802 FXUS64 KSHV 100504 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1204 AM CDT Thu Jul 10 2025 ...New DISCUSSION, SPOTTER INFORMATION STATEMENT... .KEY MESSAGES... Issued at 1159 PM CDT Wed Jul 9 2025 - One more day of scattered to numerous daytime showers and thunderstorms today, mainly across our southern and eastern areas. - Rain chances diminish for Friday through the upcoming weekend. - Temperatures will continue to climb into early next week with critical heat indices possible and the return of Heat Advisories next week. && .DISCUSSION... Issued at 1159 PM CDT Wed Jul 9 2025 Should see one more day of increased diurnally driven convection today with the key ingredients being an upper level shear axis emanating from the Tenn Valley, south and west into SE TX and plentiful moisture in the form of higher PWATs. This abundant moisture shifted a little further south and east on Wednesday, thus areas virtually void of convection near and northwest of the I-30 Corridor. Latest mesoanalysis showing PWATs aoa 1.5 inches are present across the southern half of NE TX, into all of N LA and into far S and SE AR. Extrapolating that out, it would make sense that the greatest convective coverage today should be across our far southern, southeast and eastern zones. This is mostly in agreement with latest NBM output but more so with the latest HREF as it has handled convective coverage quite well the last couple days with the above mentioned parameters. Thus, pop distribution will range from isolated coverage along and near the I-30 Corridor to low end likely coverage across our SE zones. As has been the case the last several days, have held onto small pops beyond 00z this evening as the NBM wants to diminish convection too quickly after sunset. Drier air pushes into our western 2/3rds for Friday even through a weakened upper level shear axis remains in place so have limited pops to low end chance variety only across our eastern third with slight chance pops as far west as along a Lufkin, Shreveport, Prescott line. Did not make any changes to NBM temps as it has a pretty good handle on tempered values where pops are highest today across our southeast zones with a noticeable rise across most all areas with diminished convection for Friday. For the upcoming weekend and into next week, upper ridging across the far eastern Gulf of America appears to be expanding and/or retrograding westward for late Saturday into Sunday. This should push our present shear axis north and west as well but there will be pockets of higher pwat across our northern and southern zones to warrant isolated to scattered pops across our region both days. As we begin the upcoming work week, the center of a dirty upper level ridge will be parked across the Lower Miss Valley into the Tenn Valley but the word dirty will best describe this feature as there will be available moisture present for the possibility of at least isolated to scattered diurnally driven convection through at least the middle part of next week. Given the proximity of the upper level ridge, temperatures should respond accordingly with temperatures near triple digits across some locations if not by Monday, then definitely by Tue into Wed of next week. That means a return to the likelihood of Heat Advisories as critical heat indices will likely be met. 13 && .AVIATION... (00Z TAFS) Issued at 808 PM CDT Wed Jul 9 2025 For the 10/00Z TAF period, scattered sea breeze convection earlier this afternoon has induced additional outflow boundaries along the I-20 corridor this evening. As a result, more northward movement of this convection is possible over the next few hours before it gradually diminishes with the loss of daytime heating. Otherwise, VFR conditions are expected to prevail and expect less convection overall on Thursday compared to today but have inserted VCTS at KSHV/KMLU/KLFK terminals late in the TAF period with another round of diurnally driven sea breeze convection possible across our more southern and eastern airspace. S/SW winds should generally prevail between 4-8 kts on average with higher gusts invof convection. /19/ && .SPOTTER INFORMATION STATEMENT... Issued at 1159 PM CDT Wed Jul 9 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...
