Lunar Eclipse Photos

I took photos of last nights lunar eclipse using my digital camera and created this animated gif of the eclipse. Click on the photo and you'll see the eclipse from beginning to end.

I took the photos using a very simple Fuji Finepix A340 digital camera set to night mode and scene mode.

New Temperature / Humidity Sensor Installed

The temperature and humidity sensor in my weather station began to fail last week, so I ordered a replacment. It seemed that the temperature readings were okay, but the humidity was way off. Anyway, the replacement sensor arrived this afternoon and I have installed it. While I had the station in pieces, I gave it a thorough cleaning. It had not been cleaned since the spring of 2007. Upon inspection of the station, I noticed some corrosion on the rain collector sensor. I imagine that will be the next part in need of replacement. All the pieces are back in place now though and the temperature/humidity sensor seems to be working just fine now. Hopefully, the station will last for many more years to come.

More Snow

A winter storm warning has been posted for the area through 7pm Friday evening. The snow began to fall today around 2pm and then picked up in intensity quite a bit by 3pm. By 9pm, about three inches of snow had fallen. It was beginning to mix with a bit of freezing rain and sleet at that time too, but it quickly went back to snow. Another round of snow is forecast to hit the area Friday morning and continue through the day. This next round may mix with more freezing rain or it could remain all snow. It's sort of a toss up as to what will happen. School has already been canceled for Friday.

Lunar Eclipse

A total lunar eclipse is set to occurr tonight. Here's some information from NASA's Eclipse website.

A total eclipse of the Moon occurs during the night of Wednesday, February 20/21, 2008. The entire event is visible from South America and most of North America (on Feb. 20) as well as Western Europe, Africa, and western Asia (on Feb. 21). During a total lunar eclipse, the Moon's disk can take on a dramatically colorful appearance from bright orange to blood red to dark brown and (rarely) very dark gray.
An eclipse of the Moon can only take place at Full Moon, and only if the Moon passes through some portion of Earth's shadow. The shadow is actually composed of two cone-shaped parts, one nested inside the other. The outer shadow or penumbra is a zone where Earth blocks some (but not all) of the Sun's rays. In contrast, the inner shadow or umbra is a region where Earth blocks all direct sunlight from reaching the Moon.
If only part of the Moon passes through the umbra, a partial eclipse is seen. However, if the entire Moon passes through the umbral shadow, then a total eclipse of the Moon occurs.

Snow Squall

Today was just your ordinary winter day with cloudy skies, a few peaks of warm sunshine, and snow showers. However, at 4:15 this afternoon all of that changed. I got home at 4:00 and was going through my messages when I turned to look out the window. Wow! The wind had picked up and the snow was coming down hard. It looked awesome out. The wind was whipping the snow around and in just the two minutes since I had looked out the window, the ground was completely snow covered. The temperature was dropping too. Within twenty minutes though, the snow had ended and the sun had come back out. I have to say, this was the most exciting winter weather so far this season.

Windy and Wet Sunday

I've got to stop listening the the weather forecasts. I was expecting a very wet day with the potential for some flooding. We certainly didn't get that though. Instead, we got a whopping 0.23" of rain. I guess some areas to the north and northwest received more, but it certainly didn't turn out to be the type of storm I was expecting. The winds on the other hand, did develop like predicted. The top wind gust here at home reached 39mph at 3:40pm, but stronger winds hit other areas. Here are some top windspeeds from the NWS in Indianapolis:
Peak Wind Gusts from Sunday
LAFAYETTE ...........46 MPH / 209 PM
INDIANAPOLIS......55 MPH / 214 PM
TERRE HAUTE ....49 MPH / 102 PM
MUNCIE ............... 45 MPH / 152 PM
BLOOMINGTON....51 MPH / 133 PM
INDIANAPOLIS EAGLE CREEK 51 MPH / 257 PM

Another Forecast and Another Outcome

Once again, Mother Nature has decided to brush Indiana with only a slight coat of winter rather than slather it on like winters past. Early forecasts for this storm were predicting 6-10 inches of snow in our area. However, as the storm approached less moisture was making its way northward and therefore less precipitation fell. The precipitation that did fall, fell as freezing rain mostly. Overnight, about one-half inch of snow fell and then the freezing rain took over. It was enough to cause travel headaches and close school, but it wasn't the beautiful blanket of snow that we were expecting.

