The 'condition' of the land has a direct effect on climate.

Despite rains that have visited Texas in recent weeks, the drought is profound.

In the satellite picture below it is noted to have a heat transfer system extending from Mexico to the eastern third of the country.

There is an 'interruption' in the image over the extremely dry southern tip of Texas.  That is not simply 'the weather' is a result of 'the drought.'

The land in Texas is so parched it does not lend itself to rainfall. 

When the weather system passes over poorly conditioned land the air heats up and absorbs the heat.  As a result the 'water vapor' contained in the weather system is evaporated. 

The reason Texas is remaining unrecoverable from the drought is because it has created its own hostile climate outcome.

One of the remarkable climate on the West Coast is contained in the Redwood Forest.  There is not necessarily rain in the region in general, but, every morning when the ocean mist rests over the Redwoods it accumulates a humidity within the trees themselves due to the trees use of water for growth and nutrition.  As the day progresses and the trees 'respirate' they provide high humidity to the own climate.  Literally, the Redwood Forest maintains its own climate due to its storage and use of water vapor.

The same is true in Montain Forests or Cloud Forests.  They create and maintain their own climate through their use of water vapor.

In the case of Texas the drought has created a very dry climate for the region.  That dry climate simply reinforces itself due to lack of 'climate systems' that provide their own climate and the surrounding region.

Those two images are a full one week apart, yet it is profoundly simple to realize why they are so strongly related.
