Narrative:

My co-pilot and myself repositioned 1 aircraft from ZZZ1 to lns. Once we arrived in lns, we swapped aircraft. We performed a preflight on the LJ35, as well as a preflight WX briefing. During the WX briefing, we became aware of 4 thunderstorms that was in close proximity to lns airport. The decision was made to taxi for departure. Once we began to taxi for runway 26, heavy rain began. The tower gave us clearance to taxi into position and hold on runway 26. Once in position, we began to observe the radar. As a result, we waited in position for approximately 15 or 20 mins for the thunderstorm to subside. After heavy rain turned into light rain and the visibility on the airport improved, we decided, as a crew, to depart runway 26 late at night. On the takeoff roll, approximately 5-10 KTS below V1, the aircraft quit accelerating and directional control was compromised and the decision to abort the takeoff was made. The aircraft came to a stop approximately 50 ft left of the centerline in the grass. At that point, the aircraft was evacuate/evacuationed. We moved away from the aircraft to the airport terminal and proceeded to make the appropriate phone calls.

Narrative: MY CO-PLT AND MYSELF REPOSITIONED 1 ACFT FROM ZZZ1 TO LNS. ONCE WE ARRIVED IN LNS, WE SWAPPED ACFT. WE PERFORMED A PREFLT ON THE LJ35, AS WELL AS A PREFLT WX BRIEFING. DURING THE WX BRIEFING, WE BECAME AWARE OF 4 TSTMS THAT WAS IN CLOSE PROX TO LNS ARPT. THE DECISION WAS MADE TO TAXI FOR DEP. ONCE WE BEGAN TO TAXI FOR RWY 26, HVY RAIN BEGAN.
