Narrative:
Making our approach into ZZZ we encountered severe turbulence due to high winds and convective weather. During our decent below 10;000 feet the aircraft was unable to maintain below 250 even though the captain as the PF (pilot flying) was slowing to approximately 220-230 kts steady below. The wind turbulence was severe enough to where we decided to let maintenance know of the issue and ground the plane for inspection. As the pm (pilot monitoring) I made calls out to the captain to inform him of altitude changes while he made changes in power to control the event. After approximately 5;000 feet we got out of the turbulence and started to regain control of our speed and landed with no other events.maintained good CRM while I as the pm was calling out speeds and altitude fluctuations the captain as the PF was making corrective actions to try and control the wind shift and not push the plane past the turbulence penetration speed. [I suggest asking] center for more advisable routes to avoid severe turbulence. We used our radar to avoid heavy precipitation and took an alternate route compared to the aircraft that went in front of us but was still unable to find smoother air.
