SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0105 PM CST Sat Jan 17 2026 Valid 191200Z - 201200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Monday. ...Synopsis... Thunderstorm potential appears negligible across the country for Monday. An extensive cold/dry continental air mass and building surface high pressure over the central CONUS will promote dry conditions for most regions east of the Rockies. Broad-scale upper ridging will persist along the West Coast, maintaining low chances for precipitation. A lightning flash or two appears plausible on the eastern shores of the lower Great Lakes where cold 850-700 mb temperatures may support mixed-phase hydrometeors within deep lake-effect snow bands. However, this potential seems too spatially limited and conditional to warrant broader 10% thunder probabilities at this time. ..Moore.. 01/17/2026
