We’re now about three fourths of the way through January, and just about two thirds of the way through Winter. December was 2.7 degrees colder then normal (15th coldest on record) and the second wettest on record, with 9.1 inches of rain. So far in January, Atlanta Hartsfield-Jackson airport is 5.4 degrees colder than normal, but with 2.19 inches of precipitation, only 54% of normal. With more rain predicted for Sunday, and again at the end of the week, we could easily get back to normal January precipitation of 5.03 inches. The verdict for the first part of Winter would have to be colder and wetter than normal.

Looking forward to February, and anticipating the groundhogs next month, the early part of spring, it looks like we can expect more of the same. The Climate Prediction Center released its February outlook earlier this week, which is reproduced below:

As is typical for El Nino winters, it’s likely to be colder than normal for much of the Southeast, and warmer than normal for the Northwest. The remainder of the country could be above or below normal. On the precipitation side, most of the southern half of the country will be wetter than normal, with equal chances of dry or wet weather in the north. The greatest chance of excessively wet weather is in southern California and Arizona, not welcome news for an area which has seen extensive flooding this week.

Last week, someone managed to access emails and other information from the Climate Research Unit of Britain’s University of East Anglia. The CRU is charged by the British Met Office to investigate global warming, and is responsible for much of the research into the field. These emails and files were posted to a public site, and the evidence they provide does not reflect well on the scientific method of the researchers.

Among other things, the files show that CRU scientists and their partners across the world tried to silence those who didn’t agree with the CO2/Global warming theory, tried to prevent others from accessing the data they used to make their predictions and used methods to falsify data that was later presented to the United Nations IPCC. Officials with the university confirm that information was taken from their servers, and the emails, etc. appear to be genuine.

If all this is true, it poses a real problem for the scientific community and for the theory that climate change/global warming is a big problem.

Here are some links to more information:

Evidence that the “Hockey Stick” chart showing future increases in temperature used deceptive data
Comments in program code used to create temperature series are further evidence of data manipulation
Wall Street Journal says climate scientists are trying to hide the truth
Three things you must know about Climategate
This research is the foundation for new, expensive regulations on the US economy

There’s a lot more out there, if you search for it. It will be interesting to see how this plays out, especially with the Copenhagen talks coming up next month.

The latest drought report, as of July 14th, lists just over one third of the state of Georgia as being abnormally dry, including metro Atlanta and Gwinnett. This is despite the one to three inches of rain that fell on Sunday. While this may seem ominous, keep in mind that a year ago over half the state was in a severe drought.

The other bit of good news is that the drought outlook isn’t calling for any drought to develop east of the Mississippi River through October. There’s a better than even chance for precipitation tonight and tomorrow, and both the 6-10 and 8-14 day precipitation outlooks for Georgia are calling for wetter then normal weather.

In addition, both the one month and three month outlooks for August and August through October are calling for equal chances of above and below normal temperature and precipitation.

A month after the climatologists said that the North Georgia drought was over, the state Environmental Protection Division has caught up. As of today, most watering restrictions have been lifted throughout the region. You are still limited to watering on your assigned odd-even days, either Monday, Wednesday and Saturday or Tuesday, Thursday and Sunday, but you can water any time you like.

The EPD does recommend that you not water between 10 AM and 4 PM, since during those hours more water can be lost to evaporation, making watering less useful. This is a return to level one watering restrictions. Level two restrictions, which we were under for much of 2007, limited watering to between midnight and 10 AM. We never were subjected to level 3 restrictions, which would have limited watering to a single day a week.

Before you turn on those sprinklers full blast, though, be aware that water rates have changed since the last time we were drought free. The big change is a summer surcharge for excessive water use. For example, in Gwinnett County, you could pay twice the normal rate per 1,000 gallons for amounts above 20% of your average use from January through March.

Compared to the past few years, the weather this spring in North Georgia has been wet. Virtually the entire state reported above-normal rainfall in April, which followed a wetter than normal March.

Some unofficial reports of rainfall totals in April were over ten inches in South Georgia, while the highest official total was 7.3 inches in Alma, over four inches above normal. Atlanta was 1.56 inches above normal for April, and Athens had 1.12 inches above normal precipitation.

May has gotten off to a wet start as well. As of May 6th, Atlanta had recorded 2.05 inches of rain, which is 1.31 inches above normal for the first week in May. With this morning’s storms and chances of more wet weather still ahead through the weekend, we are close to reaching the 2.8 inches of precipitation recorded for all of May, 2008, and will have more May rain than since at least 2004. Normal May rainfall in Atlanta is 3.95 inches for the entire month.

Lake Lanier continues to fill as well. The lake level is at 1064.95 feet at Buford Dam, 7 inches above where it was when the current rains started a week ago, and just six feet below full pool.

The latest drought outlook from the Climate Prediction Center says,

Several inches of precipitation are forecast in the short-term for the last vestiges of the once expansive drought that covered the interior Southeast. Given the expected heavy precipitation through the forthcoming weekend, and nothing indicating enhanced probabilities for significantly below-normal rainfall through the end of July, it seems likely that we will finally be able to close the books on this protracted and at one time serious, large-scale drought that has been affecting the Southeast for the last 3 years.

And, State Climatologist David Stooksbury reported earlier this week that conditions on Lakes Lanier and Hartwell have improved to mild drought from moderate drought because of the increasing lake levels. The rest of the state is drought free. He reports above normal soil moisture for most of the state, and normal to above normal stream flows. He says,

May is typically one of the drier months in Georgia. Additionally, with high temperatures routinely in the 80s and plant water use very high, moisture loss is accelerated. We normally expect the soils to start to dry out this month.

As we progress through the summer into the middle of fall, moisture loss from the soil – due to evaporation and plant use – is normally greater than rainfall. With normal weather over the next several months, Georgians can expect to see a drying of the soils. However, this is normal and does not mean that Georgia is heading back into a drought.
