Observation Date Observation Time Precipitation Snowfall Snowfall SWE Snow Depth Snow SWE Notes
10/1/2015 7:00 AM 0.07 M M M M All morning long there was a very light rain mist coming down. At one point about 1115 it was still a mist but heavier for about 5 minutes. By the early afternoon rain had stopped although the sky remained cloudy. At one point, about 1400, the sun came through and it was quite warm for about 15-20 minutes. Some time during the night, 0050-0055 per my WS-2318 rain gauge, it rained 0.01". Perhaps it was a bit more due to the amount of water on my backyard deck.
10/2/2015 7:15 AM 0.26 M M M M A very light rain began at 0720 yesterday and continued all day. It is still raining that way now.
10/3/2015 7:15 AM 1.34 M M M M It rained steadily without a break since yesterday's CoCoRaHS report and it is still raining lightly. Wind was generally 4 - 9 MPH with the strongest gusts to 16.3 MPH. Several times 15.0 MPH was recorded on the WS-2813 station. Wind was NNE to NNW. No flooding is observed and only few old tree limbs about 2" in diameter have fallen down.
10/4/2015 7:15 AM 0.07 M M M M Nearly all day long there was a rainy mist in the air.
10/5/2015 8:00 AM 0.01 M M M M There was no rain or drizzle all day yesterday. The 0.01" precipitation may be due to condensation this AM. There was dew all over everything.
10/6/2015 7:30 AM 0.01 M M M M However, this measurement is not due to pttn but due to condensation and dew. Everything was very, very wet to such a point that water was dripping from the fence rails and chain links and from leaves. There was a fog with limiting visibility of 870'. By 0745 this fog mainly lifted due to the rising sun.

The time period for the rain, which was mildly intense, is below. Between ~1800 and ~1945 I noticed lightning to the East and South. I barely heard the thunder. However the thunder was not with every cloud-to-cloud flash. I saw no lightning between clouds and ground.

10/26/2015 7:40 AM 0.01 M M M M Measurement in rain gauge may be due to condensation as opposed to precipitation. Completely cloudy.

10/28/2015 8:00 AM 0.12 M M M M There was a slight drizzle since daylight. Off towards the mountains (3.5 miles away), they are nearly obliterated by either clouds or rain.
10/29/2015 7:45 AM 2.99 M M M M A light rain began as I took my first recording yesterday but there was no record in my WS-2318 rain gauge until 0935. It rained virtually all day. The heaviest pptn occurred at two occasions. The first was 1805-1825 for 0.61" and 1945-2005 for 0.60". There was also a brief down pour of 0.26" between 2320 and 2330. The rain times are based on the recordings from the WS-2318 rain gauge. Between 1945 and 1955, I was crossing the Potomac River on White's Ferry and there were 3 cloud-to-cloud lightning strikes with thunder. This was nearly due west to nearly overhead. FLOODING: River Road, which is a gravel road, was flooded sometime during the night because it was damaged somewhat extensively this morning. There was a lot of evidence of water wash of the gravel. There was no damage last night when we returned home about 1930. The pond depth increased by 1 1/2 to 2 feet due to runoff from the farm fields and the runoff is still coming.
10/30/2015 8:00 AM 0.01 M M M M I believe that the recording the the rain gauge is due to dew/condensation as opposed to pptn.
10/31/2015 8:00 AM 0.00 0.0 M M M No rain. The 0.01" in the rain gauge is due to heavy dew/condensation. Fog present with visibility to about 400-500 feet. OBSERVATION: Per the WS-2318 weather station, the temp dropped to almost 34F. However there was frost on areas shaded from the rising sun, meaning in some areas the temp was at or lower than 32F/0C.
11/1/2015 6:35 AM 0.00 0.0 M M M No rain but as I was looking at the rain gauge it began to rain lightly.
11/2/2015 7:00 AM 0.04 M M M M There was a trace of rain between 0635 and 0705. Rain picked up just after 0800 and was sporadic throughout the morning till mid-morning.

