Volume 16 Number 10                                                                                            OCTOBER 2003

Severe weather characterized the beginning of October in Texas.  On the 5th a stationary front created instability in the atmosphere which triggered showers and thunderstorms.  The High Plains region of Texas experienced one tornado, numerous large hail reports up to 2.75 inches in diameter, and high winds.  The Eastern region of Texas, including the Bryan/College Station area reportedly experienced damage from a weak tornado on the 5th as well.  As the stationary front lingered, large hail reports were also noted on the 6th in the High Plains.  A waterspout associated with a rain shower moved on shore and into Harris County on the 8th and was reported as a tornado with little damage.  An additional front and low-pressure disturbance caused unstable conditions in the Houston area on the 9th, with six reports of tornadoes. 

 

Austin, San Antonio, and Victoria were the only cities to report below normal mean temperatures with -1.6, -0.1, -0.4 degrees Fahrenheit below normal respectively.   Precipitation was above normal in half of the first-order stations, and below normal in the other half.  North of a line from El Paso to Dallas/Fort Worth experienced below normal precipitation.  The Southern half of the state with the exception of a small area including Austin and San Antonio, received above normal precipitation for the month of October. Copious precipitation fell in Port Arthur with 9.58 inches, which is 205% of the normal expected monthly rainfall.  Brownsville, and College Station reaped the benefits of numerous stationary fronts with rainfall totals of 6.89, and 6.82 inches respectively.

 

The month of October came to a close with above normal temperatures and little precipitation.
