Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0656 PM CST Sun Dec 22 2024 Valid 230100Z - 231200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast across the contiguous United States through tonight. ...Synopsis... An upper trough currently exists along the coastal Pacific Northwest this evening, and height rises will occur tonight as the wave moves northeastward across OR and WA. In the near term, a few thunderstorms will remain possible over coastal northern CA, and farther north across western WA beneath the cooler air aloft. Most of the instability is elevated over southern areas, but weak SBCAPE may exist near coastal WA. Here, low-level flow will veer to westerly coincident with the stronger midlevel cooling, supporting non-severe, low-topped convection. ..Jewell.. 12/23/2024
