Hazardous Weather Outlook National Weather Service Shreveport LA 1134 AM CDT Thu Jul 5 2018 LAZ017>020-022-TXZ149-152-153-165>167-061100- Sabine-Natchitoches-Winn-Grant-La Salle-Cherokee-Nacogdoches- Shelby-Angelina-San Augustine- 1134 AM CDT Thu Jul 5 2018 This Hazardous Weather Outlook is for portions of north central Louisiana, northwest Louisiana, east Texas and northeast Texas. .DAY ONE...This afternoon and Tonight... A deep easterly flow will persist across the area with embedded troughs of low pressure in the tropical easterlies over the Northeast Gulf of Mexico. Ascent with this wave will combine with strong diurnal heating of a very moist atmosphere, weakly capped environment to allow numerous showers and thunderstorms. Given the expected degree of instability and deep layer shear, thunderstorms are expected to organize into multicell clusters posing a marginal risk for wet micro-bursts this afternoon and evening. A modestly more substantive damaging wind threat will be possible with any west moving multicell cluster that can grow upscale into small bowing segments. Strong and damaging winds along with locally heavy rainfall and deadly lightning will be the main threats. These storms will gradually diminish late this evening with the loss of heating. In addition, afternoon temperatures will climb into the mid and possibly upper 90s. When combined with the humidity, afternoon heat indices will range from 100 to 105 degrees. While outside, remember to take frequent breaks in the shade and drink plenty of water. .DAYS TWO THROUGH SEVEN...Friday through Wednesday... Isolated to widely scattered showers and thunderstorms will be possible areawide Friday afternoon, although rain chances may begin to increase Friday night through this weekend into early next week as a weak surface front drifts South into the region and possibly stalls out over East Texas and Northern or Central Louisiana. Isolated strong to severe storms will be possible, with damaging winds and brief heavy rainfall. These unsettled conditions look to continue through mid week when an upper level ridge of high pressure builds back to the Southwest into the region. Afternoon temperatures will also climb into the mid and possibly upper 90s Friday, with resulting heat indices ranging between 100 to 105 degrees. However, with the increased cloud cover and scattered showers and thunderstorms, temperatures should fall into the upper 80s and lower 90s this weekend through early next week. .SPOTTER INFORMATION STATEMENT... Activation of emergency managers, amateur radio operators, and storm spotters, may be needed during the afternoon and evening. ARZ050-051-059>061-070>073-LAZ001>006-010>014-021-OKZ077-TXZ096- 097-108>112-124>126-136>138-150-151-061100- Sevier-Howard-Little River-Hempstead-Nevada-Miller-Lafayette- Columbia-Union-Caddo-Bossier-Webster-Claiborne-Lincoln-De Soto- Red River-Bienville-Jackson-Ouachita-Caldwell-McCurtain-Bowie- Franklin-Titus-Camp-Morris-Cass-Wood-Upshur-Marion-Smith-Gregg- Harrison-Rusk-Panola- 1134 AM CDT Thu Jul 5 2018 This Hazardous Weather Outlook is for portions of south central Arkansas, southwest Arkansas, north central Louisiana, northwest Louisiana, southeast Oklahoma and northeast Texas. .DAY ONE...Today and Tonight... Isolated to scattered showers and thunderstorms will develop this afternoon across much of the region, as a weak upper level disturbance drifts west across Arkansas and Southeast Oklahoma. In the west moving convection there will be a chance of storms becoming strong to isolated severe with damaging winds, locally heavy rainfall and deadly lightning. In addition, afternoon temperatures will climb into the mid and possibly upper 90s. When combined with the humidity, afternoon heat indices will range from 100 to 105 degrees. While outside, remember to take frequent breaks in the shade and drink plenty of water. .DAYS TWO THROUGH SEVEN...Friday through Wednesday... Isolated to widely scattered showers and thunderstorms will be possible areawide Friday afternoon, although rain chances may begin to increase Friday night through this weekend into early next week as a weak surface front drifts South into the region and possibly stalls out over East Texas and Northern or Central Louisiana. Isolated strong to severe storms will be possible, with damaging winds and brief heavy rainfall. These unsettled conditions look to continue through mid week when an upper level ridge of high pressure builds back to the Southwest into the region. Afternoon temperatures will also climb into the mid and possibly upper 90s Friday, with resulting heat indices again ranging between 100 to 105 degrees. However, with the increased cloud cover and scattered showers and thunderstorms, temperatures should fall into the upper 80s and lower 90s this weekend through early next week. .SPOTTER INFORMATION STATEMENT... Activation of emergency managers, amateur radio operators, and storm spotters, should not be needed through tonight. 06
