A large upper level ridge of high pressure was anchored over Southcentral Texas into the Lower Mississippi and Tennessee Vallies July 9th and 10th, resulting in an expansive area of sinking air which allowed for afternoon temperatures to climb into the mid 90s each day. Little mixing of dewpoints occurred during this time, with the resultant heat indices ranging from 105-110 degrees across North Louisiana. A weak cool front and associated upper level shortwave trough moved through the area during the afternoon hours on the 11th, but the slightly cooler air and lower humidities were not able to mix south through the region until the evening hours through the morning on the 12th. Thus, afternoon temperatures across North Louisiana on July 11th again rose into the mid 90s, with the resultant heat indices ranging from 105-109 degrees.