11/29/2015 7:55 AM 0.32 M M M M I was in Leesburg, VA at 1125 till ~11:40. When I got to White's Ferry there was no rain and no evidence of rain. The same was for my home/CoCoRaHS location. Rain began in the later afternoon about 1715 and <1910 rain stopped. Don't know when rain restarted in the evening and when I collected this mornings measurement it was raining. No flooding so far, but it if continues all day, water run off from the farm fields and pastures will likely produced some minor road flooding.

12/10/2015 8:00 AM 0.08 M M M M Since yesterday we were under fog. It lifted somewhat during the day, but was always at tree level out here. Towards the late afternoon and evening, the fog settled in more and I noticed a slight mist in the air. By this time the water in the rain gauge measured 0.02". This was due to the fog and condensation. During the night, another 0.06" of liquid collected in the rain gauge. My digital rain gauge is in operable at this time for comparison.

12/26/2015 7:30 AM 0.83 M M M M It rained off and on for most of the day. The heaviest though was around 1615-1630. At 1615 we were in Poolesville MD and is was coming down very heavily. Just as we proceeded west towards the Potomac River the heavy rain stopped and turned to a drizzle. At about 1620 we saw a very, very dark cloud between us and the hills across the river. As we got within 5 minutes of our home (24435 River Road), it came down very hard. We could not see more than two telephone poles ahead. After about 2 minutes it stopped. There was no flooding on River Road. At 1650 I went outside toward River Road and noticed that although it was not raining even lightly, the road was totally covered with moving water. It was 5 inches deep. This frequently happens with a lot of rain, as it comes down from the hills and the farmers' fields. Lastly as we were driving home between from Darnestown MD between 1600 and 1630 we noticed many of the streams and creeks had high water, there was puddling on the edges of the road and there was a lot of standing water in the farmers' fields. Every time it rains for a couple of days or when it comes down very heavily, flooding occurs in the fields.

1/10/2016 7:35 AM 1.50 M M M M Yesterday there was a mist in the air all day, collecting only slightly in the rain gauge. Once it began raining, it came down at 0.00 - 0.03" every 5-30 minutes or so. The most rain in a 5 minute period was 0.09" at 0225. Flooding occurred on River Road again. (There is not much of a drainage system on the road, so the rain from the farmers' fields ends up on the road.) Our drainage pond also overflowed, which is typical.

1/23/2016 8:00 AM M 17.8 M 17.5 M Cannot melt snow (at this time) so I put NA in there. The gauge does not collect any where near the amount of snow that has fallen. Yesterday as of 1605 1.75" of snow fell and by 2005 another 1.25" fell. This gives 3 inches on the snow board. Several random total depths today were averaged at 17.8".
1/24/2016 8:00 AM M M M 31.0 M Could not use the CoCoRaHS gauge nor a white board for measurement, except for the first few inches since the first 2.75 inches. I took random snow depth samples at 1700, 23 Jan, in a pasture and got 28.5" of snow since 22 Jan. Then in the AM today, I measured 2.75 inches on a white board between 1700 23 Jan and this morning. It stopped snowing between 2135 and 2145, 23 Jan. I could not take samples for melted snow. (No capability to collect a core sample that deep.)

Just after the rain stopped nearly all of River Road was covered by some water from run off from the farm fields. The edges of the road were probably 4-5" deep. There are no storm drains on this part of the road. The heaviest rain began at 1735 until 1745. It was accompanied by lightning and continuous thunder. At 1739 off to the West it got lighter and after a few minutes the sun was seen. Clouds out there (W) were totally broken up. Between 1720 and 1750 there was 0.48" of rain, as measured by my LaCrosse WS-2813 digital rain gauge. Rain nearly stopped by 1747. The strongest winds were 10 MPH, SE and ESE. A double rainbow was seen directly off to the E. There was no hail.

