Wise choice, I wouldn't risk it. In this area a similar storm bank brings 45-60kt wind gusts, occasional hail, and up to 2 inches of rain in an hour. I waited out an afternoon summer storm at the steel yard warehouse the other day. Glad I saw it on radar before leaving as it capped at 64kt gusts.
As a side note I now put my helmet in a cover before locking it to the bike. Unpleasant sponge.
