374 FXUS64 KSHV 060544 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1244 AM CDT Sat Jul 6 2024 ...New AVIATION... .UPDATE... Issued at 755 PM CDT Fri Jul 5 2024 Adjust pops/wx/add fog for tonight and remove the heat headline. && .SHORT TERM... (Tonight through Sunday Night) Issued at 755 PM CDT Fri Jul 5 2024 The cold front is dropping down well in the wake of all our wonderful heat dispersing rainfall. Radar coverage remains most active now across our southern tier of Co/Pa and will remain so for a couple more hours while diminishing along the way with sunset. Still some activity possible overnight so no major changes there, just needed to sweep back across McCurtain for a couple more hours. This is where we are seeing mid 60 dew points near I-30 with low to mid 70s, or more with this rainfall. Air temps are rain cooled mid to upper 70s and low 80s. We are seeing NE winds now into E TX, as if this afternoon we had the front door push and now it`s backdooring down. So again, this front will sag in our I-20 corridor overnight and we may see some patchy fog in the predawn and post dawn hours in the warm sector. Northerly winds should keep a drying trend north of I-20 for the short run in that regard. /24/ && .LONG TERM... (Sunday through next Thursday) Issued at 304 PM CDT Fri Jul 5 2024 Sunday morning will see a renewed round of showers and storms move into the ArkLaTex, with precip chances continuing throughout the course of the day. By this point, the upper level pattern will be somewhat in flux, with the high off to our east over the Florida peninsula, the trough responsible for the boundary forcing this new moisture to the north over the Plains and Midwest, and of course Beryl in the Gulf of Mexico, which looks to be returning to hurricane strength by this time as is treks northwest towards the Texas coastline. The bottom line for the ArkLaTex is that we are closely monitoring Beryl, as the latest model runs suggest it will arc to the northeast upon its landfall, bringing impacts to the ArkLaTex early next week, likely beginning late Monday into Tuesday depending on the extent of the rain field. When combined with the existing moisture in the form of convection being stirred up by our stationary boundary, this will bring with it the possibility of flash flooding across much of the Four State Region, especially east Texas and into north Louisiana and southern Arkansas, with the ERO for Tuesday featuring a Slight Risk including the aforementioned regions, and further upgrades are not being ruled out as of this writing. Depending on the structure, organization and coverage expanse of Beryl as it treks northeastward, severe weather impacts to the ArkLaTex are not out of the realm of possibility. However, there are too many variables at this time to say much beyond that we will be closely monitoring the development of this tropical system. The nature of Beryl`s interactions with the upper level troughing will be of enormous consequence for the latter days of this extended forecast. In broad strokes, it seems reasonable at this point to anticipate a breakdown in the TC`s organization as it gets absorbed into the trough. This troughing looks to remain very much in place due north as ridging over the Intermountain West and ridging over the Atlantic coast help hold it in place, continuing to deluge the ArkLaTex with daily chances for showers and storms through next week. Temperatures will remain seasonable throughout if not below average, with highs in the lower 90s possible only climbing into the upper 80s by the middle of next week, while lows remain in the upper 60s to middle 70s. /26/ && .AVIATION... (06Z TAFS) Issued at 1238 AM CDT Sat Jul 6 2024 With the exception of tempo MVFR ceilings across some sites near daybreak, mainly VFR conditions to prevail across area terminals through the TAF period ending 07/06Z. VCTS conditions may be possible near MLU this afternoon. Otherwise, light southeast winds tonight to become northeast around 4 to 7 knots on Saturday behind a weak frontal boundary that will push through the region from the north. Light and variable winds expected after 07/00Z. /05/ && .PRELIMINARY POINT TEMPS/POPS...
