600 FXUS64 KSHV 091130 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 630 AM CDT Wed Jul 9 2025 ...New AVIATION... .KEY MESSAGES... Issued at 1154 PM CDT Tue Jul 8 2025 - Scattered to numerous showers and thunderstorms will once again be possible with the aid of daytime heating today. - Isolated storms could produce damaging wind gusts and excessive heavy rainfall. - Upper ridge setting up across the Lower Mississippi Valley could result in Heat Advisory headlines by the end of the 7-day forecast. && .DISCUSSION... Issued at 1154 PM CDT Tue Jul 8 2025 Still dealing with scattered showers and an isolated thunderstorm or two...mainly near and north of the I-20 Corridor late this evening. This activity should continue dissipating but we will likely keep at least isolated storms around through at least sunrise near the I-20 Corridor due to an inverted upper trough that remains entrenched across our region. This feature is wedged between high pressure off the eastern seaboard and upper ridging across the Four Corners Region of the Country. High PWATS upwards of 2 inches remains firmly entrenched across our region as well so all we need is some diurnal heating and you have the necessary ingredients for scattered to numerous showers and thunderstorms once again for today into the evening hours tonight. The greatest coverage area appears to be near and south and east of the I-30 Corridor Today through this evening as this is where the highest PWAT should reside. These ingredients shift every so slowly eastward for Thursday and thus, the highest pops Thu/Thu Evng should reside across the east and southeast half of our region. By Friday, the remnant shortwave trough should have diminished to little more than a weak shear axis across our region with drier air beginning to infiltrate our region from the west. This will result in a reduction in pop coverage with pops delegated to our far eastern and southern zones only for Friday. Temperatures should be tapered somewhat today by precipitation chances but not to the extreme the NBM suggests. Slightly lesser storm coverage on Thursday and especially on Friday means hotter temperatures with highs by Friday ranging in the middle to upper 90s areawide. For the upcoming weekend, we should begin to see an increase in PWAT from the south and this combined with our weak shear axis in place should result in at least isolated to scattered diurnally driven storm coverage across our region through at least Sunday. Did not stray from NBM pops or temps through the weekend despite upper ridging beginning to retrograde from the Southeast U.S. on Saturday into the Lower Miss Valley by late Sunday. This feature should begin to setup across the heart of our region by early next week which will likely result in critical heat indices and the possible return to Heat Advisory criteria to start the next work week. 13 && .AVIATION... (12Z TAFS) Issued at 619 AM CDT Wed Jul 9 2025 For the 09/12Z TAF update, VFR vis/cigs are expected to prevail through most of the period. VCTS will return from 08/18Z to 09/00Z across the southern airspace as southerly winds slacken by the end of the period. /16/ && .SPOTTER INFORMATION STATEMENT... Issued at 1154 PM CDT Tue Jul 8 2025 Spotter activation is not likely today through tonight as widespread damaging wind gusts are not forecast. However, an isolated storm or two could reach severe limits producing damaging wind gusts and excessive heavy rainfall that could result in area flooding. 13 && .PRELIMINARY POINT TEMPS/POPS...
