Top U.S. weather story of 2007: the Southeast U.S. drought

The year 2007 is in the record books as the driest or second driest year on record for much of the Southeastern U.S. A mere 31.85 inches of rain fell in Atlanta, Georgia, during the year, 62% of the average of 48 inches. This year's rainfall total just missed breaking the record of 31.80 inches set in 1954. Rainfall records in Atlanta go back to 1930. The drought was worse in Alabama, where Birmingham had its driest year on record--just 28.86", a full 25 inches below average, smashing the record low of 36.14" set in 1931. Huntsville was even drier--a mere 28.65"--29 inches below average. Surrounding areas of Tennessee, North Carolina, South Carolina, Kentucky and Virginia also experienced extraordinarily dry years (Figure 1).


Figure 1. Drought conditions in the Southeastern U.S. were at the highest level possible--exceptional drought--at the end of 2007. Image credit: NOAA.

Although the current drought is exceptional, Atlanta has had much drier 2-year periods. During the drought of 1954-1955, Atlanta received 68.23 inches of precipitation--a 28 inch deficit from the normal 2-year rainfall. The deficit for the past two years is only 16 inches, since an average amount of rain fell in 2006 (48.46 inches). Based on the climatological record, Georgia can expect a two-year drought about once in 25 years, and a drought lasting three or more years about once every 40 years. Drought is part of the natural cycle in Georgia, and it would not be a surprise to see the drought of 2007 continue until the winter of 2008. Although December 2007 saw Atlanta's first above average month of rainfall since November 2006, the coming two weeks look very dry, and the current La Nina atmospheric pattern usually brings below average rainfall.

What is causing the Georgia drought?
Two main factors are responsible for the Southeast U.S. drought. Most importantly, a persistent jet stream pattern has set up that steers storms away from the region, and into Texas instead. Texas, which suffered extreme drought in 2006, found itself awash in floods in 2007, as the jet stream pattern brought storm after storm to the state. Another contributing factor to the current Southeast drought is the absence of tropical storms and hurricanes during 2006 and 2007. These storms are an important part of the annual rainfall budget for the Southeast. For example, in 2005, 29% of Atlanta's yearly rainfall came from five tropical storms:

1.36" Arlene June 11-12, 2005
1.40" Katrina, August 29-30, 2005
5.48" Cindy, July 6-8, 2005
5.41" Dennis, July 9-12, 2005
2.94" Tammy, October 6-8, 2005


Figure 2. Over ten inches of rain fell on Atlanta in 2005 from two tropical cyclones, Dennis and Cindy. Tropical cyclones accounted for 29% of Atlanta's rainfall that year. Image credit: NOAA/HPC.

There is little evidence that global warming contributed to this drought. The Southeastern U.S. has cooled by about 0.1° F over the past 100 years, even as the rest of the globe has warmed 1° F. The reasons for this lack of warming in the Southeast are not fully understood. One theory is that the cooling is due to air pollution blocking sunlight. Another theory, proposed by Georgia State Climatologist David Stooksbury, attributes the cooling to the shift from 80 percent row crops (like corn and cotton) to 60 percent forest. Land use changes like this can have a significant impact on how solar energy heats the air once it is absorbed by the soil.

Why Atlanta is vulnerable to drought
Atlanta, unlike most major cities, grew up around rail lines rather than a major body of water. Although the Chattahoochee River runs through Atlanta, the city lies on top of a watershed, with no large bodies of water upstream. The rivers and streams in the region are small, and the bedrock limits how much ground water is available. The Lake Lanier reservoir that supplies Atlanta with most of its water was constructed in the 1950s. Since that time, the population of Atlanta has quadrupled, increasing the pressure on the reservoir's limited water. Lake Lanier is at its record lowest level--more than 19 feet below average. If the drought continues into the summer of 2008, and no tropical storms arrive to break the drought, Atlanta may run out of water.

By 2030, the population of the Atlanta metropolitan area is expected to increase from 5 million to 9 million. Current water resources in the regions will be unable to support this population increase, unless planners make a concerted and expensive effort to plan ahead. The expected increase in temperatures over the coming decades due to global warming will make future droughts in the region even more severe, so Atlanta has a very tough road ahead of it.

Georgia Drought Series 2 (HurricaneIan)
Like my last series, this Series of photos concern the drought in North Georgia. These were taken at Lake Chatuge, Georgia. This is near the North Carolina Line and near a town called Hiawassee. North Georgia is experiencing a major drought. These docks are designed to float and adjust to water depth, however, now they are high and dry. The depth of these lakes varies from season to season, however, this is by far the lowest I have ever seen it. This water is not only used for drinking, this is also the primary supply of hydro-electric power for the region. The drought is causing other problems as well, the leaves are not changing properly, some look burnt and others fall off before turning. North Georgia and surrounding areas need rain in the worst way. The good news is it is raining

Here are a few scenes from Lake Lanier in Buford, GA. We are going through a record setting drought this year. Everyday now we set a new record for the Lake level since the inception of the lake in the 1950's

Avery nice Snow band is ofshore central Florida moving to the Southwest.
No Flurries being reported yet as the bulk of the precip is still ofshore.
It is currently in the low to mid 30's along the space and treasure coast enough to support some flurries or a rain/snow mix.
These showers are quickly moving to the SouthWest and it will be interesting to see which area get some snow.

