Narrative:

A squall line of thunderstorms was developing while we were en route and I don't think the dispatcher or I realized this was going to be a problem when we left [our departure airport] with the dispatched fuel on board. When we reached to west side of the squall line dispatch [messaged] us an alternate that was under the squall line. They also requested a voice call thru operations frequency which I made and he asked if I got the added alternate. I said yes and told him we would fly north on the west side of the squall and that there were several good size holes which I was sure we could get thru to [original destination]. As we flew north each hole we planned to fly thru closed up on the radar screen. With our eyes glued to the fuel gauges we turn east on the 4th hole just north of [destination and] made it thru with moderate chop and got cleared direct on the east side of the squall line. The FMS was showing us landing with 3000 pounds of fuel. The first officer and I were ok with this since [the destination] was still VFR. [Nearby airports] were also VFR but the weather was getting close to [our destination]; adding some more stress to the situation. We landed with 2;800 pounds after declaring min fuel at 4000 pounds earlier with approach. They said we were number one to the field and we proceeded directly to the marker. This is the lowest fuel I have ever landed with in an airliner and I will certainly be much more conservative in the future. I.e. Go to an alternate.
