10/1/2009 7:00 AM 0.60 M M M M This rain began around 3:00 AM. We had a few really close strikes, but no heavy rain. Was raining lightly at observation time.
10/2/2009 7:00 AM 0.21 M M M M I saw a storm around 4:00 PM go to our north. I think I read some special weather statements about that storm a little bit later. At 4:20, it started raining lightly, then a heavy downpour started at 4:30 and lasted for five minutes. The rain was over at 4:45.

10/9/2009 7:00 AM 3.28 M M M M This rain fell in two periods. One was from observation time until around noon. (1.68) After a break of about one hour, it started up again and never quit until around 6:30 PM. (1.60) I calculated that we were getting 0.15" per hour. In total, we have gotten 6.41 inches in the past 36 hours. That is more than we have ever received in that much of time.

The new snow depth was 1.5 inches. It melted down to 0.08 making a very dry snow. Wind remained steady at around 10 to 15 mph all day. This combined with the 19°F temperature made the wind chill very cold.

1/15/2010 7:00 AM 0.00 0.0 M M M More snow melted. If there was more sunshine that it would probably be all cleaned up, but the clouds are keeping the temperature near steady.
1/16/2010 7:00 AM 0.00 0.0 M M M Dense fog outside. The temperature was freezing, so freezing fog did develop on our driveway and sidewalks. The fog though did not clear up as the forecast said it was supposed to.

1/24/2010 7:00 AM 1.56 M M M M I was surprised that this much rain fell. It rained steadily all day yesterday. Creeks are up and the water table cannot be very low.
1/25/2010 7:00 AM 0.01 0.1 0.01 M M Cloudy and 30°F with flurries. The brisk west-northwesterly winds are keeping the wind chill to below freezing. It flurried throughout the night and all today slackening to a halt by 3:00 PM.
1/27/2010 7:00 AM 0.00 0.0 M M M Cloudy and 24° at 7:00 AM. I might be wrong, but the grass almost had a frosty appearance to it. The winds have appeared to subsided which makes it a bit more comfortable outside than yesterday. It looks like a big winter storm for the folks down south, but it looks like we will just get brushed by it.
1/28/2010 7:00 AM T T T M M Mostly clear with a light breeze out of the West Northwest and a temperature of 18°F at 7:00 AM. A layer of light frost was sporadic on the ground. The trace was from some sleet that fell around noon yesterday. It stuck as it fell, but after it had been on the ground for a half an hour, it melted.
1/29/2010 7:00 AM 0.00 0.0 M M M Cloudy and 18°F at 7:00 AM. The wind was northeast at 3-4 mph. The interesting thing about this storm is that the central pressure of this storm is only 1010milibars or 29.80 inches.

2/2/2010 7:00 AM 0.00 0.0 M M M Cloudy and 36°F this morning at 7:00 AM. West wind of 2 to 4 mph.
2/3/2010 7:00 AM 0.00 0.0 M M M Another colorful sunset occurred today. The temperature was 24°F and the sky was mostly clear with a few medium height clouds. The wind was calm and a light frost occurred.
2/4/2010 7:00 AM 0.00 0.0 M M M This morning had a consistent altostratus cloud cover to it. The wind was light from the southwest and the temperature was 34°F. I would be surprised if the precipitation onset tonight comes in as all snow, as the temperature is near 38°F.
2/5/2010 7:00 AM 0.23 0.8 0.23 M M Well, I was wrong. The precipitation fell all as snow. However the snow is a very wet snow has partially melted on the way down. If it were not so warm we would have some substantial accumulations by the time this storm is over. I measure .8 inches of snow on the board. The temperature was 34°F and the wind was calm.
2/6/2010 7:30 AM 0.32 1.0 0.32 M M Cloudy and 33°F at observation time. This is probably the wettest snow that I have seen. The ratio is about 1:3 ! The grasstips are showing through, but it makes for nice sculptures. :)

At 9:00 P.M. the rain changed over to a light/moderate wet snow. This snow dropped a half an inch in just over half an hour. Had this precipitation kept on for a few more hours accumulations would have stood at several inches. But that is not just how Missouri weather is.

3/10/2010 7:00 AM 0.49 M M M M Around 6:00 P.M. I heard a faint roll of thunder. This is all I heard and was the first thunder that I heard this year. This rain occurred from 6:35 P.M. to 7:00 P.M. At times around 6:45 the rain was moderately heavy.
3/11/2010 7:00 AM 0.54 M M M M This rain fell in two periods. The first occurred around 5:15 P.M. till 6:00 P.M. I watched this storm move in from the south. Lightning was not prolific in the storm at all and I only saw intra-cloud lightning. At 5:15 some sprinkles began and at 5:30 the rain from the cell set in. It was not quite of moderate intensity and was accompanied by wind of 5-10 mph with gusts up to 15 mph. The second storm was part of a line of thunderstorms and affected us beginning around 9 P.M. The actual line was quite a few miles west of us and we only got scraped. To the west and a little north, there were several cloud to ground strikes (a few fairly close). This morning the sky is clear with a temperature of 46°F.

3/26/2010 7:00 AM 0.04 M M M M Clear skies with a temperature of 33°F. A good frost lay on the ground and the near freezing temperature had half frozen the rain that was in the inner tube of my rain gauge. I suppose that this rain occurred in a short shower yesterday morning but I do not recollect having seen anything of that nature.

