Narrative:

Storm with high wind and precipitation forecasted to be on airfield at departure time. Efforts for early go during rapidly degrading weather conditions; resulted in an on-time push. At runway 32; when lined up and waiting; reported wind/gust were in excess of 30 knots with 35 knots gusts; with tower concurring; we remained in position for 12 minutes where reported crosswind was now under 29 knots max. An aircraft ahead of us; as well as two more that departed on the (too short for us) runway 28 reported to the tower; no wind shear experienced. The takeoff; under the circumstances; was normal. Moderate chop to light turbulence was encountered from lift off through 6000 feet. I left my high lift devices in place through the procedure; with a 210 knots max in the initial turns. We were cleared to FL090 for crossing traffic. While proceeding outbound; we were passing 8500 feet in clean configuration at 240 knots. Here we encountered severe turbulence with a massive shear of over 60 knots. Speed went immediately up in excess of 300 knots; red stall margin raised up to the indicated airspeed with pli (pitch limit indicator) appearing on top of aircraft on ADI (attitude indicator). I immediately put throttles manually to max power while keeping wings level and slightly adjusting my pitch with stick shaker activating no less than 3 times at speeds as high as 305 knots with a slightly positive deck angle accompanied by an immeasurable vertical sink rate; we went from at least 8500 feet down to 6000 feet. This was not just a challenge for us; but quite alarming as the 21-mile segment we were on; had a MEA of 7000 feet. My map range was still at 10 miles from takeoff. The terrain display remained green as I looked at it and stayed so during the escape procedure. First officer's radar display showed heavy precipitation in all quadrants. These events were promptly reported by first officer to ATC (severe turbulence unable to maintain altitude). Conditions were violent and required complete focus by all 3-cockpit crewmembers. Once through FL165 we cleared clouds and turbulence. Aircraft wind shear/predictive wind shear warning system did not sound or display. After clearing weather; and assessing that no major malfunctions on aircraft systems; EICAS not showing an over boost of any kind in either engine; and most importantly; no injuries were reported to passengers or crew; the decision was made to continue. Pre-departure public address included warning of rough air and directive of crew to remain seated until advised otherwise.