January 2008 Summary

From the NWS in Indianapolis...
The Weather Takes A Wild And Woolly Ride In January 2008
A saying in Indiana is "If you don’t like the weather...wait 10 minutes and it will change." was never truer than in January 2008. On the 29th...one minute the temperature was 54 degrees and raining and less than two hours later it was 27 degrees and snowing...with severe weather and a small tornado occurring in this short time span.
Temperature swings were frequent during January. The first three days of the New Year averaged the lowest at Indianapolis since January 1977. By the 7th the average temperature of 65 was the highest ever recorded for Indianapolis. Just as Indianapolis residents were thinking spring had arrived during that 10 day early January warm spell...winter weather abruptly returned on the 14th. Winter weather conditions through the 26th almost entirely offset the record warmth of the 6th and 7th.
Warm temperatures surged in on the 28th and 29th ahead of a very strong cold front. A squall line formed late in the day on the 29th bringing severe weather and winds over 100 mph in small portions of the Indianapolis area. Winter weather quickly returned after the frontal passage.
When all the extreme weather was totaled and averaged out... Indianapolis had a monthly average temperature of 28.7 degrees...2.2 degrees above normal. The warmest January on record was 1880 with an average temperature of 45 degrees. The coldest was 1977 at 10.2 degrees.
Most of the rainfall during January occurred on the 8th when 1.41 inches fell. Daily melted precipitation on the remaining days of January was less than two tenths of an inch. The monthly total melted precipitation was near normal at 2.14 inches...just 0.34 inches below normal. The driest January on record was 1944 with only 0.21 inches of precipitation. The wettest was only 6 years later...1950...with 12.69 inches of precipitation.
Snowfall for January was also on the light side. Snow fell on 16 days during January. The most snow fell on the 22nd with only 1.1 inches. The monthly snowfall total of 4.8 inches was 4.5 inches below normal.
The strongest wind measured at the airport was 58 mph during the evening of the 29th.
Thunder was heard on one day during January.
Total sunshine during January was 47 per cent of possible.
During the month new record highs were set on the 6th at 63 degrees and 7th at 68 degrees and a new high minimum was set on the 7th at 61 degrees. A new daily rainfall record was set on the 8th with 1.41 inches. There were no low temperature records set during January.

Stick a Fork in It... She's Done

Bust! That's all I can say for most forecasts across the area. The low pressure system decided to take a more westerly route across the area which pumped in a lot more warm air than was anticipated. The snow forecast amounts were pushed west as a result. Indianapolis was expecting about 6 inches of snow and received less than an inch. Lafayette was expecting nearly a foot of snow and received only 3.5 inches. Areas in western Illiniois however, received much more snow than was originally forecast. This just goes to show that you can't predict Mother Nature with much certainty at all.
Here at home, the snow/sleet/freezing rain began to fall around 10pm. It began as a heavy burst of sleet accumulating to about a half inch. There was some snow mixed in with the sleet. Eventually, the sleet turned to freezing rain and rain as the temperatures rose through the night. Temperatures rose from 28 at 10pm to 36.5 at 8:30am. Temperatures are currently heading downwards though. I'm assuming this is because the winds have shifted a bit. Temperatures are forecast to fall through the day today.

Highways are in excellent condition this morning, but back roads in my immediate area are covered in a thick sheet of ice. The sleet that fell at the onset of the storm melted into a mass of ice on the roadways. There has been very little traffic on the road this morning, and there have been no county trucks sanding. School is closed today.

On to warmer weather for the weekend and next week. There's still plenty of February left though!
