Comments:
While this particular storm did not give us much in the way of rainfall, only a trace amount, the area did see a very large dust storm. At times during the storm, at our location, the visibility dropped below 500 feet. This dust storm was generated by a severe thunderstorm which created a downburst near Williams Gateway Airport. The peak wind gust at Williams Gateway was 86mph, with reports of planes flipped over. As a result of the low visibility and other reports, we will rate this storm in the Significant category. Even though the storm was in the Severe category southwest of the area, we are not rating it Severe because at our location we did not meet any of the Severe Thunderstorm criteria.
