1) Strong convection
2) steep llvl lapse rates
That's what you need to really get the wind to perform in these setups. Heavy rain can certainly help with momentum transport, however, the heavy rain also further weakens the lapse rates and can enhance llvl inversions.
It is certainly possible there could be a rouge 45-55 mph gust inland if there are any embedded areas of strong convection. I still think there may be a forced line of convection along the front, but instability seems pretty weak and there probably won't be much, if any, lightning. If anything, this line would help get some gusts in the 35-40 mph range as opposed to 25-35 which will be more common.
