SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0124 AM CDT Sun Apr 15 2018 Valid 171200Z - 181200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few thunderstorms are possible from the central Rockies into Iowa Tuesday. ...Discussion... Strong mid-level speed max will translate across the lower CO River Valley into KS Tuesday night. In response to this feature a surface low will develop in the lee of the central Rockies then track into southwest IA by 18/12z. Cold mid-level temperatures/steep lapse rates are expected to spread across CO into IA which should result in weak instability north of the aforementioned speed max. While moisture will be somewhat limited ahead of the short wave, it appears weak convection/isolated lightning should develop north of the low track where warm advection will aid UVV. ..Darrow.. 04/15/2018 Read more
