Dangerously Excessive Heat and Humidity Continues from the Midwest and Eastward

Oppressive heat and humidity will continue through Saturday from the Midwest to the East Coast. The Midwest will get a slight reprieve on Sunday as a cold front moves through the area, while excessive heat continues in the East. In addition, strong to severe storms will bring potential for damaging winds, hail, and heavy rain on Saturday. 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.
