Critical Fire Weather Concerns; Storm Tracking Across the Plains

Combination of strong winds, dry conditions and above normal temperatures will result in elevated to critical fire weather concerns for the Southern Plains and portions of Southern California. This is part of a storm system that is tracking across the central Plains with occasional snow showers and heavier snow from the Rockies through the Central/Northern Plains. 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.
