Hazardous Weather Outlook: Heat Indices Range 100-105 degrees

July 2, 2018 - The National Weather Service Shreveport, LA issues a Hazardous Weather Outlook at 10:37am CDT Monday, July 2, 2018.

This Hazardous Weather Outlook is for portions of northwest Louisiana, east Texas and northeast Texas - De Soto, Sabine, Wood, Upshur, Marion, Smith, Gregg, Harrison, Cherokee, Rusk, Panola, Nacogdoches, Shelby, Angelina, San Augustine

Today and Tonight... An upper level ridge of high pressure will remain anchored over much of the area today. As a result, temperatures will climb into the upper 90s to near 100 degrees this afternoon. When combined with the humidity, heat indices will range from 100 to 105 degrees once again. If you must be outside, remember to take frequent breaks and drink plenty of water.

Tuesday through Sunday... An upper level disturbance will drift west across the Lower Mississippi Valley and into Southern Arkansas and much of Louisiana Tuesday, which should help initiate scattered to numerous showers and thunderstorms over much of the region. However, one more day of very hot temperatures is expected especially over East Texas, Southeast Oklahoma, portions of Southwest Arkansas and Northwest Louisiana, as temperatures again climb into the upper 90s, and resultant heat indices range between 100 and 105 degrees. These scattered showers and thunderstorms will persist Tuesday night and Wednesday over much of the region as this disturbance continues to drift west across the area. Brief heavy rainfall and locally gusty winds will be possible in the stronger storms. While these storms may become more isolated Thursday, scattered showers and thunderstorms should increase Friday through Sunday, ahead of a potential series of upper level disturbances that will again shift west across the region.
