Heat in Claiborne, Louisiana

An upper level ridge of high pressure over the Southeast United States began to retrograde west across the Lower Mississippi Valley into the Four State Region during the final several days of July, resulting in the return of much hotter temperatures as they climbed back into the mid 90s to near 100 degrees. While dewpoints were able to mix out to some extent, resultant heat indices still ranged from 105 to 110 degrees from the 27th through the 29th. However, more widespread triple digit temperatures were observed on the 30th, and dewpoints were unable to mix out much through the day, resulting in more oppressively hot conditions with heat indices ranging from 110-117 degrees to end July.
