1/6/2015 7:00 AM 0.37 5.3 M 5.5 M No snow cores collected this morning, had no time. Snowfall totals and melted precipitation in the gauge
1/12/2015 7:00 AM 0.11 1.3 M 4.5 M Light snow accumulations. Still haven't had time to take core samplings. The snow pack warmed enough to allow some minor snow melt yesterday.
1/13/2015 7:00 AM T T M M M Very fine dusting of snow this morning. Getting chilly.
2/5/2015 7:00 AM 0.27 4.1 M 13.0 M Fast accumulating snow yesterday with a solid 3 hours of rates exceeding one inch per hour. Ended up with just over 4 inches.

2/9/2015 7:00 AM 0.00 0.0 M 2.5 M Significant snowmelt due to continued warm temperatures. Saw a period of locally dense fog as the warm air settled in over the snow pack. No precipitation to report during this time period.

3/25/2015 7:00 AM 0.32 M M M M Relatively decent rainfall during the late evening. It started much later than I anticipated. It did not begin to rain until about 11 PM. We had a few rumbles of thunder as well. I was very happy to hear thunder again!
3/26/2015 7:00 AM 0.00 M M M M It got nice and cloudy, but no rain came off of it. Reporting a zero for the day.
3/31/2015 7:00 AM 0.00 0.0 M M M No precipitation to report for the day. Looking forward to the warmer forecast!

5/9/2015 7:00 AM 0.88 M M M M I did not send in a report for yesterday (I was in a rush that morning). Combined 2-day total was 1.14" (0.88" over the last 24 hours, and 0.26" for the previous 24-hour period). I'm selecting minor flooding since the heaviest storms yesterday did result in brief, minor field flooding in the City of Pontiac, but no flooding was ongoing at observation time.
5/10/2015 7:00 AM 0.14 M M M M Occasional light rain showers occurred yesterday starting in the later afternoon and persisting through the night and even into early this morning.
5/11/2015 7:00 AM 0.44 M M M M Rain is falling at the 7 AM observation time. A nice steady rain at the moment. There has been several periods of heavy downpours that have occurred over the last 24 hours, but all were relatively brief.
5/30/2015 8:30 AM 1.26 M M M M Observation taken at 8:30 AM. Finally, we see more than an inch of rainfall for one event! I took one additional observation during this period: Between 7 AM and 10 AM yesterday, 0.37" of the total was accumulated at that time. The remainder came through the rest of that evening.
5/31/2015 7:00 AM 0.93 M M M M Another very rainy 24 hours. No flooding observed at observation time but there was some field flooding observed during a period of heavy rainfall just before 3 PM yesterday.
6/16/2015 7:00 AM 1.80 M M M M Rainfall totals. Minor flooding reported in typical flood prone areas of town, such as Timber Street, which was pooled with a few inches of water along its entire length.
6/17/2015 7:00 AM 0.50 M M M M Rainfall totals. Cloudy and rather chilly at observation time.
6/18/2015 7:00 AM 0.47 M M M M Apologies for the late send in.
6/19/2015 7:00 AM 1.37 M M M M Heavy thunderstorms came through during the afternoon hours yesterday, producing some of the highest rainfall rates I've seen in quite a long time. Nearly 1 inch of rain fell in about 15 minutes during the heaviest portion of the storm. Rather significant street flooding was observed after the storms passed through, but flooding has since subsided. There is no flooding ongoing now at observation time.
7/9/2015 7:00 AM 1.52 M M M M A light drizzle continues at the observation time. Significant rainfall amounts have occurred. Ponding of water on city streets is noted this morning. There was some rain yesterday morning followed by a few dry periods, before activity picked up again around 6 PM, lasting for several hours.
8/18/2015 7:00 AM 1.80 M M M M Rainfall totals over the past 24 hours. I can recall about 3-4 storm cells passing through the area during this observational period. The heaviest rain fell early this morning with some storms before 6 AM.
8/19/2015 7:00 AM 0.84 M M M M Two main rounds of thunderstorms occurred during the evening hours. 1st storm was tornadic. Tornado sirens in Pontiac sounded around 5:20 PM as there was heavy rotation coming into town. That storm brought some heavy rain and wind to the area. Another storm came through about an hour or so later. 2nd storm was not severe, but was more of an efficient rain producer than the 1st.
9/18/2015 7:00 AM 0.35 M M M M 24 hour rainfall total. Was woken up to some thunder and lightning early this morning.
9/29/2015 7:00 AM 0.00 0.0 M M M No precipitation to report for this observing period.
