Rapid deepening of a surface low as it drifts from Ireland and across the Irish Sea on Tuesday evening/night, to then be on the northern flank of the jet stream, combined with the dry intrusion should promote some deep convection on the wrap-around tip that crosses the Irish Sea late evening into NW England during the early hours. The location of this activity is subject to an error bar of +/- 80 miles N-S  but could result in some damaging gusts of wind in excess of 80mph locally - perhaps even capable of producing a tornado.
