A Heat Advisory is in effect today for all of the Four State Region. Temperatures will again climb into the mid and upper 90s this afternoon across the area, and when combined with the humidity, will result in heat indices ranging from 105 to 110 degrees. In addition, isolated to widely scattered showers and thunderstorms will develop today over portions of East Texas and North Louisiana, before diminishing by sunset. .DAYS TWO THROUGH SEVEN...Friday through Wednesday... Very hot, humid, and mostly dry conditions will continue across the region Friday through Sunday, as an upper level ridge of high pressure begins to shift southeast into the area. This will result in the hottest temperatures so far this summer, and when combined with the humidity, will produce heat indices that will near or exceed 105 degrees each day. However, a weak cool front will shift south into the region late Sunday, which will focus an increase in showers and thunderstorms over the area late Sunday through Tuesday. The increased cloud cover and rain near and behind the front will also contribute to slightly cooler temperatures Monday through midweek. .SPOTTER INFORMATION STATEMENT... Activation of emergency management personnel...amateur radio operators...and storm spotters will not be needed through tonight. 15
