Severe Weather and Heavy Rainfall from the High Plains to the Ohio Valley; Heat Continuing in the Central Plains and Southeast

A stationary front will be the focus for daily showers and thunderstorms capable of widely scattered flash flooding and severe weather from the High Plains to the Ohio Valley. Monsoonal thunderstorms could cause local flash flooding across the Southwest and the Great Basin. Dangerous heat continues across the Central Plains and Southeast. Many areas will see their hottest temperatures of the year. Read More >

Heavy Snow Event 

March 6, 2008

   

 

On 6 March 2008, a convective precipitation band formed across North Texas and quickly transitioned from rain to snow in a 60 km wide zone extending from west of the Dallas / Fort Worth metroplex northeast into extreme North Texas near the Red River. The snow persisted for over three hours with accumulations averaging 7 cm and isolated reports up to 30 cm near the heaviest convective precipitation. Frontogenesis and the resulting ageostrophic circulation appeared to play key roles in not only providing significant forcing for ascent but also in modifying the vertical temperature profile to be supportive of a liquid-to-frozen precipitation transition.  The presence of atmospheric instability led to isolated thunderstorm development, with occasional cloud-to-ground and in-cloud lightning observed in the band of heavy snow. This study reviews the complex interactions between moisture, instability, and forcing for ascent that occurred during this convective winter weather event.