4/2/2016 7:20 AM 0.13 M M M M It is raining as I took today's measurement. RAIN REPORT for yesterday. Rain first began at 0817 and ended ~0915. In the PM I was in Poolesville, MD and it began raining at 1612 due to a dark cloud above. At 1620, I left town westward and 1/2 mile rain stopped. About 5 miles from MD-MG-103, there was no indication of rain even on the ground. Same at MD-MG-103. At home at 1630 I looked due west and there was a torrent of rain coming down across the river, perhaps 1-3 miles away. Since the wind was from the S, nothing crossed the Potomac River but proceeded N. At the same time I noticed that straight N from my location it was raining. By 1700, it was sunny to the W and above us, with a few scattered clouds. A light rain began at 1741 and ended about 1800. It was completely cloudy with two layers of clouds. Lastly, per the weather station it began raining at 0600, 4/2/16.

The last rain that left 0.05" is recorded below. I don't know when that stopped.

6/5/2016 7:00 AM 0.03 M M M M At 0859 I was in Poolesville, MD and it rained very lightly till I was leaving about 0940. No measurement was available to be taken. At my property is also rained lightly and this was a TRACE. Then overnight, between 0140 and 0215 it rained, according to my LaCrosse WS2813 weather station; see below.
6/6/2016 7:00 AM 0.33 M M M M Between 1606 and ~1700 we had 0.46" of rain, per the LaCrosse WS-2813 weather station and 0.33" per the CoCoRaHS gauge. The wind gusts between 1530 and 1630 were between 15 and 22 MPH. Only a few small branches came down. No power outage and no flooding on the road after the rain stopped. I suppose the difference was due to the blowing wind(?). [I've never had this situation before. Usually the rain comes down too fast for the WS2813 to keep up, not this time.] The two rain gauges are separated by about 150 feet. I also had a trace of rain between 1106 and 1110 - these are exact times.
6/7/2016 8:00 AM 0.00 0.0 M M M
6/8/2016 8:00 AM T M M M M There were two periods of rain that left only a T both times. One between 1511 and 1514 and the other was between 1516 and 1530. Times are exact.
6/9/2016 7:35 AM T M M M M At 1030 I saw it raining directly across the Potomac River, due W. Between 1034 and 1037 the rain made it to this location, then the cloud blew away. It was very windy today with a maximum gust of 27 MPH.

6/16/2016 7:45 AM 0.40 M M M M This may be inaccurate by about 0.04". REASONING: The digital LaCrosse rain gauge WS2813 reported 0.44" over night whereas the CoCoRaHS rain gauge had 0.40", which I reported. I also noticed a somewhat large insect that made it through the collection hole, but probably blocked some rain from coming in. This is the second time that I noticed that CoCoRaHS gauge was lower than the weather station's. Lastly it began raining again as I took this measurement at 0745.
6/17/2016 7:00 AM 0.60 M M M M It rained in the AM between 0755 and 0835 0.04" Then the remainder of the rain came between 1945 and 2240. There was some thunder and the sky lit up several times. The rain appeared to be not too heavy and there was no flooding before I went to bed. However between 2140 and 2240 it rained 0.30". In the AM about 0630 there was a Trace of rain - just a few drops. The sky is quite overcast with indications of more rain to come.

6/22/2016 7:00 AM 1.27 M M M M CORRECTED REPORT. Correction - River Road before White's Ferry Road was flooded because too much water came from the farms. It rained many times then stopped. No noticable flooding by the morning. I have detailed times when the rain began and ended, which was several - 1329; 1416; 1658; 1900. There was a lot of lightning in the night time and thunder was nearly continuous during and after the starting and stopping of rain. It appeared to rain more heavily to the W, N and NW from my observations. I could not discern rain to the S and E, although it did appear to be raining. The sun came out by 1910 and remained that way till sunset, which was beautiful.
6/23/2016 8:00 AM 0.30 M M M M It was raining when I took this measurement. Don't have time now when the rain began. I will amend the report when my LaCrosse transmitter sends to data to the computer.

7/2/2016 8:00 AM 0.01 M M M M Interesting rain situation. NOTE: The farmers out here frequently say that the rain is not the same here at the river as it is across the river or in Poolesville. Today is the case in point. At 1501 the rain began and I left. I had heavy rain all the way to Poolesville, which is East and ~10 minutes away. One mile, still traveling East, before the end of Poolesville the road was dry.

