Short Poet started this thread to post weather conditions around the country, temperature, rainfall, snow fall storms and so on. For myself personally, I thought it would be good because it provided a record to compare from people all over the United States. In my work, I spend a lot of my time talking to companies about maximizing water resources, integrating water management and water and energy, so it provided me with a good comparison to share with people when I discuss the relationship of current weather to our ongoing water resources.
Here is a little information regarding this area.
The little town of Masterson Texas was the closest town to the area of the huge hail storm, it sits between Amarillo and Dumas Texas in Moore County, it’s in the area of the Northern Panhandle very close to where my husband family cattle ranch is. The weather has always been unpredictable and rain, well it’s rare, usually around 12 inches a year, not much. People lives and livelihood depend on how well they understand and can try to predict the areas weather and water resources.
The current tornado season demonstrates just how volatile the weather can be. Called tornado alley for decades for good reason, now more are occurring earlier and are more sever when compared against 1998 and onward and tracked to records from the last 100 years. Simply there are more F3, F4, and F5 tornado.s happening earlier and at 2 to 3 time’s normal levels over the last 100 years. The reason being that the arid plains and grasslands trap more heat than forested areas, generating the heat engine that collide with colder air masses coming from the western mountains.
This is all in stark contrast to the drought which has gripped this area for so long. My husband family stopped running cattle in 2010 as the drought that has been escalating for the last 12 years got much worse. In 2011 the severe drought killed trees that were over 50 years old. Lake Meredith which provides water to 14 Texas towns in this area is at record lows of 30 feet compared to the record high of 101 feet in 1973. Like the drought it has been dropping for almost 14 years straight. It depends 100% on rainfall. Unlike South Texas, which had flooding in some areas of 2011, these northern areas are away from the Gulf of Mexico monsoon weather currents. Literally these are a tender box away from starting what geologist call mass desertification events.
So put together severe storms that generate lots of lightening, high winds, and tornado's and very little rain, accept in little localized extreme cases and the risk of fire goes way up. State disaster experts are already warning that this fire season may be another new record.For me personally a huge example of how climate change has been and continues to affecting the central United States.
In this area of the country farmers and ranchers depend on the Ogallala Aquifer ( the largest in the United States) to provide water to an area from South Dakota in the North to Midland and Odessa Texas to the South, that generates over 60% of the Beef Cattle, 80% of the Cotton. The reason is that about 27 percent of the irrigated land in the United States overlies this aquifer system, which yields about 30 percent of the nation's ground water used for irrigation. In addition, the aquifer system provides drinking water to 82 percent of the people who live within the aquifer boundary of 8 states. The Ogallala is an unconfined aquifer, and virtually all recharge comes from rainwater and snowmelt. As the High Plains has a semiarid climate, recharge is minimal and has been dropping due to the droughts and overuse.
Now this is purely personal; I believe we are seeing the Central Plains of the United States transforming from Semi Arid to more desert like conditions over a very short period of time. Literally I believe the desertification of the Central Area of the United States above and surrounding the Ogallala Aquifer. Sorry for the long post but, again personally this is one of the biggest reasons why I became a believer in climate change almost 20 years ago and realized the role weather was going to have on water resources in the future.
