SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0632 PM CST Sun Dec 14 2025 Valid 150100Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected tonight. ...01z Update... Northwesterly flow is deepening across the southern FL Peninsula as the primary synoptic front surges toward the FL Straits. Isolated showers are lingering across this region, with even a few flashes of lightning near West Palm Beach. However, this activity should continue to wane then focus well offshore over the next few hours. 00z sounding from UIL is quite stable this evening with poor lapse rates noted through 6km. Late tonight elevated buoyancy may increase near the WA coast such that weak convection is able to develop ahead of approaching short-wave trough. If lightning is noted with this activity it will remain quite sparse. ..Darrow.. 12/15/2025