7/14/2016 7:00 AM 0.13 M M M M At 1415 I was crossing the Potomac River, west to east, and there was some blowing rain. I looked up the river and about 1/2-1 mile north it was raining. When I got home, which is about 1/3 mile away there was no sign of rain. Beginning about 2130, I noticed lightning and heard thunder until just after 2200, toward the northwest to north. Our rain began at 2158.

7/19/2016 7:20 AM 0.31 M M M M At 1518, to the west, directly across the river the tree line was partially obscured due to falling rain. At 1521 rain began and across the river, it was raining so heavily that the trees were totally obscured. Between 1534 and 1546 it rained very heavily. All traces of rain stopped about 1615. Winds blew very heavily, unfortunately my anemometer is not working. Several small twigs with leaving came down. This morning about 0630 there was a light rain for a few minutes, leaving 0.02".

7/31/2016 7:40 AM 1.11 M M M M It rained a T at 1617-1620. At 1640 rain began and was slightly steady and somewhat heavy till about 1720. About 1840 there was rolling thunder due west, northwest and north. It appeared to be raining rather heavily, directly at the Virginia side of the Potomac River and W to NW. Dark clouds were rolling from the W. Just before 1900 rain began by 1905 it was very heavy, reducing visibility to about 1/4 mile and dropping about 0.4" in 10 minutes. By 2030 it seems to have stopped completely and the setting sun was visible in the W. No road flooding and and pond came no where near being half full. The ground is very dry. (See forth coming soil tests.)
8/1/2016 6:45 AM 0.73 M M M M At 1600 heard over head thunder and winds began to pick up. By 1603 a deluge came from the sky. In the first 10 minutes of the storm there was 0.40" of rain per the LaCrosse rain gauge. At 1630, there was 0.71" of rain in the CoCoRaHS rain gauge. Visibility during the storm was about 500' to the west and about 1/4 mile to the east. The heaviest rain was between 1603 and 1617. Between 1610 and 1615 it rained 0.34". Highest rain gust was 18 MPH from the N at 1605. Around 1630 when it was stopping the clouds moved high quickly, in that during the storm they were much lower. The only 3 branches came down of 1" in diameter; they were dead already. There was no field flooding as is usually noticed in a storm like yesterday's and today's. That is probably due to the very dry ground dryness. FYI there was only minor street water runoff. There was no water from any field to go to the pond. Little and typical street flooding which did not last after the rain.

At 1906 the winds picked up with the strongest wind gust of 17 MPH from the W. At 1907 rain began very heavily with lightning and thunder. Rain stopped at 1938, then a light rain lasted between 1952 and 2003. Some thunder was heard and lightning was visible, cloud-to-cloud. This lasted till about 2020. The ground is still very dry, so there was no water run off from the fields and no flooding, just puddling.
8/16/2016 8:00 AM 0.64 M M M M Very dark clouds were over head at 1605 and rain began at 1614. At 1615 there were two thunder claps and at 1625 the heaviest rain came down. At 5:18 there were very low (500-1000-foot clouds that were also very dark, but no rain came from them. It was quite windy with gusts between 11 and 14MPH from the NNE to ENE for about 30 minutes. No branches down and no power outage. At 1720 very heavy rain came again stopping at 1750 completely. The CoCoRaHS rain gauge measured 0.38" for this period. There were light sprinkles between 1936 and 1944. Around 2100 there was more rain to bring the total up to 0.64". No road flooding except for puddling and the pond did not seem to increase in depth.
8/17/2016 8:00 AM 0.42 M M M M It began heavy and that lasted for about 10 minutes.
8/18/2016 7:00 AM 1.81 M M M M Rain began at 1906 and lasted for only a few minutes. Then it began again lightly at 2009 and the heaviest came down at 2011 to 2100 when it rained 1.46". There was lightning, thunder (of course) and gusts recorded every 5 minutes from 5 to 12 MPH. Minor flooding occurred on River Road, due to onlyl slight evidence, and there are still large collections of water in lower lying areas. However the ground is still absorbing a lot of the rain. My pond filled up only slightly and in the past with so much rain, the water will still be running down the drainage ditches on the road. This is not happening this morning.
