Texas Climate Report: May 2008

The month of May was relatively dry for most of the western and southern portions of Texas, as well as for most of central Texas. Notably dry cities include Galveston, Victoria, and El Paso, which received 1%, 6%, and 8% of the normal precipitation for the month, respectively. Eastern Texas and the Panhandle enjoyed more rainfall, though most cities did not reach their normal average precipitation for the month. Temperatures across the state ran above average, generally from 1°F-4°F above average. Central Texas was most affected by this rise in temperature, while the temperatures along the coast, though slightly warmer than normal, were moderated by the sea.

Temperatures steadied to above average levels during the second half of the month. Of course, several cases of severe weather were observed this month; with respect to severe weather, this year has been certainly above average in activity.
