SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0117 PM CST Sun Nov 02 2025 Valid 041200Z - 051200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm and severe potential are low Tuesday. ...Synopsis... Broad troughing over the eastern US is forecast to weaken and shift into the Atlantic Tuesday ahead of a deepening Pacific trough approaching the West Coast early Wednesday. Persistent ridging over the Southwest will favor strong but largely zonal mid-level flow over much of the central CONUS. A dry and cool airmass is expected with surface high pressure over the Southwest and Southeastern US the primary feature. As a result, large-scale subsidence and continued dry offshore flow will suppress buoyancy and thunderstorm development over much of the country. The only exception to this may be near the OR/northern CA Coasts into early Wednesday morning. Here, cool mid-level temperatures and onshore flow could support a sporadic thunderstorm in the early morning hours ahead of a strong cold front expected to move onshore Wednesday. ..Lyons.. 11/02/2025