TROPICAL CYCLONE ELNUS ADVISORY NUMBER FIFTEEN
============================================

At 6:00 AM UTC, Tropical Depression, Ex-Elnus [998 hPa] located near 22.5S 40.8E or 1495 kms west of the coast of Reunion had 10 minute sustained winds of 30 knots with gusts up to 45 knots. The storm is reported moving south-southeast at 7 knots.

Dvorak Intensity: T2.0/2.5

Near Gale-Force Winds within 30 NM from the center extending up to 90 NM in the southwestern quadrant and up to 140 NM in the southeastern quadrant, and locally reaching 35kts in the southeastern semi-circle up to 30 nm from the center.

Strong gusts under squalls.

Forecast and Intensity
======================
24 HRS: 24.0S 41.0E 35 knots (Tempête Tropicale Moderée)
48 HRS: 24.9S 41.4E 30 knots (Depression Tropicale)

Additional Information
========================
The low level circulation center is partially exposed northwest of the deep convection due to a rather strong northwestly vertical wind shear. Elnus should track southward for the next 36 hours and take advantage of a decreasing wind shear to slightly re-intensify to moderate tropical storm stage. Beyond located between two upper level ridges, the first shifting eastward and the other rebuilding in the west, the system should track southeastwards.

If the temperature bounce back begins tomorrow the citrus crop may be okay. The cold may be just a good mosquito culler.

There will be one inhibitor for temperatures to fall near the dew point. Low level stratocumulus clouds continue to advect SW as high pressure moves east giving a north-northeasterly flow to the east coast of Florida overnight. The clouds will act to prevent radiation cooling (the process by which heat escapes the earth's surface) should they make their way onshore. Currently dry air evident on water vapor imagery is pressing against the strato-clouds which could lead to even more surface divergence along the east coast.

P451...as far as bottoming out it doesn't look good. Dewpoints are really low, and not much to keep temps from approaching them.

This one night shouldn't take out the Florida citrus, but tomorrow night may.

Here what the NWS is talking about. You can the the precip. of shore 40 miles away from Flagler Beach. They are moving to the SSW likely to miss that area as the precip is at the same latitude but neverthe less this will be monitor for areas a bit farther south.

IMMEDIATE UPDATE ON TROPICAL LOW 06U
====================================

At 4:00 AM UTC, Tropical Low [995 hPa] located near 14.1S 128.2E or 155 kms north of Wyndham and 345 west-southwest of Darwin had 10 minute sustained winds of 30 knots with gusts up to 45 knots. The low is reported moving west at 6 knots.

There is the possibility that the low will develop into a TROPICAL CYCLONE tonight, and GALES could affect coastal and island communities between Mitchell Plateau in Western Australia and Daly River Mouth in the Northern Territory overnight or early tomorrow morning.

Heavy rain is expected to cause flooding in the north Kimberley region from tomorrow.

Tropical Cyclone Watches/Warning
===============================

A Cyclone WARNING is current for coastal and island communities from Mitchell Plateau in Western Australia to Daly River Mouth in the Northern Territory.

A Cyclone WATCH is current for coastal and island communities from Daly River Mouth to Goulburn Island, including Darwin and the Tiwi Islands

NWS Melbourne


VERY COLD TEMPS AND WIND CHILLS OVERNIGHT WITH LONG DURATIONS
BELOW FREEZING AND A HARD FREEZE INTERIOR...

...A FEW FLAKES OF SNOW POSSIBLE ALONG THE COAST FOR A FEW HOURS
EITHER SIDE OF SUNRISE...

.DISCUSSION...

CURRENT...AS OF 02Z TEMPS HAD ALREADY FALLEN TO A DEG OR TWO ABOVE
FREZZING ACROSS MOST OF THE RURAL FAWN SITES NORTH OF I-4. OTRW...
TEMPS GENERALLY RANGE FROM M30S NORTH TO NEAR 40F SOUTH. TD`S VERY
LOW ATTM...SINGLE DIGITS AND LOW TEENS NORTH...MID/UPPER TEENS TO
THE SOUTH.

3.9UM IR IMAGERY SHOWS MARINE SC HAS ALREADY DEVELOPED RIGHT ALONG
THE EAST COAST FROM KX47-KDAB-KTTS AND IS INEXORABLY PROPAGATING
SHOREWARD SOUTH OF THERE AS WELL. KXMR 925 PROFILER DATA INDICATES
WINDS FROM ~340 @25-30KT FROM JUST OFF THE DECK TO ABOUT 2.5KFT...
AND AROUND 360 @25-30KT IN THE 3-6KFT LAYER...SO NO SURPRISE THAT
THE CLOUDS ARE ALREADY IMPINGING OVER THE NERN COAST.

