024 FXUS64 KSHV 190828 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 328 AM CDT Thu Sep 19 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Thursday through Friday) Issued at 231 AM CDT Thu Sep 19 2024 Mostly clear skies and light winds have settled across the region this morning under upper-level ridging. Short-term progs suggest that fog will form again over the next several hours, then diminish a couple hours after daybreak. No widespread dense fog is expected, but we will monitor this closely. With upper ridging established over the region over the next couple of days, quiet conditions will continue, but we will see above normal temperatures. Afternoon highs will climb into the mid 90s under partly cloudy skies. Despite the above normal temps, heat index values should remain a few degrees below the 105 degree Heat Advisory criteria. /20/ && .LONG TERM... (Friday Night through Thursday) Issued at 231 AM CDT Thu Sep 19 2024 Upper ridging will remain in place over the weekend, along with the quiet and above normal temperatures. Afternoon highs will once again climb into the mid 90s, with overnight lows remaining in the upper 60s to lower 70s. Despite the above normal temperatures, heat index values should still remain just below the 105 degree Heat Advisory criteria. By the first of next week, the ridge will flatten out and start to shift eastward, as an approaching longwave trough moves into the Southern Plains out of the Rockies. Long-range progs are now suggesting the trough could make it into our extreme northern sections as early as Monday, just north of the Interstate 30 corridor. This would result in rain chances across portions of Southeast Oklahoma and adjacent Southwest Arkansas. The trough and associated cool front is expected to push into the region, bringing a return in widespread rain chances, as it stalls across the area on Tuesday and Wednesday. As of now, dry conditions look to return by next Thursday, as the frontal boundary finally pushes east of the region. /20/ && .AVIATION... (06Z TAFS) Issued at 1155 PM CDT Wed Sep 18 2024 Prevailing SKC to begin the 06z TAF package. Can`t rule out some areas of fog towards sunrise, especially in the vicinity of the LFK, ELD and MLU terminals but it should be brief, if at all. Otherwise look for a developing cu field today with some high thin cirrus increasing across our airspace as well. VFR conditions will prevail into the late evening hours tonight. Look for mostly variable to SE winds today with speeds under 10kts. 13 && .PRELIMINARY POINT TEMPS/POPS...
