Dramatically lower temperatures are expected to follow a cold front moving into the area this weekend, but dry conditions prompted both Henderson and Kaufman Counties officials to continue with existing burn bans. Henderson County officials extended its burn ban for 14 days on Sept. 4. Kaufman County officials rejected a motion to drop the burn ban on Aug. 27, extending it until at least Sept. 10. Residents in both counties are prohibited from outdoor burning to include trash and burn barrels. The burn ban does not prohibit burning related to public health and safety authorized by the Texas Commission on Environmental Quality for firefighter training, public utilities operations and agricultural planting and harvesting activities. Violation of the burn bans is a Class C Misdemeanor and can result in up to $500 fines. County officials noted that the rainfall seen during the past couple of weeks had not improved conditions sufficiently. Weeks of 100-degree-plus weather has left fields dry and combustible. Temperatures are expected to drop into the 80s during the day and into the 60s during the night by Saturday. Significant rainfall is not expected to accompany the cold front, which is expected to move into the the Houston area within a couple of days. Weather forecasters report that a return of 100-degree weather in North Texas is unlikely until next summer. Public health officials are reminding people who plan to venture outside in the cooler weather to remember the threat of mosquito bites and the West Nile Virus. Mosquito repellent still needs to be applied to ward off the insects.
