SPC Nov 14, 2021 0600 UTC Day 1 Convective Outlook

SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1119 PM CST Sat Nov 13 2021 Valid 141200Z - 151200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast across the CONUS today. ...Discussion... Well-defined upper vort over MN is digging southeast as 500mb speed max is expected to translate from the central Plains into the TN Valley by late afternoon. Associated surface low/cold front will cross into southwestern lower MI by 18z then advance into southern ON by early evening. Strong cold advection across LM on the back side of this feature will encourage lake convection as profiles cool and lapse rates steepen. At this time it appears most of the lake-induced convection will remain too shallow/weak to warrant thunderstorm probabilities this period. ..Darrow.. 11/14/2021 Read more LIVE:
