SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0111 PM CST Fri Jan 09 2026 Valid 111200Z - 121200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected across the U.S. on Sunday. ...Discussion... An amplified midlevel trough will advance eastward across the Northeast and Mid-Atlantic through the period. Strong forcing for ascent and steepening deep-layer lapse rates preceding the trough could result in an isolated lightning flash with low-topped convection overspreading the Mid-Atlantic. However, low confidence in this scenario and expected limited coverage precludes a TSTM area at this time. Upstream, an expansive cool/dry air mass will limit thunderstorm potential across the CONUS. ..Weinman.. 01/09/2026
