Winter Weather of February 23, 2010 across East Texas
A late-season winter storm affected portions of East Texas and Northwest Louisiana which began in the late morning and lasted through the evening of Tuesday February 23, 2010. Cold arctic air filtered into the region late Monday and early Tuesday ahead of an upper level disturbance moving out of the southwestern United States. The upper disturbance was weakening as it progressed east and was eventually phased into a larger scale upper level trof over the eastern United states. However,before it weakened significantly, there was enough lift and moisture to dump up to 4" of snow across portions of Cherokee County and northern Nacogdoches County Texas. Temperatures started the day in the mid to upper 30's across the region but slowly fell as evaporative cooling and snow falling into the warmer air cooled the lowest 1000 feet of atmosphere. Other areas in Smith, Rusk, Gregg, and Angelina Counties reported anywhere from 1-3" of snow which quickly melted due to warmer ground temperatures. Numerous accidents were reported where the heaviest snow occurred in Cherokee and Nacogdoches counties as well as several in the Tyler area.
Locations in Northwest Louisiana warmed too quickly into the lower 40's during the day Tuesday and the evaporative cooling process was not enough to cool many locations to a level which would support the amounts of snow which occurred across East Texas. However, light snow and snow flurries occured and some trace amounts of snow were reported in the Shreveport area as well as in Natchitoches Louisiana.

A still shot of the radar image over surface temperatures on Tuesday at 9:30 AM shows most of east Texas is breaking out in snow or a snow/rain mix.
The rain/snow line wavered during the day but stayed primarily over deep east Texas. Areas in Louisiana stayed primarily rain but eventually things changed to snow
for the final 2-3 hours of the event.
