551 ACUS48 KWNS 190753 SWOD48 SPC AC 190752 Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0252 AM CDT Sat Apr 19 2025 Valid 221200Z - 271200Z ...DISCUSSION... ...Days 4-6/Tue-Thu -- Southern Plains... A low-amplitude west/southwesterly mid/upper flow pattern will prevail Days 4-6/Tue-Thu. South/southeasterly low-level flow across the western Gulf into the southern Plains will allow for northward moisture transport and daily diurnal destabilization. In the absence of any stronger shortwave troughs moving through the weak west/southwesterly flow regime, severe potential is uncertain and will likely be driven by mesoscale/local processes, precluding 15 percent probabilities at this time. ..Leitman.. 04/19/2025
