695 FXUS64 KSHV 311850 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 150 PM CDT Thu Jul 31 2025 ...New DISCUSSION... .KEY MESSAGES... Issued at 159 PM CDT Wed Jul 30 2025 - The Extreme Heat Warning/Heat Advisory both remain in effect until 7PM this evening. Expectation is for a Heat Advisory along and south of I-20 for Friday afternoon to be issued in our overnight zone package. - Scattered to numerous showers and thunderstorms are expected across much of the Four-State area tonight and "Some may be Heavy" on Friday and Friday night with slow movement along the cold front. Per coordination with WPC, some of NE TX will have a Slight Excessive Risk Outlook through Friday and overnight. - The cold front remains on track with drier air from the NE during the mid to late day north of I-20 and then dropping southward Friday evening and overnight. So we are still looking good to be able to part with the heat headlines this weekend. && .DISCUSSION... Issued at 1241 PM CDT Thu Jul 31 2025 Cool pool formation is well underway with thunderstorms clustering in central Arkansas and expanding southwestward. The cold front lies just to the north and will have much work done in the wake of this activity. Meanwhile, the heat today has been here and there with lots of AC and cirrus early, but lots of sunshine is now looming for the remainder of this afternoon. And still perhaps some compressional heating ahead of the cold front to spike calculations through the late afternoon hours. The SPC day one outlook has a Marginal Risk for severe with wind damage the primary threat with this approaching cluster and rain cooled air crashing down into the hot air near surface. As per key messages, the WPC is planning for a small Slight Risk ERO for NE TX tomorrow day and night. While not widespread enough for a Flood Watch, we may see an isolated warning or at least some flood advisory criteria with the likely pops and the slow movement of storms expected to persist. The cold front looks to spread around even more upper 80s on Saturday as clouds will linger with the refreshing NE winds. Sunday morning looks to be a nice day with mid to upper 60s north and low 70s across our southern tier of Co/Pa. The air temps remain below average for a couple of days and then ease back to average and above b mid to late work/school week. The chance for rainfall will linger beyond the weekend, as tropical moisture and the associated easterly wave propagation underneath, run along the boundary of the midWest 1029mb air mass sprawling all the way down across I-20 for days. Modification of the air mass is always a truth apart from it`s continental source region. However, the push into August is already looking up with a secondary air mass of 1020+mb during next weekend. /24/ && .AVIATION... (12Z TAFS) Issued at 559 AM CDT Thu Jul 31 2025 Starting to see isolated convection early this afternoon across portions of Southwest Arkansas and Deep East Texas. This convection should continue to develop and could impact most any terminal across our airspace through 03z this evening. Have therefore prevailed VCTS at all terminals beginning at 20-21z this evening. Model time/height cross sections support the possibility of MVFR ceilings near and north of the I-20 Corridor late tonight just before sunrise and continuing through the end of the 18z TAF period on Friday so did add this mention as well. Otherwise outside of convection, look for VFR conditions to prevail, at least until the predawn hours Friday Morning. 13 && .SPOTTER INFORMATION STATEMENT...