ALSO OF NOTE IS THE LIGHT RADAR REFLECTIVITY RETURNS WHICH DEVELOPED
WELL OFFSHORE NE FL AND HAVE BEEN PROPAGATING SSW TO A POINT WHERE
THE WRN EDGE IS ABOUT 40 MILES OFFSHORE FLAGLER BEACH. PATTERN WHICH
CAN LEAD TO RARE OES (OCEAN EVENT SNOW) NEAR THE COAST IS SETTING UP
PRETTY MUCH AS ADVERTISED (GRANTED...AS AN EVENT IT`S REALLY MORE OF
A NOVELTY THAN HAVING SIGNIFICANT EFFECTS ON THE GENERAL POPULACE).



W/R/T FREEZING TEMPS AND LOW WCI`S...THE CURRENT FCST LOOKS PRETTY
DECENT FOR THE MOST PART. WE MAY HAVE SOME TROUBLE REACHING FREEZING
ALONG THE EAST COAST...ESPECIALLY IF THE CLOUDS HOLD TOGETHER AND
START TO COME ONSHORE EARLIER THAN ANTICIPATED. TEMPS THERE SEEM MORE
LIKELY TO REACH THERE LOWS WITHIN THE NEXT 6HRS BEFORE TRENDING MORE
HOLDING STEADY A FEW HRS PRIOR TO SUNRISE. RURAL WESTERN SECTIONS OF
THE COASTAL COS STILL STAND A MUCH BETTER CHC OF REACHING THE
FREEZING MARK...SO NO REAL REASON TO TWEAK FREEZE WARNINGS. OBVIOUSLY
...WILL MONITOR TRENDS ON RADAR/3.9UM IR INTO THE OVERNIGHT HOURS
TO SEE IF CLOUDS/LIGHT PRECIP RETURNS CAN HOLD TOGETHER AS THEY
MOVE WITH INCRSG SHOREWARD COMPONENT. STRONGLY SUSEPCT THAT INITIALLY
THE WRN EDGE OF THE CLOUDS WILL ERODE AS IT BUTS UP AGAINST THE VERY
DRY/COOL AIR OVER THE PENINSULA...HOWEVER AS THE 0-2KM WINDS CONTINUE
TO VEER THROUGH EARLY THU MORNING...OCEAN MODIFICATION WILL BRING AN
END TO THAT TREND. NEVERTHELESS...MAY TWEAK TEMPS RANGE FOR VOLUSIA
COUNTY TO ADD A LITTLE WAMRER READINGS NEAR THE BARRIER ISLANDS.

1030 PM EST WED JAN 2 2008

.UPDATE...LATEST SURFACE ANALYSIS REVEALS TEMPERATURES ARE NEAR
THE FREEZING MARK IN PORTIONS OF GLADES COUNTY AT THE MOMENT BUT
MOSTLY IN THE MID TO UPPER 30S ELSEWHERE ACROSS GLADES...
HENDRY...AND INLAND COLLIER COUNTIES AND IN THE LOWER TO MID 40S
ELSEWHERE AT THIS TIME. LATEST GUIDANCE CONTINUES TO SHOW A

MONROE...AND INLAND SECTIONS OF PALM BEACH TO MIAMI DADE COUNTIES
WELL AWAY FROM THE EAST COAST METRO AREAS. HOWEVER...TEMPERATURES
ACROSS THE EAST COAST ARE STILL FORECAST TO FALL INTO THE MID TO
UPPER 30S AND TEMPS CLOSE TO THE FREEZING MARK CANNOT BE RULED
CLOSE TO THE WESTERN MOST EDGE OF THE METRO AREAS. A FREEZE IN
SOUTH FLORIDA ACROSS ANY GIVEN AREA IS DEFINE BY MIN TEMPS
REACHING THE 32 DEGREES MARK FOR ANY PERIOD OF TIME REGARDLESS OF
COVERAGE.

WHAT IS UNLIKELY AT THE PRESENT TIME IS TEMPS OF 28 OR LOWER FOR
AT LEAST 4 HOURS ACROSS THE NW INTERIOR WHERE A HARD FREEZE
WARNING IS IN EFFECT. BUT THERE IS STILL A POSSIBILITY ALBEIT
SMALLER GIVEN LATEST TRENDS...GUIDANCE...AND AN ANALYSIS OF THE
ENSEMBLE DATA. HOWEVER...GIVEN MIA 00Z SNDG 1000-850MB THICKNESSES
ARE AROUND 1315 METERS...WHICH IS ONLY EXCEEDED BY THE VALUES OF

Here in sw FL, s. of venice is experiencing the coldest conditions in a long time. I can't remember the last time it's been this cold, roughly 5-10 yrs or so. Only 49 for a high, already down to 35 here now. Very rarely gets below freezing

Just checking in again; I had to step out for a while.

Low tonight in Nassau is supposed to be 58, with the wind chill making it feel like 48. In the extreme NW Bahamas it's supposed to drop to 48, with a similar wind chill. Our record low here (Nassau) is the mid-40s, if I remember correctly (I need to research this lol).

I don't know if we're going to have any records broken in Freeport or Abaco tonight. It's possible, I suppose.
