First Dust Storm of the Season Strikes |
A Southwest jet prepares to depart to Austin amid blowing dust at Lubbock International Airport on Saturday afternoon (16 November 2013). This was near the height of the wind when gusts were near 50 mph. The visibility dropped as 1.25 miles during the height of the dust storm. |
The wind and dust season kicked off on Saturday for the South Plains region. A strong storm system passing by to the north of the area was responsible for the winds, bringing gusty winds to much of the central and western portion of the nation. Here in northwest Texas winds during the afternoon gusted into the 45-55 mph range. These winds lofted plenty of blowing dust, especially in a corridor from near Plains to Lubbock to Floydada and Childress, as illustrated in the below satellite image. The visibility dropped to near 1 mile during the peak of the dust storm at the Lubbock and Childress airports. Conditions quickly improved near sunset when winds decreased and dust began to settle out. |

The below image shows the maximum winds observed during the afternoon hours of November 16th. The plume of dust (above) corresponded to a corridor of stronger wind gusts that moved across the central South Plains. Additional wind gusts in excess of 50 mph were also observed over portions of the central and western Texas Panhandle. In Dalhart a peak gust of 62 mph was recorded. |

Although skies were mostly clear during the afternoon, the dust did filter the sunshine (insolation). Even though this decreased the amount of heating from the sun (see the below graph), the stout southwesterly downslope winds still propelled temperatures well into the 70s, with highs off the Caprock topping out in the lower 80s. |
