488 FXUS64 KSHV 160857 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 357 AM CDT Fri Aug 16 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Friday through Saturday) Issued at 356 AM CDT Fri Aug 16 2024 Dangerous heat will continue across the Four State Region through the weekend with little relief expected. This is due to ridging aloft that will persist through Saturday, keeping southerly winds below 10 mph and dew points in the muggy 70s. The little relief that is set to fully arrive will show up in the form of isolated showers and thunderstorms (10-20% chance) across central Louisiana parishes this afternoon and tomorrow afternoon. Otherwise, a slowly approaching frontal boundary will boost compressional heating and temperature maximums into the lower 100s today and tomorrow which, in combination with high dew points, will continue Excessive Heat Warning conditions across more of the area. Overnight temperature minimums in the upper 70s/lower 80s will also offer little in the way of relief. Heat hazard products are almost fully certain to continue to be issued through this weekend with dangerous, prolonged heat contributing to cumulative heat stress. Adequate precautions and awareness are encouraged now against the elevated potential for heat illnesses. This includes (and is not limited to) altering outdoor plans, taking frequent breaks if you must be outside, checking the backseat of your vehicle, and knowing the signs and symptoms of heat exhaustion and heat stroke. /16/ && .LONG TERM... (Saturday Night through Friday) Issued at 356 AM CDT Fri Aug 16 2024 A reprieve is finally on the horizon for the Four State Region as a frontal boundary arrives early next week. This will allow for winds out of the north to arrive on Monday that will gradually push the 70-degree isodrosotherm back west into Texas, introducing dew points in the 60s and temperature maximums in the mid-to-upper 90s (near normal for this time of the year). That said, long range guidance continues to paint a dry picture with Day 1-7 QPF totals still at or below 0.25-inch areawide. /16/ && .AVIATION... (06Z TAFS) Issued at 1233 AM CDT Fri Aug 16 2024 An upper-level ridge across the region will maintain dry conditions across area terminals through the forecast period ending 17/06Z. The only exception could be a stray shower or thunderstorms that emerges during the heat of the day. At this time, however, coverage is too low to mention in the terminals. Otherwise, VFR conditions to prevail with light southwest winds this morning increasing to near 8 knots this afternoon and becoming south under 5 knots after 17/00Z. /05/ && .PRELIMINARY POINT TEMPS/POPS...
