 5/11- 6 a.m. 5/12 = 0.35 -- snoq
5/17/2014 6:00 AM 0.10 M M M M a little foggy this AM
5/22/2014 6:00 AM 0.37 M M M M We were under T warn most of the day. It started raining HARD around 10 pm. Lots of T&L. At 3:08 a.m., the civil emergency sirens across the field from my house went off. Checked my phone -- no NWS notes, so went back to sleep because it was not raining, windy or T&L.

7/8/2014 6:00 AM 0.23 M M M M Sort of thought, based on all the fireworks, that there would be more rain. 0.13 fell in about 30 minutes time starting around 8:45 p.m.
7/14/2014 6:00 AM 0.14 M M M M
7/15/2014 5:30 AM 0.63 M M M M About 0.60 fell in a 15 minute period that started around 9:45 p.m. The rest fell in a brief, but heavy, storm just before 2 p.m.
7/16/2014 5:30 AM 0.10 M M M M for all the thunder, etc., it seems like there should have been more....

7/30/2014 5:15 AM 0.55 M M M M Measured 0.04 when I got home from work at 7 p.m. Tuesday. It started raining again around 10 p.m. Is still lightly raining at 5:27 a.m.