4/3/2010 7:00 AM 0.99 M M M M A thunderstorm appeared toward the west around noon yesterday but apparently dissipated quickly, for nothing reached us. However, at 1:05 rain spread in. This first shower was accompanied by no thunder and was over in about a quarter of an hour. An extended light rain period occurred from 1:45 till around 4:00 P.M. Apparently more steady rain fell last night for there was almost one inch of rain in my gauge this morning.
4/4/2010 7:00 AM 0.00 0.0 M M M Sky is completely overcast with alto-stratus this morning with a temperature of 53°F this morning. It is going to be a nice day for Easter.
4/5/2010 7:00 AM 0.38 M M M M Around 5:00 P.M. I saw the anvil of a thunderstorm a long way off to the north. I did not think much about it until it was dark enough to see the lightning. Apparently a line of thunderstorms had developed. The storm hit us around 9:00 P.M., but we did not get any severe weather. This was because one cell went to our north and one to south. I heard later that the northern cell produced small hail while the southern cell produced torrential rainfall.
4/6/2010 7:00 AM 0.00 0.0 M M M Partly cloudy with a temperature of 68°F. Quite a bit warmer than yesterday morning. Winds were steady at 3 mph and gusting to 8 mph. It looks like a start to a breezy day.
4/7/2010 7:00 AM 0.47 M M M M A thunderstorm or storms hit us from 2:00 A.M. till 3:30 A.M. The wind changed to north in the event. No significant weather occurred but there were a few close lightning strikes that rattled the windows. Cloudy with a temperature of 59°F this morning.
4/8/2010 7:00 AM 0.08 M M M M At 6:45 P.M. I saw two rain clouds to the south. I watched them for a while until I got rained out. The first cell moved off to the south and we only received a very few sprinkles. The second cell was larger and I saw one intra-cloud lightning stroke. Sprinkles became light rain which persisted for about 20 minutes. All the while there were fairly moderate winds of 15 mph. I am not sure when the rain stopped but I know that it sprinkled for one or two hours after 8:00 P.M. Clear with a temperature of 37°F this morning.
4/9/2010 7:00 AM 0.00 0.0 M M M Clear this morning with a temperature of 31°F in my weather station. The grass near the house did not experience any freezing but further away there was a light coating of frost. However even it was mixed with some dew. It is going to be a beautiful spring day.
4/10/2010 7:00 AM 0.00 0.0 M M M Clear skies and 46°F. Just a bit of dew, but not much with a relative humidity of 78%.

4/12/2010 7:00 AM 0.00 0.0 M M M Clear skies with a temperature of 46°F this morning. A light to moderate dew on the grass.
4/13/2010 7:00 AM 0.00 0.0 M M M Just a few cirrus clouds in the sky this morning, but there were many contrails, so moisture must be building back into the upper atmosphere. There was a light dew and the temperature was 56°F. The soil in our garden is dry enough to till now, so I guess the work is cut out.
4/14/2010 7:00 AM 0.00 0.0 M M M Clear this morning with a temperature of 54°F. A light dew.
4/15/2010 7:00 AM 0.00 0.0 M M M This is the third morning with a temperature of 54°F, but it looks like it will be the last for a while. This cold front is supposed to put an end to this nice weather. Cumulus clouds and cirrus have been the predominating feature of today with winds from the southwest...Cold front hints.
4/16/2010 7:00 AM 0.00 0.0 M M M 57°F and 87% relative humidity at observation time.
4/17/2010 7:00 AM T M M M M 36°F at 7:00 A.M. Relatively calm conditions with the barometer steady. The ridge will continue to keep us supplied with cooler and dry conditions for a few days.
4/18/2010 7:00 AM 0.00 0.0 M M M 33°F and 90% humidity. Near the house light dew had collected but further out in the yard, a very light frost had formed.
4/19/2010 7:00 AM 0.00 0.0 M M M 40°F with a cirrostratus cloudcover. I have been quite surprised at the already slow weather patterns this year.
4/20/2010 7:00 AM 0.00 0.0 M M M 35°F with just a few cirrostratus clouds in the sky this morning. With the clear skies today, the temperature should rise considerably. I am looking forward to the possibilities of thunderstorms coming up. It seems so long a time since we had some action in the atmosphere.

4/22/2010 7:00 AM T M M M M Moisture laden cumulus clouds increased throughout the evening quickly turning the sky overcast. Around 4:00 P.M. a ten minute shower moved through. Another short rain even occurred at 6:20 P.M.
4/23/2010 7:00 AM 0.35 M M M M Cirrostratus spread in during the morning giving way to altostratus by noon. Around 2:00 P.M. low clouds began to move in. At 2:30 sprinkles began which continued until light rain commenced around 3:00 P.M. As far as I know, the rain remained steady and was continuing around 9:00 P.M.
4/24/2010 7:00 AM 1.27 M M M M Stratocumulus cloudcover this morning and 66°F. There were two main rain period-one in the morning and the other towards evening. The one in the morning produced 0.87" of rain while the one in the evening produced 0.49" of rain.
4/25/2010 7:00 AM 2.65 M M M M The rounds of rain that moved through last evening caused much rain as predicted. I believe this is the largest amount of rain this year that I have measured.
4/26/2010 7:00 AM 0.06 M M M M 50°F with stratocumulus clouds this morning. This precipitation fell in the form of a persistent mist all of yesterday.
