SPC AC 190040 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0740 PM CDT Fri Sep 18 2020 Valid 190100Z - 191200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe weather is unlikely across the USA through tonight. ...Oregon... Only meager convection has formed beneath the upper trough over central Oregon, with a few storms into southwestern Washington as well. While temperatures aloft are cool, the stronger flow/shear will continue to shift east of the area. Given only 250-500 J/kg MUCAPE as well as the passage of peak heating, general thunderstorm activity appears most likely for the remainder of the period. ..Jewell.. 09/19/2020 NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 0600Z
